Car stereo installation speakers

Replacing a car stereo system in an older rv.
the old cassette player / radio has four + wires for the speakers and possibly only two or one - wirre.
The new CD player/radio has four distinct + and four - wires. is it possible to install the new radio using the existing speaker wires ( joining all - wires to one - wire) or will that cause damage to radio or speakers?
Here's hoping someone can point me in the right direction,
Thanks

Your old unit was a common ground unit meaning all speaker grounds as well a radio ground were the same. The new unit should NOT be connected to this wire configuration. Newer units change the potential difference of the speaker power meaning that the - wire of the unit may have negative 24v on it so IT CANNOT BE REFERENCED TO EARTH OR CHASSIS GROUND.

I would recommend rewiring the speakers to the radio for best reliability and sound quality.

How do I replace the in-dash radio in my 2002 Fleetwood Bounder 36S gas RV?


Should be a normal install. Remove faceplate and skinny nuts on the volume and station preset knobs. Remove surrounding plastic,if necessary. There will be a rear support bracket at the back of the unit. Some wires back there.

I WANT TO ADD A CD PLAYER TO MY 2001 GRAND MARQUIS


Go to a Salvage Yard or contact Car-parts.com which is a collection of online parts salvagers. There were optional radios which had this feature and also a 6 CD stack for the trunk.

The biggest thing would be to make sure the wiring is compatible if going to a trunk mount. But a dash mount single radio/CD is probably the cheapest way and I would think the speaker wires should be compatible.

The manufactuers used a 4 pin lock system in the front dash facing of the radio. You can get the simple release pin barbs at Walmart or most autoparts places. Just insert the barb pin stems into the 4 square holes and press and the radio should come out.

Plastic box of wires to big for my new cd player after taking my old cassette player out


You wll need a stereo installation adapter kit. This will change the dash opening to the size you need, oftentimes by replacing an entire dash panel for a factory look.

Here is a link to the dash kit for your car at Best Buy. These will come with detailed instructions. Let me know if this helps :)
