I just installed a Rockford Fosgate Punch P8002 amp and 4 gauge wire kit. The amp wiring kit came with only a 80A fuse but the Punch amp recommends a 150-amp fuse. Can I run the current fuse without worries?

I agree with mat. To add to that - if you're not running the amp bridged or with both channels at 2 ohms that fuse will probably never blow. Even if it is running like that you'd have to be driving it awfully hard to pull more than 80A rms.

And FWIW - 150A is on the high side for 4 ga. At 15' 4 ga is rated for up to 130A.

that or youll clip your amp because it cant get enough power through the little fuse, which is bad, i would spend 25$ and get a 150

Its only like 10$ for the fuse, you limiting the power to your amp if you got your settings high it would make it distort with littler power then needed...yadayadayda....... get the bigger fuse it will prolly sound better depending on what your pulling now.

A fuse doesn't limit power, it just blows at a certain amount of power, usually over time, as protection against damage and possibly a fire from excessive power.
I would use the specified fuse rating, they engineered it and put that size fuse in it for a reason.

The amp has 3*40A fuses=120 and the battery inline fuse is 80A. But yea, sounds good, I'll just replace it if it blows. Thanks for the help.
