SoundQubed HDS2.1 Dual Voice Coil 600W RMS Series Subwoofers (8-inch Dual 4 Ohm)

This subwoofer is so good I ordered another one. The rated power for this is 600w rms but I run it with a Hifonics Brutus 1116.1 amp and 4g clean electrical and it does awesome even with a ported enclosure that's too small and tuned at 40 hz. I'm excited for the second one to finish breaking in and my baffled enclosure gets done so I can see how the both of them will do!

Thought i was getting the d4s but they dont make that anymore. The 600watts hits good

 This sub is really good for the price Im running a skar 800.1 amp on it and it hits hard clean sound

Hit really hard. I have 2 in my small car and everyone likes the back massage

These subs are sounding better every day
