Stereo? 110vac home or 12vdc mobile?

Do you have two separate systems in your bus so you can have a 110vac tv and sound system along with the 12vdc car system when driving? Or do you use one or the other and buy the tv to match?

I'd like to run a home system only on an inverter, but dont know the ins and outs of antenna hook up.

Mobile stuff is going to be easier to install. Another thing to take into account is that many home electronics have an internal AC-DC converter in them. AC power has historically been easier to transmit over distances so that's been why its been used.

So I wish I could tell you from experience, but only conceptual understanding. Bus on/ or bus off, you probably want as much running off 12v DC car system as possible. Unless maybe if you plan to be plugged into an AC grid most of the time. Since TV's, laptops, USB outlets and apparently stereo's too (according to Stewzer) all are powered by DC (converted from the AC in your outlet). It is within your best interest to power them directly from DC (maybe with a dc-dc converter). Otherwise you will face inefficiency from Inverting DC->AC->DC.

I would use car audio stuff at least when moving, has much better electrical interference shielding than home audio equipment

Now that's interesting. Thanks for the new info.

You may want to check in to some of the more capable "chip amp" systems used for automobiles by audiophile tinkerers. Diyaudio.com has a lot of interesting content about them.

They often run on higher DC voltages, but a simple dc-dc power supply can raise your standard 12v system to the 24, 30, etc. (or even a split rail supply) that an amp requires without incurring the loss of an inverter. A proper isolating dc supply will minimize electrical noise.

Of course, it's possible to just buy a class D amp from car audio places and avoid all that mucking about... Heh. I have a weakness for reinventing wheels.

Yep...going with a DCV system is much more efficient, power-wise...and built for the vibrations of the road
