They are not cheap at a PC Richards etc.

Can you Make your own Powered Subwoofer?


I am thinking if you had a Car AMP and AC converted to DC and a good box,speaker would it work? Will you always here a humming?

To your original question, I did that once. I was a DJ in a prior life and built an 18" subwoofer to use for my gigs. I still have it, but now I use a conventional 120vac subwoofer amp. Anyhow I got a Rockford-Fosgate 600W (bridged) amp and ran it off of a battery and battery charger until the battery gave out. Worked for about 4 years. I tried a power supply, but the problem you run into is the power supply will not have the surge capacity to supply the amp when a hard bass note or explosion sound occurs.... in otherwords there is no headroom without the battery and it sounds just ok, but not dynamic.

Now if you are going to do this using one of those big sub amps, be sure and get a quality driver. The best results, imo, is to get an 18" driver with a cast frame. No sheetmetal stamped frames. Put it in an approprate sized box and it will rock. Nothing like moving a lot of air when it comes to explosions. A smaller sub just can't compare..... Well except for the 2700 Watt Powered Sunfire by Carver. That one rocks too. And at about a grand or so (with smart shopping) is not much more expensive than building your own.

The bigger the Box the heaver.

I am going to make my own Box.

Where is the best place to Find a good crossover?

Is a digital better that the old passive ones?

Most subwoofer amps have the crossover built in. The 1000W job on the site you referenced has a 30-200Hz adjustable crossover built into it, so an additional crossover won't be necessary. That and the fact that most any of the x.1 equipment subwoofer output will already be crossed over.
