### ⭐⭐⭐⭐⭐ Great amp!
*by W***W on 26 September 2013*

I bought this because I was not happy with my new JVC stereo- it did not have the power my old JVC did. Come to find out the old JVC's have a great pre-amp that the new ones lack. I still have old JVC as I still go back and forth about switching it out- only thing that stops me is new has a usb port in front that I use all the time. I bought the amp to power 4 speakers in my 02 Chevy Silverado 1500 ext cab. I have it powering four Pyramid 250 watt (each) speakers- 2 are 5x8's and 2 are 6x9's. It does a great job of boosting the midrange and highs. I went from having to turn my stereo to 16 to get a decent sound level for driving to only turning it to 3 to get the same level now. I have another Boss amp (1200 watt) hooked to my subwoofer. I will say the subwoofer control is not going to boost your sub...it will actually cut power to it. It is nice if you have someone in the vehicle that hates a lot of bass, but other than that I leave it unplugged. What some people do not realize is you have to match watts for watts. If you are trying to run 1000 watt amp to power a 800 watt sub- you will not be happy. It will get hot unless you limit the output. I had that issue when changing to a lower watt sub, the amp would get hot and turn off (I thought it was the sub turning off). I had the audio shop make some changes and now all runs cool and the music is great- OK except to the old people who can't stand the thumps and loud music coming from my truck :)
