QuestionI have a Clarion radio model PN1632M-C from a 2001 Nissan Sentra. I put it into an old pickup. On the back of that radio are two harness sockets. One has 10 spades and the other has 6. The wire colors for the bigger one are white/left front, white with black stipe, grey left front, grey with black stripe, power antenna (not going to use),yellow, black ground, orange, orange with black stripe, red.
The wire colors and designations on the other harness which plugs in next to that are: green left rear, green/black, blue/white amp turn on, black/white amp turn on, purple right rear +, purple/black.
I have my amp from high school days, that is in very good condition. It is a Sanyo PB3000, 30 watt total power, 15 watt RMS, 4 and 8 ohm impedance, 11-15 volt DC neg ground. It has a socket with a plug that has on one face up: 4 ohm output- black ground, orange speaker, green unit, red +12 voltage, yellow unit, brown speaker.
If the other face is up it reads: 8 ohm output- brown speaker, yellow unit, red +12 volt, green unit, orange speaker, black ground.
I have 4 Pioneer TS-G1647 speakers, two way, 6 1/2", 150 watts max, nominal 30 watts, impedance 4 ohms.
Can you tell me how to connect the harness, amp and speaker wires?
Thank you very much.
AnswerHi Stewart,
First off, I must admit I'm completely clueless regarding the Sanyo amplifier. From what I can tell, that must be a good 30 years old. I can't find any sort of documentation or installation instructions for it; and the wire colors and labeling are outside of my experience.
The fact is, I'd question whether the amplifier is really necessary in your application. When that amp was made, it was very common to find head units with power ratings of 7 watts per channel or less. Modern head units can generally achieve 15 watts per channel RMS without a problem; so the amplifier won't really improve on the output power of the head unit, but it certainly increases the chances of picking up an alternator whine in your system. It might be worth a try if you'd like to run more than four speakers in the truck, but otherwise I'd leave it out (and not just because I actually have no idea how to wire it).
If you reduce the system to the head unit and speakers, the wiring becomes fairly simple. Each speaker gets a positive and negative connection to the head unit. You'll find two spade terminals on the speaker; the larger terminal is the positive, and the smaller terminal the negative. The speaker wire outputs on the head unit are as follows:
White: front left
Gray: front right
Green: rear left
Violet: rear right
The black stripe marks the negative lead of each speaker pair.
The yellow wire should be connected to a constant voltage source, while the red wire is meant to be connected to a key-switched power source. Depending on the age of your truck, you may find these wires in the factory radio harness, or at the fuse box or key switch.
The orange/black wire may not have a matching factory wire in your truck. The orange wire should be connected to a factory wire that has voltage whenever the parking lights or headlights are switched on. The purpose of this wire is to dim the radio display at night. If you don't connect it, it shouldn't affect the other radio functions.
The black wire should be connected to vehicle chassis metal. The black/white won't be used in your application; the blue/white is only used if you're installing an external amplifier.
Hope this helps!
Brian
