If you have two 150 RMS watt subs on the same ch of an amp What is the RMS watts needed from the amp?

Depends on the impedance of each speaker. If they are car subs and not converted home speakers, they are probably 4 Ohms each. Depending on how you wire them you get either 8 Ohms or 2 Ohms. 8 Ohms is not a problem load-wise for the amp, but if it is rated at 100 watts into 4 Ohms, then you will only get 50 watts into 8. Many car subs nowadays will handle a 2-Ohm load, but some will not. Your two speakers will handle 2x150 watts or 300 watts. An amp that is rated to drive 300 watts into 4 ohms will either deliver more like 500 watts into 2 Ohms, or it will melt through the floor of your car. So you need to look up the specs for your amp in the instruction manual. If it will only run into a 4-Ohm load, you can only use one 4-Ohm sub per channel. If it will handle a 2-Ohm load, you will have to turn it up slowly or you will blow your speakers out. Mr Ohm and his law will not be denied.

Is 4000 watt amp too much for two twelves subs?
Not if subs are rated for 2000 watts each.
I have 3 12 Q Power subs at 1500 watts a piece with a 2000 watt proacoustik amp will a 4000 watt pro acoustik amp push the 3 subs better and is Q Power a good brand of sub?
I have 2 q power 1500 watt subs and a 3500 watt proacoustic amp and it pushes it well although not enough so im sure you need more than 2000 watt to push 3 of them.
Can you use a 1000 watt amp and a 400 watt amp on 2 subs can they be wired together to give you 1400 watts for both subs?
no you can't. if you want to run separate amps for your subs they both have to be the same amperage and preferably same model. you can use the 1000 w amp on the subs and get a nice amount of bass depending on what size and model subs you have. then just use the 400 w amp for your mids and run the highs off the radio lines. try that and you will hear some good sounds. you will also need a crossover as well. hope that helped.
Can a 350 watt amp power 2 10inch subs 250 watts rms each?
depending on your amps rms, i wouldnt suggest it.
Can you run 2 subs with a 800 watt amp?
yes you can if each subwoofer is 400 watts (or very close) you can hook up multiple subs if it has more than one out put. hope this helps
How big of an amp do you need for two 1200 watt subwoofers?
Depends on what your willing to spend.. For two 1200 watt subs I would go with a 1200 watt amp and run both of then 600 watts ( you don't want to always run subs to full power, because the voice coil might blow or you will light your subs on fire). If your feeling brave you can run a 2000 watt amp 0_o that will annoy your neighbours, but make your car bump!
Can a 250 watt amp push 1300 watt subs?
In most cases, the speakers should be able to handle more watts than the amp can deliver. Doing it the other way around will blow out the speakers.
Why are watts called watts?
The watt unit is called after James Watt.
How can a 60 watt bulb use the same power as a 60 watt bulb can in a second?
Watts is Watts and has no relation to time. w=v*a (west Virginia varsity). A 60 watt light bulb is 60 watts regardless of how long it is on. Watt hours would be what PG&E bills you for.
How many milli-watts in a watt?
There are 1000 milli-watts in one watt.
Will a 1000 watt amp power two fosgate p3 12inch subs?
In a sense it would, say that 1000 watt amp was a mono channel. that would mean its 1000 watts RMS @ 1-0hm, 2 RF p3 4ohm would make it 500 watts to the two. if you want full power you need a 1200 watt amp @ 1-ohm, that would make it 600 watts to the 2 and that is the RMS of those subs. you can run more but running above RMS can blow or distort the subs.
I have 3200 watt sub woofers what amplifier should I get with how many watts output?
What's a subs? If you are consuming 3200 watts your amps at 120 volts will be 26.6, at 240 volts it will be 13.3. However I suspect I am missing some information.
