Product Description

(It's one of our ultra-compact models. The size of this painting is 6" x 4". The size of the sheet is 3 This 4 channel amplifier for 3") Power T400X4ad produces more power per square inch than any other model made by Power with 400 Watts of Power
Constant Power amps are the most powerful on the market, delivering up to 25% more power across all impedance loads (100 Watts x 4 @ 4-Ohm, 100 Watts x 4 @ 2-Ohm or 200 Watts x 2 @ 4-Ohm bridged).
Powered by proprietary Class-AD technology, Constant Power delivers the same output at both 4 ohms and 2 ohms, so it's best suited to hybrid, electric, small and heavy vehicles, trucks, motorcycles, and UTVs.
The POWER of T400X4ad is its high-level auto-on and CLEAN circuit input/output clip detection, as well as a Punch EQ with +18dB boost @ 45Hz and a crossover with 12dB/octave.
With world-renowned Rockford Fosgate build quality, you can be sure this projector will handle whatever the task may be. A 2-year parts and labor guarantee is included with every Rockford Fosgate computer purchased from a dealer authorized by Rockford Fosgate

Questions & Answers

Do you realize that these are only microamps? Is it possible to use it with a car, not just a bike?

It is true that you can use them in the exact same way as a normal amplifier. Since they are large and often used in settings with limited space, they are often used in very small settings.

What kind of wiring does this amp have? Seems like they used something else on the amp in place of the RCA plug?

This amp has those RCA plugs on a molex that plugs into Moreover, I am able to offer you a very competitive price on this unit and all items needed for installation. I can also be reached by text From 750 to Please call 87726 for a price I appreciate it!

Can the 2012 victory cross country be mounted on a mounting plate?

There is unfortunately no mounting plate included. You would have to fabricate one for yourself. Please accept my thanks for your interest.

The sound quality on this unit is better than Rockford's Prime line up?

I say yes! Yes, both are my own and the sound is so much better with the power series'

Selected User Reviews For Rockford Fosgate T400X4ad Power 400 Watt Class-ad 4-Channel Amplifier

This is an excellent product that is significantly I really like this amplifier! Initially, I had just one, but now I have a number Originally, these small Rockfords cost $800 or more
5/5

In the beginning, they were half that size, but they dropped to half that size as production increased. There is a very high end system consisting of ten (10) channels in which my amps are located A total of eight (8) of which pass through two of these amplifiers. On the whole, the system is about a $15,000 stereo, and this amp has all of the quality you'd expect from a system of that calibre. By using the amp's info lights, you can set the gains to safe levels without using an external device, so installation is fairly simple. Don't be fooled by its small size, this amplifier packs quite a punch in terms of performance. In fact, it's not that there is less amplifier in it that's small. This is because the cooling process is active as opposed to passive (i. e. A cooling fan is attached to it). The heat is not spread widely, which means it can be concentrated in a small space. The only component that needs to be installed is a heat sink, because fans just blow heat away. There are no problems with the electronics, and the cooling solution allows for a smaller size.

The main reason is that it can run at 4x the power of other 4-watters. The Constant Power circuitry is responsible for the channel amps. There won't be any difference in volume when you run 4 speakers, regardless of their impedance load. It's like placing an impedance load at the end of a wire - it's the same. Maintaining your amps at a cool temperature will not result in any noticeable sound volume loss. It's amazing how good this product is!.

Thanks for a great job
5/5

The accompanied birth certificate shown the amplitude of my 2018 Street Glide amp. I am extremely impressed with the finished product. I am glad I added the amp to my Glide. Another company does include a Birth Certificate in their amplifier, but I am not familiar with them. It took less than an hour to install the amp, which came with all the wiring needed as well as a CD which could be transferred to a thumb drive to properly tune the amplifier. The Rockford Fosgate Saddle Bag Speaker kit and the 6 were also added. The fairing speaker has a 5-inch diameter. In comparison to stock speakers, there is a significant improvement in sound.

The sound is amazing! Besides this amp, four rockford speakers, and a wiring kit with a heat sink you do not need anything is amazing to listen to, and even at 75 mph it is still loud enough to hurt your ears at high volume

This is incredible.

I love it on my 98 Harley Davison
5/5

The only problem with it is the brackets kit to put it on top of the radio do not work. I had to Velcro it to the top radio as they swore that bracket would work. Other than that, it sounds awesome.
