ok this started a month ago, my right hand sub blew, i chocked it up to a year of abuse and so forth, so i reconed it, dropped it in, and blew it in seconds,.... i thought maybe i miss shimmed it. well i barrowed a pair of BTLS from a good friend, and same mother fucking thing, every time on the right hand side sub. i checked all my speaker wires, and termials i check how i had it seriesed, i did find what seemed to be an issue of 1 RCA seemed to cut off when i jiggled it, but even if its shorting out, its feeding a mono block amp.... so it would short BOTH subs.. not just the right hand. im really at my end and im not sure what else it could be.... i cant continue to keep blowing expensive subs trying to find my issue. and its killing me installing and pulling everything back out. out side of the box, inside nothing touching... WTF?
