    burp box design needed will pay $

    ok, it looks like my project is off to a rough start, the next comp here is the first or next month (next friday) and i need someone to design me a burp box

    car was loudest at 45hz with 2 different sub setups

    box will be for a single fi bl fully loaded 15

    max height 15" max width 30" max depth 32"

    will be going in the trunk of a 95 grand am w/ no rear seat

    will be getting roughly 1400w rms

    luckily a friend is letting me borrow his amp for the comp.

    i'm not sure what other info is needed, let me know

    hmm you just want a ported box tuned to 45hz? what sub/port configuration? I could whip something up and get the ideas flowing.

    I could probably get you one for pretty cheap.

    Any idea what you want it tuned to?

    3 cubic feet 50" of port tuned to 45hz.. it'll fit turned around in any direction so you can play with firing the woofer in different directions. I didn't put it on there but i would do a double baffle w/ a flush mount.
    If your interested in all of the design pm me.

    also... you can try 45's in the enclosure if you'd like but i lost .4 db from adding 45's to the box in my truck.

    In a grand am I would tune more like 40 hertz. Remember do not tune to the car peak frequency, make the combination of box and car peak at 45 hertz.

    Re: burp box design needed will pay $

    i've found that vehicles are loudest when tuned to their resonant frequency. I'm tuned to 45 and burp @ 46.. i started tuned to 42 and every time i cut my ports down i gained.. going up 1 hert at a time.

    although, something may come into play with being underpowered that would make you want to tune lower.

    i wont be under-powered rms is 1300 watts loaded, i will be pushing 1400 so i will be 100w over rated daily power, i know its not insane power....but its the best i can do for now.

    what kinda wattage can i show these for burps anywho?

    its hard to say, in a burp application i'm sure the coil and all that can handle well over 1500 rms but i don't know if the suspension will hold up to that.
