I've searched for this issue in the forum and could not find an existing thread handling the problem, if there is one please move this thread.

This is actually not a VW split bus issue or even a specific VW issue (installing a 12V stereo in a 6V vehicle) but I am curious and would highly appreciate if those of you that have installed 12V stereo equipment in your 6V cars could share the experiences you made. Both before and after the installation. The reason is because what is special for VW is that the battery is quite small (77Ah) which poses a challenge. (Maybe I am misinformed but I would think that a V8 requires a more powerful battery).

I have a slight hunch that this issue has been analysed and solved by many people having vintage cars and the need of a good stereo. So please, keep your points of view and experiences coming.

I would prefer (since this is what I am determined to do, I am not going to convert to 12V) the solutions in which the car's 6V battery is used as power source, not so much solutions installing an extra 12V battery.

Edit: spell.

another die-hard 6 volt fan, nice. i plan on installing a voltage inverter in my 6 volt bus. i will be powering a 12 volt cd-player and some 6inch/seperate tweets i have. so no amps, just something that sounds ok.
i do not want to deal with a seperate battery system or something that's overly complicated.

I recently installed one of these in my 6 volt bus and couldnt be happier.

http://www.6to12volt.com/

I dont have a stereo hooked up to it but have read it can handle a reasonably powered one. I did have a logitech portable boombox powered by it without any problems along with a couple phones, tablets and stuff like that.

btw, the logitech wireless boombox is awesome in the bus. Fits in the parcel tray perfectly, uses bluetooth (or a headphone jack) to get the audio signal from a smartphone or ipod. it gets surprisingly loud and sounds awesome. I found it to be the perfect combo for the bus.

Thanks for your reply.

Yes, I find it cool to keep the bus as a 6V the way it was designed even if it requires that all electrical components are kept top notch.

In regard to the stereo issue I suppose it all boils down to selecting among the stereos that consume up to a given Ampere level, that level given by the converter.

There are only two components that I would miss if I cannot run 12V in the bus: stereo and GPS. So I do not need a lot of Ampere...

Thank you for sharing this information.

I wonder:
Did you buy the negative or positive ground converter and what is the difference.

Btw psychoholica:

The bus I will be using the converter to is a 1964 Sea Blue 21W I believe is the same as the one in your avatar. Cool.

I've used the Motorola and Blaupunkt up-to-3-amp ones profusely in the past but lately I got the Meyers 8 amp. This is one trick unit and I've never been able to peg it. I have separate amps and head unit with a mono bass bridged amp all running on it. While it's on stereo I can still run accessories and a 110 volt cigarette lighter inverter.

If the wire from your battery to the frame is black and attached to the negative terminal of the battery, you have a negative ground system. Positive ground was a Lucas Electrics thing on British vehicles; they wanted the spark to jump toward the center electrode of the plug. No one else cared about the direction of the spark as long as it was hot enough to ignite the fuel.

I did have a positive ground '58 bug. It was unusual. Red cable to the frame.

Were the 3-amp ones producing a decent sound? I have no idea how many amps a modern small stereo requires but I am not lookin for some sound blaster, just a good sound at not-so-high volumes. OK, volume enough to overcome the air cooled engine, but then that's it.

Thanks. I did some googling and realized that positive ground was quite unusual. Appreciate your clarification.

One nice feat on the converter proposed by psychoholica is the 8 amp output current which, after doing some googling, is quite a lot.

I've found other converters on eBay, one of which delivers only 1.5 amp and "requires heat sink" according to the description. So I wonder, psychoholica, does the converter gets hot, or in other words, is it manufactured with a good heat dissipation feat?

Here's a typical up-to-3-amps type. They buzz a little but it's not bad. These will run what you want I'm sure.

No noticeable heat but then again im not powering a large stereo amp or anything like that. I've installed it with velcro to the front of the bus. I wasnt sure if this was going to be its permanent home so I didnt cut the wires short yet so it needs a little trim but you can see its size at least. The thing on top of it is a fuse I added for it. Dangling in front is a female cigarette lighter lighter plug with a dual USB plugged into it. This is the always on plug. I have another plug on the parcel tray which is attached to the switched output of the converter. You can also see the logitech boombox there too. Im tellin ya, the boombox is awesome. totally portable, crazy loud for its size and great tone. The 6to12 handles it perfectly.

It seems like an excelent solution. I have one similar in my 12V Westy only it does not have the USB outlets which make your adapter so awesome.

The up-to-3-amp converters seem to be quite common, I found a couple of them on ebay, didn't search a lot:



The nice feat by the converter indicated by psychoholica is to be up-tp-8-amp.

I am not overly technically savvy to answer this, but would like to know if there is an advantage/difference between connecting a 3-amp stereo to a 3-amp converter compared to connecting it to a up-to-8-amp converter. Is the second option better?

wow, that sounds interesting. So, the boombox is powerd by 12V which is coverted from 6V. Cool. I have a 66 Kombi, 12v but not interested in a big stereo gig, but this would work. Any chance you could send a pic of it in the parcel tray. Very Cool !!

If you look at the pic above you can see it in there. Theres a built in kickstand on the unit, you need to have that closed when you slide in into the tray on its side, then tilt it up, plug it in, and push the kickstand button and thats it! Theres rubber gripper feet which keeps your parcel tray scratch free and snuggly secures the speaker system.
What I really like is that its super portable. When plugged in it charges the battery so if you do something like camp out you just unplug it, take it out of the parcel tray and there ya go, portable boom box!
It also lets up to 5 devices to be paired with bluetooth so its easy to give control to the misses or whatever, you can also use a standard headphone jack to send tunes to the box if you dont have a bluetooth phone or ipod.
The included power supply as I mentioned is 12v so all i needed to do was buy a $.50 connector from Radio Shack that fit the power plug on the boombox. I made a cheapo cable out of some speaker wire and wired that directly into the 6 to 12 volt converter. The 12v feeds the box perfectly.

The absolute best part is the audio quality. Im still in disbelief when I turn it up as to how good it sounds. Cannot imagine a more perfect solution for our buses!

Hey Mark,
It pays to have an amazon warehouse about an hour away. I ordered mine yesterday after talking to you and had it today. Thanks for the tip! Bluemoon, here's a pic of mine that shows it a little better on the package tray. The silver blob in between the speakers is my 12v outlet. I'm going to move the outlet to under the headlight switch, cause right now the power wire for the outlet is a tight fit over the radio. The radio fits great. It's pretty thin, so you put it on it's side to slide it in the dash, and once you are in, you can stand it up. Like Mark said, it sounds great!
