I am hooking up a JBL MS-8 DSP with the stock 2008 G37S COUPE system.

two questions:

1: POST amp, can I find any full signal speaker wires. I need one full right signal and one full left signal. I am thinking the rear mids might be full channel speakers. Any thoughts? When I say full, I mean full range, not filtered down or cutting off any frequencies. If I had a probe I would be able to determine this myself.

2: My car is in the shop or I would check myself. Does the NAVI and Bluetooth audio come out of the center speaker or all speakers. I cant recall.

 

If you want full range, then you want pre-amp. Any speaker signal will likely not be full range. If you can't personally tell the difference between the two with your own ears, then what's the point of using a probe to test for it? Just don't amplify an already amplified signal (speaker level). It's like making a photocopy of a photocopy.

Seems to come out of front speakers, but I can't tell if it's coming out of the center speaker too.

 

bitnine - I need to make sure I have a full range signal not for my listening purposes but for the dsp. I hardly think most people can tell if say 80hz and below is being cut out from a 6 1/2 inch speaker, but of course a probe could.

I would tend to agree that it seems to make more sense to grab the signal pre-amp but I am being told directly from Gary Biggs of Harmon (JBL/Infinity) to grab the signal on my car post amp. Gary Biggs is the #1 premier car audio tech in the country. I will have to give him a call and have him clarify.

So I guess most people dont know if any of the post-amp speaker wires are full range. Again I was guessing if ANY are it would be the rear 6 1/2's in the side rear portion of the car.

 

Anyone anyone?
