The front speakers output are 100 Watt each the the center 25 watt the rear 7.5 Watt.
Hope this helps.

I figured it out....

PL-600 TT to the Phono input; PD-M423 to CD input; Cassette Playback to Tape In; Cassette Record to Tape Out

Hello randon_dicks,

The inputs to the LOC should be tapped from your rear speakers. If you have the color code of the wiring from either the cassette player or from the vehicle wiring, tap the wires behind the dash. If you do not have the color code, you can tap directly from the speakers. In either case, it's best to use good quality twisted pair wire and keep the wires as short as possible. Likewise, use good quality RCA cables from the LOC output to your amp location.

Hope this helps.

Hello ryan_jaime,

It's good that you have an aftermarket Mazda wiring harness. It will allow you to make all of the connections in a well-lighted and comfortable location rather than fumbling around behind the dash.

If you are somewhat skilled at soldering, the most secure, electrically conductive, and positively insulated splices are made with solder and heat-shrink tubing. You can get the needed equipment from any Radio Shack, Lowe's or even WalMart. Be sure to put the heat-shrink tubing on the wires BEFORE you solder them together. I had to say that! Because I've forgotten many times! But if the soldering route is not for you, get properly sized insulated inline crimp splices and the appropriate crimping tool. Match up each wire by function on the Pioneer harness with the corresponding wire on your aftermarket harness. Most of the time, the wires will be color-for-color matched. But make sure, sometimes wires for things like "illumination", "dimmer", "mute", etc may not be the same colors.

Disconnect the negative battery terminal while you are working behind the dash. After you have the harnesses spliced together, plug the radio end into your Pioneer, remove the old radio from the dash opening, unplug the antenna and wiring harness plug and plug the other end of your spliced harnesses into the vehicle plug and the antenna plug into your Pioneer's antenna connector. Slide the Pioneer loosely into the opening, but don't secure it yet. Reconnect the negative battery cable and test the receiver. If everything works, slide it into the dash opening and secure it. Use the rear support stud and rubber bumper if needed. Install the trim ring or separately purchased dash kit as required. Put the "face-fixing" screws in to prevent removal of the faceplate if desired. Reinstall any dash trim removed and you're finished.

Hope this helps.

Its pretty much useless. Unless you can find a wiring schematic from Pioneer for that particular unit. If you managed to obtain a schematic (very unlikely as its Pioneer's property!) you might be able to cut an existing usb connector and join it where the old cable was cut off.

With a DC voltage tester, check the two power leads for 12+ volts and proper operation, and be sure the unit is properly grounded.

The two power leads are,

1.Constant feed: which should be connected to an un-switched power source that delivers continuous
power to the units memory.

2.Switched feed: which should be connected to a switched power source controlled by the vehicles ignition switch.

Before installing in dash check unit for proper operation.

Good luck

to install this unit in your car........as a beginner i would strongly recommend buying a aftermarket radio harness (this harness will attach to the wire plug in your factory deck simply unhook the factory player and attach this harness to the plug you just pulled out of the factory unit) once this harness is installed on the factory plug it will be a simple colour match (just attach wires to pioneer wires IE. red - red, white - white........once all the wires are attached install in dash recommend buying a mounting unit for this net part it will hold the deck in place in your dash...........after that is done install your pioneer unit push it in place apply power by turning car on..........pioneer deck should turn on and work if it does not turn right on look for a source button on the pioneer unit and hold it down till the unit turns on
good luck
hope i was able to help

I could not find that model but this is one that is comparable.

Good Luck

Why not plug the cassette directly into the CD recorder? Are they trying to achieve some eqalization change? If not, then this should work. It's all analog at tape level.
