My Windstar gains .4 taping the windshield and front vents but lost .13 when I taped the floor vents. When I opened them back up I got my gain right back. :cool:

did you see a difference in frequency? which way for you...up, down?

Unfortunately I didn't think about changing the frequency. That was just testing @ 47hz the whole time. I guess I should have done that, lol. :ohwell: I'll be doing it again...

always have the main vent system open to the outside....

small SS1-2 are very loud, even if you don't know much what you are doing 160 is not a big deal...

I guess eh Murilo I am trying to get to 160 probably with almost twice the cabin space with 2 18's. What amps and subs are you going to be running Bart?

Astros are not very good for SS1-2 with ported boxes, but with a BP they get fairly efficient, mine was doing 160dB with around 11kW at 56Hz.

Murilo contact me for the cookie

I have a pair of t3 t.s.n.s 15" and 4 ab 500.1 amps with 16v batts.....i dont intend to use 4 amps much though.

Here you go, one of my old cars hehe

160dB with 9kW and 2x 15s
