just my 2 cents....I have 2 RE8's on a Memphis PRD500.1
it is overpowering them a bit, so I've had to keep the gain and subsonic filter turned down, but...
as long as I dont turn the radio up over 3/4 volume..they do great, sound reall good, even with the lows
On the bad side, they do bottom out relatively easily...so you have to watch what you do...however, a 300 watt amp should work fine with them, if thats what you go with
EDIT>Just a note, I say 3/4 volume, but that really depends on the song....some songs I can play at full volume and I meant they try to bottom out at higher volume, not that they sound any worse.
