SoundQubed HDS2.1 Dual Voice Coil 600W RMS Series Subwoofers (12-inch Dual 2 Ohm)

Ordered 2 wired down to 1 ohm very pleased with the power they put out

I bought the 10" HDs and the 900 watt amp but the truth is that the 900 just isn't enough power. So I bought the 1200 watt sq amp and it slams!!!! Don't forget to break your sub in first and once it's broken in you will see how awesome these subs really are.

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

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!

After tuning, it hits as low as 5hrtz! Resonates high and very low bass tones no problem plus moves a lot of air. Shipping was fast.

When i opened the box i saw damage on the magnet to the speakers and when i hooked them up they sounded sloopy i got bad product

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

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