Stereo advice?

I am going to use a computer for a media center and internet platform in my bus. My brother is donating a computer that he is going to put together (he's a computer whiz -- works with DNA sequencers and stuff, and wrote what was once the most popular free-ware e-mail anonymizing program in the world.)

I have a Soundblaster Gold soundcard, that's not the latest thing, but is good quality. The video card will be donated, so I don't know what it will be. Eventually I may put some kind of TV/Video production card in it. I need to get a GOOD RF card, because I mostly listen to a local bluegrass station, and my current clock radio won't even pick up the local repeater for that station...and it's located within 25 miles! Grrrr...

I'm stumped on how to go with speakers. If I recall, car speakers are a different impedence from home speakers. I would prefer to mount the speakers permanently, but can't decide where. Over the driver's area would look good, but how would it be accoustically? (Listen to me....worrying about accoustics in a sheet-metal school bus! HA!) I will feed some kind of amplifier from the computer output, and then the speakers from there. What kind of speakers and amp should I get, car equipment or home equipment? I'd like to have 4 speakers in the front of the bus, and maybe two in the back (thinking in terms of car speakers), and maybe a small sub-woofer somewhere (low frequency, doesn't matter much where it goes --- see sound deadening experiment post).

Any suggestions?

Oh, yeah, and of course, money IS a consideration...

Here's what I did:



The receiver and speakers came from the trash and the receiver works well from the 1500 watt inverter (but not so well from an older 300 watt inverter). I haven't tried it on the road yet.

Impedance is only a problem if it's lower then what the amp is rated for. If the amp is built for 8 ohm speakers and you connect 4 ohm speakers you can melt the amps output, but really only if you crank it, for most practical listening situations (assuming you're not some crazed metal-head) you'll be able to run into 4 ohm speakers with no problem.

Still lots to figure out

Hmmm... Nice set-up in the forward overhead compartment. Boy, do I wish I had a window like that. I have a panel, but no glass in the front. There is a security camera box mounted in it that will have to go sometime. I doubt that the security camera is still inside. I am going to take the panel out and use the space since the security camera mounting ruined the panel for leaving it blank.

I'm going to cruise the thrift shops and see if I can find some stereo speakers. My babysmamma wouldn't mind if I took our home stereo, but those speakers are too big, and so is the amp and receiver (which is why I'm going to use a computer.)

You should permanently mount your speakers and connect them to an amplifier. Then you can easily connect the computer to the amp using a sterio mini plug to RCA adapter cable.

I have a rockford fosgate car amp connected to 2 bose home stereo speakers, it rocks.
I use an Ipod connected directly to the amplifier to play music.

Amps and Speakers

I went to Circuit City tonight and looked at amps and speakers, and I need to do more research. I'm just confused.

I haven't done that yet as I consider that WAY down the road for TCD. Nevertheless, I do want a nice sound system for my wheels. I'm not so much a TV watcher as I am a lover of music. My thought is to rig up two sets of speakers for front and back near the same spot the old speakers were.

A BOSE system would be most excellent. Even the little set ups sound like huge system.

I am planning on doing a computer surround sound system real soon. I'll be using 7.1 surround computer speakers powered by a pretty good soundcard in the computer. Havn't picked either out yet.

My question to everyone is about how to power my computer. The speakers will have to run off 110V, but the computer is natively 12V. Thus the purpos of a power supply is to turn 110 down to 12 so the computer components can run. But it's pretty pointless to go from 12V Battery bank up to 110 through an inverter then back down to 12 through a computer power supply.

So, does anyone know of a computer power supply out there that is powered from 12V rather than 110?

They're doing it in those damn rice rockets, but maybe they are hotwireing the computer. I'd like to stay away from that and get a product if possible... Do I make any sense? Any ideas???

This is on my hotlist too. I agree, 12vdc->110vac->12vdc seems kinda silly.
I plan on doing research soon & will post what I find.
Thx for the reminder.
