What is Reddit's opinion of Bbox E12SVPro-Series 12” Single Vented Subwoofer Enclosure?

From 3.5 billion Reddit comments

I’ve had two of those ix-12s in a 3 cuft ported box tuned to 40 hz and they SLAMMED only powered with 650w rms. You’re amp is a scam, you would be lucky to get 400w rms from that thing, your enclosure is in a sealed box, buy a ported one of Amazon or build your own, sealed will not sound good with such little power. These subs are great and I have had only good luck with skar but the lanzar amp and your enclosure are holding it back. Use a box like this: Bbox E12SVPro-Series 12” Single Vented Subwoofer Enclosure https://www.amazon.com/dp/B0013N0UEE/ref=cm_sw_r_cp_api_glt_fabc_GQPM1SEXKHNNGGRCQ4B5 Good luck my guy don’t listen to the comments hating on skar they don’t understand that it is great for people who want cheap systems that beat hard

https://www.amazon.com/gp/product/B0013N0UEE/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1 this is the box I have. I know it's not best to use prefabs but I don't have the means to build a box currently and anything bigger will not work in my situation in my car right now

anything else I could do to improve?

It's a prefab. This one. https://www.amazon.com/E12SV-12-Inch-Single-Subwoofer-Enclosure/dp/B0013N0UEE/ref=sr_1_1?s=car&ie=UTF8&qid=1486184286&sr=1-1&keywords=Atrend+bbox+12. Would you suggest I find someone local to build me a custom box rather than a new amp? I primarily listen to rap. Thank you.

Took me 30 seconds to find that. If you didn't read what I said, I was talking about giving up on 2 subs, and going for 1 good sub. Read next time.

Remember that is a 4-ohm DVC speaker and you can only wire it down to 2-ohms not 1-ohm.

Also if you don't wanna build your own box I'd recommend that you spend a few more bucks and get something with more air space and better quality.

To be honest, that is a horrific setup, avoid at all costs. That amp can and will never do "800w", try 200w max. Also, never pay attention to max ratings, those can be whatever the manufacturer wants, look for an RMS rating. If you think the terminators are bad, those are about 10x worse.

Go with O_HAI_2_U's suggestion, it will be infinitely better with one smaller quality setup, rather than two underperforming 12's. Here's a prefab box that would fit the type-r: http://www.amazon.com/Atrend-12-Inch-Single-Subwoofer-Enclosure/dp/B0013N0UEE/ref=pd_bxgy_e_img_c

$36 BBox E12SV Single 12" Vented Carpeted Subwoofer Enclosure https://www.amazon.com/dp/B0013N0UEE/ref=cm_sw_r_cp_apa_i_4QgfBbRQP2XXC $96 amp and amp kit Rockville RXD-M0 1200 Watt/600w RMS Mono Class D 1 Ohm Car Amplifier + Amp Kit https://www.amazon.com/dp/B01GV6JII6/ref=cm_sw_r_cp_apa_i_GXgfBbV1G2JXE $79 Alpine type S $8 pac SNI-35

Youre looking at $230 with a low output converter.

Would this be a good enclosure

I can't seem to find the 1.5 cubic feet box. Would this one work?

Also, which would be better: Alpine SWS-12D2 or Alpine SWS-12D4

And what size of amp should I get?

Alright, I will buy Rockford Fosgate Punch P2. As far as the box goes how does this look? I am not sure how to find the right type for that sub.

So basically my setup will be that box,

Amp: http://www.rockfordfosgate.com/products/details/p3001

Sub : http://www.amazon.com/Rockford-Fosgate-P2D4-12-12-Inch-Subwoofer/dp/B004UFHXIS

Speakers: http://www.crutchfield.com/p_1131665S/Kenwood-KFC-1665S.html?tp=105

Stereo: http://www.amazon.com/Sony-DSXA40UI-Digital-Stereo-Receiver/dp/B00FB45SRU

Any advice to make it better, or if something is wrong is really appreciated. Thanks again for the help!

with this box and this amp edit: it would actually be about 50-60 bucks cheaper to go this route and you willl have better quality sound
