when it sounds good i know for a fact that the gain is above the recommeded setting. i sounds good when i set it "properly" but it isnt as hard hitting as i want it. i can leave all settings at position as stated previously except when i turn the gain up i can get what i want. im sure its not the equipment...im happy with the equipment but in order to get it to sound the way i want i have to turn it up over the recommended gain settings. i just dont want to fry my $1000 worth of equipment, thats alot for me. lol

and i have no clue what db im hittin...no tools for sound..lol

if the sub isnt bottoming or going into severe distortion with the gain set where you like it then go with it..jl does recommended gain setting on there sub amps.. i have never been able to achieve good output using there method, always end up turning the gain up. music is sourced so many diff ways today that you need to have some gain overlap to make up for it.

that box is gigantic for a sa15.. 7cubes... sa15s can take plenty of power. seen a sa8 on a ns1.. lol
but your box is big enough for 2 sa15s. i helped build one for 2 sa15 that was 7.15 cubes

sa15 with a 1500, id do 3-3.5cubes tuned between 32-35hz

You may also want to play with the orientation of your subs/port. I built a box for 3 12s, subs up/ports up. It sounded good but didnt hit hard enough. I laid it down for subs/ports facing the rear & the difference was incredible!

 

[1LoudHoe]

usually with suv's and tahoes especially, subs up port rear is USUALLY the best overall setup.
get on a TL and see what setup is louder on a meter.
perhaps you need to do a mdf roof, expanding foam in the roof and some damping to the roof and hole truck

ok. sorry guys. i must have left out that i DO have 2 SA-15's.

If you disconnect one sub does it sound better? Maybe they are out of phase. Just a possibility
