BOSS Audio Systems R1004 4 Channel Car Amplifier, 400 High Output, Class A/B, MOSFET Power Supply, Hi-Low Inputs, Full Range, Compact 9 Inch Chassis

[This review was collected as part of a promotion.] Nice little amp to run my mids. Sound quality wasn’t bad considering the price. Power was good too for my 4 6.5’s. Size wise was perfect because I was able to mount it right behind my box. Good small budget amp.

Replaced a high dollar failed amp with this. It installed easy, and it works perfect for our application. It is about half the size of the old one. I am running 4 very small ceiling mounted speakers inside a motor home. We use our radio system to primary run our tv through, works perfect. Sounds great.

Good quality . Excellent value .

Works real good I have four speakers connected great install sounds real good

[This review was collected as part of a promotion.] It comes well packaged with everything you need. Pretty easy to install as well! It’s an average sound quality but seems pretty sturdy. Good value!

The amp has a feedback issue I had to purchase a boss audio noise distorter to fix the issue.

[This review was collected as part of a promotion.] My husband pit it in his truck. It's ok for small speakers of course. I probably wouldn't purchase one though to be honest not a super great Amp but it's ok

I set this up on my 92 Sierra Regular Cab, to 4 4x6 speakers. It got the job done, it works, but it does this eery, high pitched sound when you turn your truck on, and that sounds stays on and it goes with your engine, so if you press on the gas the sound goes higher, and i saw many people's reviews complaining about this but i wanted to see for myself and it was true, it wasnt my wiring either. But when you have your music at high volumes you can't really hear it. You get your 30$ worth, but if I were you I'd put a few more bucks into a better amp.

this amp is garbage. you hear all road noise. I ran everything the way you should,and it still loud. this is the second month having it and already burned up. not worth the money

Had to give a one-star review because the unit came broken and I had to return it.
