newb question about sound with trunk open

How there is any distortion at all with the equipment you're working with is beyond me!  The impedance load on each amp is an easy 2 ohms, the woofers are 400 WRMS, the amp outputs 500 watts into 2 ohms.....   is this your amp?  I wish I had this stuff to play with.  All the tools are within fingertip reach for designing and building  enclosures for  these subs.  The manual shows you a slotted box.  Why don't you build it and give it a go?  That size looks like it builds in a helluva bass boost at around 50 Hz, though.  Maybe that's what would work best for bassheads, but I think I'd give each sub 1.5 net cubic feet with the same slot port dimensions for a smooth response.  And install a pair of 30 Hz  f-mods to prevent below-tuning-frequency distortion.

If you want to learn how to design your own, get familiar with Win ISD Pro.  It's free and easy to work with once you get the hang of it.  That's what I was looking at.

A tip, too, on picking up more info:  use the forum 'search' button to learn more about specific topics and read opinions already posted.  (BTW, you can respond without a full quote each time...  :)

I forgot to add another option I'm thinking about.  I also have a pair of 10w3v2's.  I was thinking about getting another a pair and running each pair off  a  zapco 500/1.  Hmm, I wonder how much space 4 10's would take up:)  What should I do?  It would be cheaper to go this route.

no i'm not mixing subs. either 4 10w3v2's (each pair powered by zapco 500/1) or 2 12w6v2's (each powered by zapco 500/1)

lot's of good tech...input..one of them made my eye's go crossed  (lol)=0 . big wise...nice bass set up! sound's good in the car right? sound's bad with the trunk open. all of you can picture this( accept archmed..) take the windsheild out=( standing in front of the car now you're system sound's better than it dose inside.. why? think about what you just did accusticly. you gave it gain..by uttilizing the envirment it's in (a speaker in a tunnel or a speaker in a feild. in this application were are dealing with, all of us struggle to find the best of both world's. if you want you're sub's to sound good out side, give them reflection befor they enter the world other wise,they will go every where without control...

nice to get this out!
