The Rockford Fosgate T400-4 Compact Car Amplifier brings serious performance in a surprisingly small footprint, making it a perfect match for car audio enthusiasts who want clean, controlled power without wasting space. Built with an advanced cast aluminum cooling system that improves heat dissipation by up to 30%, it stays cool and consistent even when you push your system hard. With intelligent thermal balancing and MEHSA³ technology working behind the scenes, this amp is designed to keep your sound strong and stable no matter how long the drive gets.
What makes this amplifier stand out is how clean and precise it keeps your music. The Trans-ANA signal path delivers ultra-linear amplification so your sound stays detailed and accurate, while DSM precision engineering reduces noise and keeps everything running efficiently. NOMAD intelligent protection constantly monitors your system in real time, adjusting for temperature, voltage, and load conditions so you get maximum output without worrying about damage or distortion. It is power you can trust, even when you crank it up.
The T400-4 is built for flexibility with a 2/4-channel switch that makes installation easier in different setups, whether you are running a full system or bridging channels for extra impact. Wide-range active crossovers let you fine-tune your sound from tight mids to deep lows, while the adaptive Punch EQ gives you real control over bass and treble depending on how you set it. Add in heavy-duty power terminals, high-capacity speaker connections, and optional remote tuning support, and you get an amplifier that is not just powerful but also incredibly easy to dial in exactly how you like it.

Rockford made amazing amp.running this with my rainbow slx265 deluxe .small size ,clean ,powerful amp.
Had a Hifonics ZXi 6406 pushing my 6x9s before I got this. First of all, the Rockford barely gets room temp where the Hifonics would go into Thermal Protection. A tad pricey, but that's the cost of quality. Like all Power Series Rockfords, you buy it for the quality, the power and for life!
I have one of these powering the rockford T1 components in my front doors and the T1 coaxials in the rear. Amp never overheats and I live in Florida where the summers easily get to 90 degrees. Would recommend this product to anyone.
sounds good never overheats ,had them on my focal polyglass 6.5s 1 pair comp 1 pair coax.. the only thing that i guess is why its not perfect is that i noticed allot of "fuzzyness" whn no music is played,so ofcourse it still does it while theres music.. i noticed that this amp has like 1% thd (total harmonic distortion) and i am no genious but i try to educate myself as far as possible , i believe that the 1%thd is kid of allot considering that other amps may have as little as .05% , thats way less . I had an alpine pdx 1000.1 on my alpine type x 12, and it woulod overheat fast m it had a low sensitivity ,it wasnt efficient at all and always overheated. while my sub and amp would crap out, my mids stayed bumping loud and clear ALLLL day long ,hgours and hours and hours full blast .. this amp wont crap out. if i could find a amp just as good without the high thd i would go witht that,but the rockford is also really good.
this amp kicks a**!!! for the price and size of the amp u cannot beat it!!! great sound and punchy midbass. have it runnin 6.5 comps in front and bridged on midbass woofer in back. have used rear outputs for 12in sub too. sounded great that way too. nice clean power !!!!!!!!
I got this amp hooked up to 2 alpines type R's 100watts RMS, for the front door of my 98 civic and 2 6X9 O2's power for the rear deck, and the gain on it is at 4, and my friends can hear my voices from 2 blocks down my house. Best amp I've ever owned, I will recomend this amp to any body wants to hook up a good stereo system. From: Ansonia CT, baby
