Have a 2005 Itasca Suncruiser with the Magnadyne M9999 radio installed. This model has the CD player and cassette player. I am upgrading to a new Pioneer DEX-X7500HD head unit and had a question on the wiring.
I believe there is an amplifier and subwoofer in the current configuration but the Magnadyne manual makes no mention of wiring to this amplifier or to a subwoofer. Is there a wiring diagram that lists the wiring for the installation as it now exists. The Pioneer unit can support a subwoofer but I do not know how this should be connected. I want to be sure I don't miss-wire anything and I don't want to lose the subwoofer if I can figure it out.
Not to be smart mule but, you should know, not believe you have an amp and sub. They are easy to locate. Listen for the speaker and the amp should be rather conspicuous as it gets warm and therefore not surrounded by much stuff.
My brother has a 2006 Suncruiser 35a. Today we replaced the outside Magnadyne with a pioneer. The wire harness from the coach plug to the existing radio had the same numbers of wires and colors as the new pioneer harness. We cut all of the wires on the existing harness and coupled them together with like colored wires on the new radio harness. I may be wrong but I do believe that if you remove the front radio and cut and couple as we did it will work well. In his coach the front radio is wired through the VCR then to the see round sound. So if we replaced the front radio we would wire it this way.
Thanks all. I was able to gather up enough info to start the install yesterday. No real surprises as the wiring color codes from my new Pioneer to old Magnadyne matched almost perfectly. One thing I did note was that while the Magnadyne supports front and rear speakers, the wire harness that feeds the speakers only supports the front. there are no wires to the molex connector for the back speakers.
Another issue was that the new Pioneer was about 1/2 inch too deep and hit the metal brace that was part of the original radios mount. It also blocked the connections. I had to cut the back portion of the brace off to make room. This is not a key structure so I felt ok in cutting in off.
