Great value
It's a great LOC for a 4 channel system which most of the cars use these days.I used it on my car with a factory amp, and that was the main reason to use this as I upgraded the head unit with an aftermarket one. The factory amp just could not digest the hi level input from the aftermarket head unit harness, causing all kinds of static noises.This one got 95% of the buzzing noises. Sometimes I still heard a bit of noise.I returned the unit in the end and went with a 2 of higher quality LOCs which completely removed the buzzing noise.My car is a Honda CRZ which uses a hybrid system, and it's notorious for making static noise compared to non hybrid engine cars.so maybe, this LOC will work for your car if your car is a pure gas car or elec car.

Super versatile, clear instructions, easy to install, loved it, I will buy again
This is awesome, we used it on a 2008 Hyundai Sonata with JBL premium sound when we swapped the stock radio for a Android Head Unit, so went Android unit-aftermarket harness-SLC4-factory amp- front and rear speaker, subwoofer was fed straight from HU , it helped not only with the right output level but also helped with adding better grounding, we tried with and without and made a huge difference, it's also cheap and good quality, instructions are clear and helpful, I'd buy again if I want to keep the factory amp and a aftermarket stereo on a future car

Works well
Works perfectly. It's a little hard to use, putting in the speaker wire and screwing down screws is slightly challenging, but the price is excellent and it works exactly as it should.

Easy installation, works with factory amp
Works great! It sounds amazing on my Bose 2000 Miata LS. I didn't even need to change any of the gain adjustment settings; I just set it on factory amplifier. Wish the ground wire was longer, but you can extend it easily. Installation was very easy, just had to clamp down head unit and car wires to it (only ground was too short). Good price, specially since I don't have to tear out the bose sound system.
