Old school stereo in dash with knobs cassette player, 6 speakers, someone told me I can’t use the old speakers because there amplified or something, trying to find out if I have to put in new speakers and wiring to upgrade new stereo ? Anyone know anything about them ? Thanks

Hi Jiml100,
Many units do come with a separate amplifier, and then those feed normal speakers. If all you need is a new single-DIN AM/FM/MP3 player, here is a BOSS at Amazon for just $24. One like this would use your existing amplifier & speakers.

There is radio speaker switching relays shown on the wiring diagrams as well as volume controls in series with some of the speaker wire leads, so you will want to study the diagrams for your unit. So you may need to do some research to try and figure out what wires do what and what the audio outputs of the existing radio are to see how to match up a replacement. Good luck.

You can view all of your wiring diagrams in this folder:

So I would just have to figure out the color code on the rv plug, which ones are the 4 speaker wires and it would run the amp and everything ?

When dealing with the Wiring Winnebago has added we may have a big help on ID for them.
They use a stamped code:


This will not be on the wires which come with any item that has a factory wire set that then plugs into Winn wiring but on the Winn wiring! Like at lights, there is often a wire set on the light but we need to pull out the slack and find it connected to Winn wiring! It gives gauge and color of wires as well as from and to locations.

To cut time scrolling, hit Ctrl and F at same time to bring dropdown. Enter the search term like wire ID or "speaker" and it then brings all places those show up.

Not a perfect system and audio is pretty sketchy stuff but maybe a help?
A big help when wondering which is battery and which is ground!

I replaced the Magnadyne 1.5 DIN radio in my 2004 35U with a Kenwood single DIN. I bought a kit from Magnadyne to mount the single DIN radio. I bought a molex plug that matched the Magnadyne plug. I soldered that plug to the end of the Kenwood pigtail. Plug play then. Magnadyne had a wiring diagram I followed. I didn't use there single DIN radio as I had the Kenwood laying around. It has a hand remote. Does hand free calling and Bluetooth audio. I put the same radio outside. My 35U had the surround sound option. Don't recall its name. It worked with the Kenwood as well. I moved the TV/Radio switch from the passenger overhead to the dash. I kept forgetting to change the switch and it couldn't be reached while driving.

I would like to have installed a double DIN but that would require cutting up some metal behind the radio opening.
