Works Well

I installed this the day I got it, simple, straightforward, easy to use. Just don't lose the little plastic flathead that comes with it for adjust gain levels :)

Great Value

I used this to work with a Bose factory sound system with a replacement alpine stereo. Installation went well with no special adapters needed.

Better than hoped for

The product performed exactly as stated. It was easy to understand and apply and was cheaper than any thing comparable we could find.

Great product

As with the others I found that the gains/screws are a little delicate, but that's just up to you to not manhandle it during the install. I love the control it gives me and the multiple setup options. Compact in size makes for an easy install. Good LOC at a great price. If you need a LOC, don't hesitate.

Great Product

It does what it is supposed to do. It is a great product except for the case that is a little cheap and that has nothing to strap it or screw it down. I am very satisfied with its performance and would recomend it to anyone.

Broken Already!!

I got this for a low budget system and thought it would be ok but the little plastic adjusting screws have all broken off and now I can not adjust any gains etc...I now have to buy another one and will be getting something of better quality which is what i should of done the 1st time..

cool product

I installed the Scoche SLC-4 in my 1995 Audi a6 so I could use an aftermarket (jvc) car stereo. the original bose audio system is a common ground remote amplified system and like most modern head units, the output is amplified at the head, so this device provided the signal step down needed to employ the existing remote amplifiers. The unit is a commercial grade device and the instructions are clear and thorough. Overall the quality of the sound is great with no snaps or pops and plenty of volume for the amplifiers. Its the perfect product for this type of application

Great Product!!

I have a stock stereo, the line outs would not work with 2 other adapters.. just horrible sound quality or virtualy no sound at all. This one worked great right off the bat!

Installed with Monsoon sound system, in a chevy camaro.

Great product

An excellent solution to those not wanting to replace their factory stereo. For my 2001 Prius it would have been an ugly and expensive custom installation. Now I have great speakers and a 4 channel Amp controlled with my factory stereo.
