Rockford Fosgate Power Amp

Rockford Fosgate Prime Amplifier Series Review

Introduction

This is the 3rd and final instalment in our Rockford Fosgate Amp review series. Previously, we had a detailed look at Rockford Fosgate Prime and Rockford Fosgate Punch series of amplifiers.

In this article we will be taking a look at some high-end audio amplifiers - more specifically the Rockford Fosgate Punch range.

If you have progressed to this level of audiophile and can still hear your neighbor yell at you to turn it down, we can safely say that you are not deaf yet. Keep it that way by practicing safe sound. Unlike the hair on your head, those inside your cochlea do not grow back. What’s a cochlea? It’s that part of your body that puts the hear in ear.

General Assumptions

Given you are looking at this range of amp, we assume you have some knowledge of an amps role in an audio system. We also realize that some may be reading this for learning purposes so we will try our best to balance the article well.

We assume that you know your ohms from your amps and that these two are inversely proportional to each other. One goes up, the other must come down. Heck, they even have a name for it in electrical engineering, they call it Ohms Law.

A final assumption we can make is that you do not mind to pay for quality. Yes the Rockford Fosgate Power amplifiers are expensive, but you get what you pay for. Taking a look at the internal construction of these amplifiers you can easily see why they cost more. Everything inside there screams quality and it does so with crystal clarity.

So, to kick things off, let us have a look at a subrange we like to call portable power. A lot of people contacted us after the last article stating that these small-factor amplifiers should be in a category of their own.

Full Review of Rockford Fosgate Power Amplifier Series:

Rockford Fosgate Power T750X1bd

Yes it’s true. Rockford Fosgate listens to its customers. Here they have proven it yet again by delivering an exceptional product in a sleek, portable package. Ideally suited for vehicles that are not used frequently, like boats or even golf carts, these amplifiers comes loaded with features and clarity.

Their small form factor and Molex plugs allow them to be easily removed when not in use. Not only does this save you the hassle of caring for an amplifier exposed to the elements, it also allows you to move the amplifiers between different vehicles.

Their internal construction is not 100% what we would have expected to find inside a Rockford Fosgate Power, but they are still pretty solid. High quality components designed by Rockford themselves grace the inner cavity, whilst crystal clear sound flows out the other side.

This range is primarily a D class amp, fine-tuned for optimal bass performance. Speakers as low as 1 ohm are supported, meaning that you will get maximum punch for your buck. We should add here that quite a few bucks are needed here. But as we warned earlier, these are serious sound, not starter kits.

Rockford Fosgate Power T500X1br

As with the portable amplifiers in the lower ranges, these amps also support online high level input, which can be adjusted depending on your input level. The Rockford Power amplifiers in this range, offers substantially more control over what is happening with regards to cross-over selection and output levels. This makes moving the system between different vehicles easier, since not all speakers in all vehicles are created equal.

Let's take a look at the pros and cons:

Pros

  • All the units in this sub-range are highly portable as you can simply plug out all wiring. No more tools and frustrations when moving your amplifier.
  • Much more control that the other portable ranges made by Rockford.

Cons

  • Forced cooling may end up sucking dust into the unit.

Our guess would be that if you own a vehicle purposed solely for entertainment, expensive is not a word you use for something costing less than $1000. So yes, even if they are pricey, they make everything sound so good. Crystal clear audio has never been more attainable.

Rockford Fosgate Power T2500-1bdCP

What sets these amps apart from those we had just discussed? Well for starters, they rely on passive cooling. No noisy fans (not that those fans had been noisy), just good old thermally efficient design. Cast aluminium heat sinks and sound design principles means that your amplifier stays nice and cool. Ok, slightly warm maybe, but hey at least you know it is working then.

Rockford Fosgate Power T1500-1bdCP

​Inside these amps you can truly see that it is the best that Rockford Fosgate has to offer. Class bD technology gives you the best that class D amplifiers has to offer, optimized for bass frequencies.

