Question

I bought this Subwoofer Package online and it brings a 600 watt amp 500 RMS and i have a 1988 Dodge Dynasty 3.0 L and it has a 120 AMP Alternator is this big anough to run my amp and all the other stuff in it?

Answer 1

Do not worry,your alt is big enough.

Answer 2

With an 80% efficient amp, you're good to 1250 watts RMS.

(((total RMS power X (1/amp efficiency))/car voltage @ 1500 RPM) X 0.637) + 40% of your current alternator

Answer 3

yeah you are fine just get a cap if you are worried

Answer 4

Yes you should be fine. I have a Dodge Durango with the same altenator and i'm running 3 times the power with no headlight dim or any other problems.

Answer 5

you are far from needing an upgrade
