Have a jbl mb3319 siruis ready stereo in pontoon boat with polk subwoofer and speakers. removed battery over winter time. went to start it up, the stereo and amp have power, but speakers are not working, won't play ipod or radio station. can tell the amp is getting power but the sub woofer wont come on. last season when turned on, the speakers would make a "pop" sound so we could tell it was on. wondering if there is there a reset button somewhere? Misplaced owners manual :( thanks in advance for any help!
A Subwoofer is very simple piece of electronics. Check all of your connections and your receiver's surround modes. You shouldn't need the manual to do a preliminary check on this. There might also be a problem with the subwoofer output on the receiver. Also use a tester to see if there is current on the wires coming out from the receiver. Try it with just one sub-woofer at a time and see what happens. You may not have the power to run them all or you may have a short on one. Also check the condition of the speakers themselves. Rats can eat into the speakers themselves and like to chew away at the wires. Weather exposure can also dry and crack the rubber in the speakers.
all the connections look fine, it appears to be some sort of output issue that we can't resolve. The turner and amp have power, yet they are not sending any sound to the speakers. There doesn't appear to be any damage to the speakers or wires. The speakers themselves are enclosed, there is no visible sign of any animal entry on the boat. there is a subwoofer control knob, and the light is not on to indicate the sub is on.
If you have a fuse for the sub-woofers check it, if they are powered off the Amp you will need to test that since you said the amp is working. If it uses an 8 pin or 4 pin power connector you may want to make sure that the pins aren't bent. It sounds like you've narrowed it down to a power issue, there aren't a lot of places the failure could be occurring.
