i got a civic and i am pullin 2 subs that are 800 watt max and a 400 watt component set . Which is better to use for the sound system, a seperate battery or a cap??? And can u tell the differnences between both of them????

 

i have both but it depends on if you need them or not. if your amp is drawing too much current, get a cap first, its cheaper and see if that solves the problem. if your lights still dim then its still drawing too much current so get the battery. thats what i did and was told.

 

A second battery will do nothing to help your dimming solution, and it may actually make it worse. Use a second battery only if you plan on listening it to extended periods with the car off.

What's happening, is your alternator can't produce enough juice to support your amps. I would consider upgrading the underhood wiring, then try a cap. They are a bandaid, but my help in your situation.

 

Hey,
Thanks for the advise man. What is the best cap out there to use for my civic? And which farad should i get?

 

400 watt components???

dear god, focal and infinity push 200watt, which components do you have??

if they are actually 400w clean, then your gonna nead a 1 farad cap and prob an alternator upgrade to push the system.

pretty much all caps are the same because there are only a few companies that actually make them so as long as its a name brand you will be ok.
