I have the full premo sound in the Ghia with the factory sub and speakers they WERE sh*t. I replaced it with over 1500 dollars worth of gear. Sound Stream speakers, custom wiring (done by me) amp comes on with ICC no matter if the key is in. 400W Clarion Monoblock amp. She pumps now. but the so called premium sound aint so premium. He is doing it for the colour screen and six stacker.
