I have a sony 480 watt amp powering a 12 sony sub enclosed in a bandpass box. my problem is that after about ten minutes or sometimes less the bass cuts out for about 5 seconds and then comes back. if i dont turn the stero off it continues to do this repeatedly. my volume is usually about halfway up when this happens but sometimes it does it reguardless. is it the ground or do i need a bigger amp?
I have a sony 800wtts max amp, I had the same problem since a couple of months ago, tried everything to solve it without success. Yesterday the amp finally gave up and barely moves the sub anymore even at half boost.
turn the gain down a bit and see if it helps Sony amps are notorious for this though and often end up failing. they're very poorly made and have caused countless people headaches with their abrupt failures for no apparent reason
Yup my amp apparently failed, it barely moves the sub now, you have to almost touch the sub to see that its recieving signal. I checked all the wiring and the sub and they seem fine. I guess the amp finally decided to fail, anyways I ordered an alpine amp, hope i have better luck with them : /.
