i got a question and hope u guys can answer it i jus bought a 1000/1 amp and W7 12inch sub i was wondering since i got the 1000/1 amp do u have to change out the infiniti stock battery under the hood? because some1 told me with that 1000/1 amp the battery in my car cant handle it and it might die anytime so i would have to buy a higher performance battery what would u say? ur advice would really help thanks.

 

The battery may need to be upgraded, but plenty of people use the stock battery with the 1000/1.

You should be more concerned about fitting the 12w7 in the trunk in the right size box and not drowning the rest of your speakers with bass.
