Did you only try sealed up?

My sealed trunk score isnt much higher right now, but mines at about 28hz.

subs up port back. every hatch including my own hits higher that way unless your running aero. with that set up, i think you should be hitting a little higher than what you were tbh.

you have an suv. he has an angled hatch. subs up port back for spl are thee bomb. been proven. but lately i have had some locals that i did a box for (1999 integra) subs up port up subs were up and close to the driver. port was in the rearest part (slot) facing upwards. its still under construction right now mut so far its doing very nice. we should have it at finals this year.

Thing is, my box was actually built for a 2000's tiburon with subs up port back. I made some adjustments to the port when I put it in my truck. That box was hitting 147-149 on music in that tiburon.

tiburon has less angle on the glass. it takes alot to know what is better for what car/person im just voicing what ive been doing. the sub up port back is getting old

I guess a lot of it has to do with the acoustics and tuning of the vehicle. Best thing to really do I guess is just test and tune in all ways and see what works best

My hatch hates subs up, port rear. It likes subs and port up but it has to be all the way to the back and sealed off so the presure dont shot straight down into a pocket. Really a PITA.

So question will I see better number with my port and subs facing forward? Plus the fact that I'll be running around 5000watts lol
Also does anyone know what class I'd be in for idbl and bass boxing? Here's my setup

stock batt upfront and a batcap 4000 in the back, Mid/ highs amp and subamp, then seats folded down with 1 12" subwoofer for now. Soon to be 2 there's a comp on Sunday I'm thinking about going to but don't want to enter if Ill be crushed hahaha

ok u have 2 choices here u could build the box sub up port up and fire off the glass as stated above or i have seen a so to speak wall behind the rear seats and the subs and port firing forward. either setup in bassboxing will put u in featherwieght class. however when it comes to idbl doing the sub up port up box will put u in stock hatch but doin the half wall (so to speak) it will put u in stock pro. if i can make a suggestion on the sub up port up box i would try a port plug with different size and lengths aero ports and i would test the lengths and get them close to the hatch that way u build some sick compression because that is a long way to the meter!!!

also if u are gonna burp u are only allowed 2 runs of 0 gauge and 1 batt in the back. i would suggest using 1 run of 0 gauge for pos and neg and run additional grounds to the back batt also what 5k are u gonna be using?

also if u intend on doin bassboxing u better be able to burp a 53+ on that setup since the INAC champ ended doin a 150.5 avg so u need to be real loud and he is on 2 12's in an exploder.

IDBL stock hatch which was introduced this year the SBN winner did a 150.8 but u better believe that will be beat this year

all in all u need to be burping 53's to be a contender and that is on a national level

subs forward port back does tooo.

Yep that too

Whoa lots of comments. Ok to start since this is the once that stuck out most I only have one run of 0 gauge to my rear. A wall isn't really an option for me I don't exactly have room in my rear hatch to work with I take my TTops down a lot which is why I chose the back seats. And this Is on music still I haven't tried a burp I don't know what frequency to use yet

ok so it looks like ull be running stock hatch in IDBL and still featherweight bassboxing!!! i would recommend eventually run another run of 1/0 and since that car is a unibody i would probably do a neg run. i would test with aero ports and u would need to make a port plug cuz ur gonna wanna have a pretty high freq for burp (mid 50's) and then ur regular freq for bass boxing. Just giving u some ideas

You will never get a really impessive score if you

1. don't own a meter

2. don't plan to build and test a few boxes

3. are willing to sacrifice some low extension and tune high.

The more impotant question is do you like the way it sounds? If you listen to it and it puts a smile on your face you did it right.
