    Cooling with a subwoofer

    My truck has no center console so i was going to build a center console/case/sub enclosore for my car pc heres a rough idea
    Would the sub provide addiquite cooling. am i worried to much about keeping it cool? plexi glass would be cool but out of my budget. any ideas? i have been reading alot about this and i thing im gonna put some money into this. just want a second opinion.

    I highly doubt your sub will be able to move enough air. Depending on your hardware you might not need to worry about cooling too much. Otherwise 2 fans should do it, 1 taking in air and the other pulling out.

    Not only that, your components aren't going to respond very well to the vibration induced by the sub...........

    As in, longevity.......

    A sub doesnt really blow or suck air like a fan. The sub only makes the air vibrate, hence air is being blown by the sub, then sucked back at whatever frequency that is being played. I doubt you will notice any temperature differences even when your sub is at loud volumes. Why not just install a fan?

    I believe some subs with ports actually have a heatsink next to the port, where the port cools the heatsink somewhat. There is actually a patent on this design.

    I have seen some powered pro audio subwoofers using a similar design. The amplifier module (complete with a large heatsink) sits in the port opening. When you are in front of large systems like that it does feel like a fan. Remember that these systems usually use 15" or 18" woofers with about 300 to 2000 wrms depending on the system.

    Car audio amps are made to handle alot of vibration but the amp needs to be mounted correctly. Off the top of my head I can't remember which direction it is sopposed to be mounted in relation to the sub. I definetly would not recommend mounting a computer in the sub port.

    I've always read that mounting an amp on a sub box is bad, but people do it all the time. I seriously doubt your computer is going to enjoy being directly linked to the vibration of the sub. It's a recipe for hard drive failure, at least.

    true i thought about the vibrations after i posted. two fans is a simple solution. I have very limited space 91' Chevy s10. I wanted to build a center console and install a sub. I trying to keep it low budget using old pc i was going to mod with a new PSU, build enclosure. am i setting myself up for faliure? i want to order my lilliput and see how well the set up could work

    thanks for all the support

    Oh yeah they all start off low budget.... sigh. Sure I'll piece together a computer from spare parts... soon I've spent $700 and want more more more!!

    Look for other places you can mount/stuff your computer, try to hack a computer case to make it smaller, stuff like that. With a little creativity (and perhaps a little $$ investment) you can get it all to fit nicely.

    yeah i have done some fiberglass work before theres no problem with making the thing just finding the right place. i was doing some measuring today and i think i can get it to work right were my head unit is now plus the ash tray under it (that i never use) are you glad you spent the money on it? My buddy says if i can get mine to look good he will pay me to do it to his ride. do you have any "gosh wish i would have thought of that before" and i noticed you used a 7" screen. I have a tape measure and it seems pretty small. any functionality problems with a 7?

    Thanks for insight every one
