If you have 8aeg wire or bigger you are good there.. So the only thing would be that your alternator isn't keeping up with teh current draw from your amp.

hi yeh i am using 8 gauge cables...i guess its ym alternator...this morning the car shut down on me...and the charge light kept coming on..even though my amp was off

Haha, my car had shut down on me once before too. I hadn't put a cap in yet and the current draw was so much that I practically melted the battery. The alternator wasn't supplying enough extra juice thus making the battery work to hard. When I tried to recharge the stupid thing, it just wouldn't. I think I melted the cells! Anyway, yeah, sounds like the alternator... could be something grounding out and causing a short in the system. Check all of your connections and go from there. Peace.

hey StallionAudio

well the charge light comes on lets about 5 minutes after i put on my amp...even after i take it off...the light still comes on...i read about some people that get there alternator rewound....would that make a difference ?..would it help ?

my battery is new but i think my alternator has a good few years on it

thanks

The charge light is staying on even after you turn your amp off b/c the battery's power is still too low... it sounds like your alternator is really struggling... the battery is supplyin most of the power, so it gets drained quicker. Yeah I have heard of people rewinding their alternators, I had to have the brushes cleaned on an old one of mine. You can try this and it may work. I'm sure if the mechanic looks at it and thinks that it isnt even worth doin or it is gonna be as much as a new one then I would just get a new one. I dont know what kind of car you have, but for domestic cars they arent all that expensive. I dont think that you would need a high output one for just that amp. You may want to look into buying a capacitor as well after you get the new alternator. This will help prevent the situation from happening again. Plus you'll get better performance from the amp with a cap. So you have a couple of options here. Good luck with that stuff guy. Peace.

hi StallionAudio

thanks again....i have a mazda 626....its pretty old....i think the alternator was serviced a few times..i'll have to check with my ole man...the charge light comes on for about 2 secs...then goes off...then starts to flicker....i plan later on when i get some cash to add another amp and a sub...so whats the best way i should go ?

I dont know how youd go about getting the car reset but if the charge light annoys you now wait till you put a bigger alt in there..It will come on for both over and under charging...//content.invisioncic.com/y282845/emoticons/banghead.gif.8606515f668c74f6de0281deb475b6fd.gif//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

A lot of SPL types end up disconnecting the light because of this.

Like Mike said the light will come on for over and under powering, that is the whole point of an electrical indicator light... your problem sounds like underpowered. I would go with just a new alternator... especially if your gonna be expanding. Might as well do it right. Again like Mike said you may want to go with disconnecting the light if it still acts up... at least once you put in a new alternator it wont be the underpowering causing it... it'll be b/c you'll have enough juice. The little things can be the most annoying, haha . Take it easy.
