I have an annoying hissing coming from my speakers. I've noticed it the last few weeks. I turn the car on and it will hiss for a few minutes then, all is good. I can turn off my car then turn it back on after it has stoped the hissing and it won't hiss. If I leave it for 30+ minutes and come back and start my car it will hiss. I've had my system hooked up for 2 years. I have approx. 1500 wrms going to two 12" L7's.
Any information to the problem I'm having is much appreciated.
The gain on my amp is down. It doesn't hiss anymore after a minute of driving. But, it happens every time I start my car. I'm begining to believe it is my alternator. Could this be true. Is my charging system weezing down. I do have a stock alt.
I really don't think it's my gain. Why would it only hiss for a minute then be completely clear?
I checked the grounds on both amps. I have them screwed in to a couple of bolts in the back underneth the seat. They both looked good.
I can't imagine what's going on. My amp has worked good for about a year now. I have a JBL 1200.1 GTO. My component amp is an alpine 340. I've had that for 3 years.
