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?

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

LOL, knew I opened up a can-o-worms. 

There are of course several ways to do this.....

Using RCA cables, they make filters that attach right to the end of the cable, then go into the amp. 

They also make ones that go on the speakers these would go in series with the speaker cable, through the XO, then out to the speakers.

For both options you would need 2 pieces of each. Both are about the same price, with their own pro/con 

Yes, you would want a hi-pass filter for the mains, and a low-pass for the subs. Sorry for the confusion 

high-pass

Hi-pass RCA

here is some info so you can better understand....

@mswale - that ’speaker’ filter does not specify power rating. Judging from the picture it would only work with few watts amp. '250 W RMS', well, we've all seen boomboxes with '1000 Watts' stickers...

@mswale so the High-pass RCA link is the simplest, it's a plug that has the filter inside? All the signal that comes out of it is above 100Hz? Reading the reviews, it's simple and effective.
