I used this Scosche LOC to add an aftermarket subwoofer to my factory stereo in my 2023 WRX, and it worked perfectly. The installation was straightforward, and the wiring instructions were clear. It provided exactly what I needed.A lot of cheap line output converters introduce static or distortion, but this one delivers clear bass without any unwanted interference. If you’re upgrading your car audio setup and need a reliable LOC, this is a solid choice!

Works as it should. Super glad I didn't have to go in the dash board. 1 hour to install. Like that it has bass control knob accessible to driver in addition to settings on the unit.

I bought this for my son's sub amp and speaker installation. He had received an amp and a pair of 12 inch subs for Christmas. I needed this to tap into the high level speaker lines for the signal for the amp. The installation seemed straightforward enough but I encountered several problems. Once the system was wired exactly as specified by this and by the amp wiring diagram the system worked and sounded good. All seemed well. We went to bed that night and guess what......the next morning the battery was dead in the car. Out came the charger and that issue was resolved. The next day.....the same thing.A complete check of the wiring showed no stray strands, no bare wires pushed too far in grounding on the amp case, etc. There were no points where any wires were rubbed bare against metal, etc. Much research really turned up nothing so I took matters into my own hands. I disconnected both the hot wire going to the amp itself and also the so called remote turn on wire from this LOC going to the amp and guess what.....no more dead battery. I played with the car a couple of days, played the normal stereo, etc. and all worked fine as before. This made me confident that something was going on with this box, the amp or a combination of the two. Since my son is off at college 100 miles away a dead battery in the morning when leaving for school is not an option.I did some more research and bought a Stinger relay for the main 4 ga power wire. I cut my feed wire, ran it through the contacts on the relay and then wired the coil of the Stinger across a low usage relay in the relay fuse block under the hood. Then to be doubly safe I bought a little $5 four pin relay from the auto parts house and powered the coil off the feed wire for the amp and the ground. Then I ran the remote turn on through the contacts and viola......no more dead battery issues. The car has been ran for a week now with no problems, the volts are staying exactly where they should be, etc.This combination means that the amp has no power until the car key is turned and energizes the Stinger. Then the feed through the Stinger gives power to the other relay to complete the remote turn on circuit. Then if the radio system is turned on the remote turn on will let the amp energize and we have sub sounds.I really have no complete knowledge of what the issue was but just that this box did not work as it should have based on expectations. My son's car has the fancy Microsoft Sync hands free live telephone system and communication package so I have gleaned some knowledge since you can basically speak and the system will power up and allow you to make hands free phone calls or texts, that there must be a low level live signal coming to the speakers that effectively makes this LOC keep the amp on standby even though the amp power light is off. My wiring solution solves all that.With all being said and done.....the LOC works well, we have the sounds we wanted and everyone is pleased. I would recommend this LOC but would just advise you to take my mods into consideration if you encounter issues like I did.

Added a subwoofer about 2 years ago to the truck and wanted to keep the oem radio and this worked great! It is still holding up and eventually about 6 months ago I changed the radio to an aftermarket one however was still able to keep this attached which made swapping the radios more easier.

This works great to add a powered sub to my 2 channel outdoor amp (converts the speaker level outputs to RCA for input to the sub). Note that it does require a 12V supply. Sub level adjustment works great as well.

If I’m being honest. It never worked. I tried many different methods to get it to work on 2 different vehicles, 2019 Camaro, & a 2023 for F150 . & nothing. I recommend using a harness to save you the trouble!
