2000 watts...extra battery?

[transamfan 10+ year member]

I have a Kicker 1200.1 amp (tested at 1508 watts) and a Kicker SX700.4 (700 watts RMS). I will be pushing one freshly re-coned DD 9515 in a 4.2 cuft box. It will be in a 98 ***** Am and I have 1/0 power wire to the back. I have never built a system with this much power before and I am wondering if an extra battery in the back is in order for this build. I ran the 1200.1 off of stock electical and it worked ok for me, but adding the 700.4 gets me thinking. I don't know what my alt puts out, but I thought that Pontiac put some pretty good alts in those cars, maybe 100 amps or so. I can probably measure it tomorrow if it would make a difference. So, do I need a extra battery or not?

You're best off with a second battery in the back, yes.

Need it? Not so much, but your amps will appreciate it //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Might want to look into an MLA module

and I would look into something like a Kinetik hc2000. It won't leak spill or gas on you.

Hey, thanks for the help. Looks like I don't HAVE to get one. I will try it and see what kind of voltage I am getting and go from there. The SX700.4 is digital and will tell me what voltage the amp is getting, as well as the highest and lowest voltage it sees.
