I Am Installing These Orion HCCA's In My 2000 S10 Blazer. I Had My Kicker Comp V/R's In It. They Would Knock You Out Of My Truck. Any How I'm Facing My Orion HCCA's Forward I Did Some Investigating And Have Come To The Conclusion Why Orion Says Mount Them Up Or Down. Its Not Because Of The Speaker Or Cooling Problems. But Just The Force The Speaker Produces. Facing It Forward You Had Better Have A Billet Proof Box The Front Of The Box Has To Be At Least 1" Thick. Or The Sub Will Break Your Box To Shreds.

The sub is amazing one of the best subs out right now. I'm happy with it.

I would recommend this subwoofer to anyone wanting serious bass. I picked up this at a local audio shop new for the same price as sonic. They had one hooked up in a 3.5 cu ft box at 35 HZ, made the whole building rattle. I have had many large setups but this subwoofer really is by far the biggest and heaviest woofer I have ever owned. Cant even push the cone in because its so stiff with a huge surround and giant spider. Better have some one help you set this beast into your at least 2" thick baffle!

This sub is big. Very heavy and it is built for it. It has huge bounce and creates a ton of noise. The bass is clean on lows, but cuts out most tones you'd expect 10's or some 12's to hit. I have it in a ported box and am only pushing 2,000 watts max to it. I'd love to see what 4,000 could do, but its plenty loud enough til I can upgrade my amp.

I would recommend this sub to anyone looking for loud loud bass. If your even reading this you must be a bass head or competition nerd. I've played with this stuff for 14 years, this subs is one of the loudest single subs I have heard and get many eyes opened concerning that my setup is only 1 15" sub.

Good speaker, very loud. If it was little cheaper that would be awesome. I currently have 4 of these.

i have one of these with 2500 rms soon to be just over 4000 and it handels what ever u can put in to it but altanator and batterys are a must to keep up with it being so hungry

U need batteries at least 4 2400 kinetik with a 4000drf i got 4 15 hcca in tahoe with 2 15000 soundstream xxx amp an 12 xs power batteries the d3100.

So first off you got your 250amp alt your two kinetic 2400 power cells and big three you better if you want to feed these beasts what they want this sub is no toy I have two t-2500bdcp rf amps on two 15.4 hcca subs with all I said above and these do work no joke but put at least 3000rms to each they are way way underrated one t-2500 don't come close to feeding these hogs trust me!!!! And make sure your box is big real big;)

Had it for a few months then checked out the Fi BTL. And hands down the BTL slams harder and displaces more air and better SQ. Not a bad sub at all though.

I have 2 of these monsters running off of a Rockford T40001bd and they pound! You will need at least 1 kinetik hc2400 and 0 gauge wire to your amps! Forget all these other companies Orion makes the best of the best! I metered on a audio control at 153.2 dbs at 34 hertz. So that should tell you something then ran on a term lab at a 150.8 at 34 hertz. I only have 4000 rms. They really slam so buy them.

Awesome sub. Traded my two alpine type x for it and didn't look back, this sub bangs. Hits every note beautiful, especially the lows. This is one bad sub!

just got mine in yesterday made a 5.6 cubic ft box tuned to 32Hertz running off of a Kicker 1500.1 and man this thing is crazy! Makes everything vibrate real bad. sounds real nice n clear n picks up low bass notes like no other. I recommend this product to anyone that is a Bassoholic like myself all my friends envy my sub. This thing is real heavy though. Have someone help u when loading it into your car with the box.

I've had one of these bad boys for roughly 6 months and never have i had any problems. I've ran 1500 rms to it a 2 ohms and it could handle a lot more than that. Just the size of this woofer is massive. I would recommend this sub to anyone looking to turn some heads.

when i first learn about the HCCA Orion subwoofers it was on (YouTube) days and days on (YouTube) looking for a good subwoofer i was still saying to my self who is orion when i was still in love with the mtx 9500's the orion look so small on (YouTube) until i got my 2 Hcca orion 15's on 6-22-09 it came on a brown box and i was thinking its a light box so i can lift it up to my car well its 6-24-09 and my back hurts bad i was thinking wow did they put 2 subwoofer in one box meaning i got to free pair when i open the box i saw just one subwoofer in the brown box i open the orion box and OH MY GOD it dont even look like a 15 inch subwoofer im doing car audio for 6 years now and when i pulled out the orion subwoofer out the box it was the baddest subwoofer i ever see in life i have a chevy blazer and trust me one sub bigger then the car lol i had already build a 7cuft box tune to 35hz and i just test it and OH MY GOD its sound so so beautiful im from the virgin island and we mostly play reggae and the orion sound so beautiful (SQ) and (SPL) i recomend this sub 1 recone kit is the best thing orion has done thank you Sonic Electronix

Awesome subs very loud! Put at least 4000 watts rms to each sub.

I would recommend this woofer it's nice but dc and fi and aa still have it beat by far.
