hello. i have a 1993 Toyota Camry LE. i have an Alpine headunit. Infinity and Alpine speakers. a Kenwood monoblock amp powering a 12" Alpine Type R. my lights dim when the my music hits heavy bass notes, especially my headlights. currently i have a ordinary Duralast battery that i bought from Autozone, its pretty much brand new. i dont usually play my music loud while the car isn't running. what can i do to get rid of this dimming? thanks for your time.

It will run flat in no time, and you will be replcing that battery at least once a year. Trouble is that the stock alternator even after a big-3 upgrade will not sustain enough current to properly charge an Optima deep cell properly. As others said, get into doing your big three upgrade FIRST, allow the alt you have to breathe and push current to your standard lead-acid cell battery. IF and WHEN it is not sufficient enough, adding batteries will not be your salvation - upgrade alternators will be. To push your sound system to peak performance AND keep your battery topped off properly, you need *CURRENT*. Adding an AGM/Deep cell battery increases current demand and looses you vital power needed to run your accessory load and keep the cells charged. Do the big three as other said, make sure that you have *solid* grounds,add more parallel pathways with plain old 2ga heavy duty battery cable with star washers where in doubt and add a cable with a lug from alt to battery + post - you'll be surprised what it can do.

to tell you the truth. i dont now squat about engines and what under my hood X] lol. how do i know if my alternator is good? and what kind o battery i should get regarding in getting a 2nd one.

i dont know how to do the big three. can you please tell me the specific items i need to buy for the big 3. or do you think i should take it to a local audio shop.

Incoming FAQ drop! What is a Big Three Upgrade? Do pay attention to the vital first page. The rest is a running Q/A session that may also help, but page one is the dirt. By all means, if you do not trust your abilities, get it to a shop. Better to be safe than sorry after being confused. :DLife is too short to build slow computers or weak audio!
