if i was the op i would shoot for a common chamber 6 cubes box tuned 34-36hz and somewhere in the neighborhood of 90^2" of port. that would be a good all around box.

I gotcha man, and I definitely want to stay within the daily music listening relm.
What do you mean by I may only be seeing a few hundred watts? are you just refering to the impendence rise caused by the box?

Thanks for any advice!

Impedence curve is primarily a function of the electrical properties of the coil, but yeah... odds are you're not seeing anywhere close to 2500W at your peak frequency

i see 3 major problems.

1st port is too skinny and looks not to follow the 1-8 ratio and that causes probems

2nd not enough port area

3rd ur box needs to go 3-6" from the tailgate, ur wayyy to far away!

i hate when people compare burp numbers to 30second average on music numbers //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

that being said you should be doing better OP. but we all gotta start somewhere

Not necessairly there are people on Team Minnesota's Loudest doin 150's with two 12"s out of a trunk tuned in the 30's under 2000 watts clamped

ya, but they arent running the sa series. most of them run ns or zv1,2,and 3s.

Because that's totally the same thing as a pair of SA 15's in a Jeep....

We all know suv's are easier to get loud then trunk cars. He did it with two SA 12's well close enough it was a 149.9 with 2000 watts clamped over 2000 he was easily over a 150 I personally saw it. My point was that it's very possible to get 150's with his equipment.

I personally saw one of them doin 150's with two SA 12's in a trunk car and was at a 149.9 with 2000 clamped watts.

pretty sure they have more experience than op.

^^I would asume so, haha.

the ports are 19" by 1.5", which is about 28 in^2 of area. This being my first ported box I just went to a box calculator and started messing around with it.

Would you guys suggest aeroports over a slot style port again. If I went with a slot style port again I would try to make it as close to square as possible.

@SPLaudio I had no idea there was a target distance for ports to tail gate, thanks for the heads up.

@dbeez I am going to be building the boxes my self for sure, but I may have some one design one for me though and then just build it.
