Hi,\n\nI recently fixed my JVC ja-s11 (stereo receiver) and would like to use it as the main amplifier in my sound system. My current sound system consists of 2 tower speakers and 1 12" passive sub. The impedance of the sub is 4 ohms and has a rating of 300 watts (I think). Given that the receiver is a stereo receiver, I need a separate amp to drive the subwoofer. On the internet, a lot of people use power amplifiers to get the job done. So I was thinking of buying a Behringer NX1000D and using it in bridge mode because it's cheap (I don't want to spend too much money) and has a built-in DSP (don't know if I need it). My receiver doesn't have any pre-out connections, so I will have to use the rec-out to connect them together. I want to know if hooking up a power amp is different from hooking up a home receiver with RCA and if I have to buy anything else (or if you have a better suggestion). I have had bad luck in the past where almost no audio would come out of the speakers even tho the power amp (without DSP) was a lot more powerful than my home receiver.\n\nThanks in advance!
