I have no idea about car audio, only home! I am trying to hook up a sub for my daughter's Nissan Altima Coupe. I bought a Polk DXi1201 sub and enclusure. I also bought a PA 330.2 amp. Both clearenced cheap at Best Buy. She has a Sony DVD head unit with a sub out.

First, can I use the amp bridged to power the sub?
Second, Best Buy wants $150.00 for the amp kit. I am willing to pay the $100.00 install fee, but the kit seems way
over priced. Can you suggest a cheaper amp kit?

Thanks, Jeff
