Can i do it? Am i able to add an after market sub and amp to my stereo and keep my stock head unit? I really dont feel like replacing the whole thing..

 

Alright i answerd my own question now with this line out converter will my speakers still work as the did b4?

 

yeah, they'll be ok. just make sure you add the line out after the factory amp, cuz the head unit isn't supplying any power. if you have a vert, take out the back seats and you'll be able to get to the amps from there. If its a hardtop, then they're in the trunk.
