Excellent guide mate. Very easy to follow to those that have taken things like this apart in the past.

I use an Ampcontrol LC6 and it does the job but prior to the install, if I had come across a guide like this, I would've done it for sure.

Two thumbs up....

How many volts P-P do you see from the pre out?

I didnt cro the ICC , just the audio board

I used a freq. generator to see where I needed to go.

so I dont know how much the icc feed the amp board

Ok so you were just injecting a tone to find where the input to the Audio Out IC was.

So you havnt measured the output of the RCA's? How many volts P-P is now coming out of the ICC?

You need to know the level coming out on the RCA's to set the input sensitivity correctly on the aftermarket amp. Anywhere from 1-4v P-P would be nice.

havent put a CRO on the output (my CRO is build in my pc) so its hard to have the icc and the pc close , but as a guide , my fusion monoblock gain is set around the middle(but I also have the remote on this)

Well we cant call it a CRO then, its just an oscilloscope for political correctness. Would be good to know what the level is for curiosity's sake.

true true , thanks for the correction

Well I'm glad that's sorted!

well thinking about in I am using a CRT , so in a way its still a CRO

Your right, I just took an assumption that you would have an LCD monitor.

im poor :(
