great unit!! :)

February 8, 2012

This units is great!! I highly recomend it. I use to have a lightning audio amp and stereo with it and it power it with no problems at all, but now that i got my gm-5300t pioneer amp i use a battery to power the system. Even with the 12 volt battery works great!! :D I highly recomend this power supply.

Bigger Than PS12

July 6, 2010

I got this model because the PS12KX were clipping on me when I ran a 1M Candlepower spotlight off it. This unit is bigger and will not clip. I wish they made this with a cigarette lighter plug, but maybe they can't with this size.
