How would I go about getting a computer sub put in my car? I don't have the cash for a sub and amp right now so I could atleast run this until later...

 

bump

 

sure

wont sound good tho

 

I'm guessing the sub has the amplifier built into it?

 

I've asked the same question before thinking it can be a possible money saver. I have an old but awesome computer subwoofer that was part of a 2.1 piece set. It's not possible to hookup a computer sub to a car radio and make it sound good. Computer subwoofers are only made for whatever set it comes with. Each computer sub is built to have a frequency to match all the speakers to make it sound good. If you hooked up a sub from a 2 piece set to a 5.1 surround sound speaker set it would sound all out of wack.

 

Most amps I have use have a setable LPF that would allow you to modify the frequency at which the sub responds. If you have a setable crossever, it would be easy to balance the sub methinks.

 

I'm sorry but lol. Just get a tubed woofers (bazooka tube style) with a built in amp, they are cheap and work decent. I have one in my beater and have no complaints.

 

I bought a Sound Ordnance B-8PT and it hits hard for an amplified 8". I got it on sale at crutchfield for 129.

 

Being that I'm in the process of putting something similar together...I can't guarantee what you'll have to do but with a basic electronics repair background I can help you get started.

Home audio, or computer audio, the enclosure is half of the reason a speaker sounds like it does. The enclosure is researched and designed to the highest degree to tune that speaker to sound its best at the right frequency. This does not mean you can't take the speaker out and build your own enclosure. You do however have to take the original measurements, angles, and design into consideration when buiding your own enclosure. so if the box that your computer sub is housed in measures out to say 1.2 cubic foot with a baffle somewhere, you need to build something that is meticulously 1.2 cubic foot with the same channeling and baffling as the orginal. you can build off of that to fit it where you want in the car and what not, or attach an amp rack to it so it gives you a mounting point to fit in the car but the speaker needs to be housed in 1.2 cubic foot of air space.

2nd of all home audio will have an impedance (resistance) of 8 ohms. Car audio is based off of 4 ohms. Therefor the wiring of this said speaker will be different then a typical car audio speaker. As far as wattage is concerned I have been told that you should find a power source that provides twice the power handling of the speaker at 4 ohms. So if your computer sub can handle 50w rms at 8 ohms you want its powersource (amp) to provide 100w @ 4ohm. Then you wire your terminals in the correct configuration to keep a 4 ohm load on that channel.

It's actually quite simple if you understand how power travels through the system to which I refer you to the12volt.com to brush up on.

If you go through with this setup please post up pictures and if you can a quick diagram of how to wired everything up. (you can do this in MSpaint)

I'm currently stripping my home theater surround sound speakers to incorporate them into my coupe. Enclosure design is the hard part. Good luck.

 

Take it apart find the speaker wire and disconnect it from the internal amp. Stick the box back together and run the wire outside the box. Connect those wires to a car audio amp or (ick) the deck.

That's the best way to "jerry rig" what your trying to do. Don't expect it to sound like it does in your house. A car is a much noisier environment with different acoustics. It will more then likely sound like poop.
