How much wire ?
I was wondering how long of a wire i would need to run to my amp..... its going to be in the trunk.
how long do you guys think it needs to be to run it through all the panels and under carpet ?

no problem....just get the right gauge wire, make sure all your wires connections are secure & your good to go.

If he plans running 100 watts or less, 8 will cut it.
I always run 4 as a minimum. And my sub leads are 8 guage.
And, just because your amp says 600 watts(or whatever) does not mean it could ever push that much.
Voltage X amps = watts
So say your amp says 600 watts, and it has a 25 amp fuse.. At 14.4 volts, the most it could ever produce is 360 watts.
Like my amp specs are 800x1@1ohm. It has 3-30amp fuses. So it actually could be capable of a 1300 watt peak. Very few amps are efficient enough to come close to their potential though.

also i have an active crossover, will i need to run another power line or can i just run it off the same power wire as my amp?
thanks for the help guys.... i guess i need to learn a little more before i go blowing my stuff up
the sad part is i went to school for electronics and i never learned anything about car audio

yes....usually crossovers have your RCA inputs & 3 wires...power, ground, signal....easiest way would be....
... signal can be inserted in the amp remote wire terminal w/ the remote turn on lead from your head unit, the power can be ran in the battery amp terminal & u can ground it where the amp is or anywhere else u find bare metal.Last edited by koda.Z28; 01-06-2010 at 10:52 PM.

Also, if possible, ground to the same point. It will alleviate the possibility of a ground loop.

Did you mean different points? I would ground (common) all components seperatley. That helps against a ground loop, especially in higher power systems, this partially why you don't bother running it all the way back to the battery. Also quickens troubelshooting and makes hooking things up easier because you can ground things in a shorter distance.
I have seen some people who have done this and after hooking too many things up to one point, the ground no longer worked for the addition of another component.
