[QUOTE="tinmanchris217, post: 7097595, member: 610505"] MRV-F409 Power Ratings at 14.4V Per channel into 4 ohms ........................... 60W, 0.08% THD Per channel into 2 ohms ............................ 80W, 0.3% THD Bridged into 4 ohms ................................ 160W, 0.3% THD It's designed to power your side speakers, but could work for subs, depending on their impedance (ohm rating). If you have Dual 4 ohm woofers, you can send each woofer 120 watts, and if they are Dual 2 ohm, you'll send 160 watts to each. Either way will produce enough sound to fill out the sub bass frequencies, but definitely underpowers the woofers. Type R's can handle 600-800, depending on how much you abuse them. Tell us the woofer impedance, and we'll find you a better amp for cheap... so you can let the alpine do what it's meant to do... detailed mids and highs. [/QUOTE]
