Hi Guys
Im pretty new to this whole speaker/amp/watt/ohms game so if some of my terminology is wrong please forgive me :D. Basically my question is want to make sure that the speakers i have chosen for my home built speaker cabinet are suitable for the power amp that will be powering them.
First of all ill show you the power amp i will be using.
I am planning to buy a Alesis RA300 power amp
http://www.alesis.com/ra300
The rated output per channel are:
* 4 ohms: 150 watts RMS per channel
* 8 ohms: 90 watts RMS per channel
* 8 ohms: 300 watts RMS, bridged mode
Now the speakers i am planning to use with this amp are 2 Celestion Vintage 30.
The specs of the speakers are shown below:
Power Rating 60W
Nominal impedance 8Ω and 16Ω
Sensitivity 100dB
Now if i run 2 16Ω speakers in parallel the total ohms will be 8, is that correct?
Next if running speakers in parallel will that double the wattage, so will the power rating amount to 120W?
Will is be ok to run 120W and 8ohms worth of speakers off a 8 ohms 90 watts RMS per channel?
I look forward to a to hearing your opinions
