Best box setup for 2001 tahoe

Was wondering what would be the best box design to in my 01 tahoe. I have 2 DD 9515g and startin with just 2 M1 DD amps going to 4 M1 amps later (have to build electrical up). Any Ideas will be helpful

get your hands on a spec sheet for those subs ... find someone with a boxpro program ... find a few tahoes with subs installed and listen for "your" favorite sound ... go from there ... personally i'd build the electrical up as much as possible before anything else ... not enough battery power might hurt your amp ... let alone 4 ...
less amps on larger subs draws more current from the electrical system and amps get hot and burn up quicker ... just my oppinion sir ... hope this helps ...

thanks all ready got 200 amp alt and just ordered 2 kinetik 2400 batts that should hold the electrical part i hope the box thats in there now is forward firing ported at 35hz with a 23 degree face got alittle to much airspace tho it has 6.5 cu ft per sub i think it need 4 cubes per sub

2.8 to 3.2 sealed per 15 old school specs ... tune to 40 htz with 1 4 " round port per sub (separate chambers per sub) ... subs up, ports up ... should be awesome ... too much airspace can also hurt a sub by making it FLUTTER while playing music ... like i said please check your spec sheet for correct airspace for THAT particular sub ... each one is different ...

With 2 Amps per sub I would do 2.5-3 per sub and if your doing one box common chamber i would do subs up port back with 3- 6" aeroports tuned to the frequency of your choice 36hz should be fine for your vehicle.

i am with kenny b those trucks love subs up an port back. the tuning you have to play with yourself in your truck cause if you build a box an tune like some program says it would be close an it won't be far off either.
6.5per sub is WWWWWWWWWWWWWAAAAAAAAAAAAAAYYYYYYYYYYYYYY TOO MUCH AIRSPACE FOR ONE 15 i don't care what sub it is.
i have had 2 15's in a trunk car in a 4.5 or 5cub box an it done fine until i played a song that was tuned wayyyy lower than my box was tuned an it shreeded one sub. (my fault by the way lol)
good luck with what you do bro

thanks for all the input

I agree with kenny, but I would go with4-6inch aeros and that would be 3cubes after displacement. What is your intention with this setup though?

my setup is subs up port back, the further back the louder until 13 inches it peaks. mine is a 02 hoe with 2 trf 15's and 1 t3000. it does a 150 easy and 149.8 with music at 40 hz

we metered mine at a shop with my messed up box did a 152.3 i dont realy care about the meter but want it to be loud on the street. Im building another truck for comp. Working on a 00 two door blazer. Going to do 4-18" 9518 and 8 m2 amps to start with get more power later.
