As of right now, i'm looking for a pair of HIGH SPL subs for my vehicle. Space is not an issue... I will be powering them with a Powerbass XA3000D, So if they are dual 4 ohm they should handle around 1500 watts RMS... If dual 2, around 1000 RMS. Also, if you have ONE high SPL sub, I can buy it from you and purchase the other elsewhere. Money is not an issue.
