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?

And overall, the "sound chaos" I sometimes had when I set the frequency on the sub too high is gone.

. . . hmmmm.  Before you were using the speaker wire from amp out to sub and then speaker wire out to mains mode before, right?  So maybe that shoots down my theory about crossover in sub to speaker wire from sub to mains theory making the frequency adjustment on back of the sub inactive.

Now, when it comes to this business, bulbs don't come much dimmer than me.

I'm talking night light here. But, wouldn't you just simply do this:

Wouldn't you just run the speaker wires from the amp to the inputs of subwoofer 1, then run speaker wires from the subwoofer 1 outputs to the inputs of subwoofer 2. Then run speaker wires from the outputs of subwoofer 2 to your speakers?

@carpathian , I am not a bright light when it comes to this stuff, but what the manual for my M&K sub indicates for one sub (using speaker wire mode) is L speaker wire from amp to L speaker wire IN in sub and then from L speaker wire OUT in sub to L speaker. And then repeat for the R speaker wire.

That’s with ONE sub.

But it makes me think that the way to go with two subs is: from amp/to L speaker wire to IN in L sub/R speaker wire out of amp to R speaker wire IN in R sub/and then from L speaker wire OUT in L sub/out to L main speaker/and from R speaker wire OUT in R sub/out to R main speaker.

And I believe that this is the way @grislybutter is presently up & running with.

I need an aspirin...

@thecarpathian,

It’s really not that complex, and I guess I just did a poor job of describing it. My fault.

Instead of the speaker wires going from the amp to the L & R speakers, instead the speaker wires goes to the L & R subs. Then from the L sub to the L speaker, and from the R sub to the R speaker.

(So each speaker is sort of an extension of each sub.)

I am pretty sure that’s the way @grisly is now wired.

I only have one sub, and since I am using the balanced circuit from my preamp in to the balanced circuit of my amp, I used the RCA OUTs in my preamp to go to the L and the R RCA INs in my sub. I've been thinking about it since this thread started, and I think I can see where speaker wire connections from amp/to sub/out to main speakers MIGHT be desirable for myself. But the thing is, I was also thinking, the quality of signal that might give me to my speakers (which is the termination of that signal) MIGHT be affected by the quality of parts in the sub which I am sure is affected by the quality of the sub . . . and my sub is pretty much obsolete.
