1 12"
1 10 and 1 12
2 10s

cant decide what to pick for a sub..

2 10s. Why not 12s?

Do you want alot of loud bass? or just clean all around decent bass?

Depends on the Sub brand.
Depends how much space you have.
Depends how you want it to sound (loud bass vs clean bass vs clean loud bass)

Give more info and what you were thinking to get.

well for my budget i got this(what subwoofer recommended), since i was also buying all speakers, 2 amps, and a sub, plus new battery etc.

Guess i want just clean/loud bass maybe, i dont listen to songs with alot of bass, like double bass shit with metal.

You definitely want a sealed enclosure for listening to metal.

well i dont listen to metal really
