So what added that .7 db?

During the long trip home I was thinking about that.

Possible things it could have been..

No trim rings

I left the batteries on charge all night.. plus the drive down to the show

Raised the front of the box (which never worked before)

Cut the power wires shorter.

Adjust the amp and radio how Rich told me too...

Actually left the seat straight up...

Not sure which of these things did what...

I really think it was from Jacob changing the intake manifold bearings....

Really?

I gained .8 By changing blinker fluid.

Another .9 Via the muffler bearings.

Oh yeah, those muffler bearings go bad quick....

Don't forget to check your headlight fluid.

those 2 make big differences. raising box and seat thing redirect bass waves coulda helped. As far as the batteries I hope you always charge before a show! LOL
