Scosche LOC2SL Line Output Converter with Remote Control Knob - 2CH High/Low RCA Converter Car Audio - Ideal for Subwoofer Amp - Line Level Converter for Car Stereo - Easy Installation - Quality Sound

The Scosche LOC2SL line output converter works well and passes the signal cleanly without any noticeable loss in sound quality. Installation was straightforward and it lets you connect an aftermarket amp to a factory head unit without any issues. Overall, it does exactly what it’s supposed to and keeps the audio clear.

Got this installed in my 2008 Toyota Avalon XL after a painstaking process... And it sounds great! I'm using it to power a 750w amp and two 350w subs with my stock head unit. Note, Camrys of this generation have the same wiring colors. Didn't have to adjust the gains for my left or right channels, just tapped into the rear speakers (Left Rear - Yellow with Grey stripes (+) , Black with Grey stripes (-). Right rear - Red with Grey stripes (+), White with Grey stripes (-). I tapped into them on the seat belt column area. I suppose you could do it at the head unit, but I felt safer doing it behind the seatbelt column panel. You can tell they're the speaker wires because they're the only wires intertwined together. The rest of the wires on the harness are not. I used wire taps where you crimp two wires next to each other together with a piece of metal, so I didn't have to cut wires. To get the 12v constant, I simply crimped the wire to a 5A fused line, then crimped it to an extra wire, which I stuck into the "B+" input on my amp, joining it with the power line from the battery. For the ground I did the same thing, routed the wire to the GND input on my amp with the ground wire stuffed in there. The Remote wire actually works very well and for now, has not given me issues. I was relived to not have to route another remote wire from some electrical part of the car, and I could just crimp a wire onto the remote wire from the LOC and connect it to my amp. It only turns the amp on when the radio is on. Perfect. My only fear is if the LOC Remote wire circuit malfunctions for some reason and causes my amp to kill my battery or something. Maybe there's a protection built in for that. Didn't seem to work at first and I thought it might be defective, but I re-did a few connections and it worked! I noticed more bass immediately and knew it wasn't my interior speakers. I connected the bass control knob, which I routed through the interior panels and it works flawlessly! It has a very wide range and is quite sensitive, at least for my set up. Turning it all the way down will essentially turn your sub off, so that's nice for when you need to go incognito! Couldn't be any happier with this. I didn't want to mess around with an aftermarket headunit so I decided to save myself a lot of headache and money. This will do the trick as long as you can tap into the right and left positive and negatives. Of your speakers.

I lost the bass knob to my Kenwood amp many years ago and always wanted a replacement. I've bought several Scosche products over the years and while the build quality isn't the nicest, they've always been robust, reliable products in my experience. Anyway, on to the product itself. Very easy to install; just connect the yellow wire to the Positive/BATT connection on your amp, the black wire to Negative/GND on the amp, and the blue and white wire to the REM/Remote connection on the amp. Finally, connect the remaining wires to your rear speakers. Just follow the color coding in the manual and note that you will need to run additional wire to the speakers (not included). Then turn up the gain to the loudest you would ever possibly want it to go without clipping/distorting. This will be the the same volume as the loudest setting on the bass knob. Finally, find a place to mount the knob, and you're good to go. Scosche was nice enough to include double-sided tape in the box, in case you don't want to drill holes to mount the knob. I found the bass to be much boomier at first compared to my amp's own speaker level inputs, but this was solved by simply turning down the gain knobs on the adapter, using the included adjustment tool (a mini slotted/flathead screwdriver works too). Anyway, I can't complain. This actually works better than my original bass knob that came with the amp, which worked like a bass boost rather than a gain control. My original knob would only turn UP the bass at certain frequencies, but not down. This Scosche knob adjusts the entire frequency range of your amp all at once, and can even be used to mute your subs entirely. 9.5/10 would recommend (0.5 taken off for build quality). Will update the review if anything changes.

This bit of kit is fantastic works as it should easy to plum in im getting another one for my bmw to wire up my subs with the factory headunit can't rate enuf

Very good adapter 👍👍👍👍

The install was fairly straight forward. Just a word of warning. If you don’t need the remote line to power on and off your amp, don’t connect the power cables to the LOC. Just hook up the speaker wire connections and you’re good to go. I don’t need a remote amp power on because I’ve got the amp hooked up via an on off switch and 12v line. Still when I hooked up the power wires to the LOC, I was finding that the car battery was clearly getting drained the next day when I tried to start it up. I then disconnected the power and ground wires from the LOC, and my car battery has been fine ever since.

Have purchased 3 of these over the last few years for various cars and never had any issues.
