[QUOTE="mendon mafia, post: 6522332, member: 584590"] ok to clarify all the problems i have 2 seperate boxes which i run BOTH at the same time usually. the specs given are for one box. so multiply by 2 and there ya go. My amp is used for both subs. wired down to .5 ohm. (1 ohm when im using 1 sub) problem still happens either using 1 or 2 subs. voltage drop is not a problem i dip into the mid 12's at the lowest. got a 200 amp alt 2 spv70's and a stock batt. only 1 run of 1/0 tho for pos and ground. but as stated before my voltage drop isint that bad. all my filter and eq settings are set correctly. flat on the eq. filter on the hu is set at 80hz, filter on the amp is probably at 70. If i cross down to 50 i will have no output between 50-80 hz, my momo components are nowhere near as loud as my aplhas. and dont really start hitting until about 80-100hz. (I need speaker pods my doors **** for sealing) My speaker wire is 10 gauge and i have separate runs for each woofer directly from the amp. the wire shown was just for testing. Imp rise might be a very likely cause but how do i get around this. never had this problem before. and ive built tons of boxes and systems. non having this large of port area though. but thor and all those other guys with big ports dont have this problem either so idk.
