the RE amps is way underated sayes 1200 that can push to a close 1600 i heard but ed.9 equivilant to RE is a big no. the RE is in a class of the diamond, treos, and mmats. the ed 9 is towards the jbl,hifonics and mtx.
never seen or heard the RE amp but if its nearly as good as their subs then its really good...as for eD.9 those amps are supposed to be really good too but it might not be as good as the RE but thats just my 2cents
