I ran 800-1000 watts on a 90 amp alt. Car quest battery under the hood and yellow top D31A in the trunk and 1/0 gauge power and ground.If he has a car built in the last 20 yrs...Probably.
You wouldn't be able to crank out 0db test tones at stated 14v power, but a 1000-1500w system will perform just fine playing music on an average stock electrical system.
Although a burnt up alt every couple years can be expected.
I burnt up my alternator in 1 year. Bought it brand new. 1 year later it was putting out 12.9volts.