Another great feature these amplifiers have is something Rockford Fosgate calls 'Constant Power'. Speaker impedance can vary depending on what frequency is playing. This feature optimizes the output of the amplifier to take full benefit from this, putting out maximum power and clarity over the whole frequency range.

Rockford Fosgate Power T1000-1bdCP

​Custom designed components like audio transformers, inductors and MOSFETs means that these amplifiers are much more expensive than a Prime would have been but, you will soon see, and hear, that you get what you pay for.

Talking about the Prime, we remembered how large and relatively light it felt. Indeed when doing a side by side comparison you can see that the Power amplifier is much smaller and weighs in higher than the prime. This only goes to show how much more consideration has been put in to manage heat and component layout.

Rockford Fosgate Power T500-1bdCP

​On the feature side, you would find all the things that you have come to expect from Rockford. RCA pass-through, top mounted controls, CLEAN tuning technology and finally the Punch Remote plug.

It seems that there is not much difference between the Punch and the Power here, other than a more robust design and the quality of the components used. It does seem that even the lower powered subwoofer amps supports 1 ohm loads, something that has not been the case in the other ranges.

​So what are the good and the bad on these amplifiers?

Pros

  • The variable Butterworth crossover is now 24dB / octave (in the Punch they had been 12).

Cons

  • When installing the larger amplifiers in this range, consideration needs to be given to your car’s power system. This is not really a con, but a lot of people forget this and realize only when damage has already occurred.

All and all we love these amps. The sound quality is really something to behold.

Something we would really like to ask is the following: Bigger is better, right? Well not entirely. Although we really love the pure power from the 2500W, the cavity inside our car is simply too small to really enjoy this power.

Here you should really employ your own good judgement. Do you want to win sealed car sound competitions, or just enjoy the music? We know that 2500W can be enjoyed - just do it safely, ok?

Rockford Fosgate Power T1000X5ad

These amplifiers differ somewhat to the single channel compacts in the sense that the minimum supported impedance is 2 ohm. When considering the internal built quality, they are mostly the same.

Like the monoblocks, these Rockford Fosgate amplifiers also use forced cooling. This can become somewhat of a problem to some, but given its small frame, it is a necessary evil which we would just have to accept. Disconnecting them will result in the amplifier overheating, producing poor quality sound and eventually going up in smoke.

​This is not to say that this range of amplifiers cannot be enjoyed. They do wonders if used correctly. They may not have all the features the other amplifiers in the Power range have, but when taking a look at their design purpose, these amplifiers pass with flying colors.

Rockford Fosgate Power T400X4ad

​Taking a quick look at the portability of these amplifiers one can easily see that the 5 channel T1000X5ad comes out right on top. Where the other amplifiers in this range have screw based power connectors, the Rockford Fosgate T1000X5ad also has plug in connectors. Fortunately they are of a different design than the audio inputs, so no confusion will ever arise as to the correct socket to connect to.

Rockford Fosgate Power T400X2ad

​Something that is also worth mentioning is the topology these amplifiers function with. Class AD technology ensures rich sound while still keeping the amplifier as energy efficient and powerful as possible. When considering the size of the build-platform, this had been an excellent choice on topology.

In this range the standard of 2 ohm connections also applies. However, there is one major breakthrough for the 1000W 5-channel version which comes in the form of the subwoofer connection. As you would have learned by now, Rockford likes their subwoofers to run as efficiently as possible and nearly always tries to support 1 ohm loads when powering subwoofers. Good news for us sound-junkies I would say.

Pros

  • Great features in a small package.
  • High level inputs with CLEAN technology.

Cons

  • Forced cooling can end up allowing dust to enter your amplifier.

Rockford Fosgate Power T600-2

For most people progressing to something as good as the Rockford Power range of amplifiers, loud is not always the deciding factor when considering a system. But it is still nice to have something that you can turn the volume up. Entertain the neighbourhood, if you so wish. And it also doesn’t break the bank.

Standard, this amplifier comes with everything you would expect to find on a high-end product. 24dB / octave Butterworth crossovers adjustable to your liking, CLEAN technology, and pass-through connections allows you to expand your system to your liking.

