Is it true that... You get +3 db for every sub you add then +3db again if you supply that sub with the same power? So if I have one sub at 1000 watts hitting 140 db, I add another sub and supply it with 1000 watts as well I should be around 146 db?
Reason is I am currently running one sub at 2 ohms to 900 watts but once I get my second 12 their going to be at 1 ohm, but only 600 watts a peace (until I can afford new amps). So I am adding 3 db by adding another sub but the power is lower to both. Any difference in sound at all?
