I just bought a Dual amp and Sub combo with illuminite from best buy my friend and i have installed everything in my lexus sc400 with the nakamichi sound system. We got the lighting to work in the sub box and the amp works fine but i dont have any sound from my new subs. i still have the old subs in there working every other speaker woks except these new subs. why am i not hearing sound? i also bought a line out converter from circuit city it has 2 Right wire and 2 Left wire and converts into RCA. my friend said that i didnt have to use the Left wires so he connected the Right positive and negative only. is there something i can do to get the sound from my amp to the subwoofer? there is one positve and one negative audio input terminal on the sub box itself i put the speaker wire thats connected to the positive and negative bridged ports on the amp into this. Someone please help.

are you running 1 sub or 2?

i have the fasctory amp and sub. but i am only running this sub box off of the amp. could it be a problem with my line out converter or my RCA cables?

Ok here is what i think your problem is,your line out converter id set to run 2 subs correct.What you gotta do because you are only running 1 sub is tie both -,& both+ wires togeather on the line out converter,this will change the converter to run on mono.IMO running the factory sub,& the aftermarket sub in the small trunk space will not sound right.1 or the other.

there are 4 speaker wires on my line out converter to convert it to RCA which do i connect with what on the head unit because im totally lost, and the wiring diagram on technicalhelp4u isnt helping now because its not color coded and i dont really know what that stuff means. somebody tell me exactly what number plugs, in what harness i should connect the 2 left wires and two right wires to. Thanks in advance.

What wires in the stock amp could i use to connect the line out converter to, if its possible?

If I were you, I would connect the LOC to both of your rear speakers. Just to make sure you have all the bass from both signals. It may not make a difference but it sure wouldn't hurt. Then connect to your amp and make sure your gains are set properly with a DMM. Also make sure the amp is not in protected mode. I guess the last thing you can check is your wiring. Make sure you have it well grounded.
