well i came up with this
http://web2.murraystate.edu/andy.bat...ply.htm#levels
and i used a 420w raidmax supply that i half melted the wires on.....cut those all off and am using the other 12v+
It works.....im powering a rockford 500w amp to push my Tempest X.....its working better than the old sansui 80w per channel.....or 160w with both voice coils
I wired the sub in parallel and bridged the amp
thing is when connected to the amp its only at 10.90 volts and drops to 9.9v under heavy load.....still louder and sounds better than the sansui though
What other cheap 12v power supplies are there?? Im really looking to get 14.4V to get the max out of the amp..
