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.

RCA or LFE, either will be acceptable to you? You sure about that? eek.gif

Cheap is good, as long as it's awesome. That'll get you far....rolleyes.gif

You still live at home? iBurp perhaps? tongue.gif

Oh, and the subwoofer preout is pretty much that...who is telling you all this crazy stuff? You should kick them in the nuts.

What's the problem in your using the sub? The sub is self-powered so the separate amps would not help you with the sub, but of course you knew that.

Deciding now?

people on this site have told me that, in fact, reading more on this site, it seems I can use a rca to xlr and connect to any amp. the sub is pathetically quiet and lacking in the earth shaking bass I am used to, so like I said, I was going to return the self powered sub and buy an amp and build my own enclosure with an 18" sub. so if you know anything that might help, that would be great, but you can go ahead and keep the childish remarks to yourself. "iBurp" for real? haha

Here is a single pin rca to xlr cable. This will work with a/v receiver rca bass notes out (subwoofer or lfe)
to pro amp xlr in. And Behringer is the cheapest brand that will put out that much power. There are other
brands and better amps, but not for that low of price.

thanks. the main reason I am doing this is because I found someone selling 2 Rockford Fosgate P3D4-15 subwoofers for only $70 each. Which are pretty good car subwoofers that would typically go for more than twice that. they are actually what I was going to put in my car, but i got upgraded to T1D212s for free. im putting it all into winisd right now, and it seems to be indicating that with the properly constructed box, that i should be able to get down to 15hz. i don't know if my receiver even out puts signals below 20hz though, so not sure if i should even tune it that low. also there is a guy selling a Crown CE2000 amp near me, and he wants 225 for it. is that a good amp? the subs are rated at 600watts rms each and 1200w peak each. will that amp be enough to power them? i would assume so if the 2000 stands for 2000 watts rms, but idk if it does. from what ive seen so far, allot of home audio wattage ratting are completely imaginary, or are peak worded to suggest they are rms. if i go that route though, the amp doesn't appear to have normal speaker outputs, so i would have to get some type of conversion wire. sorry for the long post.

Crown makes fine pro amps. Not all pro stereo amps can bridge both channels into one, but this model can. That is generally preferred for
driving subwoofers. Most pro amps have xlr and 1/4" inputs and speakon connectors for the speaker wire connection.

Monoprice has them also. Here is just the plug that can be attached to regular speaker wire.

Here is speakon speaker wire. Guess you just cut off one end?

Pro amps are rated with realistic numbers all channels driven. Most home consumer amplifiers are rated
with real numbers also. Almost all consumer a/v receivers only put out rated power with only 2 channels powered.

I ended up getting a used epx3000 for cheap. the fans are pretty obnoxiously loud tho, so im going to swap them for a pair of these. http://www.digikey.com/product-search/en?WT.z_header=search_go&lang=en&site=us&keywords=P14751-ND&x=17&y=12
this amp should have plenty of power. for the P3 subs
