Anybody have experience with this product? Just wondering if it'll be enough to power a head unit, two amps, and a screen. I'm pretty sure it should, but just wanted to make sure.

 

depends how big of amps you are running. 40a can go by quickly if you are trying to power a pair of big class AB amps.

 

Kicker ZX650.4 and ZX1500.1 ... won't be turning it up full blast all the time, but it will be running at moderate levels.

 

kinda small man i would look for something a little bigger

 

ya you'd def want more headroom on those amps. basically just add up the fuse values and get one that supports that many amps.

A little over kill but will give you the headroom you want without killing the power supply.

 

tested it last night...works fine, but haven't turned it up REAL loud.
