Doesn't work that way. Depends on the amps internal design, and not on what its fed from.
It is imparative you find a speaker that can hold the ampage that a 350 watt amplifier can put out. It would be helpful if you went to your local music store or even car audio store. Its their job to help you.
Not much info in you question but Good Speakers connected to a 100 watt amplifier will improve the average sound system, speakers are the weakest link in the sound system so you should put most of your money there.
volts x amperes = watts so amperes = watts / volts X amperes = 700 watts / 12 volts = 58.33 amps Your amplifier draws 58.33 amps. This is assuming that your 700 watt number is actually based on power transferred to the speakers and is actually a number more applicable to lights or motors. Power moving through an amplifier changes up/down incredibly rapidly with the volume and frequency of the sound. That means that you may get 700 watts (and 58 amps), but only for a tiny fraction of a second. In addition an honest 700 Watt amplifier may only put 700 Watts through particular low resistance speakers (a 1 ohm or 2 ohm subwoofer for example where common speakers might be be 4 ohms and only receive half the power). Add that many low end manufacturers are notoriously 'optimistic' about their power levels and you have quite a mess.
Your amplifier has no 2 ohms output impedance. The output impedance will be smaller than 0.5 ohms. Put your subs in parallel. In audio we only use amplifier and loudpeaker bridging. Don't believe the myth of matching. Scroll down to related links and look at "Impedance bridging - Wikipedia".
Yes if it fits. The 40 watts would be an upper limit.
i just put the 600 watt e-plod 4-channel in my 91, its set behind the back seat and i built a cover for it with a piece of plywood, worksing great!!
You can safely put 48 regular (incandescent) 40 watt lights on a 20 amp circuit. If at some future date you might place higher wattage lights in the circuit, you will want to limit the number of lights to 20.
Yes. Lower wattage would be safe for the lamp wires and components.
There is no direct conversion . . . different types of lamp bulbs put out different amounts of light per watt.
The Watt hour efficiency is the ratio of the amount of energy available during the discharge of an accumulator to the amount of energy put in during charge.
You can, but it will not sound loudly. A microphone always needs a pre amplifier.
lumenicity (how much light something gives off) is not directly related to power. A 60 watt LED will give off more light than a 60 watt incandescent. You should check the manufacturers information. Light.com (first one to show up in my google search) specifies a 500 lumen 8 watt LED. the 52W incandescent "soft white" bulbs I have on many dimmers in my home put of 710 lumens as a comparison.
