Has worked great and came with everything i needed to install a Kenwood amplifier and 2 subwoofers great product at an amazing deal with an open box discount

Very cheaply made. At least Bestbuy makes it easy to return and get a better replacement!

The Metra Line Output Converter is a solid choice for anyone looking to add an aftermarket amplifier to their car’s audio system. The installation process was straightforward, and the adjustable design made it easy to position in my vehicle. It effectively converts high-level speaker outputs to low-level RCA outputs, which is exactly what I needed for my setup. The sound quality is clear, and I haven’t experienced any distortion or noise issues. The build quality is decent, and it feels durable enough to last. One thing to note is that it can get a bit warm during extended use, but this hasn’t caused any performance issues so far. Overall, the Metra Line Output Converter offers great value for its price and performs its job well. I would recommend it to anyone needing a reliable line output converter for their car audio system

Excellent and affordable LOC. Doesn't have some of the features like crossover etc of the more expensive brand LOCs, but every amp I have ever used already had a build in crossover anyway so that is not a big deal. Easy install and setup. The unit is a lot larger than I expected for such a simple design, which did make it a bit difficult to find a good home for it in my Jeep Gladiator which has very minimalistic body trim panels, but I was able to double side tape it to the inside of the B pillar and I think it should hold there fine.

literally just used it too install straight to OEM stock radio and my subs hit so good with it easy install easy instructions definitely do it yourself really easy. Saves the hastle for someone else.

It works and it’s at a good price. Good quality device

Easy to install, Very compacted so easy fit, Nothinv to complain about here.

The best the for your subwoofer you will not regret it buy it

Perfect for the car amp setup. Seay to install and great quality.

Wiring was self explained and the price was perfect. The sound is clear and it’s small enough to tuck into places easy

Works great with the stock speaker, wires, and easy to hook up

Works great, very simple and easy to connect, would highly recommend.

Small price tag, BIG improvement in sound quality! Easy to hook up in under 10 minutes.

I bought them expecting to run audio from a head Unit wired into an rca input but it didn’t go. Not sure why. Maybe it’s one directional.

Great Product for the money best buy never let me down when I purchase product from them i always get my bang for my buck

I had an amp that only worked with sepaker wire and needed this to put sound from my computer to some speakers that only took aux input. this + some adapters saved my day.

I thought it would be crappy sounding because of the low price but it actually sounds pretty good....

works insanely well with my dual 10s. 10/10 would teco
