2 ch amp with dual 2 ohm sub

I just got a 2 ch amp that runs 300 watts max rms at 2 ohm stable resistance. And a 10" Alpine Type S dual 2ohm sub that runs 500Watt rms with 900Watt Peak. so i was wondering if i wire the sub in parrallel or series? if anyone has knows wt i should do plz reply.


Thanks

PS The amp is Axis3 and i got it for free without a manuel so if anyone has the same amp plz send me a copy.

you could series the coils to get a 4 ohm load bridged.
or you could run 1 coil per channel of the amp.
see which sounds better and which you want to keep.

You're safer to series both coils and bridge the amp. You don't want to put stereo into 2 different coils. Anything different or opposite will create heat.

You also used max and rms in the same sentence. They are definately 2 different things. If that amp is 300 rms, it will work ok with a 500 rms sub, but won't really be loud enough for most of us.
If that amp is 300 max, use it as a paper weight.

Thanks for the input. And thanks for reminding me the sub is only 300 rms.
I'll try running each coil to there own channel on the amp.
Thanks again.

If you do that make sure you mono the input signal.

Why keep the signal in mono?

Like i said earlier, stereo on the 2 coils of the same sub is not a good thing. If any signal is out of phase on the 2 different coils, they'll be fighting each other. Guess where the power goes if it's not being converted into sound?
