I just installed a system in a friends 05 Avalanche with factory navigation and you cant even tell theres a system. Someone please tell me what's wrong! Heres the setup:
PAC rca converter
(2) JL 12w6v2
Directed 1100d
Factory navigation
running at 1 ohm.

I didn't think the avalanche had the fixed output bose system, but if so you'd have to grab your signal after the amp. Also are you sure your subs aren't out of phase it would cause the same issue.

do the subs move at all? does the amp power up? where did you get your remote turn on?

Yes, I also moved the converter behind the factory amp and still didn't solve the problem!!!!

You moved the LOC behind the amp? So the vehicle has the BOSE system. Did you tie the LOC into the factory subwoofer leads, or the rear speakers? You need to tie into the subwoofer leads to get any low frequencies. The rear speakers have a bandpass crossover, they only play midrange frequencies.
