even with them down, it shakes to hell

running a 18 fi btl so im moving a large amount of air, its inevitable unfortunately

This guy knows his shit trust me o.o

If this guy is hitting close to 155db you can gaurantee windows down is just going to make it flex more I bet that thing is almost like paper haha

I wedged that little ass 1 by 2 in the spot and it solved the prob. I'm going to make something to fit and paint it up real slick

Yeah I hooked up some hcca's (friends) in my truck before he gout a vehicle and I stopped at a red light and rolled my windows up and my roof was flexing like three inches lol. My little 10's make it flex like 2. These roofs just suck imo

152 on burp or music?

burp iirc
it was years ago

but w/e it was i know its atleast .5 higher now with the amount of power i have added

I have another question as well

what would you think of adding a 2nd 18 fi btl to the truck if it has a slightly different magnet but same specs exactly
Its the one right before they went into the neo deneom magnets (n1) but the one right after gen 1 (triple stack)

i currently have triple stacked one, and want to build a wall with the 2nd fi btl that i already have, along with another ma4k amp, i just dont know if putting both these subs together even though they are virtually the same, is a good idea or not

and is that pic in your profile your setup?

If so n1, thats a slammer
Id love to hear that shit in person

what numbers you putting up ?

ya thats a nice score for a single btl nowall burp, dont mix magnets or each sub will have different motor force and sound fucked. i had the UFO motor btl years ago before i switched to the n2's and they sounded very different. If your gonna wall id it sell the ones you have now and buy a pair of n2's or sp4's.

Hmm true

Would you say the one im talking about puts better numbers up then the older triple stack?
