Great sound for a great price

Great amp, powers my Pioneer TSDs 6.5" and 6x9" with ease. Sounds crisp and clean without trouble. Would recommend to anyone looking for great budget amp. Have had it for over a year now without any issues.

Great Value

I bought this REP4-900 to replace a Polk Audio PA660.4. They have similar power output and both sound clean, but the Power Acoustik amp is $100 cheaper. I wish I bought the more powerful REP4-1200 for $9 more.

Nice Amp

For the money,this is a nice amp.Got this amp paired up to 4 6x9 Audiobahn 3way.This amp does the job and has a clean sound.I would recommend this to anyone.The bass and highs is great,some people think I have a small sub in my car.

Replaced my PA LT720/4

I was noticing that my music was sounding muddy so I purchased the REP4-900 to replace my Power Acoustik LT720/4. The new amp was definitely cleaner sounding but does not have the easy access controls and lacks a couple options versus their older amp.

Still, the performance of this amp is far greater than you would expect for the price.

Gets my job done

Loud & Clear. Wish I got this sooner!

This is the first 4-ch amp I've bought and I wish I got it years ago. I use this to power a couple PA 6.5" mid-bass speakers in the front and the stocks in the rear (I plan on replacing them soon). This thing is crisp, clear, and loud compared to any stereo I've ever heard. I have to turn down my bass a little so I don't distort my speakers, but it's still painfully loud. I don't think I'll ever turn this all the way up. Definitely recommended!
