I am installing a 1000w rms amp with a 3000w max output, along with a subwoofer with the same specs, into my 2003 alero. My alternator puts out 105 amps. I am concerned that the amp is going to put too much strain on my system and start shutting down electrical components around my car. Is this a valid concern and if so, what can I do to support the new amp and sub? Thanks.

yes, it could make your lights dim. but if it does just add a HO alt from excessive amperage later...
