Priced Individually

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.

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.

	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.

• Auxiliary Battery:
• An Auxiliary Battery is designed for the enthusiast that needs a proper power reserve, that cannot be had with a capacitor. You don't need a HUGE battery! We are well aware that the Hifonics BRX2400.1D is capable of up to 3000 watts of Dynamic Power, but unless you are competing Every day of your amplifier's life then you likely are only using ~half that power at any given time.
• Big 3 Upgrade Kits:
• 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. This decrease in resistance will reduce light dimming, reduce voltage drops, stabilize voltage and current flow, and decrease the strain being put on your vehicle's electrical charging system.
