| | Stereo speaker distortion
I bought a combo head unit and speakers from West Marine - the "step-up" version - $149 for the combo - not the $119 version. The head unit itself sells for $139. I installed this stereo and speakers a couple weeks ago as a replacement to the old head unit and pseakers. I left all the old wiring in place. Just swapped out the head unit and speakers. The speakers became very distorted at a volume level of 22 out of 45. Ok for trolling speed, not so much for underway.
Thinking this was due to the crappy speakers, I bought new West Marine Pro speakers - they sounded very good in the store with the head unit that I bought. Going all the way to 45 with almost no distortion. I swapped the speakers out tonight trying to get ready for our offshore trip Saturday and not much better. Gets to about 25 out of 45 before too distorted to listen to.
I have swapped wires on the speaker posts checking to see if it was a polarity issues. I also isolated each speaker with the balance to see if it was only one of them. No luck.
Last piece of information which probably makes this officially too long of a post... The old stereo had a wiring harness coming out of it that plugged into another harness to connect all the wires on the boat. Because there isn't much slack in the wiring on the boat, it would have been very difficult to cut off the plug on the boat side and hardwire everything inside my electronics box. There are only wires coming out of the back of the new head unit. So I used the wiring harness from my old head unit and wired the hard wired the new head unit to this harness to plug into the harness on the boat. I also used the same speaker wiring. And I think it must be said that the stereo that was on there that was replaced, had this same distortion issue.
All that said, replace speaker wire all the way to the boat side harness? (fairly easy) Remove the harnesses all the way and hardwire everything together? (may require splicing some additional wire on there - not so easy) Or is there something else I am missing...
Thanks for taking the time to read this and for any information!
