Default Amp and battery spark

Everytime I hook up an amp to a battery I get a large spark. It doesn't matter if I connect the positive or negative lead first. It also doesn't matter if I connect the amp first than the battery second, or vice versa. I even tried connecting an amp to a stand alone battery in my living room just to see it power on and I still got the spark.

I would like to avoid this spark issue because it leaves a nasty mark on the amp inputs and battery terminal. Can anyone provide me with any advice to prevent this from happening. I would greatly appreciate it.

Put wire in amp first and then connect them to battery bank or whatever

Just arc it on the tool you're using for the set screws for a sec

the spark is the initial charge of the internal amp caps.

Take your power wire fuse out first.....or what massive said if your setup is more complex.

"Center speaker has been cut, possibly by manufacturer and appears to be professionally repaired with black tape. This appears very professional and might be by design. The tape used is not some cheap electrical tape, but a light fabric-like tape. I assume if you are bidding on this high-end speaker, that you are an audiophile and aware of the origins of the anomaly."

TaylorFade, are you saying I can take my live wire that is connected to the negative battery terminal and touch it to an allen wrench to get the spark, than attach it to my amp terminal with no spark. Can I than do the same with the live wire that is connected to the positive battery terminal. Will either of these actions affect my batteries in any way because one is an XS Power Lithium 15K and the other is an XS Power D3100.

ones the amp sparks, its charged for ~30 sec for a minimal arc. touching it to the terminal will pre charge it. you only need to do it to one polarity (I suggest negative)

Yes. That's what I do. My screwdriver and 'T' handle are scarred like a mofo. Lol.

I'm not sure what you mean about the battery terminal one. Like Jeff said... it's just charging up the caps in the amp. Something has to get that shit in there. Better the tool you're using than your buss bar or terminals or whatever.

If the option exists though... best bet is to use the inline fuse (which you should have out already anyway).

When repairing my amp I put a halogen bulb in series with the amp terminals
It slows the charge up rate to about 2 seconds

Or simplest would be Taylor's way
