A little help guys

[htownbballstar2]

So here is what I bought....

Polk MOMO 6500 components for the front doors

Polk MOMO 690 6x9's for the rear deck

Gonna hook those speakers up to the Kicker ZX350.4 amp

Kicker 12" CVX(hook it up to the Kicker zx750.1 amp)

Pioneer DEH-P4900IB head unit

Here are the questions that I have....

For the sub, would a sealed box 25" wide, 14" and 14.5" deep, sound decent? I have a 2002 mitsubishi galant, so there is plenty of trunk space, but I would still like a lot of trunk space left.

As for the component speakers, where should I place the tweeters and crossovers. I was thinking putting the tweeters in the "A" pillar and the crossovers under the passenger seat, would that work? Any other ideas? Come on guys help me out //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

And I am going to upgrade the battery to a Optima Red Top, but is it absolutely necessary that I have to do the Big 3, or will I be fine without it?

Thats around 2.9 cubes before displacement sounds a bit big, what does Kikcer recomend?

thats fine my tweets are in my a pilar and x overs are in the doors, but under the seat is fine

Upgrading the battery is always a good idea and doing the big 3 will only make things easier on the flow of electricity

By the Way nice equipment

Well some guy told me that 2-3cu ft would be good for a 12" comp vx, I just called up kicker and they said anything over 1.5 and I wont like the way it sounds. 1.5 is gonna save me sum trunk space
