I have two of these subs in a dual sealed enclosure with a Alpine V-Power MRP-M1000 wired as a 4 ohm mono load and these things pound hard!! I have already cracked my windshield trying to show off with the windows rolled up! These things move so much air it make the coins in my cup holders look like they are levitating! Dont waste your money on any another other sub. For this price these perform way beyond expectation! My car has a very heavy reinforced trunk and it still flexes.

PROS: EVERYTHING ABOUT THIS SUB, PRODUCT PRICES, AND SONICELECTRONIX IS THE BEST HAND DOWNS!!

CONS: IF YOU DON'T WATCH THE VOLUME YOU WILL HAVE PLENTY OF DISTURNING THE PEACE TICKETS!!
