i've got a couple of jl 12's that used to be in my car before i decided it was time to upgrade.

wanted to know the most cost effective way to use the car subs for my room. i'm likely going to sell the system soon, so i'm not really looking to spend very much money.

and i know car subs are meant for cars and not homes, but idrc. i just wanted to experiment a little bit and wondered the best way to do this.

thanks

Just say no to Ground Pounder Customs.

some cars do over 170db with one sub, so clearly my two 12"s can do that in my car, with my knowledge too! look out bitches!

you can either use a car battery charger and attach it to a battery as Bassick statedm or you can buy a computer power supply (preferably over 1000w) and attach all the yellow 12+v wires to the amplifiers 12v+ and the adjacent black wires for ground, to the amplifiers ground terminal respectively. then find the large 20 or 24 pin connector and find the green wire and the adjacent black wire and find a way to attach them together, either a paper clip (not really safe lol) or cut them off and solder them together etc. this will simulate the computer turning on and it will kick on the PSU. then take a short piece of wire and bridge the 12v+ and remote terminals on the amplifier.

Lol overpriced amp huh. Shows how much you know. I know folks. Dont be mad you run a piece of shit amp. You and all the other dont know bbetters can say man itd awesome its awesome and I got it for 125 bucks. Ive spent more on glue.

Clip city bitch, clip clip city bitch. 10's, 12's, 15's, goin up in flames bitch.

If I were to go that I would use a computer PSU. However, I have to agree with dolarbilz on just getting an amp that is designed to work off of 110v.

Just my opinion on this. I have a 750w computer power supply that i bought a long time ago for a damn good price of $40 when circuit city was going under. It works great for mine but it by no means has the amperage behind it to keep my amp powered on for my sub. I have it running my old fusion reactor ream-900 amplifier and it is a pretty decent amp from what i use it for but i have to have the resistance up higher than hell or else it draws a lot of current and my psu i have goes into protect mode due to it being overloaded. So as a precaution dont expect to crank out the same power you can in your vehicle by using a power supply. it just wont happen.

And Kranny im not trying to say you were wrong at all but you dont need to take all the positive and grounds to the amp. I would just say that if possible make the runs as short as possible because as we all know the 12/16 gauge wire that the power supplies come with is not enough for running a car amp. I had mine on the stock 3 foot run (yea thats right a 3 foot run of the stock power supply cable!!!) and the end of the wire closest to the amp got pretty warm from it being loaded up with a ton of power. The PSU will get you going but if you expect to wire your speakers up in a very low impedance or crank the power dont expect it to stay on. Either you will fry your power supply or you will make the power supply go into protect mode like mine does and you have to reset it by pulling the plug from the wall for 5 minutes.

i'm actually only using a 500 watt amp. don't need a tonna power. i just wanna see if it will work, and play around with it a bit.

i've got the W0v2's. spent waaay too much for the system.

anyways as long as i can get like 100-200 watts going, i'll be happy.

yea my amp is only like 250w rms at 2 ohms and when i wire to 2 ohms i can get it to sound good but when i start to raise the volume it draws so much current it shuts off the power supply from it being overloaded. So you can do it but just be warned that you will more than likely overload the powersupply and make it go into protect mode or melt it.

does that really works? pics please.

anyway what i did i had a regular home surround sound that i had laying around collecting dust, it came with on 8 inch sub with about 150w of power. i tore the box that the 8 inch came in and hacked into the power supply, took it out the box and attached it to my 10 inch jlw7 and i must say for the 150w that im getting is 100 times better and sounds great.

honestly i think that its a load of crap that you can run a good amp off a wall charger. Most wall chargers run on mili-amps (spelling) so you cannot possibly get a decent amp powered by it without melting the wall charger. If you want to run the amp off a wall charger then by all means go for it but im sure it will melt your wall charger and make a fire but hey, if you want to lose your house then go for it.

i started my system off a 6amp charger and a little batcap battery. it worked fine for mids and highs but when i added the sub amp it just took too much power so i used a 12amp charger and the thing threw out 16v all of a sudden so I took that off immediately. then I went for a power supply and its working great. its not a computer power supply, its for a server i believe. you could probably find some really cheap at an electronics surplus store or something. and they are made to run 24/7 so they should be higher quality than the cheap computer power supply.

the down side to these is that they have small high RPM fans that are pretty loud. on mine, I just took the fan out and put in a quieter, slower fan. it's working fine, doesn't get hot, just a little warm.

I agree to this !!!
At least call the fire department before you hook this up and you start this process ...
My amp can pull about 50 amps on an astron power supply (and thats my mids and highs amp !!!) ... not even gonna mention what my sub amp can do ... and both of these amps are class a/b ... and your trying to hook up a class d on a wall charger ??? thats insane !!!
I stick firmly (as certified Electronics Technician and as a certified Cable Television electrical Lineman) to find a Astron Power Supply to run a car audio amp or get a Home Stereo Amp setup ...
Just my suggestion here ... thanks, Randal ...

In case this question is still actual, Corsair AX1200, for example, can do 100 amps on +12V rail. But it's far from "cheapest", on newegg it's around $280. Alternatives might be OCZ ZX1250W (104A on +12V) and Silverstone ST1200-G (100A on +12V).
