Blew speakers in Seneca cab

To watch DVD’s on the center (big) TV I need to turn the Jensen JRV215N volume up very loud and the sound is still barely audible in the main area…it’s plenty loud in the cab area. After watching the movie I switched to radio, the cab speaker volume went very loud, and the right front speaker in the cab blew. It now has a buzz in it.

The Seneca has 4 house speakers in addition to the 2 cab speakers. I couldn’t figure out how to get at the cab speakers after removing top dash panel screws and right face panel screws. I can get some panel separation but far from being able to access the speakers. I don’t want to break anything by forcing it too much. Anyone know how to get at the cab speakers? Do I have to remove all of the dash panels? And, no there is no speaker cover to access them…it’s molded in.

The radio has 4 50W channels. I figure that 2 channels are for the cab speakers and the Jayco wiring diagram shows 4 house speakers on the other 2 channels. The house speakers are 50 watts RMS, 100 W peak. With 2 speakers on one channel I’m guessing it’s really driving 100 watts which would explain why the cab speakers are so loud and the cab speakers much quieter.

If I just replace the cab speaker I’m guessing I will still have the same problem. Any audio experts out there to confirm my suspicions? Any suggestions for a fix?

Thanks

I will be watching closely to see if anyone offers any advice. While not blown (yet) I want to change out my dash speakers to provide better sound, may even add remote tweeters to truly bring out the high tones.

I have had my dash apart numerous times to add the Sirius tuner, connect the Alpine subwoofer, add remote locks for the cab, install a side camera disable switch, add foglight switch, and rearrange the switches to move OD cancel switch where it is more easily reached when driving. But all those times apart I have to admit I never paid attention to what it would take to get the speakers out. Shame on me!

Rob / Walt you're correct. To access the front speakers you need to remove all the dash panels. When I installed the driving light switch in the dash I had everything removed including the instrument cluster at which point I noticed both front speakers. Once you remove the panels the speakers are easily seen. The passenger side pulls off pretty easy, driver side and center have a ton of Torx screws. Let me know what you replace them with.

Please, next time someone takes their dash apart take some photos and post it, like step one, step two etc. I would like to add and additional ciregette lighter outlet. There is one now which I use for my brake controller monitor, I need another for my Garmin. I am currently using a double plug in outlet but it's a little heavy for two items which I plug in. I want to add an additional outlet.

I had additional 12v outlets added in the dash when I purchased so I can't tell you how to do it. I purchased them from West Marine - 1 is cigar lighter the other is 2 UCB ports. They're the ones with diagonal stripes to the right.

Did you have to disassemble a lot of the dash? Like the part that goes around the instrument panel? How did you know where to hook them up? Where there only screws to take out in the dash disassembly or did you have to mess with spring loaded clips that are easy to bend and bust?

What did you do for the remote door locks?
