That shouldn't be too much on a stock alternator. You may have another problem. You can get a high output alternator from www.4alterstart.com, but I don't think this will fix your trouble in this case.

what size power cable are you running to your amps? you need to reciprocate it on the ground side of the battery to allow the electrical current back to the battery. replace both side post battery terminals (positive and ground) with aftermarket accessory battery posts. Hook your power cable to positive and take the same size wire from your ground to the body of the car. this increases the ground wire capacity to allow correct flow back to battery. this will help if your lights dim and will extend the life of the alternator. go buy a cheap one at autozone after you correct your wiring and try it. if that one fries too, lifetime warranty baby! but seriously, the draw you have from your amps can't return to the battery through your factory body ground, so you have to reinforce it.

I tell it like it is...

I been down this road before. I worked at a shop that rebuilt Starters, Alt, and electrical systems.

Do your self a favor and skip the rebuilds at auto stores, There cheap junk! Go get you some factory parts. Rectifier, Stator, and windings along with some needle bearings. Then rebuild it yourself its not hard. Also dont buy cheap batteries that use cheater blocks to fill the case. There black so you can't see the plates only go halfway down.

NP, I still don't know why people use a Capacitor. They do nothing but drain your battery and steal energy. It has to be charged by your alt to start with, When it discharges your alt now has to charge the cap and run the system which taxs the system even more. iIt may look cool but the money could be spent on a real good Alt or battery to start with.

If your battery, Alt and wiring are in good shape you don't need one to start with. They are used to try and fix a problem with the electrcial system that needs a upgrade, You can't fix it with a bandaid.
