How wild is your A/V setup?

Not that I'm going to break into anyone's bus, but how wild is your A/V setup?

Here's what I'm thinking:

I want to find a decently priced dual zone head unit (insert own joke here). There are some low end ones for less than $300. This would allow my wife and I to listen to music up front and the kids could watch a dvd or play on the PS2 while running down the road. The big benefit to this is that it would all be DC powered except the PS2. I also want to invest in a DC TV instead of an AC one. Back to the story...the downfall to these systems is that it only allows you to split the front/rear channels. So there would be two front speaker for music, two rear speakers for games/movies, and a subwoofer. When parked, all four speakers and sub could be made to produce whatever we wanted.

Speaker placement is something thing I'm not 100% sure about either. Ideally, I'd like to run 8 speakers plus a subwoofer; four channels in front, four channels in the rear plus a sub. I think it can be done using one of these dual zone head units, two passive equalizers (I have an old Sherwood XT-1101 that I can't wait to use again! I'd love another one!), and two-three amps. This would give me two separate zones with four channels in each, plus at least one sub.

Am I over analyzing things? Would it just be simpler to put a "standard" DIN size radio in with four speakers up front, then get a home unit for the rear? Actually, I'm sure it would be simpler, but I don't think that it would quite get me what I want...also, it would use a lot of inverted power. We'll be spending 14 hours or so on the road each month in travel time, so it would be nice to not have to mess with so much inverted power.

Feel free to shoot all kinds of holes in this! Actually, I'm trying to decide if I'm just crazy or what...nevermind. I know the answer to that too! Thanks for the input in advance.

Ben.

Re: How wild is your A/V setup?

We are going to use a 12 volt TV/DVD player like this, if not this one, we're going to be buying one soon.

For audio we have a Bose Wave that has the set up for an IPOD, but it's AC and I'm not excited about it, likely we will use an automotive stereo system with several speakers. I need to get this figured out pretty soon I'm about ready to panel the ceiling and need to get speaker wire pulled.

Take care,
Den

Re: How wild is your A/V setup?

I looked at that TV too. I think that (eventually) that's the one, or similar one that we'll go with too.

The entertainment system I looked at was an RCA-Wally World thing that was kinda like a Bose (not as good obviously) but had small speakers and a subwoofer. If all else fails, I may go with that. I think that route will be cheaper in the beginning...I don't know if it will be in the end.

Re: How wild is your A/V setup?

I'm looking more towards automotive audio because of the 12 volt capability thing. I've also heard concerns that home audio doesn't survive RV use all that well, I don't know if that extends to the Bose or not.

I'm glad you started this thread and look forward to hearing about what other folks have going on and how it's worked out for them.

Take care,
Den

Re: How wild is your A/V setup?

I've wondered, is it possible to hook up household speakers to a 12V car audio system, or car speakers to a household amplifier? Also, does household speakers in fact not hold up to the vibrations / temperatures of an RV? Car speakers can stay out in the cold / humidity / etc... I wonder as much for household speakers.

My Dad used a pair of Boston Acoustic computer speakers in his car for a long time with no trouble. They had a built-in amplifier and hooked up to a CD player's headphone out. It was easier for him than installing a new system. Then later, when he had to trade in his old truck for a new one, he just moved the unit.

Currently, Joni and I use our laptop for music and a couple of computer speakers. Right now we're along the lines of just use what you have, but I do still sometimes like to dream about what I don't have.

Shouldnt be a problem....same speakers really. Just make sure your ohm levels match up. Home speakers are 8 ohms usually and car speakers are 4 ohm. So you would need to hook up two home speakers for every 4 ohm line from the auto head unit (If you wire TWO 8-ohm speakers in PARALLEL, you'll bring the impedance down to 4 ohms). Also you should know that a higher resistance will put less strain on the headunit or amplifier and thus you will get less than the output rated. If you want to hook up car speakers through a home unit you wire them in series and it doubles it (turns a 4 ohm speakers into 8 ohm).


As for my a/v system. For the driver I am installing a set of 12 inch subs, cd player, 4 midrange 6 inch woofers, and two tweets. Sounds big, but I have the stuff sitting there so why not put em in. My real work is going into the living room area. Have a 19 inch lcd hd tv. Kenwood surrounds speakers. PS3. Ipod dock hooked in. Also a set of hard drives full of movies and dvds hooked up through the ps3. Also have it rigged up to receive from my laptop too. Should be a nice theatre. Haha....I like my movies.

Re: How wild is your A/V setup?

Well this my 2 cents.....Gen sets and power inverters are Not a computer or anything that uses a processor or circuit boards...friend UNLESS you buy a gen set or invertor that has a shin wav.(I think thats what you call it). Now the only reason I am telling this story is because...I own a wholesale company that sells heating and A/C. With this winter and power outages pepole has been hooking there furnace up to gen set when they lose power....(Why not right) Well the newer furnace today can not handle dirty voltage...We had a lot of units go down. Some of the unit where new and it cost the customer 6 or 7 hunderd bucks to get them working again. Just because of the gen set.....If anyone know more about this speak up..I finding out the hard way eveyone want me to warranty there unit......So I am thinking a PS2 or a newer TV would not handle it.

Re: How wild is your A/V setup?

what you were thinking of is called a sine-wave. if you look at the power created on an oscilloscope if goes up and down. a cheap genny and inverter can (doesn't have to, but could) dont look like smooth waves, but go up and down in a boxy look. real abrupt changes in power and voltage. a sine wave is a smooth up and down, the power doesnt make abrupt changes. the top one is a sine wave, the others are what a cheap inverter or genny could create:





couldnt agree more. you need a sine-wave inverter. they give you clean power that doesnt jump up and down in voltage. I run my system off of shore power most of the time. When I am not, I have an 1800 watt sine-wave inverter. I am hoping to pick up a honda genny this year too for those times I am not plugged in for more than a couple days.

Save money. Give the kids books.

I agree that life is easier if you don't have a mess of inverters and wires and stuff dangling off of you equipment.

Ben.
My initial reaction was that you're talking about using a lot of DC amps, but since your bus is running, it should be able to handle the DC load.

I'm similarly trying to figure out the best system for me. Most likely it will NOT include video. If I ever want to watch a DVD, I can use my laptop. That way I don't have to spend $$ on a screen that I then have to find a place for in my bus. But that's a personal preference.

For audio, I would like to have some kind of surround sound. My speaker placement will be 2 up front and 2 at the rear of the living area (basically at each end of the living area.) I want a radio only head unit with capability to play digital music (MP3, WMA, AAC) via external input (from my computer or a jump drive) and multiband equalization built in. It may be hard to find a radio only head unit that's any good. I don't really want a huge amount of sound power because that takes lots of electrical power: maybe something with 100W total among the four channels -- I just want to listen to my music, not feel it 100 feet away. I reckon that a 100W system would draw maybe 10 amps (total) at full power, and something like 4 or 5 amps at normal listening levels. That's an electrical expense I can afford.

Other things that I want: portable speakers that I can take outside and plug in to external jacks; some kind of subwoofer; and a decent retractable aerial so that I can get SIGNAL for radio.

Oh, and I want it cheap! LOL!
