I have a similar problem, couple years ago i got the BSW stage 1 kit, about like 6 months ago the front right speakers (tweeter, mid, bass driver) stopped working all together. Called BSW and they think its something with my amplifier. Now like three days ago they finally came back on which completely shocked me, but stopped working again the next day. Not only that, but today as i leave my house i notice the left front speakers weren't playing, so now there is only sound coming from the rear. They came back on later like an hour ago, but the right side is still out. So I'm guessing its my amplifier thats messed up? I have non dsp, bsw stage 1, dice silverline pro. Where is the factory amp located and is this a common problem?
