hookup of JL Audio XD600/6 with Technic's harness - BMW 3-Series (E90 E92) Forum

digitaldav · 05-27-2011, 06:42 PM

I am using Technic's harness to connect xd/600/6 to my High fi. My question is there is only 2 RCA female jack inputs, front and rear from the harness to the amp. I understand these would be connected to channels 1,2 front and channels 3,4 rear. I would then select 4 channel on the amp. The sub left and right output would be connected to channels 5 and 6. Does that sound right?

Does this sound right or am I making no sense...

Another ? I have is why does Technics harness have female rca jacks and the amp also has female jacks. Shouldn't they have male ends so can plug right into amp inputs?

1) the harness isn't just for that amp. other amps fit other places.

2) if you'd gotten the amp from us we would have included short RCA for you.

3) we also preconfigure the amp so that ch 5/6 are created by the internal summing of 1 3 and 2 4. If you read the manual, you will see how to do that...

I got the amp from a friend that gave up on his install. I see in manual were channels 5/6 out is created by summing of 1.3 and 2.4.
So would the underseat subs be connected to channel 5/6?

Page 7 on the XD600/6 manual:

Set Input Mode Switch to 4 channel

All my harnesses are compatible with all balanced-inputs aftermarket amps thus male RCA extension cables are required -exactly the same as all aftermarket HU female RCA outs are configured.

Therefore the OEM HU/iDrive in the HiFi is converted virtually into an aftermarket HU with female RCA outs when the HiFi harness is plugged in.

Thanks Elias,
I PM'd you..

Technically, Technic's harnesses are NOT compatible with all aftermarket amps - ONLY amps with true balanced inputs on the RCAs. I know that's what he meant, but if someone misread it, poor results would ensue...

How do I know if my amp has "true balanced inputs on the RCAs"?

What about a basic Alpine like these?

MRX-F35 or MRX-F65

?

Thanks.

Stay away from the MRX Alpine line, I have sent about a dozen of those amps back to Alpine.
