Not a solution.

I bought one of these LOCs, gave me a lot of engine noise, and when I grounded it, it just became worse, the ground cable wont work as it should, it looks great, but it wont solve your problems.

Nice, but should have gotten the LP7-4.

This LOC is very nicely sized and easy to install and use. It fits in the dash behind the H.U. nice and neatly. The only thing I would have done differently was spent a little more money and gotten the LP7-4 with the amp turn-on wire. Because trying to find an aux. power for the amps in a 2020 Camry is not very easy or fun!
