I recently purchased a: Bazooka BTA6100 BT Series 6-Inch 100-Watt Amplified Tube Subwoofer.
I installed it, in two different vehicles and in both of the vehicles it does the following: It powers on, and works for about 2 minutes, then it turns off, and then after about 2 seconds or so it powers back on. This pattern continues indefinitely.
FYI: I have it hooked up without the remote lead, with the harness/clip that came with the tube and I am using only the RCA outputs of the head unit as the sound input into the tube.
Does anyone have any ideas?
