PRV Audio QS800.4 2 Ohm Compact 4 Channel Car Audio Amplifier 4 x 220 Watts RMS at 2 Ohm - 800 Watt Amp High Power Stereo 12 Volts Amp Class D Full Range Bridgeable

So far a good addition to my system

Very loud didn't play well with 8 ohm horns had a lot of engine noise. But I hooked them up together with a pair of 4 ohm speakers played well.

I installed this QS800.4 2 Ohm compact 4 channel car audio amplifier in my Jeep, and it sounds great. The amp delivers 4 x 220 watts RMS at 2 ohms, providing high power and clear, dynamic sound. The installation was straightforward, and the compact size fits perfectly in my vehicle without taking up too much space. The Class D full range and bridgeable design offer excellent versatility for different audio setups. The build quality feels solid, and it handles high volumes without distortion. The price is reasonable for the performance and power it delivers . Overall, this amplifier has significantly enhanced my Jeep's audio system, delivering impressive sound quality. I really dig it - great amp for a good price.

Tested this out on one of my car setups and honestly, I'm very impressed.Highs, mids and lows all sound pretty good, and after running it for almost an hour it never got too hot to touch.It did get pretty warm, but I had all four channels running loud and there were a few songs with a lot of bass.

Impressed with this amp! Compact design packs a punch, easy setup with clear labels. No struggles keeping up with the power demand. Great addition to my system!

I used the 4 channels to push more power to my 6 1/2” mid in my front doors and my 6x9 mid bass speakers in the rear door panels to get better sound quality. You can bridge the channels and will push out enough power to run two 10” or 12” sub woofers. Great value and power for a low price.

I like that this amp is very compact compared to others with this much power. It’s easy to hook up and the inputs are clearly labeled. I haven’t seen it struggle to keep up at all.

When I got it, I noticed it didn't have the plastic around the inside of the amplifier, no pamphlet or a sticker, which is really rare for P.R.V. I decided to hook it up anyway. Considering it was pretty cheap, I didn't care that it was used but channels three and four did not work. It made my d s p shut off.I had to reset it. Sending too much feedback through the rcas. It almost fried my deck.
