So am I understanding this right a 300 watt Hawg-Wired System is 300 watts per channel 150 watts x 2 = 300 watts, and a 250 watt J&M Amp then be 125 watts x 2 = 250 Watts ?
Almost ... but the max Hawg system is 75 watts per channel and the J&M is 125w/channel when a 2ohm load is applied.
I need to correct my original post a bit first. I mentioned a home theater amp and stated it had 8 discrete channels. That was not accurate - I should have said it had 8 separate amplifiers. That is why (in my example) it is referred to as a "7.1 channel system". The ".1" channel is not really a discrete channel (although it usually has a separate amplifier) as it is the sub-woofer information. The reason it is not truely discrete is that the sub-frequencies are also in the LF and RF channels and are filtered out of those channels and sent to a separate amp section. So in a 7.1 HT setup ... there are 7 discrete channels and 8 amplifiers.
HawgWired sells two different amplifers. They sell a 60 watt and a 75 watt. They publish that they used the Root Mean Square (RMS) method of measuring power output so it readily comparable to other ampliers that state the output using the RMS method. HW is simply selling a single amp per speaker, but it is still a 60 watt or 75 watt per channel system. For 4 speakers, you need 4 75w amps for a total of 300 watts if all channels are driven to peak simultaneously.
The J&M amp looks exactly (and has the same specs) as my elfAudio - which is the same as the arcAudio, which is the same as Wetsounds, etc. J&M publishes there amp specs as follows:
"This is a full range class G amplifier and is spec’d at 125watts RMS per channel, both channels driven, continuous into a 2 ohm load @ 14.4vdc, 70watts RMS continuous into a 4 ohm load."
If you use their 7.25" speakers then it should be accurate to be 125w/channels as their 7.25" speakers have a 2 ohm nominal impedance. However, if you use other speakers at 4 ohm then the rated output drops to 70w/channel. Another option is to use 4 -ohm speakers and use 4 of them - hook the 2 for the left channel in parallel and hook the right 2 in parallel. This will drop the load to 2-ohms and the J&M will be back to 125w/channel. HOWEVER ... and this is IMPORTANT ... if you try and hook an additional set of 2-ohm speakers in parallel with the J&M amp it will cook the amp pretty easily as the total load per channel will drop to 1-ohm (a full short is 0-ohms). If you want to run 4 speakers (each speaker rated at 2-ohms) then the speakers MUST be wired in series rather than parallel - a total load of 4-ohms per channel will be realized, and the J&M rated output will drop to 70w/channel.
Anyway ... gotten far enough off-topic. Back to the 2011s!!
Have an Autumn Haze headed my way but don't have an estimated delivery yet ...
