What kinda numbers do you think I can achieve with this setup? Car is an 06 Scion xB, currently I have stock battery up front, and a Kinetic 800 in back. Big 3 is done and dynamat everywhere so far but roof. Only cause I ran out of money. Box is 1.44 tuned to 38 hz sub up port to passenger side. Port is a single 4" aeroport. I made box so there is roughly 8 and a half inches to side of truck. 3/4" mdf except top plate top plate is two layers of 3/4. Box has lots of bracing. Just a note this is a version one of the nightshade. And is there anything I can try to gain a little bit more db's. Also, if it helps any head unit is a Pioneer Premier. Any help is greatly appreciated.

i also have a 06 scion xb. i am running 2 nightshade 12's and a 3500d. do not know what the scores with this setup will be but i can tell u tomorrow evening. other that that. i have had multiple setups in my toaster. all have been with an upgraded 170amp alternator from ohio gen. stinger 1/0 hyperflex, a 2400 and an 1800 kinetik, and 2 laters of fatmat on everything but the floor.

with one 15" fi btl and a memphis mojo 4k. the loudest i burped was a 145.2 @47hz. and 30 sec avg 144.6.

with 2 ma audio hk15x2 and a ma audio hk4000. burped a 148.0 @ 47 hz and 60 avg 145.8.

i will let you know tomorrow about what kind of scores i am putting up with this new setup.

152.4

152.4

Damn that exactly what I was thinking. But all kiding aside so many factors go into what numbers you can put up. It is virtually impossible to predict what you can/will do...

I was going to guess closer to 189.3dB. That shit will wang yo.

I guess I just gotta get it metered somewhere. But I do appreciate it everyone. I did ask a similar question to this when I first got my nightshade. People said I should do around a 140. But now that I got it all this way and I hear what its like I am thinking real hard about going alot bigger. Maybe two 12" Nightshades and a 3500. I will do my homework and see how much it'll cost me for bigger alternator, more batteries and more cable. I wanna be a bunch louder. But I know I won't do any other company then Sundown.
