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?

Hmmm, I guess "Outlaw" was an appropriate name for it.

Did you get your subs working yet, via speaker wires to sub and out of sub?

I just re-read your OP, and out of curiosity, what is your second sub?

And your original (first) sub?

And also, since I am ASSUMING that your original single sub was hooked up and operating via speaker wire connections, is it at all possible that a problem is existing with the second sub that is causing the fuse to blow?

Okay, so that’s a low pass filter, which, if I’ve got this right and your sub is the same as mine, is the adjustable part that sets where the frequency that the sub reproduces will be cut off at..

"A low-pass filter (LPF) is a circuit that only passes signals below its cutoff frequency while attenuating all signals above it. It is the complement of a high-pass filter, which only passes signals above its cutoff frequency and attenuates all signals below it."

"I hooked them up was I went from the SUB SPEAKER OUT from both subwoofers"

You want to go to the sub INPUT not the output. Unless that was a misprint in your original post, using the output on the subs would blow a fuse.You would be directing the sub amps back into your stereo amplifier.

Grizzly, I am confused (but that doesn’t take much) picture 1.

I’ve never hooked my sub up via speaker wire, but I save all my manuals, so I just went to my M&K sub manual and looked at it, and it appears as if they are saying to hook up as you show in picture 2.

Left + & - out of amp goes into left + and - i "from sub" inputs in subwoofer.

Right + & - out of amp goes into right + & - "from sub" inputs in the sub.

At the sub, in my manual, it shows two sets of (one for L and the other for R) TO SPEAKER outs.

I am not understanding how you wired it in pic one.

I could scan the diagram in my manual and attach it to a reply if that would help?

But on edit: being computer illiterate, I don’t see how to include an attachment on this site?
