alternator and amp question

[Mongojerry36 10+ year member]

I have a 2001 toyota avalon and the stock alternator is 80 amps and I currently have a kicker 1000w amp in the trunk powering two subs. If I got another amp around 200w and a headunit to supply 4 speakers would that be too much strain on the alternator??

im suprised you can run that 1k amp with a 80amp alty, id pick up a second batt for the back

it should be okay, i have a 2003 civic with a 60-70 amp alt. and i'm running a big fat battery in the back. i have a little over 2K watts being used and i've had this set up for over a year and my car still runs fine.

But i'm with clickclack, get a second batt. you'll need it for anything 1K or over.

i also have a toyota celica, with the stock alt 80 amps and power master 1200 under the hood with big 3 done on 2000 wrms and lights never dim etc you'll be fine just get a nice battery under the hood with big 3 done.

alright so the alternator would be able to power the two batteries without any problems with dimming lights etc? i dont have problems now suprisingly
