havn't had it DB measured, wouldnt mind though, just to know. its enough for me! without spending serious amounts on a big yella battery + alternator upgrade + 0awg wire it cant go any louder really. the amps are bit too small for the sub really but its not too bad!
( top pic: rockford fosgate american import 2ch 360w RMS bridged running right hand sub = vibe 12" black air 1400w or 1200w max?
bottom pic : alpine amp 300w max running vibe componants in front doors + american pro import 2ch about 600w RMS bridged running left hand sub = pioneer 12" 1400 max w + 2 power caps which are relativly useless
I know both sub amps could be a bit bigger but I have just upgraded the subs ( again! ) and I am working on it! The sub amps are very underrated amps and as they are american import, and the subs are not they are quite happy to push the subs all day long without much heat or sound quality issues, one for the future though, im thinking US amps, they do some nice stuff!
