PAC PAC-200

amazing

This is the best thing I have gotten for my system in a while its easy to install takes no time at all and makes a huge difference I would highly recommend this

very helpful

This works like a charm. I us it to connect my backup battery system when i need it. Works great. Never had a problem. very simple to hook up and mount.

great product!

I've had it in my truck for over a year isolating from the factory wet cell
and a Kenetics HC2000 AGM without any problems!

PAC 200

I have bought one of these for my US AMPS vlx-400....i never got around to hooking up the amp but these isolators are awesome...they are the same as the stinger ones but u pay half the price....very nice features on it as well.

Great Value!

This product is a must for for isolating (2) batteries for todays high power car audio systems!

works great! a must have is you have a big system

Works great no more dimming lights and worries of battery draining.

Battery isolator

This isolator is a must need and use item for running an auxillary battery. I don't have the problem of a no start when I play the stereo for hours on end. When I do start the car up both main and aux battery are charged, but I would recommend upgrading your alternator and wiring to fully appreciate this. All my equipment gets full voltage,even when I try to deafen the neighborhood. Great price from Sonic too.

Works flawless

No problems to report. Great value, I recommend this. It's been in my car for 6 months now.

Excellent Product!

This product works exactly as it should, easy install and wiring and it accepts 0 gauge ring terminals without interfering with the nearby remote turn-on and ground wires.
Best relay out there, stone cold reliable and inexpensive.

Pac-300

Wanted another battery in my truck for my winch and audio system. I would reccomend this to anyone who needs another battery. Easiest way to install the accessory is with a rocker switch. I have had this isolator for six months now with no problems. Nice to have double the cranking power in the winter. :)
