Thread: question about hooking subs up 99 grand prix gt.

No. But they make some amps that have a thing that you splice to the factory speakers wires and it plugs into the amp, this isn't the best way of doing it but if you have a factory deck its the only way to really doing it that I remember.

Thats a high level input. You'd want to go with a LOC and some RCA's if you plan on keeping the stock deck for a while. But it's gonna sound like chit if you're looking for any kind of sound quality. The bass is gonna sound loud at low volumes and weak at high volumes. It'd be best to go with an aftermarket deck so you can control the subs separately.
