I want to build a subwoofer

post #1 of 4
Thread Starter 
I want to build my own sub for my computer. something that will blast your pants off. However I need to get an amp that will push at least two subs. my problem is I do not know where to get a cost effective amp. However, some car amps seem to be really cheap.

therefore,

Can I use a car amp and get the same results?
Is there a way to get a 12v dc current to a car amp?

Help anyone
Thanks

Your better off buying one already made with an amp built in. Reason i say this is, to power a decent amp will take a hefty 12 volt power supply , which will cost more than the amplifier and speakers.

And to do the job right , you want more amplifier than speaker. So you have lots of headroom. And like i said earlier. To power a good car amp will take some juice and 12 volt power supplys with alot of amperage are not cheap.

you'd need a dc converter that has a Positive +, Negative -, and a Grounding Wire. Your amp won't turn on without it....


You'll also need a way to get the audio signal from your headphone jack to a RCA input...You can find one of those at radio shack

First off, don't go with a car amp and power inverter. Get a home theater sub amp that's made to run off 120 VAC from your wall. You won't have to get some sort of extra power supply, and the you'll have an amp that's made for your purpose. Take a look here:

I have the Adire 250W (RMS, 400W max) which is basically the exact same as the 250W PE model. Works fantastic and plenty of room to work with. Using this amp couple with a single 12 or 15" sub will be more than adequate for a PC, or home theater for that matter.
