Wiwing question HELLO...INSIDE THE SUB ...WHAT IS THE SMALL WHITE AND BLACK WIRE FOR?...I HAVE AN AMP OUT OF A S120PII THAT I WANT TO USE ...I THOUHT THAT THOSE TWO SMALL WIRES MIGHT BE FOR A THERMAL SWITCH...I CHECKED THE MANUAL NOTHING THERE...THANKS

Do you have any wiring in the panel already? The green or bare copper wires will go the ground bar which will be screwed directly on to the inside of the box. The ground bar will be in contact with the box. If the mains are wired into the main lugs the main ground will have a green stripe or it may be bare multi strand aluminum. All ground wires go under screws individually on the ground bar. The white wires go onto the neutral bar. The neutral bar will be affixed to the inside of the box on plastic isolators that do not allow contact with the metal panel. The main neutral will have a white stripe or it may be solid white. The neutrals will go under individual screws. The hot wires will now go under the screws of the breakers. All screws must be tightned firmly but not as tight as you possibly can. The hots will be black or red. The wires should alternate black, red, black, red. Begin with black on the top two breakers the one left and the one on the right. The hot wires will be either black or red.

If you look on the circuit board that the big black heat sink is attached to, there are two output amp chips (integrated circuits) attached to it. IC7 is the sub output amp. Next to that is a white jack with two pins sticking out, labeled J9. J9 is where you plug your sub into.

Hi,

Basically the wiring of the large harness corresponds to the pins like this.

Starting in the upper right hand corner and working down the right side from A12 down to A1.

1=Left rear output-red
2=Left rear output-blue
3=Right rear output-black
4=Right rear output-yellow
5=empty
6=Left front input-black
7=Left front input-yellow
8=Left rear input-orange
9=Left rear input-green
10=Amp 'ON'-blue&orange
11=empty
12=Amp sensor-black&orange

Back up to upper left hand corner on the large plug

13=Right front tweeter output-red
14=Right front tweeter output-blue
15=Left front tweet output-red
16=Left front tweeter output-blue
17=empty
18=Right front input-red
19=Right front input-white
20=Right rear input-blue
21=Right rear input-red
23=Right front sub (+) output-yellow
24=Right front sub (-) output-black

The small harness is the same above with the upper right position being pin 1 going down to pin 4 then back up to the top for pin 5 down to pin 8.

1=Memory Power-Lrg White
2=Amp Ground- Lrg Black
3=Left front sub (+)output-yellow
4=Left front sub (-) output-black
5=Left front mid (+) output-white
6=Left front mid (-) output-brown
7=Right front mid (-)output-brown
8=Right front mid (+) output-white


Hope this will help you.

Thank you

Hello, here is Clarions wire codes.
FRONT Right SPKR: +Gray -Gray/Blk,
FRONT Left SPKR: +White -White/Blk,
REAR Right SPKR: +Purple -Purple/Blk,
REAR Left SPKR: +Green -Green/Blk

Brown Wire = Phone Mute Lead (If applicable)
Yellow Wire = 12V battery lead in (Connect directly to battery)
Red Wire = 12V Ignition wire (Connect to Acc switch)
Blue/White Wire = Amp turn on lead
Black Wire = Chassis Ground
Orange/White Wire = Illumination Lead (Connect to dimmer switch)
Blue Wire = Auto Antenna Lead (lowers power antenna Do not use for Amp Turn on! Use the Blue/White Wire for Amp,EQ, Ect.. turn on wire only

RCA Connectors if applicable:

Black RCA Harness:
White RCA = Rear Audio Left Sub Output 1
Red RCA = Rear Audio Right Sub Output 2

Gray RCA Harness:
White RCA = Front Left Audio Out to amp
Red RCA = Front Right Audio Out to amp

Yes, keep in mind that the amps have a constant power (the large red wire) and need a remote signal to tell them when to turn on/off. This wire connect to a switched 12v from the ignition or radio blue wire (if aftermarket)

Hello moore_broder,

Your MTX 7801 is stable at 1 ohm, but you cannot wire a pair of DVC 2 ohm subs to that impedance. They can only be wired to 1/2 ohm which is too low or to 2 ohms.

Series the voice coils and parallel the subs. On each sub, jumper Black to Red/White Dot, then run both red's (positive) and both black/white dot's (negative) to your amp terminals.

The diagram is here.

Hope this helps.

Hello nicole_murra,

The green wires are for signal input to the included amp and should be connected to a pair of RCA preamp outputs on your head unit. The thin blue wire connects from "remote" on the amp to a switched 12V output on the head unit (usually blue or blue/white). The red wire is for power and goes through the fuse to positive battery. You also need to connect the amp terminal marked "ground" to the metallic chassis of your vehicle, within a distance of about 1/2 meter or less. There's usually a short piece of wire with black insulation included in most amp wiring kits. If your Fusion sub did not come with such a wire, you can use any wire that is the same gauge (or bigger) than the red power wire.

Hope this helps.

Same thing happened with me. Did you ever find a solution?

1st--on 1 sub put a wire connecting one red with white dot to the blk with white dot
2nd--do the same thing to the other sub !!do not wire a red/white to an all black
3rd--wire the full blk negetives to the amp, then same thing to the positive
