Wiring Option Questions Sub and Amp

I am a pretty smart guy but trying to understand the differences in all the different ways to wire subs and then wire them to amps is very difficult to understand. I have 2-4 ohm subs dual voice coil and I would like to connect them to a 1500 watts mono channel amp in a way that both subs would get 1500 watts a piece from the amp. Is this possible? From what I can tell it is not. It should be but it isn't because if I wire them up in parallel it ends up being 1500 watts per sub but at 1 Ohm when connected to the amp which my amp doesn't support. If I wire them in series it ends up at 4 Ohms when connected to the amp which makes me loose half of the power down to 750 watts per sub so it is pointless to connect it that way. Am I missing something here or do I have it right?

the power will be split between the two subwoofers. 1500 watt amp with 2 subs ill be 750 watts per sub.


your two subs are not ideal for that amplifier. The best solution is for you to wire it at 4 ohms with the subs you have to get 750 watts, or 375 each. Otherwise buy a new amp that is 1 ohm stable, or new subs that are dual 2 ohm.

I thought that when you wired dual voice coil subs in parallel and either bridged them on a bridgeable amp or used a mono channel amp meaning in both cases both sub woofers where only using 1 channel that of course if your amp had enough power that it would give both subs the max power with that configuration. So my mono channel amp is rated at 1500 watts x 1 channel which would mean 1500 watts to both sub woofers. If it was a 1500 watt 2 channel amp and I connected one sub to one channel and the other sub to the second channel then it would split the power to 750 watts per sub. If that is not the case then what is the big deal about how things are wired if you can't get any advantage from one configuration over another? That's what I don't understand. It seems like no matter what you do or how you connect it your going to get the same result. What is the advantage of parallel over series or 2 Ohm over 4 Ohm if it all ends up giving the same power output? Doesn't make sense to me.
