you'll probably lose output if you give them the same power

yea you would need atleast 2500 rms... probably more like 3000-4000 if you seriously want to push 4 L7's nicely

oo yea i plan on purchasing another amp..probabaly a MA Audio Hk4000 i just want to no if spending all that money is going to get me much louder than i already am

well considering you would doubling the power and stepping up woofer's yea i assume it would be louder, what kind of box do you have?

also if your gettin rid of all your old equip memphis amps fetch a good price and 4 l5's could more than pay for 2 L7's

im not sure what size tha box is because i didnt build it i had a professional do it..im guessing its about 7 cubic ft.(ported) ..but i will probably have a little bigger box built for tha L7s

it's impossible to say what your gains will be, since you're basically changing your entire setup, but you should be pleased
