I know, but isnt a ported box kinda lacking in the higher notes too? Like around 60-100hz. Book says my subs need 3 - 4" x 12.5" Ports each tuned at 40hz, so thats alot of ports to **** with, and i have no idea how to do square ports either //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif. Ive only heard a few ported setups, and they were loud. id like to try ported but its complicated and i dont wanna mess anything up. Ive heard theres alot of complications with a trunk car on where to place the ports and whatnot //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif But Im very impressed with the output of these so ive decided im gonna stick with them until i get more money to play with. Louder than my friends camaro with 2 type Rs/sealed on a p1000 and he has more power.//content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif Cheap and sound good too

It depends what you tune your ports to but hopefully you have your car speakers handling much about 75hz or so

I have a trunk car and my ported box is fine

Whats the price on 4 inch pvc? Im gonna need roughly 9 ft 9 inches of it to do ports. How much airspace does a 4x12.5 inch port take up? Unless i do square ports, which would probably be cheaper and easier. Book says i need 37 inches of port area, and 12.5 length so with 3 subs how do i do that math. If i can get the design of the port figured out i know i can make it, its just the math thats killing me.

if you're getting the crunch gp1500d, i don't belive it'll put out close to 1500 watts, i think its more like 750-800 watts

from reviews ive read it does a good 1500wrms atleast if not more. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Edit...shit. Just found out these were rated at max power not RMS but the stupid **** sites say RMS power...wtf. Good thing my order hasnt been shipped yet. I must be thinking about the 3000d that does 1500wrms. Oh well though. What do you guys think about an M1000 amp? Supposed to do 1000@2 ohms, and has 4 25a fuses so im thinking it does atleast 1000, and that was my backup choice
