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?

Ok so this would only work with the Y splitter - in the preamp - amp scenario?

for the mains - preamp to Y splitter to 100Hz high filter to amp to mains

for the subs - preamp to Y splitter to subs / subs low pass set at 100Hz

As emphatically as possible:  NO!!

(Give me a couple of minutes; I'll come back to this.)

Envision it this way: high pass filter INSTEAD of ’Y’ splitters.

FROM the preamp L & R RCA outs

TO the high pass L & R RCA ins

FROM the high pass there will be two sets of RCA outs

one set of RCA outs from high pass will be designated ’sub’ and obviously there will be a set of RCA cables from there to subs. This will be a full frequency signal that will be edited by the sub’s low pass.

The other set of RCA outs will be designated as ’amp’ (or something like that ) and that set of RCAs will go FROM high pass  to the amp. It is this set of RCAs that will carry 80 hZ and above (if that is what the high pass is set at).

@immathewj

this is the high pass filter, I don't see two sets of outputs

You would need one per speaker! Are you sure that you are not mixing up a high pass filter with a high pass xover?
