Customer Testimonial

I have got to say that Brendan was the best guy down there I have talked to. Brendan knew exactly what I was after, and was able to answer all of my questions. I will be putting my order in within a few weeks, and will definitely be telling friends and family. Thanks again, Lyn.

I got this amp to put behind the back seat of a supercab, It's a great amp but i don't recomend bridging it. I tried that, and in about 15 minutes it got too hot to touch, so I'm getting a second amp for my sub.

I have a '97 TJ and space is seriously lacking. Add to that no security and the high risk of the elements. I needed something just to be able to hear my music and this little amp does the trick. It is insanely small. I was able to tuck this bad boy upside under the drivers side steering column and because it is fan cooled it has no problem staying cool. It is completely out of the elements and is impossible to see without shoving your head up into the dash.



I was a little worried about getting a Sony amp, nobody ever speaks good of Sony, but I have been extremely happy and no issues. I had heard reports of popping and noise with this amp, but I haven't had any of those problems. Just have to make sure you wire the amp up properly, solid ground and don't run wires with other power wires. For the price, power, and size you absolutely cannot beat this amp. I highly recommend this amp for anyone who has a Wrangler and is wanting to hear their music, tire roar, wind, engine, this delivers.

Purchased this around 6 months ago and I am quite impressed. Sits nicely under the passenger seat of the jzx100 or Toyota Chaser. Provides good power to 6.5" door speakers. Not the loudest as it's not hugely powerful but certainly good bang for buck.

These amps are small in size but huge on sound! An excellent deal. I have a pair of these and a pair of the mono amplifiers and they scream! Looking forward to getting more for my next car!

I bought this amp specifically because it was the only amp I could find that would fit under my seat in a Ford Ranger pickup without any issue. I was very impressed with the power from this small amp. I'm driving front component speakers and one 10" low profile sub. My system sounds absolutely awesome. This is a small but powerful amp.