Rockford has yet again proven that they are one of the leaders in audio technology through this amplifier. Excellent thermal management and quality components features throughout all the amplifier stages.

Rockford Fosgate Power T400-2

​Connecting this amplifier, you will find that it can accommodate 4 gauge wiring, allowing you to really draw some current. This in itself is already a selling point for us. We tend to connect our amplifiers in parallel using the connectors on the amps themselves. Having large connectors to work with makes our job that much simpler.

​We would definitely recommend these amplifiers to anyone looking to upgrade parts of their system. If you want the best new system possible, we would aim a little higher, but for anyone wanting better sound, this is an ideal stepping stone in the quest for greatness.

Pros

  • Supports all the features of the higher priced amplifiers in this range.

Cons

  • Longevity of this amplifier could be limited due to its output.

Rockford Fosgate Power T1000-4ad

Contained here is what we might consider the flagship of Rockford Fosgate's amp range.

Something that is worth mentioning though is the fact that no five channel amplifier exists within this range. Enthusiasts on this level have grown to be quite a strange bunch of people, so we guess they prefer not to have it. Doing some introspection, we noticed we too seem kind of strange.

Rockford Fosgate Power T800-4ad

Rockford realized that high-end consumers tend to prefer a component based system and that exactly how they set these up. In our eyes this has been a wise decision considering heat management and component spacing. Having a high powered subwoofer amps bundled with a high powered stereo amp would eventually spell disaster. It also gives us a strange satisfaction having two high-end amplifiers installed that we can show our friends.

Fortunately Rockford deemed it wise to also enable channel bridging on this range, so if you feel the need, you can run a stereo setup together with a subwoofer from these four channel amplifiers.

Rockford Fosgate Power T600-4

​Feature wise you could ask for nothing more - Class A quality sound combined with Class D efficiency. This however is only the case for the Class ad amplifiers as you guessed. Not that the T400-4 and T600-4 are substandard of course. In fact, they are nothing short of amazing; they just don’t have that distinctive Class A sound to them. Not everybody likes the added room a Class A amplifiers gives, so that’s not necessarily a bad thing.

Rockford Fosgate Power T400-4

​Something else to note is that the T400-4 and T600-4 supports a minimum load of 2 ohms per channel. The T800-4ad and T1000-4ad blows this out of the water by supporting a 1 ohm load however. This is, in our view, a really great selling point for the ad amplifiers. Never before have we seen an amplifier of this quality and price support 1 ohm loads across all four channels.

Pros

  • The higher end of this amplifier subrange supports 1 ohm load across all channels.
  • Truly aimed at a component based system.

Cons

  • You might have to trade in a body part to own this.

​So the true question is, will we keep any one of these amplifiers for ourselves? Oh yes, we will. Mind you, we already tucked the wires away neatly on our T1000-4ad installation. This means we are going to leave it just where it is for those of you that do not know us.

Conclusion

In this article, we've taken a thorough look at Rockford Fosgate's, high-end audio, Punch amplifier range.

To recap: The T500X1br and T750Xbd Portable Monoblock Amplifiers are a great choice for those of us looking for a portable solution and are ideally suited for a subwoofer. The T500-1bdCP, T1000-1bdCP, T1500-1bdCP and T2500-1bdCP Mono Amplifiers are higher end options also ideal for bass.

The Class-AD line of amps: ​T400X2ad, T400X4ad, T800-4ad and T1000X5ad Stereo / Multi-channel Compact Amplifiers provide great features in a compact package, and are super energy effecient, making them ideal for hybrid / electric and smaller cars.

We rounded things off with the the T400-2, T600-2 Stereo Amplifiers, and the T400-4, T600-4, T800-4ad and T1000-4ad Multichannel Amplifiers - these are the ultimate choice for high end component based systems.

So ultimately, when it comes to choosing from one (or more) of the above, really it comes down to the type of vehicle you are purchasing for, your budget, and what components you are planning to pair your amp with.
