Quantity: 1

Belva Subwoofer Boxes with Polyfill and 3/4-inch MDF

Built for Bass

You've got an awesome subwoofer there, pal. But where's it gonna go? You can't just throw that thing in the trunk and call it a day. Don't worry, Belva's got your back. With superior construction, great features and everything you need for bass, you'll be ready to pass up that entry-level box you've been eyeballing.

Belva Subwoofer Boxes are CARB Phase 2 Compliant

You get quality boxes with solid 3/4" MDF because nothing else will do the job right. You want to flex your windshield, not your box's innards. You get polyfill built into the box, making sure your subs perform perfectly. On top of that, you get a box that's CARB Phase 2 Compliant, meaning your box won't emit as much nasty formaldehyde as the competition. Better for your bass and better for you.

Belva MDF 3/4-inch Thickness

Look, nobody buys a subwoofer and says, 'Aw man, I just want a teeny bit of thump.' Naw man, you want something that kicks you in the chest, but you need a box that's gonna put up with it. That's where Belva comes in. While other brands use less-than-optimal 1/2-inch MDF, we've got 3/4-inch MDF to make sure you get all the bass you can handle. Why risk a busted box? Belva's the obvious choice when it comes to giving your sub a good home and giving you the low end you're looking for.

    • To get the most out of your new power system check out our Big Three Upgrade Kits. Performing the "Big 3" upgrade to your vehicle will improve the performance of your electrical system and increase its current handling capabilities.

The following review is for BAK02, which is a part of the bundle you are viewing.

This wire is very flexible and fit nicely in my 2000 nissan maxima. ring terminals were a little fussy, but that was operator error. very nice 150 amp fuse. Lots of wire crammed into it. Very inexpensive for the quality. I would recommend this to anyone looking for an upgrade.

Decent Amp Kit

The following review is for BAK02, which is a part of the bundle you are viewing.

I am a professional installer first of and my father is an electrician. Following the AWG- American Wire Gauge standards this is not 1/0 wire it's closer to 2AWG, please understand that true 1/0AWG copper wire will cost around $5-8 a foot.

That being said for the price it is an amazing kit but should be marketed as 2AWG.

When compare to Kicker and Memphis true to spec 1/0AWG wire there is a major difference in size and weigh over all. 5 feet of Memphis 1/0 Wire weigh the same as 17 feet of Belva 1/0AWG.

The following review is for BAK02, which is a part of the bundle you are viewing.

I have never ran 0 gauge before and when I got it and took it out I was surprised but the big wire didn't really hurt the install it is still hidden under the carpet and it's thick and flexible so it was easy to run through the firewall. Now I'm gonna get the Belva big 3

solid amp

The following review is for BRX2400.1D, which is a part of the bundle you are viewing.

I have this amp running 2 skar vvx 15v2s d4 wired to 1 ohm. Gain only half way more power than they can handle. I have the big 3 done with 1awg ofc nvx wire and a extra battery xs d 3400. Still have to get an alt. My current alt is a 105 amp. And other battery is a everstart 800cc amp. This amp is power hungry. I also recomend putting the remote wire on a seperate switch. My head unit stopped turing it on . S***ty pioneer. Amp will get hot but it wont turn off. Just give it plenty of breathing room underneath. Great product. I slam it for 45 minutes at a time. My commute to colledge. Everyday . About three months now. Like i said only prob wws the remote wire . That happened about 2weeks after i bought it.

True 0 AWG!

The following review is for BAK02, which is a part of the bundle you are viewing.

This kit comes with everything you need for a 0 AWG amp install with RCA inputs.


I would definitely recommend purchasing this kit if you need a quality 0 AWG kit at a fair price with super fast shipping!
