Box help/recommendations for 2 12 T1s and other questions!!

[JMastermind]

Im going to be getting the new rockford T1s with the T1500 and what size box should I go with to get the best sound and loudness...and what tuning would be best? Its going to be sealed off facing the cabin, I heard this is the best way to go with subs so Im gonna do it this way this time,

Also pushing this power should I get a second battery and put in the back or just get one good battery and put it in the front? I was thinking jus adding a kinetik in the trunk with a relay

Go on the RF website and they have recommended box sizes there. As for the battery, a good AGM battery under the hood should be enough.

For box size look at rf says then look at how much space you have design a box with the space you have and if it does not Mach rf then don't get the 2 12's may be just 1. Also as for the amp big 3 and upgraded batt in front and I would say a second one in the back will help a lot to. If you add the second one in the back make sure you use 1/0 wire for your run to the back and grounds then what ever size wire te amp takes

Go slightly larger on volume than recommended. And also, tune a bit lower than rec.

Ran the same subs, on a 2500bdcp. And I went straight across the board on RF's rec's.

IMHO, more volume, and a bit lower tune would have been optimal, even on that power.

I feel that rf's spec, are VERY generic, for a broad base of buyers. Just me.

Good luck with what ever ya do.
