Mono amp acting up?

Hey guys, got a wierd problem with my sub amp.

Not running anything wierd here... just a mono amp to two 12"s...

I pulled my entire system out yesterday for a rewire... and strange stuff happens now. I'm not sure why. I connected my RCAs to the amp, and turned it on... the sound seems crackled and "flat". I can't really describe it any better but something seems wrong. When I pull out the red half of the RCA cable, boom, back to normal... well. Only one speaker hits, but it hits normally.

What the hell happened? I checked fuses and they're fine... should I replace the speaker wire? could that cause this? Is it my amp? The speaker itself? Where do I start?

Take one speaker wire (doesnt matter which one, but just one), flip it around (pos to neg, neg to pos). It sounds like they are out of phase with one another, whether it be in the box or at the amp hookups. Is your box divided in the center or do they share the same airspace. Just curious more than anything. Lemme know...

The box encloses both subs, and is ported in the middle, so they are sharing the same airspace.

Try swapping one woofer's wire like I mentioned and see what happens, I think that'll take care of it...
