Can you safely plug a guitar amp into a car's 12V outlet somehow?

    Like if you wanted to play outside somewhere for fun...

    Are there adapters for this or am I dreaming?

    You need an 'inverter'...it converts 12VDC to 120VAC. Make sure you get one "big" enough handle the power. I would keep the engine running, or else you'd probably drain the battery quickly.

    Know that most cigarette lighters are fused for no more than about 15 amps. 15 amps X 12 Volts = 180 watts. Find out what the amp consumes in input watts, not output watts and you will get your answer. If your cigarette lighter is a 10 amp one, you only have 120 watts available for the inverter.

    And don't forget that the power your amp is rated at is only what is delivered by the amp itself to the load (speaker), not how much power you need out of the wall socket. Your actual usage in that case is significantly higher.

    You also need a pure sine wave inverter or the hum and noise will be unbearable. I have an RV with deep cycle batteries that will run a guitar amp pretty easily with the right inverter. Draws a lot less current than a coffee maker!!

    But yeah, in addition to the right inverter you'll need it to be connected to your battery with appropriately heavy wire.

    Yes you can do it.
    Your engine MUST run!

    Every other problem can be solved, you can install 2 batteries, 2 alternators, run heavy gauge wire to the battery an so on... if needed.
    (If you only power a 50 watt amp it can be as easy as buying a converter)
    The key is to use quality Inverter with plenty power to cover you safely.

    :D

    Risking my car's battery is not a good thing!

    I haven't been able to find it yet. I've got an 18 watt and an AC30...any idea what they are?


    Seems Monster Cable makes this one for $29: http://www.shoptronics.com/mopo300waduo.html

    Just use a small SS amp which draws less power or better yet a battery powered one like the Roland micro cube and play anywhere! Bob

    yeah but what if what I want to do is have a mobile gig, with 2 guitarists, each with 100 watt full stacks, so we can cruise through quiet neighborhoods and do drive-by rockings??

    I like where your head's at, man. You'll need a truck, a generator, and some sort of safety harnesses.
