what would sound better 1 10w6v2 or 2 10w3v2's?

 

you should ask:

1 10W6 or
1 12W?

I would goto 12W? if space is permitted. Also depends on what kind of music you listen to...more low bass or mid bass?

I had a 12w3 in the hatch that occupied the spare tires, but I decided to replace it with a Alpine 10" Type-R sub in a custom fiberglass box, it actually sounds pretty similar. Now I have sub and spare tire!

It's all about tuning I think....
