After 30 years of window shopping and wait are over. Will recieve my shinny new RF-83's & RC-64 tomorrow. I have a question on what is the proper amopunt of Amp required. I have an old crown power base 2 rated at 325 Amp - 8 ohms per channel. From Crown I got the following recommendation: Using the specs for the RF-83 of 250 watts Continuous/ 8 ohms you would be looking for an amplifier that could do about 500 watts into 8-ohms that is rated between 400 watts and 625 watts. 250 x 2 = 500 watts for 3db of headroom. 500 watts x .8 = 400 watts 500 watts x 1.25= 625 watts So, I have speakers rated 250W rms, can I really connect a 325Amp with out burning anything up? Regards..
