Ok, finished with dinner and the garage and outside is cleaned up, so now its on TO THE NUMBERS!

Ok first off, I'll run down the equipment. A single SA-8 and a pair of mb quart 2000d's running at 2 ohms strapped. Box is a tommy k special. The note played for all the scores was 45 hz.

First up is a picture of the meters.

On the left is DC amperage draw for both amps, then AC amperage, then AC voltage.

Do the math and that ends up being 2816 watts. I DO NOT RECOMMEND THIS! This amount of power pushed the sub HARD, to the point where the cone hit the basket. But I'm doing maximum SPL tests so I don't care if I break something.

Now, for the NUMBERS!

First, since most people always want sealed on the dash numbers, even though my truck sucks ASS sealed up, here ya go:

Now things start to get interesting. MECA headrest style, door open:

On a side note, i did hit a 148.8 but didn't take a picture.

And, for the piece de la resistance, OUTLAW:

I will note that this is the FIRST box I have built for this sub, and literally did maybe an hour of testing and tuning to produce these scores. Give me a couple days and I can see things going up.

Hopefully I'll build a box for the pair soon and we can REALLY see what these little guys are capable of.
