Question for you audio guru's....
I recently bought a Hogtunes 24.2 amp and 4 hogtunes speakers from another member. The speakers are rated at 5.75 Ohms and the amp is stable down to 2 Ohms. I have the two pair running in parallel to the upper fairing and lowers. With this set up each speaker is running at 2.875 Ohms [Zt = (Za x Zb) / (Za + Zb)] and therefore the amp is not functioning at full potential. I have a pair of 5.25" speakers from an old car audo set up where the impedence is 3 Ohms. My question is can I mix speakers of different impedence in parallel so long as I don't drop below the amp rating of 2 Ohms? Running one pair of the 5.75 Ohm speakers with the 3 Ohm speakers will give a resistence of 1.971 Ohms which I figure is close enough to the amp rating of 2 Ohms. I just don't know whether each speaker will get the same power or if the 3 Ohm speakers will get a higher output than the 5.75 Ohm speakers. Thanks.

Kind of late to ask questions. You already have everything, just hook it up and see if you like the sound. If you do then keep it, if not then change it. I think it is a good idea to keep all the ohms the same. The ohms are not going to change the output of the channel, if you have one channel that has to push through higher ohms than another channel there will be a chance of blowing the speakers of the lesser ohm channel. Just something to consider.

Just because the amp is stable down to 2 ohms don't mean ya ought to run it there. I wouldn't go under 2ohms at all. And yes, the 5.75ohm speakers will pull more watts than the 3ohm ones.

Why not post this question in the audio section. I'm certain you'll find the answers your looking for.

You can do exactly what you are speaking of, and you also are correct in that every speaker will only use the amount of power it had the load for, so if you put out 50w to that section then some speakers would use 20w while the others used 30w of the power, I have not looked at the speakers you used or done any math, so I did not give you numbers that correlate to anything you described, but I glanced over you post and know this is what you wanted to know.
Not something normally done though, because the amp will only produce a certain amount of power and on a bike the amp usually is not large enough to put out the amount of power to connect several speakers to. In auto applications, sometimes it is done with very large amp that produce a few thousand watts.
