What customers say about "Size & Weight"
ORION HCCA124 Subwoofer 12" Dvc 4+4 Ω 5000W
  • The size is just right and the wattage excellent. 5000 watts is more than enough.
  • If you're using a sub woofer amp, then no problems. It sounds very good, especially for its small size.
  • The sound quality on this sub is pretty good for it's small size. Great bass, deep and clear.
  • Heavy gigantic speaker that is very power hungry. Do not buy unless you upgrade you're entire electrical system.
  • This woofer is OK its light weight which I really didn't like.
Sundown Audio Z-12 V.5 D2 12" 2000W RMS Dual 2-Ohm Z-V.5 Series Subwoofer
  • Fits perfect in the standard hole on parcel shelf and rattles the rear vision!!
  • It fit perfectly, exactly this same size as stock. Great value and great sound.
  • These are amazing!!! I'm thinking about getting 2 more. The sound quality on this sub is pretty good for it's small size.
  • Sound is pretty good, bass is decent for such a small speaker with no amp, you can see it flex & it's cool that the speaker is covered.
  • Barely fit into my small trunk enclosure. Had to make modifications, but so far it's much better than I expected.

What customers say about "Audio"
ORION HCCA124 Subwoofer 12" Dvc 4+4 Ω 5000W
  • I have 1 of these and it pounds. I had a box built to specs and trust me get ready... Great sub and great sound with deep bass I plan on getting 1 more real soon.
  • I have owned many different subs and audio systems and these subs can be compared to the best. Amazing and clear sound.
  • These subwoofers (with adequate power and a good enclosure) are amazing and will blow you away. You get a lot of bang for your buck with these.
  • Love this sub. I've owned a lot of subwoofers in my day this is by far the best one I've ever had. It's sound is unmatched.
  • This speaker will make your hair stand up solid hits .louder and cleaner then the w7.
Sundown Audio Z-12 V.5 D2 12" 2000W RMS Dual 2-Ohm Z-V.5 Series Subwoofer
  • This hits the hardest at lowest frequencies, so rock and country fans let this be known.
  • I've had subwoofers in my car since 2009 and these are the best sounding 12 inch subwoofers I've ever owned. Very deep bass with rich mids.
  • Amazingly powerful and deep bass coming out of a subwoofer, better than what i expected, especially at this price.
  • The sound is very clean, and these vastly outperform the older speakers.
  • Beware...if you want high volume bass or listen to your stereo cranked, don’t expect much with these, they don’t handle very high volume very well.

What customers say about "Features"
ORION HCCA124 Subwoofer 12" Dvc 4+4 Ω 5000W
  • I really like the cone, because it is a treated heavy paper. It has a nice tone and decent excursion.
  • These speakers appear to be very well built, have a solid magnet, and I really like how they've sewn the cone which gives it a high end driver look.
  • The build quality is stable with and rigid cone and the mounting screws are strong enough to withstand even upside down placement.
  • Played this sub for 3 days and it blew. I know its a very outstanding sub but some reason it gets very hot. Was breaking it in still at 2 ohm. Got hot and just quit.
  • If you have the dough I highly recommend one or two. The only downside is how power-hungry they are.
Sundown Audio Z-12 V.5 D2 12" 2000W RMS Dual 2-Ohm Z-V.5 Series Subwoofer
  • I am totally impressed with the quality, and versatility of this unit, the cost was reasonable, and the quality is great.
  • For the price, this speaker is amazing. Sturdy construction and simple design.
  • This sub will directly replace a 2002 BMW Z3 Harmon Kardon 6.5" sub woofer using a 1/4" flat spacer ring. Sounds as good or better than the original.
  • I will warn you that it can not handle low substained tones because it over heats the voice coils which will fry it
  • Aftwr a few months the foam ring disinegtatedand speakers blew out, but they did sounded nice when they worked.
