Yeah yeah, another idiot that doesn't know jack about his BOSE.

Here's my situation,

I have all my BOSE speakers still in, with an aftermarket deck installed. The aftermarket deck only has 2 preamps which are both being used by the adapter to make the deck work (or maybe one is for the adapter and one is for the antenna adapter? hell if i know. I just know they're being used.)

I don't want to replace all the speakers. I'd like to keep them.

So I was wondering if by some miracle there is a way to add Subs on without getting another deck with 3 preamps. This might be a dumb question, probably is, but I'm trying anyways. I remember reading somewhere about tapping into the back speakers, which is ghetto yeah, but I don't really care. I'll do it.

 

You need signal, you can use the speaker outs of the HU to a line level converter and get signal to a sub amp that way.

 

there pretty cheap and very easy to install. take the 2 pos leads and splice it to one of the pos speaker leads, then take the 2 neg leads and splice to the speaker neg. i ran my car like this for a couple years works great!
