Alright. Heck, for $1000 total, we could help pick out the complete package, save CD changer.
The install question was namely to find out if you could do it as it will allow us to recommend some not so name brand equipment that is mail order only, but excellent quality.
You live in Plymouth? I'd be willing to help you out with the install if you need it to save time.
Dnewma04 listed excellent subs. All of which could have the potential to be more than what most people need.
Get the harness like Crazy Chicken said.
Components speakers are a little bit more work (I installed a pair in about an hour) but sound excellent.
Ubid is great, but the supply has been low lately. There can be some deals on the Scratch and dent page at
www.partsexpress.com as well as maybe a Deal of the Day offer.
