Stereo & Electronics - Need an adapter for factory head unit

I know this isn't for an f-body well not yet any how, but i've got a bangin system i just pulled out of my blazer because i plan to get rid of it. My girlfreind has a 96 dodge avenger and she wants to keep her factory head unit. Its the full infinity sound system and she likes it but she wants more bump :D I know my system is all ready to go but i need to know where i can get a speaker adapter so i can have the amp outs. i think scosche makes one i seen it in a summit catalog part number SCO-LOC80. Is this what i need or somethign else? thanks

are you just talking about a standard line-level adapter?

as long as we are talking about standard speaker level outs from the HU, converter will work fine -- they are NOT vehicle specific

your gf's being a full infinity system might be different though..

EDIT: meant to say NOT vehicle specific

sorry totally read it wrong the first time just put in a LOC behind the radio and run your rca's to that. You want to splice in at the radio since it will be a cleaner signal then after the infinity amp

yea thats what i was thinking so would the adapter i have above work for what i want. i just want to put subs in a car with a factory head unit.

I have an adapter like that, if you want to wait for shipping I could ship it to you. I dont want anything for it you can take it off my hands. I had two 12s and not enough money for a aftermarket hu, so I had to get it but now I have a alpine hu. Just shoot me a pm if you want it.
