Yes or, if you prefer, left preamp out to left amplifier input and left subwoofer line-level input, and right preamp out to right amp input and right sub line-level input. Good luck.
speakers and cables
this is about me being a loser and problem creator.
I finally got a 2nd subwoofer and I was excited to hook it up. Well, not too excited. I knew it would be a pain to hook it up. I was excited to hear it. I spent over 90 minutes connecting the speaker wires to my power amp. When I turned it on, the left channel was gone. It blew the fuse. I disconnected everything, replaced the fuse, hooked it up again. It worked for 10 seconds, blew the fuse again.
The way I hooked them up was I went from the sub speaker out from both subwoofers, rolled the left and right side wires together so I had 4 wires that I connected to the left and right plus and minus channels - speaker binders on the power amp. What are my options? My preamp has no sub out. Nor my amp.
Stupid question: should I just go from left to left on one sub and right to right on the other sub?

Sorry, @grislybutter , for the confusion. Although I understand and respect that this is not an option you presently want to consider, I still feel compelled to do a better job of explaining it. Okay, your L & R RCAs outs FROM preamp would go TO the L & R RCA ins in the high pass filter. The high pass filter would have TWO PAIRS of RCA OUTs. The high pass filter would send the full frequency signal to the subwoofer via the pair of RCAs designated subwoofer, however, the high pass would only send an 80 hZ and up signal out of the pair of RCAs designated speakers, and these RCAs would connect to your amp. So if you think about it, now your amp is only reproducing 80 and up, and therefore your speakers are only trying to reproduce 80 and up. Back at the sub, which is getting a full frequency signal from the high pass filter, the user would probably set the adjustment (and this would be the low pass filter that one would adjust on the sub) to 80 or 85 hZ to start with. So what one would be doing, in theory if it was a clean chop off of frequencies, is having the sub reproduce everything exactly under 80 hZ and having the speakers reproduce everything exactly above 80 hZ. In a perfect world, there would be no overlap between the sub and the speakers. (And also, even in a less than perfect world, both the amp and the speakers are now free of the work of trying to reproduce frequency below 80 hZ which should free them up to do a better job on the higher frequencies.) But they tell me it is not a perfect world, and it is not a clean EXACT cut off at 80 hZ and therefore the adjustment at the sub (the low pass filter) needs to be played with and tweaked a bit, usually starting at around 85 hZ. Hopefully I was able to clarify that & clear up any confusion I may have created. However, much simpler, as @mitch2 just said, would be an RCA ’Y’ splitter at each RCA out of your preamp (L & R). From left one RCA would go to left RCA IN of your amp and also to the RAC IN of your left subwoofer/and then the same for the right.

@mashif my bad - I do have an out from my preamp. I call preamp out from integrated amps - but you are right. So yes, that’s a good suggestion
@immatthewj thanks for the clarification. It wasn't your fault, I am easily confused. Your explanations are always very thorough. I am looking up Y splitters now on Amazon. |
