yeah guys, i pretty much sold both my subs, got a shok triton 15" and built an enclosure that has 3.7 net cubs tuned at 30 hz, a little bit off from the recommended spec but its hitting waaaay harder than both my old 12s combined with better sound quality, a lot less punch due to the tuning though, but who needs punch in your bass when your car is falling apart and heads are split open ""(@_@)"".
I also bought a high output alt for 169$ (friggen steal!!! got it from more_amps
ebay seller, lots of cheap rebuilt japanese vehicle brand alternators with warranty) tested it and i got 160 amps going now, 0 gauged everything with knukoncepts kolossus and now i have a kinetic hc 1800 comming from Sisson16 and i'm going to hook that up as a 2nd battery (gonna be the only corolla in my city with 14+ volts with a loud and stable system if it all works out lol).
Man the triton rated 500 rms but its taking over 950 rms easy at 2ohms, hasn't gotten close to bottoming out. i'm also on the edge of pulling the trigger on an american bass VFL 4480.1D from mylows10 but i'm not sure if those shoks can handle the ABs but on the other hand, that would give me a future reason to buy a stronger 15" which would have me continue the downspiral of basshead poverty @_@.
PS: I haven't seen too much of the shok industries subs on youtube, i'll post a vid once the sub's fully broken in maybe you guys can see if it can handle more power than i'm currently giving it.
moral of story i learned, shoddy mainstream subs/setup
Thank you all for the help and suggestions, they are working wonders.
