I have the bose system in my 0t5gmc ext cab and i want to add my atlpine amp and type E 12's i have no idea where to start any help?

 

when i had my bose system i used a line out converter to convert from speaker level to rca level. i tapped the wires that feed the bose sub for the outputs and ran the rca's back to the amp, i just got a pre fabbed box from a local shop and dropped in 2 10's, sounded damn good to me.

it has been a long time since then but i remember i pulled the cupholder out of the console and the bundle of wires that was under there has them in it, i just squeezed on some t-taps, it was a tight squeeze but i did it without having to take anything else out. i ran the rca's under the carpet straight back.

 

i did the same thing
i know you can either get the pac converter that you plug into the back of your radio then plug the normal plugs into it and it gives you rca jacks
when i looked into this last year it was like $70 or somthing

or you can get the universal pac converter that has 2 wires that you can t into your stock sub wiring. i htink it was like $10 at the flea market
if you do this in my opinion i would not t into it instead id just unhook the stock sub and wire in the pac converter because once you have subs and amp the center consol sub just raddles and sounds like crap
