Hey guys, I have a new issue I'd like to run by ya.
I installed (replaced) my tower amp with a kicker 200.4 and installed a new 700.5 to run my cabin speakers and an eventual sub. I installed Polk DB's in the cabin, and they sound great. However, they sound great when the boat is off. :(
I was finally able to get the boat wet this weekend, on a nice blustry cold spring day, and was syked to get the tunes rocking. Well, I come to find out that when the key is on and/or the engine is running, I've got a high pitched whine in my speakers. I assume it was also coming from the towers, but didn't check that. Now, here's the kicker:
I put the key to the on position, and everything powers up, Perfect Pass does it's start-up screen saver thing. The high pitched noise starts when the perfect pass display turns on, and then the noise goes away (once the "into" is done on the perfect pass). This is for when the key is just in the on position.
Now, when start the boat, the noise will pick up at the same point, when the perfect pass display turns on; however, when the "intro" on the perfect pass goes away, the noise stays (again, when the engine is running). The noise doesn't increase as the RPM's increase, but seems to track the volume of the speakers.
I assume this is some sort of grounding issue. I do have my speaker wires near my power wires on my amps, I know this isn't good, and I plan to move that. I also plan to replace the RCA's with better, shorter cables. However, I am baffled why I seem to be getting feedback from Perfect Pass. I have PP Digital Pro, and it's an 08 LSV. I only have 1 battery (at least right now, in the planning stages of a dual battery install), and all my grounds on my amps go to said battery. I did not check to make sure they were tight on the binding post however.
I hope I answer some of the questions you guys might ask me, so, put your thinking caps on and let me have it!!
Thanks in advance guys!
