DB estimation? audio experts help


Recommended Posts

Posted

Hey guys,

I'm wondering if anyone has ever metered two JBL P1222's or P1224's and what the results were. I am looking to upgrade from my two JBL GTO 1214D subs to two P1222 Bad boys and instead of using a crappy pre-fab box like I have now, I will build a box facing into the cabin and seal it all off from the trunk. Car is a chevy Cobalt Coupe. If you guys could use your super power skillz and estimate DB's this upgrade would give me I'd be forever greatful :D

Amp is 1550RMS clarion.

There is way to many varibles for someone to tell you...

Me metering those subs in my jeep is going to have a very different out come if they was metered in your cobalt.

Yeah, I figured these answers would come out. I was just wondering if anyone had any IDEA of how much these subs could meter at...I don't care if it's a different car or enclosure, I'm just really wondering what the subs are capable of. I know that I have optimal box designing to do, which i will get to at a later date. I don't actually have the subs yet, I'm just considering upgrading to them, that's why I'm asking. thanks!

it cant be done, unless its a funky pup

than the answer is 2000 deebeez

hahah another funky pup joke...wow.

ok lets make it real simple...does anyone on here HAVE 2 P1222's?

if so, any idea of DB's YOUR SETUP is giving with these? that's it.....it's all I want...AAAAH!

Anyways I just downloaded Torres' box calculator, gonna start looking at best box design which will face into cabin, with a port. Any suggestions would be cool.

Considering this is your first box I would guess a 129.7 8)
