Is 350 watts RMS enough for a daily-driver sub?

Yes for most listeners. 350 watts RMS in a sealed box gives solid bass in a car; a 500-watt mono amp leaves headroom.

What size enclosure does it need?

It is designed for a sealed box and needs about 5 inches of mounting depth. Check your box's internal volume against Rockville's recommended spec before buying.

Can I wire it to a 4-ohm amp?

It is a single 2-ohm voice coil, so it presents a 2-ohm load. Make sure your amp is stable at 2 ohms.

Does it come with a grille or box?

No. The box lists a mounting gasket only, so you supply the enclosure and any grille separately.

Is $57.95 a good price?

It is the lowest of the four stores listing it new and sits at the bottom of its recent range, so it is a good buy at that price.

Will it fit a Nissan Titan?

It is listed for the 2007-and-later Titan, but check your specific cab and box space against the 5.03-inch depth.

Our take on the Rockville 12" Sub

The Rockville 12" Sub is a single-voice-coil car subwoofer rated at 350 watts RMS (700 watts peak) with 2-ohm impedance and 88 dB sensitivity. It uses a vented T-yoke for heat dissipation and chrome-plated binding posts, and needs a sealed enclosure with about 5 inches of mounting depth. At $57.95 at Rockville Audio as of November 6, 2026, it sits at the low end of its recent range and is cheap for a 12-inch sub.

Pros

350 watts RMS is solid output for the price
2-ohm single voice coil pairs easily with most mono amps
Vented T-yoke helps shed heat during long play
Shallow 5.03-inch mounting depth fits many boxes
88 dB sensitivity means modest amps can drive it

Cons

Single voice coil limits wiring flexibility versus dual-coil subs
Needs a sealed enclosure, so box cost adds up
88 dB sensitivity is only average, so it wants real power
No waterproofing, so it is car-only
Not a true sub-bass monster at this size and price
