wiring 8 inch sub with two 12 inch subs?

ok i have two dual voil coil 12 inch kicker cvx's(700 watts rms)  i have them wired to a 2200 rms two channel power acoustiks amp i have them bridged, wired in paralell equaling a 1 ohm load,   and i just recently got an 8in kicker L7 (450 watts rms)  and i was trying to figure out if i can wire them all up to equal 1 ohm, or would i have to get a second 8in sub to make it even, the amp has more than enough power for it all but i would like to know how i could wire it up safely.

First of all that amp isn't doing anywhere near 2200W. You might get Half that. It's Power Acoustic, famous for inflated BS numbers.

You do not want to mix the 8's and the 12's. Pick one or the other not both. Now if you want to crossover the 8" at a different frequency, seperate enclosures, adding additional amp channels that's something different.

Adding the 8" and the 12's together will offer you no advantages.

ok thank you ill just stick with the 12s

yeah just stick with the 12s.  if you need more midbass then you could run the 8 on a seperate amp with a crossover so it will only reprocdue the midbass frequencys
