i installed my subs in my 01 cl-s using a hi-low converter. it was working fine at first but after we finished up connecting/taping all the speaker wires and messing with the frequencies and such, the sub seemed to have lost signal. we could not figure out what the problem is. here's what we did for the installation: we connected the hi-low converter to both the rear speakers, then using rca cables connected the converter to the amp and the amp to the battery and for the power switch we just connected it to my rear light. we grounded the the amp and everything. it worked at first, but it isn't working anymore, i'm still getting power to the amp but the subs arent working.

any ideas? thanks.

 

Let me suggest to scrap the HIGH-LOW converter and use the direct line outs from the factory deck to the amp. I did that and despite what was posted earlier about the signal not being strong enough I am getting a great signal and my amp is only a Mono block 500W bazooka. Go and check out the post on the wiring diagrams for our stock decks and take your trunk apart and tap into the leads to the rear speakers. It works GREAT!
