I have a 2007 Chevy Impala LS. I installed an after market Pioneer radio that supports Bluetooth, dvd, and a backup camera. I installed an Metra Access GM data bus, RAP module. I am only getting about 5% volume on the front speakers and tweeters. Hence, Bluetooth isn’t any better. After checking the problem exists with the factory radio as well. Rear speakers work great. Any suggestions would be very appreciated. Thank you!

check wiring on passengers side near the rear hatch speaker, the rear door speakers are run through them also. i had the same problem and it was a unplugged connector at that location
