I have the Bazooka CSA150.1 250 watt amp and a Lanzar 250 RMS/500 watt peak. i can turn my truck on to acc. and the sub will work but when i turn my truck on, the sub will be hitting for only a couple of minutes, then the amp will turn off. But after that, you can turn the truck back on acc. and the amp will run great... what could be causing this?
Thank, Bryant
That's a new one on me.
The only electrical difference is the battery voltage on ACC is 12 volts. When you start the truck the alternator should put out about 13.7 volts. That would make me suspect a bad power supply in the amp or the output transistors, something in the amp is getting hot at the higher voltage and shutting it down
That would explain why you get two minutes ,and than when you turn the truck off the voltage drops back to 12 volts and the amp comes out of protect mode. Try a amp swap or if it's a self amplified tube, hook it up to a friends system.
Never hurts to put a voltmeter on the battery with the truck running, and off, to make sure the alternators voltage regulator
is not faulty and exceeding the rated voltage.
Good luck, let me know what happens, I'll ad it to the book.
Regards Paul
