Hi All......Hoping I can get some insight on a stereo issue I am having. I have a 2005 37PC. I replaced the factory stereo amplifier with a Memphis Audio MXA480.4 and the factory cockpit speakers with Memphis Audio 6.5 in hardtop and 6x9 in factory locations. I added a 10" sub under the helm seat. I used the factory wiring to run the amp and 4 speakers and ran a new wire from the amp to the sub. 3/4 channel bridged with internal crossover. The stereo sounds great for my needs but the issue I am having is after about 3/4 volume the factory circuit breaker for the stereo amp trips. Any thoughts? I didn't think I was adding that much as compared to the factory system. Thanks in advance for any input. Jason
