Hello All.
Ok.. I've had car audio in my car for about 10 years now..(not the same kind all this time!)

I'd like to learn how to install my own HU and amps. This weekend with my friend I'm going to attempt to run an amp.
I plan to install a 4 channel amp to have 2 channels going to the front speakers and bridging two channels to power a sub.
My Questions are below.
1. Where is the firewall hole in a 6th gen accord sedan?
2. I know power and rca's get run through different sides of the car, but in order to power front speakers, do I need to run speaker wire? How do I amp the front speakers I guess is my question?
3. how do I bridge the two channels of my amp? Is this amp specific? If so, I can provide pics and details.
4. Any suggestions on where to ground the amp in the back of a 6th gen accord?
Thanks guys! Also, if anyone is near Edison,New Jersey and wants to hook me up with an install on Saturday, lunch is on me!
