I have a 13.5" Jl w7, 1000/1 JL amp, and a 10 farad cap. My voltage fluctuates and when bass hits hard it gets down to 8-9 volts and amp shuts off. Obviously the alternator can not keep up with the amp's need for power. What should i do, get a H.O. alternator or a BatCAP. Where can i get a HO alternator and/or what Batcap would i need?

bobbyt-yea I wouldn't think a 1000w amp would cause issues but this JL 1000/1 is known for sucking up serious power, not so efficient as other class D amps
acuteperformance- I was reading up on BatCaps and it seems like that might do the trick, not sure though. Which one should i get for my system, 300,400,800?

From my experience and knowledge about car stereo
i would replace any alternators, only thing i would do though is get bigger cap if not enough then get another one.
that should fix the problem. after all thats what the caps are for
hope this helps

are you running a good name brand cap? some of the cheaper ones claim 10 farad but never store that kind of power.
i have a 5 farad alumapro which are the best caps out. i used to run my orion 1200D monoblock at 80% throttle at 2 ohms (about 725watts) on my previous car and i never had any issues which dimming lights or voltage.

i think im going to buy the alumapro 5 farad cap, where can i get it for a decent price?
check your setup and find out how your equipment is installed, im driving 1000 watts with no problem and my Hertz Sub hits super hard
