Car Amplifier Instalation
 

Hello I'm new to the forum. I have a 2007 Chevy Monte Carlo SS, I'm installing two 12" Kicker L7's in a ported box with a 1500watt kicker amp. Just seeing if anybody had any suggestions on where to ground the wires for the Amp and Capacitor. Where are 2 good grounding spots? Right now I have one wire grounded to the first bolt on the right wheel well where the XM Module is and the second wire I have on the first bolt where the Onstar Module is on the left wheel well. Also I am going to do the Big three upgrade. Any suggestions where to make my ground In the engine compartment? And how to u get to the negative terminal on the alternator? And if anyone has any tips on how to get the power wire thru the grommet on the passenger side to the battery? Any helpful suggestions would be appreciated! thank you!
