oh man, first timer for car audio install. alright follow along. On driver side FAR UP the dash, there is a large black grommet that u can run your power wire through. Run your power cable along the panels that hold ur carpet in place (trim @ door) run wires all the way back to ur trunk for your amp. Now from your head unit, run a remote TURN ON LEAD (usaully blue with white stripe) and run that with a set of RCA cables to the back OPPOSITE SIDE OF YOUR POWER WIRE !!! now as for a ground, Use an existing bolt or make ur own hole to screw down a ground cable. Make sure the grounding are is clean of paint or any residue. A best ground shows 0ohms on a volt meter. Make ur necessary connections. Now, depending on ur amp, it really depends how many ohms it can take. if its a 2 channel to bridge, Connect the Postive of Channel 1, and Negative on channel 2. Some amps will use 2 postives on each channel. Double check with ur spec sheet. As for fusing the 12volt wire, Measure 5 inches from the amp cable from the batter, Fuse it accordingly, and your set. Enjoy some music.
