amp and sub compatiability

[d4vew557 10+ year member]

ok. this is my problem.

i have a mrv t420 which is i have bridged i was planning on using it to run a 10" alpine type r but i'm not sure it will be powerful enough. i had planned on purchasing a dual 2ohm voice coil unit and wiring it so the amp see's a 4ohm load.

I think i may need to upgrade the amp in the future to a mono block but if i do i would be looking to run it at 2ohms but the the sub i was going to get won't be any good then as i would need a dual 4ohm unit.

is it possible to run only one voice coil that way i could get a 4ohm sub and use one coil for now then when i upgrade the amp i could rewire it for a 2ohm load.

why not just get a D2, run it at 4ohm now and then run it at 1ohm later on the monoblock... that would make the most sense.... plus power is cheaper @1ohm than it is at 2ohm anyways...

will all mono blocks run at 1ohm
