Why do you guys not have the hdc3 12 2ohm

The hdc3 series is awesome and the break in peroid is crucial I had a sundown sa15 that says the break them in before had and I used it a low power for like a week and once I turned it up it didn’t last then I put my hdc315 back in and I’m still slamming on it now for 1.5 years and almost full tilt

These subs are absolute monsters!!! I got 2 on a 4500 and they are so amazing I’m ordering more!!! Way better than the price point makes you think!!!

Most of the 1 star reviews are from people that don’t understand the term “user error”. I was skeptical about mine at first. It took roughly 4 months to break in and sounds awesome in my daily. This sub has a STIFF suspension and is generally designed for COMPETITION use, hence the name. If you want a sub to beat the S#!+ out of, go with the S series. They are a lot better for musical applications. Don’t let the people leaving negative reviews turn you away

I bought the HDC312 and the 2200d. Had it running at 2ohms for about a year. Then….. I got eh 4500.1. GEEZUS KRISTS!!!!! I have it in a 2013 Jeep Grand Cherokee. In a 3.5cft box tuned to 32HZ. I’ve had 3 JL W6 12″s, 3 Fosgate HX2’s. A Mojo 15…and this HDC312 and 4500.1 hits so hard. Got the 4 Channel also, best sounding system I’ve ever had in my life. Thanks SoundQubed
