I havent installed them yet...but i have tested two of them in a ghetto box and they shook my car pretty good....they nearly matched the ouput of my Kicker L5 in a vented box off the same power, about 400 watts for both....
Once im done with the install they will run off one Ampman Revo 1500 with the gains down.....they should get around 300 each....what kinda power you have?
