Just recently got my system installed which consisted of aftermarket comps up front, 2 12" subs in the rear, a 5-channel amp to power them, and a jbl ms-8 processer. However I've noticed that my navigation audio is super low and bluetooth phone calls is all but unusable. I'm guessing with the bluetooth, that the ms-8's processing is to blame, however I can't explain the nav audio.

I'm seriously considering pulling the JBL MS-8, but before I do, I want to know if the problems I've experienced does not exist for people who are just running a straight connection to their amp(s)?

 

I am running a straight connection to my amp and have no problems whatsoever

 

Are you just grabbing the front left and right channels from the factory harness and hooking them up to the amp?

 

sorry but i cant answer that much, i didnt do the install, all that i am positive about is that its running straight to the amp

 

Thanks. I appreciate any helpful info I can get.

Also anyone running just front comps and a sub and have the center channel disconnected?

 

I have ms-8 installed and have no problem with the navigation. Don't know about Bluetooth, I haven't used it since I installed the audio system. Make sure you have the navigation volume turned up.

 

Navigation audio is up. Can you tell me what you used for inputs for the ms-8. I'm wondering if I may have fubared something.

 

I used the front left and right signal coming from the HU to the bose amp. Just tapped into the wire with a RCA cable that I made. Are you using the signal FROM the amp or the HU?

 

This is what I tied into.

(33) Front Right + (R)(Red) **Preamp from HU
(34) Front Right - (G)(Green) **Preamp from HU
(35) Front Left + (P)(Pink) **Preamp from HU
(36) Front Left - (L)(Blue) **Preamp from HU
