Review: 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. Review: Working so far, but not a quality part - I used this to integrate into my factory BOSE amplifier/speakers with an aftermarket Android head unit on my 2007 Nissan Armada LE. I read the instructions (as well as reviews) and was very careful when torquing down the speaker wires. I would have preferred to put wire ferrules on the speaker wires and then connect them to the LOC but I did not have faith the screws would be strong enough to crush them properly. Ideally, I would have preferred to have a wiring harness (like on other LOC units) so I could solder the wires from my head unit and have a more secure connection. The gain controls seemed flimsy - I followed the instructions not to push down as you turn them but had to apply an uncomfortable amount of force to break them loose initially. In my case, I had to max them all out (I suspect due to the weak signal from the Android head unit) and the arrow on one was not aligned to the others. That said, everything is working and sound is now good but I worry about how long it will last as the entire unit feels fragile. I also recall using one of these units in the past and having it fail so I do not have a lot of faith in it. As another reviewer noted, the colors on the pre-outs were not correct (switched red/white for front back) but I used the labels as a guide. All in all, assuming it keeps on working, it's hard to beat for the money. Just don't expect LCI quality. ## Features - Unmatched Versatility - Compatible with a wide range of car audio systems, this high to low converter offers flexible installation options, making it a go-to solution for converting speaker wires to RCA line level signals or adding an aftermarket radio - Seamless Integration - Integrate your factory stereo with an aftermarket amp using this line out converter and boosting your car’s audio performance without complex rewiring.

What is more to the point is what application you have on mind. **Q: Saab 2009 9-3 w stock radio, no Bose. looking to add a sub for bass. I will add an amp for this. Can i tap this units inputs from rear speaker?** A: Yes just make sure you get the polarity right **Q: when they say 80 watts max per channel, are they refering to the output power of my factory radio? my amp puts out 125w x 4 RMS** A: Factory radio but even tho your radio says 125 x 4 that is a max rated not a RMS rating so you will be fine **Q: trying to install sound system (head unit, amp, subwoofers)to 2010 impala that has the stock Bose system. Will this be powerful enough to support that** A: This item is meant to reduce the signal strength from your aftermarket head unit before it goes into the stock amp, in this case, your Bose stock amp. If your intent is to continue using the Bose Amp to power your stock Bose speakers, this item does the job. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy installation, works with factory amp *by A***C on March 19, 2026* Works great!
