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.

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! 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.

It’s palm sized and quality is good. Recommend for the price. Lot of instructions given, so very easy to install. Love it. Recommend to buy, amazing price. Put this cause my Goldwing stock amp hi level was too hot and this made it so much better ### ⭐⭐⭐⭐ Working so far, but not a quality part *by P***Y on February 14, 2022* 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. ## Frequently Bought Together - Scosche SLC4 Line Output Converter/OEM Premium Amplifier Adapter - 4CH LOC High/Low RCA Converter Car Audio - Add New Amp or Retain Factory Amp - Line Level Converter for Car Stereo - Quality Sound - Metra 70-1786 Radio Wiring Harness for Mercedes 94-04/Landrover 99-04 - Metra Electronics 40-VW12 Factory Antenna Adapter to Aftermarket Radio Adapter for Select 1988-2005 Audi/BMW/Mercedes/VW Vehicles (VWAB) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/6664745-scosche-slc4-line-output-converter-oem-premium-amplifier-adapter-4ch](https://www.desertcart.tn/products/6664745-scosche-slc4-line-output-converter-oem-premium-amplifier-adapter-4ch) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-15*
