Line-Out Converter Specifications

Number of Channels
Each channel on an amplifier will power one speaker using a positive and negative cable. There are various types of amplifiers, each designed to power a certain number of speakers. Monoblock amplifiers, also known as single channel, are designed to power one or more subwoofers. These amplifiers often have very high power ratings. On the other hand, multi-channel amplifiers power multiple speakers, usually at lower power ratings. 2-Channel and 4-Channel amplifiers can power car speakers or low powered subwoofers. Occasionally you might see a 5 or 6-channel amplifier that can power speakers and subwoofers at the same time. The most common setup is a monoblock amp to run subwoofers and a 4-channel amp to run door speakers. Check out our Knowledge Base for more information.

Maximum Power Input
This is the maximum amount of power (measured in watts) that the unit is designed to handle. Exceeding this amount can void warranties and damage the unit.

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.

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.

Does the trick

July 11, 2008

This product worked exactly the way I needed it to. I used it to run a sub woofer through my friends stock receiver. I ran the signal from the rear speakers to the inputs on the converter and used rca to go from that to the amp. I am very impressed with this product. I was one of the only things I could find that did that. Money well spent.

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.

works great

December 29, 2011

I have bought 2 of these and had no problems at all with the first. The second one gave me problems when trying to secure the high level input wires. The screws would not hold the wires in and I ended up dropping one of the little clips so I soldered the wires in and then taped them over to make sure they didn't pull loose. Other than this it works great and gives you good control to balance out the feed to the amps.

cool product

March 7, 2014

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

Really good

August 8, 2007

This is a great LOC. It can be used for OEM radio or with an aftermarket radio that you want to tie into the cars OEM amp. I used it for the OEM radio and a Boss 5 channel amp. At first I ran the speaker level inputs to the amp and it was really weak. Then I connected this between the radio and amp. Huge difference. This made the amp come to life. Buy this, don't use the amp's speaker level inputs.

I little more difficult to tune then other, less expensive products, but then again, it is tunable. The gain can be adjusted, but must be done carefully as slight changes affect the volume dramatically. Once it was installed and set up, I didn't have any problems with it and would recommend it to anyone.

Not the One

August 16, 2013

Bought this to run a OG '77 delco 8 track & a 2011 Sony Xplod deck in ny caprice

Hooked it all up ran RCA thru RCA splitters to the cd & LOC then to amp

Cd player sound fine but 8 track only played OK at Very Low volumes
When turning it up even a lil bit results in excessive distortion
Adjustment of gains gave little help

Sad to say I'm thinking if removing the delco for a 7" monitor or maybe leave it for show

Looks well built
Plastic housing ..well everything
Small gain adjustment window

Get better quality or stereo specific converter (ex.. delco, bose, etc)

I recently wired in a subwoofer by tapping into the wire from my Bose amp. I was told by numerous installers it would be at least $500 to finish a proper install on a subwoofer. This product allowed me to do it on my own for $20 bucks. With a little know how and some determination this product simplified my install...thanks!

Great Noise Blocker

June 6, 2010

Purchased this specifically to get rid of the alternator whine in my system. It knocked it out COMPLETELY. Zero whine now even at the lowest volume setting. This unit has 4 transformers inside so it has some weight to it even though it doesn't look like it. Use your own small screw driver. Had no issues with connectors. Very good unit for the money.

I am trying to install a JVC unit into my 1999 Avalon. The unit does not have preamp outputs on it. Is (SLC4) what I need to make the unit work in m vehicle? I have the interface cable for the car that has the RCA plugs attached
Jon H on Feb 11, 2015
Best Answer: Hi Jon,

Yes, the Scosche SLC-4 is what you seek. It will take the Headunits 'High Level Speaker Wires' [i.e. White (+)(-), Gray (+)(-), Green (+)(-), & Purple (+)(-)] and turn them into usable 'low level' RCAs to your harness. Of which, I assume looks very similar to the Metra 70-8112.

I'm just trying to replace old factory cd player in my car. My car has factory installed "2 ohm" speakers with small amps each in F&R. Do i need this line-out converter(SLC4) to connect Pioneer 6700bt(designed for 4 ohm) to the speakers? or I can just connect them without it? Thank u for any help.
A shopper on Dec 10, 2014
Best Answer: Hi, I purchased this unit to do 1 easy thing for me. I purchased an Alpine head unit with only 1 set of pre-amps for the SUB. Soni used rhis unit to get the line outputs from the headunit sobthat i can have 2 sets of preamps (front & rear) to run a 4 channel amp to all four door speakers. My whole system is 4ohm. I replaced all 4 door speakers and bypassed the Bose internal amps due to their high 8ohm rating. This made the best sense to me & my whole system sounds amazing now. Hope this helps!
