My Preferred LOC for adding subs to a factory stereo

JL Audio’s LOC is very easy to set up. Great instructions and build quality too. Demo’d against other leading LOC’s and was superior in my application. Highly recommended.

Amazing product

I used this loc in my 2006 Cadillac stsv to get more sound in the bass department. And I say this has to be the best loc converter yet. No buzzing noises. No thumps from it turning the subs on and off and the ease off where you could mount it was amazing. Hands down 5 stars!!

Lc2i killer

A week ago I decided to give the jl loc a shot after owning the lc2i for the past 6 months. Let me tell you! This thing makes a world of difference. The jl loc destroys the lc2i under 30 hz and it has a distortion detector to ensure clean output. Was a bit more difficult to hook up with the signal detector but I even eventually figured it out. If your subwoofer enclosure is tuned to 33hz or under you have no business with a lc2i installed, you need the jl loc 22. Thank me later.

Excellent product best loc on the market

The Jl audio line output converter is perfect, I have had other locs that had too many adjustments that had to be made on them just to get a decent sound out of you factory system but the jl audio loc has only a gain control setting nob very very very easy to use you make all your sound adjustments from your amplifier this is the way it should be. Jl audio has been around for years and this company knows about car audio systems, with this loc your factory stereo will sound just as good as that premium stereo on the market if not better very very clean solid BASS from your factory system. Thanks, JL Audio you made a simple to use a product that works better than anything else out there on the market. Thanks, JL audio

Excellent product

I had originally purchased and inexpensive passive loc. It worked but the base roll off killed the sound. This is the ticket. I was hesitant due to the price but very happy with the results. Very easy to dial in.
