T400-4

The T400-4 amplifier 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, the small chassis design insures it can be installed in any location – like under front seats. This unit is a 4-channel amplifier capable of producing 100 Watts into each of its four channels at 2-Ohms. This can run a 4-way full-range system or use component speakers on the front with subwoofers on the rear.

WOW, very good performance

Origionaly intended to use the amp for my components but I ran out of money for toys so I am now stuck using this amp to power 2 Dayton Audio 15" reference subs temporarily. The subs are severely underpowered however they still sound fantastic. The birth sheet that came with the amp rated it at 'nearly' 500 watts RMS. Even when driving the amp at its peak output the distortion is minimal (would still not recommend it though). The only problem I have at all with this amp is that Punch EQ 18db adjust knob (only bass control knob that is compatable) can only adjust the rear channels. Not a big deal, I wouldnt use it anyway if it was on the components. The heat dispersion plate works well but if you have it in your trunk with no air circulation it will still overheat after about an hour IF running near full power.

For my ratings,

Value - was a 5 because Sonic Electronix has some of the best prices I can find from a higher end online dealer and I paid less for this amp than I would have for 400 RMS watt at walmart (not sure if walmart even knows that they are supposed to rate an amp at RMS not peak)

Look/design - 5 because I like simple asthetics, I dont need a bunch of flashy lights to show off since the only people that care about that are usually the people that dont know anything when it comes to stats and what the thing is for. I would rather show it off to people for its sound quality

Durability - 5 because I run it as close to full power as I can without getting distortion and it has no problem.

Features - 4 only because you cannot control all channels using the Punch EQ knob. They do make a bass control knob that will do that however it is not compatible with the Power series.

Ease of use - 5... plug and play (maybe adjust the gain and boost level a little bit but it sounded great right from the factory.

Amazing power output

Received my amp yesterday and I'm using 4 channel 4ohm output for components. The birth sheet has the power output at 85 whats x 4 @ 4ohm. That's amazing. Sounds great hooked up to my front and rear door type-R components. I couldn't be happier with my purchase. Sonic had this product at my doorstep the next day after ordering.

Good amp for highs.

Once I installed it and tweaked it, I never had to touch it, clear crisp highs. I would reccomend this amp.

Small, powerful, and clean

Huge power, birth sheet says 547w RMS. Incredibly small too. Puts out twice the power my Pioneer 2ch of same size does, and way cleaner too.

Have it pushing my 4 T1682s

Great Amp!

This amp pushes extremely clean power to all 4 channels. I'm running Diamond S600s in the front and Beyma W6 in the rear for mid bass. This amp makes this speaker setup sound excellent. The highs are perfect and the lows are tight and hit hard. I definitely recommend this amp to anyone!

Soooo much power

I bought this amp to power my 4 6.5" door speakers and power them it does. Each speaker is rated at 50 watts RMS at 4 Ohms and I have to turn the gain on the amp way down to keep the speakers from blowing out of the door. The birth sheet shows significantly higher power ratings than is advertised for as well. In my opinion you cannot go wrong with this amp at all.

Rockford t400

I have the T400 powering my focal 6.5 poly glass, it helps them scream to my satisfaction. I have no problem with the amp getting hot or handling my finger going to the volume .
