Rockford Fosgate 400 Watt 4 Channel Bridgeable Class A/B Amplifier Power T400-4
The T400-4 amplifier is another super high quality powerhouse from Rockford and is perfect for front/rear fading stereo systems or when dedicated amplification is required between front stage speakers and rear subwoofer(s). Thanks to the Dynamic Thermal Management cooling system, the small chassis design insures it can be installed in any location - like under front seats. The "Differential Input" circuitry helps eliminate any electronically induced noise or hum that could be picked up by the input cables, allowing only clean signals to enter the amplifier. This is a great compact amp that runs cooler and delivers the legendary Rockford performance you have come to expect.

I’ve owned many subs in my 40+ years,and this is a definite gem! Got this sub In April of ‘23,finally finished installing everything in my Cadillac Deville in June. Ran single 3015 at .5 on aak 4k until October ‘24. I was not easy on this sub at all! It took every bit of that 4k and laughed. Great range and great sounding sub. Took it out of the box it’s been in for over a year playing daily (did a 148.8 from the trunk of a bigass Caddy) and the coil looks damn near new! I will definitely be buying another Deaf Bonce sub in the future!
Does exactly what it says...clear legible display, quite accurate readings. Everytime I tried to order from them, it was sold out. Not with Big Jeff...in stock...took about 3 days. Boom!!
This sub justifies the parameters for my application. I have limited trunk space,just enough for 2 of these. I put a hole in my strut tower with a 9512j back aways from there I swapped it with the very 1st 2508,so I already have experience with this project,I’m a bass and drift cars enthusiasts and appreciate the value of performance and form factor.
