Dear Sir
I'm Mohamed from Egypt. I do have a Harley Davidson Street Gide 2014 with BOOM! BOX 4.3 Standard Radio, i want to change the front speakers and add amplifier and rear speakers in the lids, so a friend of mine was traveling to the USA so he bought me those items:
1. Soundstream ST4.1200D Stealth Series
2. Polk Audio DB652, DB
3. POLK Audio DB692 DB+
4. Metra Saddle Tramp BC-9720 Backbone Rear Speaker Extension Harness
5. Metra Saddle Tramp Amplifier Wire Harness #BC-9715
6. Metra Saddle Tramp BC-9723 Saddlebag Speaker Harness
I did install them in the bike, the front speakers sound amazing but the rear speakers there is no sound only i can hear air sound, i don't have a proper Harley dealer in my country to tell me where is the problem, Is there a special flash for the radio to support this amplifier ?
I'll be thankful if you can help me fix this issue.
The rear speaker outputs from your radio are not enabled by default. You need to either have the radio flashed to turn them on or split the front channel radio outputs and use them for front/rear amp inputs if rear fade is not important to you. If rear fade is important, and there is no local HD dealer, perhaps there is an audio dealer that has a flash device like the Technoreasearch Alaris. If not you can purchase one. If you want to split the inputs to the amp, and are using high level, you may need to convert the radio output to low level RCA using
