I am looking to get a high powered amp with rca, or lfe connections for under $400. the cheaper the better. it has to have at least 1000watts per channel rms. Behringers epx series are the only amps ive seen so far that meet those quality's. so I am considering getting a epx2800, epx3000, or epx4000. their website says they come with a standard 3 year warranty, and there are some good reviews out there, but there also seem to be some people who haven't owned the amps, but say they arnt very good, so idk. are there any other amps out there that would work for me in my price range? im trying to hook the amp to a Yamaha RX-V375 receiver, and the receiver's only audio pre out is a LFE out for a subwoofer. I have been told I can split that and connect to regular rca inputs, but don't know of any way to connect to other amps. I need to decide soon, because I am planning on returning my current JBL ES250p subwoofer that is somewhat disappointing. Thanks in advance.
