2005 ford ranger.

i removed the stock head unit and replaced it with a Jvc. I'm running 2 12" rockford punch subs and a 1200 watt sony amp.

in my older civic when i hooked up my amp there was 2 12v power wires running from the CD player, one from the head units wiring harness and then 1 from the wiring harness you connect to the head unit (the kind you have to buy and use when installing an aftermarket CD player)

in the ranger there is only 1 power wire and it's the one coming from the harness that connects to the head unit. there isn't one from the aftermarket connecter that connects to the head units wiring harness. i hooked the blue 12v power wire to the amp, ran the ground, ran the 4g power wire to the battery and ran the RCA cables and nothing, the amp light is not coming on. i know its not the amp or subs, both are brand new and worked fine in my friends civic when i checked them

help me out!

well after reading for hours and googling.

12v wire(blue) runs straight to the amp which i knew, ground goes on bare metal nothing painted which i knew, 4g red power wire goes straight to the battery with the fuse a few inches less then a foot from the battery which i knew, RCA cables run on the opposite side of the battery power wire which i knew, i've done everything right, i haven't blew any fuses.. i haven't ran any wires the wrong way. the only thing I'm clueless of is the 12v wire, i for some reason remember there being one from the c.d. players harness and one from the aftermarket harness that goes into the stock wiring adapter from the car, but there is only the one from the c.d. player harness, i feel like that doesn't pump 12v of power.. come on, someone has to know something.

I'll do my best. The head unit will need 2 power wires. One 12v full time to the units memory, usually going to the orange radio wire. You may have to run a separate wire to the fuse block for this. Make sure it's on a fuse that's hot all the time. The other will be the switched 12v wire to the red. Black to ground and blue to the amp remote. The rest will be speakers.

On the amp you will have your 12v source, straight off the battery, ground & the blue wire which will act as the on & off switch to for the amp. You need to have 12v on the blue wire when the radio is on to power on the amp. Connect the blue to the remote terminal on the amp. Plug the RCA's & it should work.

Also on the amp, you can use a jumper wire from the 12v to the remote terminal and the amp should power on. If not check your ground to the amp.

I'm sorry if this doesn't make much sense, been sick all week and still not 100%
