OK, I bought these subs because I liked the slim profile and they are the only subs I could find to fit the box behind the seat of my 99 Ford F250 Crew cab. I have them perfectly matched to a Boss NX2000.2 amp. They hit OK and thats it. High volume they like to distort. your not going to flex glass with a 1000 watt RMS pair of these subs... Makes me miss my bandpass box in my old pickup BAD! If you are looking for suplimental bass to a mild system these will work well but if you wanna bang make more room and go get you some "2 Pack of Kicker CVR124 (07CVR124, CVR12 Dual 4 ohm)" and a bandpass box.
