Hello,

I have a 2004 Olds Alero in which I put two amps and two 10" subs in the truck. I have a pair of 5.25" and 1" components in the front doors.

My Infinity 611 runs my two 10" MTX Subwoofers. My PPI runs my 5.25/1" Polk component

Most GMs have side mount terminals. In order to put any kind of audio set up in my car, I have two options. 1) Buy a GM plug(bought one and didn't like it)

2) Buy a battery with both side terminals and top posts.(this is the I liked)

I ran 1ga though my car and into a disterbution block, which divided into four 4ga. At the batery, I connected the car's electronics to the side trenimals where they belong. And reserved the top post for audio only.

So my question is, after only running two amps, why do I get a lot of green corrision onr the positive and brown on the negitive? We are talking alot. I put in arond 50- 75 amplifers in my life and never saw this before.

Thanks for any info,

Tom

I know the gasses it admits has alot to do w/ it...And in your case...Your are probably draining/recharging quite frequently...You can by a vent tube kit and redirect the fumes...Also a spray protectant does help some...

Basically, the combination of moisture, electricity, and metal create what is called galvanic corrosion, causing wee bits of metal to migrate about and causing corrosion (the same proccess is used to make zinc galvanized steel). The best you can do is eliminate one of those components and since you can't get rid of the electiricty or metal, cut down on the moisture.

Is the corrosion mostly on the top terminals...The underlined stuff was from a post...

What you are seeing is a combination of out gassing, and terminal exposure.

To properly clean any battery terminal you must first clean the posts and terminals with baking soda & water solution.
What this mixture does is counter act the chemical reaction which is / has taken place.
If you do not null this reaction, it will come back shortly as you see now.
Once the bindings & terminals are washed down, then you must also add dielectric grease compond to the terminals.
This insulates the terminals and bindings, promotes the current transfer process by ensuring a consistent mating surface.

This was posted by TEKEN...What the heck happened to him...(different name now...?) Also what type of terminals are you using...?

BTW...You can always replace terminals...What size is the ground from battery to chassis...Maybe upgrade...?
