Good product

Seems like a good balance between low price and good quality. Installation was not difficult. It's a little bulky and you have to find room behind your stereo. Instruction manual is helpful. I bought an Atoto a6pf stereo. There was constant static in the speakers. It seemed to be grounded properly. The speakers seemed to be too loud. The LOC that came with the unit made the speakers way to quiet. The scosche slc4 worked much better as an LOC. My vehicle had factory amp and subwoofer. I'm thinking that's why I had problems to begin with. I had another aftermarket stereo in before this one with RCA outputs and it didn't have static. Using the "amp" setting and the "loc" setting on the slc4 seemed to work about the same getting rid of the static. Seemed to get rid of 90% of the static. If I put my ears right up to the speaker I can hear a little bit of static . So I'll call that good enough.

Quality in all aspects of an L0C !!!

Ive never heard of or ever seen this brand or style of LOC..I thought I was sent the wrong one. This wasnt the case at all..I was sent a detailed, sturdy, heavy duty, 4 banger(4 channel) of an L0C that was cheap but not in its Quality..If Im ever gonna need another one of these, this is where its at..Ya'll go get it, you'll see what im talking about

Good Value LOC

This LOC successfully helped me get the alternator whine out of a new head unit (Belva BMV712) installation on a 2007 Pontiac Vibe that came with a factory amp. The buzzing only occurred when the stereo was on and actively playing music, and it goes away when I bypass the amp. It also went away if I turned off the stereo, paused music, turned the volume down to 0, and between songs. I highly recommend this product to anyone with a 2003-2008 Pontiac vibe with the “moon and tunes” or “sun and sound” package, which include a Delphi amp under the front passenger seat and a monsoon subwoofer in the rear right cargo area. My only complaint is that there is no good way to bolt this down to secure it. There are 4 spots where you can insert small zip ties.
