SOURCE: Integra install problem
Assuming that your car is a negative grounded car, it should not make any difference in the power supply if the metal is galvanised, zinc conducts electric the same. As long as the ground connection is good, it should work fine.

I've got a pair of these MTX's subs powered from a Fusion 450 watt 2-channel amp. For the price, they are great. By the way, they are 4-ohm.
My first suspicion would be that something in the first incorrect wiring damaged either the amp or the subs. Can you explain specifically what the "installing the subs incorrectly" means? Was the amp output shorted out at any time or was it operated without a load? Either of these conditions will fry an amp and sometimes, the protection circuitry doesn't work either.
First make sure that your amp is still working. Check both the primary power fuse, usually located near the vehicle battery, and the fuses on both sides of the amp. Make sure that when you turn the system on, the power light comes on steady (blinking is protection mode). Test your subs one at a time on a speaker output.

SOURCE: SUBWOOFER NOT WORKING?
I would say that you blew a capasitor on the out take of the amp. All the green light means on the amp is that you are getting power to it, not that it is working properly. If this is the problem it is because you probally tried to bridge a non bridgeable amp. This problem occurs when an amp is not ready to take the 1 or 2 Ohms that come back through it and it blows this little ***** capasitor inside rather than frying the amp, again if this is the case you should be able to open it up and see the one that you have blow. If this is the case get a sodering gun and take the capasitor out, but make sure you mark the - side so that you will know which side to put where (it will be the side with a different color line on it). after that take the piece out to a radio shack or another electronics store and tell them you need that exact piece. After that just soder it back in and see if it works, if it does great if not ..... it is like a $1 part and you can't break something that is already broke. oh and if it does work .... don't bridge it again XD
Hope that helps :)

A FACTORY INSTALLED AMP/SUB WILL BE WIRED INTO THE VEHICLES FACTORY WIRING JUST AS ANY OTHER COMPONENT. YOU WOULD THINK THAT YOU WOULD FIND THICK POWER AND GROUND CABLES ALONG WITH RCA CONNECTIONS AS YOU FIND WITH MOST INSTALLS.NOT THE CASE HERE.YOU MUST FIND THE HARNESS THAT HAS THE POWER AND GROUND CONNECTIONS ALONG WITH THE INPUT WIRES FOR SOUND. YOU MUST OBTAIN A VEHICLE SPECIFIC WIRING DIAGRAM THAT HAS THE WIRING FOR THE SOUND SYSTEM PACKAGE THAT CAME WITH YOUR VEHICLE. YOU MUST THEN WIRE IN THE BLUE REMOTE TURN ON LEAD FROM YOUR UNIT TO TURN THE AMP AND SUB ON WITH YOUR RADIO AND NOT YOUR CAR BATTERY. YOU WILL ALSO NEED TO FEED SOUND TO THE AMP USING ONE OF THE REAR OUTPUTS FROM YOUR RADIO.
