Well I figured it was about time to upgrade to a new plasma tv. I bought me a 65in Mitshubishi HDTV 1080p t.v. I love the t.v. it is very sharp picture and even playing a ps2 it has a much clearer picture than the old tv. Anyway my post here is about hooking up a subwoofer to it. I was just wondering if there is anyway of rigging something up to where you can hook a 10in subwoofer made for a vehicle to a t.v. without having to buy a sound system. The one thing that puzzles me is how to power the sub. I was wondering if there is anyway I can wire my sub up to my amp then splice the power wire from the amp and rig up a two or three pronged wall jack to plug into the wall to power the amp which would then power the sub? Just thinking outloud, I don't claim to be an electrician or anything. Not sure if you would be convering AC and DC electricity or not. Its not a big deal that i have to hook it up but i just still have my old 10 inch sub and a 200 watt amp down in the garage and was wondering if there was anyway of rigging it up to my t.v. Thanks for any input.

 

they do make a powered sub. i have a great 10" paradign sub that plugs
directly into an outlet and one wire to my reciever. if you have an out on your tv just get a powered sub. only about 3-500 or so depending on size and quality. you can go nuts and easily go over a grand, but that is overkill. if you use one made for a car you will probably need a converter also....

You can go to a place like Radio Shack and buy a power converter
Just watch for the right amperage.

 

So with a converter would my theory of running sub to amp, amp to t.v., amp to wall outlet work then?

 

why go thru all this trouble when you can get a powered home amp?

Because I don't necessarly need to do this. I don't "want" a home theater system. I was just wondering if i could put my old sub and amp to any better use rather than collecting dust in the basement. Thats all. I was just seeing if it would work or not. If it doesn't, that's fine I'll leave it downstairs and try to sell it or something. If the theory does work then why not put it to good use. You know what I'm getting at?

 

the power for the sub would come from the converter. The signal would come from the amp.
I haven't done this type of work in a while. But the Speaker power from the battery of the car, goes to the speaker, right?
So the converter would be that power wire. But like I stated. You will need to look to make sure the converter has enough amperage.

 

Alright if I remeber correctly when I had this sub and amp wired up in my truck I still had the stock cd player. Well I'm almost certain we wired it like this:

Not sure if this helps?
I'm at a loss right now. Its probably more work than what the reward is worth.

 

It's not the ac/dc issue as much as it's the issue with the fact that most car speakers are 4ohms while home systems push 8 or 16. Some home theater systems can accept this issue. I'd check on your home amp to see what it can accept because running 4 ohm speakers on an amp that can deal with that fluctuation can burn the amp.

Edit...
Oh, I see you wanted to also use your car amp. Then yea, you'd want a converter like previously mentioned. It's probably more trouble than it's worth in that case honestly. You'd need an ac to dc converter to power the amp, then you could run things normally. Signal from your source to the amp, then run your amp signal to your speaker(s). Pretty simple actually, just probably easier and cleaner to buy home theater stuff.

 

I recommend this:

They have one or two at most Radioshack's across America.

It fully cleans the power too, so there is NO electrical noise.

 

I found a 'Sound Bar' by Boston Acoustics that includes a wireless 6" sub. The sub is powered and simply needs an AC outlet. No wires to the TV and you can put it anywhere in the room. Overall, the sub is less than 12" cubed.
The 'Sound Bar' is about 31" wide and 4" high and 4" deep (approximately). it gets placed under your TV or on the wall. Cost is about $300 at Circuit City.
I have not yet bought it. So far, I see a lot of good reviews.
