tune it down in the 40hz area if it were me

You would be better off doing removable ports, tune 1 to your competition, which is usually in the 50hz range, and another to your daily tune, which is around 38

A wee bit small of air space for those subs, but it should suffice.

Subs up, port back. Make sure you leave room for the port to breathe off the back hatch.

You have to pay for box designs around here, generally. It's only around 10 bucks though, somewhere in there, and most of the people are relatively knowledgeable.

I would tune them to around 38 if it were me. Then again, if you tuned at the 44-45 you wanted you would do better on the lab, it just would have as much authority in the lows.

Best of luck.

i found that every suv we've tested with, i can only think of one exception actually, the box very very close to the back of the vehicle was the loudest.

It will be tough to squeeze 6 of those subs ported in that amount of space...

What kind of charging system are you planning on?

i agree with 2 inter-changeable ports, daily port = ~35hz, comp port= ~45hz+.

sometimes you cant have the best of both worlds, best way to do good daily and comp is to have interchangeable ports IMO. 45hz tuning for daily probably wont sound very good at all, but 35hz tuning won't get you the highest numbers either. you can go in the middle, 40hz or so if you didnt want to have to change ports for competition.

I got 1' of room from the port to the rear hatch door,IF i keep the depth at 33"...Is that good or should I go closer to the rear hatch door? 7 1/2" inbetween the port to the last panel on the carpet BEFORE the rear door...LET ME KNOW what would be BEST

I'm still wondering how you plan on keeping those amps voltage happy.

 

[SPLIVIN 10+ year member]

HAHAHAHAHA!! Im working on that right now?? This kinda was a last min. build..But I dont plan on keeping it in the tahoe for daily....Maybe go back down to 3 12's for daily.....i don't know...If so should I just do an SPL box? I did the Big 3,got a Kinetik 1800 In there right now with the fac. batt still in there also...And yeah I know I NEED hella alot more to keep these amps happy but running out of time...
