My Bass no Boom???

[sort_o_sane]

The LOC i have has a total of 8 inputs, 1 for each of the main cabin speakers. What i haven't been able to loo up yet is the original manual for the LOC. I cannot recall if the inputs for the front will only run back out through the outputs for the front channels. The only reason i would be try crossing signals is because of not knowing this. I might just take pics and show everyone.

My setup consists of a sony explode 1200 watt amp and 2 Alpine 12" type Es. All wire is quality and thicker gauge. All connections are tight, soldered where needed, and secured.

The original subs i had were dual BP MTX subs that were 4 ohm and i had them running in series, but thought i was bridging into 4 ohm when i was bridging 2, and blew those subs. Found the Type Es on a great holiday sale last Christmas.
I'm running parallel with the 2 subs in their own boxes.
