OKay... Hooking up subs and amp in truck

Power on amp fine. I believe the problem is the rca outputs on the radio...

I have a car that I tested the amp and speakers in and was fine.

The only difference is the head units. The head unit in the truck was used previously with a different amp and worked fine.

Okay so, the amp is "Alpine - 4/3/2 Channel Plus Subwoofer Drive Power Amp"

The rca inputs are as follow - White on top, red on bottom...

* * *

* * *

Left Top & Bottom = Channel 5 Subwoofer

Middle Top = Channel 3

Middle Bottom = Channel 4

Right Top = Channel 1

Right Bottom = Channel 2

The head unit in my car has a subwoofer output too and is what I used to use channel 5 and worked.

The head unit in the truck only has 1 rca output.

You have to actually put your ear on the sub to tell its getting a little power( in the truck )...

its not the radio because i took a rca output and hooked it to the ipod in both the car and truck and it worked in the car but only had very low sound in the truck...
