Then if it happened to be a 4Ohm (worst case) rating when the speakers are 8, you're looking at 16W into 8 Ohms.37w rms a side isnt actually that far off when you consider that rating is at 0.3% distortion. (im not counting the subwoofer outputs)![]()
EDIT: As it's 6, and most amps are rated for their power at 8, you're looking more like 25W per channel at 8 Ohms with the similar distortion level adjusted by james.
