Bump4life's and Slamminbeats DD9512 trunk scores!!!


Recommended Posts

This was the first time on the meter for both of us.

no tuning or anything, we both tuned by ear and went and TL the cars.

we both have DD 9512s unsealed trunks. firing forward with center ports.

Bump4life box specs:

4.96 cubes net after all displacement

tuning: 39 hz

peaked @ 42hz

9512s with f motors and i soft parts and new baskets.

I am using only a DD M1c (1200rms @12volts)

Sealed Scores:

38hz - 144.5

41hz - 144.9

42hz - 145.1 **loudest**

44hz - 144.8

Open unsealed scores:

28hz- 140.0

42hz - 146.1

Outlaw Style in Kick:

42hz - 145.4 (not sure if this is accurate, meter fell off when testing)

Music Open unsealed:

Aqua water - 145.4

Krazy (lil jon) - 145.8

Port Score:

42hz - 157.8

Updated TL Scores with DD M3a @ .5 ohm:

Sealed Legal Scores on Dash

146.1 @ 42 hz

145.3 on music- Krazy lil Jon

145.0 on music- Aqua Water gucci

Front windows down trunk open

147.2 @ 42 hz

146s all day on music on most songs with good bass

Kick panel outlaw style

148.7 @ 42hz

Port Score

164.1 @ 42hz

i dont think i clamped my amp correctly.

but i dropped to 12.2 volts and clamped 139.1. so around 1500-1600 rms? not sure if that is correct. the clamp meter was shop and i dont think was true rms and i used DC amps on power wire so that is not what it is outputting. so my amp takes in 139 amps which is pretty good if that is accurate.

Remember all these scores are with a trunk that is not sealed off!! and off stock 90A alt!!

Seal them fuckers up, and add some power :peepwall:

you already know more power is on its way ;)

and sealing will be last step. i want to see how loud i can get this thing unsealed.

as of right now, box slides forward and i can still access spare tire and my stock bat and all. i like to do that

NICE scores!

I have two 12's in an unsealed (for now) trunk with 2kW and these scores give me some hope.

Can't wait to meter mine and see where I'm at and go from there!
