  1. Future SMD build from ground up

    in Off Topic - Random, Misc posts - the forum "Junk Drawer"

    Posted

    If you could choose the make and model of Meade's next build, what would it be? You can choose anything. (car, truck, SUV, boat...)

    I think it would be cool to see him team up with someone that knows how to overhaul the fuck out of the engine while he installs the electronics. I'm not sure what vehicle I would choose but I'd like to see a piece of art. The best of the best from top to bottom. Kind of like Unique Whips but ten levels higher.

    A custom yacht build from ground up would be pretty fuckin sweet too.

  4. A few questions on building the best box for my ride

    in Subwoofers / Enclosures

    Posted · Edited by ATLien

    First of all what hx2s do u have, power or punch?? Next how much power do u plan on running if you're planning to replace the amp?? If not what model is that amp, so we can check the actual RMS ratings(which will still be wayy overrated).

    I have the punch series.

    Here are the specs for the subs. I'll be using two of these.

    # dual 4-ohm voice coils

    # CONsealer gasket hides mounting screws and prevents air leaks around the frame

    # frequency response 26-200 Hz

    # power range 150-500 watts RMS (250 watts per voice coil)

    # peak power 1,000 watts

    # sensitivity 88 dB SPL

    # top mount depth 5-13/16"

    # sealed box volume 0.8-4.0 cubic feet

    # ported box volume 1.75-4.0 cubic feet

    Here are the specs for the amp.

    # Max power 2-ohm 1000W x 2, RMS power 4-ohm 300W x 2

    # Max bridged power 4-ohm x 2000W x 1, signal-to-noise ratio > 102dB, THD 0.01%

    # Features remote subwoofer level control, tri-mode operation and bridgeable

    # 11 7/8" W x 2 5/8" H x 16 13"/16" L

    Right now I have the subs wired up at 4 ohms bridged according to Rockford's diagram.

    You think I should drop down to 2 ohms or leave it at 4?

  7. A few questions on building the best box for my ride

    Alright, I'll going to go with a ported box, subs facing up with port facing back.

    I have another question.

    Crutchfield says,

    Recommended Ported Box Volume: The ported box volume range recommended by Rockford Fosgate is 1.75 cu/ft to 4.0 cu/ft. Within this range, the ideal size recommended by Rockford Fosgate is 2.0 cu/ft, so this is the enclosure recommended by Crutchfield. One 4" diameter x 10-3/4" long port, tuned at 35Hz, should be used with a 2.0 cu/ft enclosure.

    I'm going to be using two 12" subs so obviously I need to double up on ct/ft for the box size but how does this affect the tuning of the port? Do I need to increase the size since more subs are used? I'm a little lost right here. How do I tune the box to 35hz when more subs are used?

    Also, how do I measure displacement?

    do subs up port back

    I'd like to know a little more as to why you would recommend the port facing back. Would that increase SPL or SQ? I just like to have a better understanding of why and how things work exactly.

    and get a better amp i am sure they will move a lot more that way

    I know Boss is a shitty brand but it's pumping 2000W max and I can't even turn the gain very high before the subs want to give out. (I wonder if this has something to do with my prefab Kicker box)

    and while youre at it, run some 0g and get a real 1000 watt amp and not a 600watt max piece of junk...garbage in, garbage out

    HAHA yeah I know man. I regret going to cheap on the amp. I'm new to all this and I'm doing all the installations myself. When I found this site I was like damn, these folks ride with REAL equipment! I'm learning man. And yes, the big three is up next.

    ps. it's 2000w max 1400 rms btw

    It sounds like the general census is to build my own box.

    I found the specs from RF so I'll do a little research and report back with a finished product. I'm usually pretty busy so it'll probably take me a few weeks to get the supplies and build something nice.

    Where can I find some good info on increasing SPL? I'm just starting out so I need to get my learn on.

    I just typed "how to increase SPL" in youtube and it came up with "how to increase your sperm count".

    here is my build so far.

    (just added pics and a video)

    Read the thread. The only time I mentioned SPL in that thread was when I said my goal is SPL but I would like it to sound good as well.

    Yeah these subs are great. They're a little old school but they will take a beating.

    My amp is the problem. It says it's 2 ohm stable but I know it's a cheap brand so I'm a little hesitant to drop it down to 2 ohms. I've heard a lot of people say not to go to 2 ohms with cheap equipment even though it says it's stable because it will shorten the life.

    I'm planning on doing the big three, replacing the head unit, adding (2) 6 1/2 speakers and (2) bottle caps in the front and the same for the back seats.

    I'm interested in building a new box as well but I don't know a damn thing about them. How much would you say it costs to build what my subs are rated for?

    edit: I'm a little drunk here and can't type for shit. :drunk:

    Whats up guys. I put in a little work over the last couple of days, took some pics and a video so I'll post them in a minute to show you what I'm working with here.

    So You have the specs already.

    I installed all my wires, mounted the amp, dropped the subs, and installed an intake.

    I don't trust my amp (Boss CX950) so I wired the subs up bridged at 4 ohms.

    This is still a work in progress.
