car amp for home stereo
no offense or anything, but that most illogical thing i've heard....
why not take advantage of the higher voltage levels of the alternating current setup?
use an amp built to take that kind of voltage....like a home theater amp, or pro sound reinforcement amp if you want more pound for pound performance!

I've heard of people using a power supply out of a computer as a AC/DC converter for 12VDC audio amps. I dunno how good those work though. I bet that computer power supply is really struggling.
I was always wondering, where could i get a household amp? I've been toying with building a powered sub for the receiver's sub pre-out just so I could get some massive lows [IMG]i/expressions/face-icon-small-tongue.gif[/IMG] Where could i get an amp that take AC current andwhat would i need to do to mak eit work? I've seen sites where they make the sub boxes and have just regular amps. thanks!!!

to power a car amp in your home, you have 2 choices. #1, get a power supply, #2 get a battery.
#1. the power supply is by far teh best way, but very expensive. I bought mine retail for about $250, it is rated for 40 amps. This is why you cannot use yoru cell phone charger or a computer PSU. sure its 12 volts, but like 750 milliamps. your amplifier will draw some heavy current! 10 amp supplies (good for 100 watt amp or so) are $99 at radioshack. you can get them cheaper online, or REALLY cheap at ham radio trade shows. thats what I would look into if you want a good supply thats really powerful for really cheap.
#2 a battery. a car battery of course, and if you care about hydrogen emissions and all teh other great stuff a regular battery emits into teh atmosphere during normal use, then you will need a jail cell battery (aka marine battery, aka yellowtop, aka sealed battery) the advantage to this method is you are first of all not limited to current caps, my 40 amp supply even at 100% efficiency can only generate max 480 rms watts of power from any amp. A battery will provide ALL the current your amp wants (even 3000+ watt amps) It will also be far cheaper, as you may have batteries and other equipment we are about to go into lying around.
the one problem is of course, your battery will die. You will need a charger to keep the battery up. Keep in mind that chargers ive seen (that are inexpensive) are 2 amp supplies, therefore the chance is that if you have high current amp(s), even with a charger, after 5 minutes of music (much less a movie) your amp will crap out since the battery will be dead.
there are disadvantages to each, to be sure, you just have to decide which is better for you, if you decide to go ahead trying this.
and for anyone that is really curious, I have a TrippLite PR-40, it weighs more than double my JBL1200.1, more than my 15" tempest did, and is about 10x12x7 inches in size.
