I have a Lexus IS F w/Mark Levinson Audio System, will be adding an Illusion Audio Carbon C12 subwoofer and Mosconi AS 200.2 Amp

So, I need help figuring out the best LOC for my need... AudioControl LC2i, Caché CLOC+D, Mosconi HLA-SUM?

Also what should I tap into from the factory ML amp... Sub Output, Front Woofer Outputs, or Both (Sum)?

 

For your simple addition, a super expensive LOC/Processor is really not needed. Any inexpensive LOC will fit the bill. You would be looking at the $15-$75 range for what you need.

As far as connections...... You need to be grabbing signal prior to the amp. Your new amp wants a low level signal. Personally I am unsure if the signal going from the HU-Amp is low or high level on your car in particular. Confirm that first before grabbing signal

 

LC2i is around $70-75, it accepts high level signal (up to 400w)... the other two mentioned LOC are high level as well, but I am just trying to figure out if it's best to get the signal from the front woofers, sub output, or would it even be necessary to sum both?
