[QUOTE="Ron Kimball, post: 105165, member: 405"] Re: Ipr2 5000/7500? They definitely don't suck but you do have to understand what the ratings mean. If you're one of those guys that believes you can get 7.5KW continuous out of a 2400W circuit (120V x 20A) you ought to fix that ;). IMO the IPRs (and most other amps) shouldn't be pushing below 4 ohm loads with EDM. You also shouldn't be exceeding the RMS rating of your subs unless you have sophisticated adjustable limiting such as the iTech has - and even then with EDM it doesn't gain you much. My "big subs" are 18" folded horns with 800w 4 ohm drivers that match up to my IPR3000 nicely (840w/ch # 4 ohms). I can push that into the red without worrying much. Of course they don't go very low so I have them properly high passed and "cheat" with a MaxxBass hardware unit to get down to 25 Hz ;). [/QUOTE]
