Re: How much to pay...? (Guvs97JettaGT)
I looked and asked around. A typical amp install cost is about $50-75 plus whatever wiring. It really shouldn't take over an hours labor to install one amp I think.
As for the sub, is it a regular box that has the box inside and is wired? If so, you can just sit it in your trunk. Connect the speaker wires from the amp to it - you shouldn't have to pay them for that.
