you can buy just a 12volt power supply http://www.powersupplydepot.com/listitems.asp?dept=2&main=1 can also use a computer one to run a car amp or get a plat amp http://www.parts-express.com/pe/showdetl.cfm?Partnumber=300-750 and then you would need some kinda rca out, whether its from a receiver or dvd player and just plug it into your amp

Buy a real 120VAC amplifier and do it the right way, not these halfassed approaches.

There's more to a "home theater" than just subs, do you have any ideas for the rest of it?

so for a sub at around 500 rms would you recommend a plate or rack amp?

Imma prolly get some 6x9s and put them in a box... And use some old subs. But explain to me how do i power the plat amp and have it plugged to the tv

a surround sound or even stereo home theater receiver would be kinda essential in your situation tvs have sound outputs but going from tv to sub is going to be ******

You have a flat screen TV, yet are going to be using 6x9s in boxes with it?

have you installed anything before? car stereo or even a vcr? there should be audio inputs and outputs on all equipment.

get a receiver with a subwoofer output, hook that to the plate amp, hook plate amp to sub, use the front channels of the receiver for ghey *** 6x9's (really, thats a bad idea), hook tv to receiver, done

receiver = head unit
plate amp or rack amp = amp
ac outlet would be ur batt, just think of it that way

Hmm, ok give me something to motivate me.
Give me a tentative list and i will start saving up.
Is there something like a budget setup??

My bad. I should have explained better.
I am looking to buy a sub, set of speakers(lookin at 5.1), reciever and amp.
Budget was 500, will go up. Any recommendations on equipment?

this whole thing is a bad idea imo...just buy a receiver two floor stander and maybe a 8" or 10" Home theater sub.

I love Onkyo because I am using a 10 year old unit that keeps chugging and still sounds great. Even made a set of 5.1 Bose surround sound speakers sound better than with that atrocious Bose reciever. However, Bose made the sub setup super stupid (Power from reciever by stealing power from all 5 surround channels, wtf?!) so I'm in the market to build/buy a cheap 150-200 RMS solution.

As for using a car subwoofer for a home theatre setup, I am debating this route. reason being is that you can get some decent SQ subs for cheap, pair it with a decent plate amp and build a 3/4" MDF enclosure for a good deal and come out on top for power. SQ would hurt slightly, but the Surround reciever processor and plate amp should take care of alot of the sound quality anyhow, so I doubt many would tell the difference unless they got some really craptastic subs like Lanzar or Legacy.

Heck, I'd be willing to be an Alpine Type-S 10/12" would sound great for a fantastic price with a box and some filler. A 4 Ohm DVC wired to 8 Ohm would also slightly improve SQ though it'd reduce power output if you were working with a 4 Ohm plate amp, but they do sell them in 8 Ohm as well.

EDIT: Looking closer, the Type-S 12" has almost exactly the same specs as the JBL line of home theatre, http://www.google.com/products/catalog?q=ES250PBK&hl=en&cid=9744303857932005&os=tech-specs#p but they only give 80RMS (240 peak plate amp) in that unit. You'd have to buy a much nice plate amp and mod the box to pull out the true ability of that speaker, and it costs more money. A 200 RMS plate amp from parts express costs $150, a Home Depot piece of MDF is what, $30? You can get a 12" Type-S DVC in 4 ohm for $85. So for the same price plus some time and a friends (or your) tools, and $10 of hardware, you'd have a system with 3 times the power and nearly identical sound.

How can you tell which power supply matches your amp. Like I want to run my Digital designs 9512 in my house.

Clarify, assuming you mean my post?

What's the downside to getting 3x the power for your dollar with minimal SQ loss (assuming the 8 ohm load on a 200 RMS 8 ohm plate amp).

If you didn't mean me, then carry on :)

I could only imagine you would need to look at your car amplifiers limitations. It should be able to take a voltage between X volts and Y volts. Cars generally run between 13.8 and 14.4, but the amp maybe able to handle a 12 volt supply. Just check where the amp will cut out.

Assuming you meant using your car amplifier of course.

You won't be able to power any car amp with power supplies without spending more money than the 9512. Get a Dayton 1000w plate amp put the sub in a box bigger than spec.

thxsubwoofers

LOL, too bad inflation on the Dayton SA1000 went up :/. I remember it was in the mid $350 around. Now its at $425.
