Got Metered


Recommended Posts

  • 1 month later...

On the side, I want to try something...

142.6 db actual

91.5 db @ 1w/m (1meter=39.37 inches)

750 w/woofer

That is 71.3 db/woofer which is 21.2 db lower than what a single woofer made in testing.

Based on Chris Lewis's chart you should be hitting above 148.3 db

1500w= 3*5*10*10= 4.7+7+10+10=31.7

31.7 + 116.6 = 148.3

Can you measure the length from the dash to the box?

Ugh.

Please...stop.

Lewis' chart was based off the old dB meters, on which the OP would probably hit close to that 148. No way to tell without actually testing it though.

The only meter I can use is the new TL... Also this set up is gone now and has been replaced.

Rebuild coming soon

and his volts droppef to 10.2v, thats one almost in protection and two means ur score can only get higher

add another 3v here comes 144-45

alt first

big three/accessory battery in that order

I hope to get on the meter again soon. I have changed my stock battery to a powermaster d2400 and swapped out the dc 12s with Nightshade 15's. With big three and D2400 I am seeing as low as 12.8 now at full tilt. SAZ1500 at .5 which after rise is sitting around .8 on DMM.

Also added MLA Module

Rebuild coming soon

Monstrous failure.

You do know that it's not 71.3dB per woofer... doubling the cone area only gains you 3dB at best, in a totally theoretical situation. In most cases it's more like 2dB.

Back on topic, sort your voltage out and you'll gain bigtime. You're losing about 30% of your total power which should translate to at least 1dB, with nothing else changed.

10.x volts fo' life!

Did you bench charge the battery full before you installed it?

How lond did you run the car (audio off) before the test or tests?

With a single battery and a stock alt you will see around 13v or so while @ full tilt.

The only time it should drop like that is if your battery is drained and you are using the alt for all power.

Depending on your above answers charge the battery for a day or so get it topped off full. This will help your alternator with the module keep up. The module gives your alt the ability to produce the higher voltage but if your alternator just cant keep up the module will not over-ride the alts safety back off feature. If your battery is full you should see higher voltage. Always check your resting voltage before you do your TL testing. 13.3v @ rest is a good holding # for a new battery.

Check and let us know, MLA
