power cap or additional battery????

[ClarkX3_213]

Im planning on purchasing some new subs eventually and the amp im looking at is 4000 watts (lanzar MXA282)... im not sure how it will perform in my car i own a 91 mustang lx and as far as i kno the stock alternator generates about 75 amps... i was wondering what would be the best way to go (since im kind of on a small budget) with a power cap or seperate batterys or do i even need them at all...? I've seen batterys that claim they can do the work of 200 1 farad power caps would this be the best way to go or should i just purchase a 5.0 farad power cap? any info would be great thanks!

Not familiar with the amp but if it's really 4000w you're going to need to do a hell of a lot more to your electrical than just get a new bat or cap.

You need a new alternator for 4000 watts my man.

I'd get 40 powercaps //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

dude... hhaha

dont get caps.. they do absolutely nothing for ur system.. if anything get more batteries... but u are going to need to get a bigger alternator and do the big 3 with 4000 watts RMS!!!!!!!!!!

**** that, use plutonium.

Plutonium=1,000 caps

jp man, ditch the caps and get your alt rewound and pick up at least 2 batts, but I doubt that your amp is really 4k watts. Maybe closer to 1k realistically

You deff need a bigger alt. my bro.

DUDE! on your eletrical you are not going to be able to see more than 2k and that amp cannot take any less than a 2 ohm load. ..i doubt youll see more than 1500 if not less than 1k of rms from that amp. just get Better batteries and big 3 YOU ARE GOOD!

That amp = noob buy.

Your electrical system = Not enough to push more than 1K watts.

Your solution = Big 3 upgrade, rewind alt or buy a HO alt, plus upgrade your stock battery.

Slow the fawk down.

That's a 900w rms amp. The average alt shouldn't have a lot of troule.

that amp wont even do anything close to 4000 watts. It's probably around 800-1000 watts rms.
