using home amplifier for car

muddasirwaheedmalik · 28th September 2012, 01:37 PM

hi.
I have yamha B4 its 30W class A per channel . i want to use it in car.
I plan to use a 12V to 110V inverter to power the amp.
Is it a feasible option?
please advice

Yes.

Yes but. #1) if you mount it in the trunk it might get too hot on a hot summers day especially since it is running class A. #2 most home amplifiers are not designed for the vibration environment of a car and may become noisy, intermittent, or just stop working after a short period of time.
Your mileage may vary.

thanks ,
my question was in relation to car engine.ignition noise?
I suppose the car line is more noisy than mains.

Secondly i have wto yamaha B5 which is 200w into 8 ohm and 320 W into 4 ohm, which i believe is plenty for my front and rear components rated 4 ohm each,getting a decent car amplifier with equally good SQ would be a relative challenge hence this option/though?
Any comments on this approach?

if those amplifiers do not have a switch mode transformator then You have to use an inverter that has real sinewave output.
modified sine output inverter may work, or may damage your amplifiers.

Actualy it would cost a lot to get a real sine inverter that can handle high output powers.
might as well simply trash the original powersuppy of the amplifiers and make a swiitchmode one that has the output voltage/current capability to run Your devices.
