I am initially connecting my amp. I have everything hooked exactly as the book says. Ground to battery, all speakers hooked up and phased correct. Lead from antenna power to amp. RCA cables coming out of head unit (Kenwood 248).and plugged up. When I connect the power lead to the battery, I got a big spark and the amp does nothing. I did not hear a popping noise other than the spark. Help?

Very possible that you have a blown power supply in the amp. If you are running a mono amp then there is a very good chance that you have loaded your amp with too low of a speaker impedence and fried the power supply and maybe the output section of the audio area. Hope this helps.

You'll use fig.8 for the front speakers and fig.9 for the subs.

You need to check the Fuse on the Power Wire and check the ground wire to see if has loosened up. Also check Power Wire as well.
Hope you see what you are your looking for! Good Luck!

Sounds to me like it might be the remote turn on because the first time i installed it, it did the same thing, and i found out that there is two blue wires coming out the stereo, one with a white stripe, i connected it to the blue wire, and it didnt work, then i connected it to the blue and white wire, and it worked. Well hope this solves your problem, goodluck.
