May be a stupid question but I have a genesis g-928 sub. For those of you unfamiliar with this sub it is a 2cu ft box with the amp on the back, it has 2 12" drivers, one on the left, one on the right. It had a busted amp. I have replaced the amp with a Dayton 500w plate amp and wired the subs up. One thing I did not pay much attention to was the wiring they had on the subs originally, I just unsoldered them and resoldered the new wires in place (it had 2 4ohm dvc subs wired down to a 2ohm load) I wired series-parallel to a 4ohm total load. Anyway, enough of what I've done and more to my questions. If you have 2 subs, sharing the same box facing opposite directions, but in the same phase won't they cancel? Do I need to wire one of them 180 out? I hooked it up and it does sound absolutely amazing. Anyway, if I need to wire 1 sub 180 out of phase how the heck would I do it with my current series-parallel wiring setup?
