I feel like a moron..or I am getting dyslexic now in my late forties.... I can't believe after so many times verifying the polarity on the speakers and the total ohms and looking at the back of the my amp I never seen this...
The problem started last week... when I discovered 2 of the subs were reversed polarity ...but before I got to that I swapped the speakon connectors thinking they were the cause... thats when I needed help fast....so this dummy after replacing the speakons, I created the same problem I solved...by not paying full attention to the banana connectors.
I thank all of you for telling me to keep checking polarity..
Sonnie, my amp is a Crest CPX 2600 ....each pair of subs gets 550 watts at 8 ohms... which I think is adeqaute for an IB.... you think it would be risky if I bridged it to a single 4 ,which would give 2000 watts ..or 500 a piece... since IB 's could be easy overdriven?
