On the xmdp10110 witch is pos and neg

Would you rip apart your personal computer and then ask which wires are what?

should be red pos, black neg.

it depends on the amp what can it handle. will it do 2 4 or 8 ohm is it 1 ohm stable are the subs dual 2 ohms or dual 4 ohms. 1042s are dual 4 ohm subs so if you wire them both in paralel it will drop both subs into a 2 ohm load for each sub that is pos of one coil to pos of sec coil then pos to pos on amp and same with neg to neg to neg on amp. now if your amp is 1 ohm stable i would do both subs the same way you will get the most power out of the amp. but itll run a littl hot if you dont have adaquate power running to the amp. now i wanna think your alpine amp maybe only 4 ohm stable. i would run both subs like i had said pos to pos then neg to neg now both subs will be a 2 ohm load so what you do to bring it back up to 4 is you run the 2 bridged subs into a series which is pos from one sub to neg of the other sub the remaining pos and neg will run to the amps pos and neg. which will make it into a 4 ohm load. now the last scenereo is your amp is 4 ohm or 2 ohm stable. this is how to wire it to 2 ohms and not 1. take one sub go pos to neg then pos to pos on amp and neg to neg on amp this will make an 8 ohm load with one sub take other sub and do the same neg to pos on sub then pos to pos on amp and neg to neg on amp this will tell amp to run a 2 ohm load. 2 ohms is a good run for these subs if the amp can handle a 2 ohm load. now if you would have given the amp model number i could have looked it up to just give you what you needed but with this short info i gave all possibilities.

white are left front, gray are right front, green are left rear, purple are right rear. solid color wires are pos.. and with black stripe are neg.

pos to pos and neg to neg for 12 volt but if your system is 24 volt thats a different story it will be pos to neg.and pos to neg

Normally right positive and left neg. Your amp should have indicators on the terminals. Of the four you should have a separate + and - for each channel. This tells you which channel is for pos, and which is for neg. If no markings switch for each one left pos/right neg or right pos/left neg. It will only work on one way.

1988 toyota tercel sedan as follows

pink = (+) pos. for left front speaker
violet = (-) neg for left front speaker
light green = (+) pos. for right front speaker
blue = (-) neg for right front speaker
blue/yellow = (+) pos at all times (power)
grey = (+) pos. only in the accessory or run position
brown = (-) neg gound
red = (+) pos. right rear speaker
black = (+) pos. left rear speaker
white = (-) neg right rear speaker
yellow = (-) neg left rear speaker

if its cutting off and right back on then check your ground and your power wire makes sure both are connected good and none of your fuse's are blown, either that or you got a wire hooked up backwards in the sub.. but my guess is that the sub is hooked up wrong... that sub should be hooked up in a series or in parallel,

ok if your running just one speaker, it should be hooked up like this and 2 speakers are a different way...

this is parallel :pos to pos , neg to neg, then one wire coming from pos on sub to pos on amp then neg on sub to neg on amp but bridge the amp on your amp should be 2 pos and 2 neg in two different channels take the pos off the sub into the pos on 1 channel and then the neg from sub to the neg on the other channel,

this is series : on the sub it will go pos to neg then the other neg and pos will go to the amp, but make sure the pos and neg r on different sides of the sub, dont hook them both to the same coil

if your need more help give me your email and ill send you a pic of how to do it...

Use a DVM.

Do you know how to use a DVM?
