Im looking to get one 12" CVR, 400 RMS, 800 peak. I am not looking for a crapload of bass, so one will do just fine. If I get a kicker amp pushing 400 RMS, my question is, am i going to be able to power all of that with my stock alternator? Im not really looking into getting a new alternator... I drive a 97 corolla (gotta love it!) and i think it has either a 70 or 80 amp alternator. So if i have the 400 rms for the sub and the 65 rms x 4, do you think i will be fine? I dont see myself pushing to full power at all ever, because i like my hearing. Will getting a cap help? Thanks for the help! |

Take a mulitmeter and test your battery to see if it is dropping below 12 volts. If it stays consistent you should be ok... |

I ran 1100w in an '88 Tbird with a 75A alt, and I DID blast it fairly regularly and I DO listen to bass heavy stuff once in a while. It wasn't ideal, but it ran for 2 yrs before the alt finally gave up. It was the original alt and had 226k on it. |
