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 tapped my hi-lo converter to the sub connector. And the remote turn-on to the Bose amp turn on.

No problems what so ever with my nav or bluetooth. the only thing that happened was that my 'voicetags' for the phone got deleted but I only had three so i re-recorded those.

Bluetooth/nav > 'bangin' system.

 

My volume went low too but it's not unusable. When I use the phone I just have to turn it up, but it works fine. It's a pain when the call cuts out though because then my stereo volume is high. I've just trained myself to turn it down or turn the radio off before making calls.
