so i ordered a 15" kicker L5 with the box already around it the sub is 750 watts RMS and 1500 watts peak. right now i have a Phonics Digital PD-2610 2-Channel 1000W Amplifier i was wondering if this would be enough to power that beast. also if i get some tweeters is it necessary to get a four channel amp or do you think Dayton Audio DC28F-8 1-1/8" Silk Dome Tweeter theese will sound ok without? thanks guys and ladys
