Excellent sub. Well built and can handle the rms. Currently in a ported, custom box. Sounds great. Very satisfied with my purchase.
Have two d4 10s in my crew cab on a “1000 watt” rms amp at 1 ohm and as loud as they are I can’t wait to hear them on the rp2k
Very nice subs I stared off with two in a 6th order @2ohm sk4500 now I got 4 in a ported box @1ohm sk4500 they take a beating and get loud can’t wait to meter maybe strap another 4500 🙂
