Hi all, First post after lurking for way too long. Hope I can get some advise. Here's my system: Alpine CDE 113BTHAL JBL GTO 6ch amp JBL GTO Components (front) JBL GTO Coaxials (rear) JBL GTO 12" sub Today I decided to do a better job of the install as the previous installer seemd to know even less than I do. The speaker wire was a little messy and I wanted all speakers and sub running from the amp as opposed to off the HU amp. So, I have re run all the speaker wire from the amp to individual speakers (getting through the door gromets was a nightmare) however, my new HU doesn't have the same 3 x RCA outs (front, rear, sub) that my old Alpine unit did... instead it has 2 outs (front L&R or Sub/Rear L&R or Sub), take a look: Looking at the * eplanations; does this mean I have to choose between the use of my rear speakers and my sub? Surely not!, or are they expecting me to run the front speakers from my HU amp? Please help!
