A cap is always a good idea. it helps with power requirements that is needed from amplifiers when it is needed. The higher the rating the better holding of power. They work best right by the amplifiers.

Can you run a 8 gauge power wire to a jl audio 1000/1 amp and not have problems even though jl reccommends 4 gauge power wire?


Hi, if you're going to run a smaller wire, you also need to use a smaller fuse. A 50 amp fuse is needed for 8 gage wire. The fuse is there to keep the wire insulation from melting, which is what will happen if you run too much power thru the wire. If you don't plan to turn the amp up too high, this may work fine, but I would test it first with a 50 amp fuse before installing. You will need all of the speakers hooked up and the gain set to max to test the power draw. See the following link on wire sizing for more info: http://www.bcae1.com/wire.htm

I have a jl 500/1 pops fuses some times could it be im pulling too much power from the battery because i dont have a cap or extra battery im running at 2ohm with a 15 inch kicker l5


Seems like the KICKER is pulling to much power try to knock it back up to 4ohm and see what happens. If its fine that way then you might need a bigger amp.

I enhance volume car light shimmer and amp off.


Need more info. Are you sying that your lights pulse to the bass? Capacitors help. I would recomend at LEAST a 2 farad. Make sure you are using GOOD QUALITY 4 gauge power wire. So many "kits" say 4 gauge, but strip it back and you have a glorified 8 guage wire. I've seenit. Also, MAKE SURE that it is ran to the bayttery and use the SAME gauge for the ground (no more that 4 feet if possible).

In case your next question is "how do I hook up a Cap?", here it goes:

Power AND ground to the cap, then power AND ground from cap to the amp input. So very easy!!

Added another amp to system now subs dont hit as hard


This sounds odd, but try putting your subs out of phase from the mains. Just see if it changes anything.

Blowing fuses


You will need to have the amp bench tested at full load to see if there is a pending problem. It will need to see with speaker loading resistors, how much current the amp is drawing and at different frequencies. if the amp checks out with the proper current, at the rated output, have the speaker checked out. Good Luck
