Ok would it make sense to bridge my amp if im gonna buy 2 subs im wondering cuz its a 2 channel but once i bridge it becomes a 1 channel so does that mean 1 sub per channel?

you should have made all of these under one post.... if you bridge the amp you are correct you only have one channel now, but that dont mean you can only have one sub.... but if you have the amp bridged you need the combined ohmic load to be at 4 ohms between the speakers.... to achieve this you will need 2 dual 4omh voice coil subs. subs will be wired in series... this means sub A and sub B(pos + voice coils with dots will be wired to the pos + terminal on the amp) then sub A and sub B(neg - voice coil with dot will be wired to pos+ voice coil without dot) and then both sub A and sub B(neg - voice coils with out the dots will be wired to the neg - terminal of the amp...
you will only use one jumper per sub... goes from neg with dot to pos without a dot... if you are still having troubles look at wiring diagram #2
