About the Rockford Fosgate 250-Watt Bass Package
All your bass in one place
All your bass in one place
Which sub do I buy? Which amp do I get? Putting a bass system together for your vehicle can be confusing, so we've eliminated the guesswork. This Crutchfield-approved bass package features Rockford Fosgate's R250X1 amplifier and their R2D4-10 subwoofer, along with Sound Ordnance's BB10-125V ported enclosure, a great combination that will get you and your car rockin'. Just add wiring and you've got a recipe for deep, satisfying bass.
Rockford Fosgate performance in a small package
The Prime Series R250X1 mono amp sends 250 watts RMS to the sub, so you can really feel your bass rockin'. You can use the low-pass filter and Rockford Fosgate's famous Punch boost to get the best possible bass from the sub and enclosure in your vehicle. A phase switch gets your subs firing along with your other speakers for maximum impact, while the speaker-level inputs let you hook this amp up to almost any system, even a factory stereo.
Rockford Fosgate's Prime R2D4-10 10" sub features a mica-injected polypropylene cone that works with a high-density poly-foam surround to handle up to 250 watts RMS. Rockford Fosgate stitches the tinsel leads that carry the signal to the voice coils directly into the cone — they'll hang tough through heavy use so you get consistent, reliable performance. The stamped solid-steel frame offers venting usually found in high-end subs that keeps this sub running cool. Dual 4-ohm voice coils allow you to wire this sub for 2-ohm impedance to get the most out of the Prime amp.
Sound Ordnance's BB10-125V ported enclosure holds one 10" subwoofer and offers an internal volume of 1.47 cubic feet. This rugged Bass Bunker enclosure comes built to last and ready to help your sub deliver real low-frequency firepower. This high-grade, medium-density fiberboard enclosure uses sealed inner braces to help combat resonance by reducing vibrations, while tough black carpeting defends against incoming nicks and scratches. The large vent features rounded inner corners that keep port noise to a minimum for more accurate response.

More details on the Rockford Fosgate 250-Watt Bass Package
CEA 2006 Compliant: The R250X1's power ratings and signal to noise ratio are measured according to the uniform standards advocated by the Consumer Electronics Association (CEA). This allows you to accurately compare these specifications for all CEA-2006 compliant amplifiers, even different brands. Manufacturers who adhere to these standards can display the CEA 2006 logo on their products and packaging. CEA-2006 Specifications for this amplifier are:
- 4 Ohms: 150 watts RMS x 1 at 4 ohms, 14.4 volts, and less than 1% THD+N
- 2 Ohms: 250 watts RMS x 1 at 2 ohms, 14.4 volts, and less than 1% THD+N
- S/N: 80 dB, measured at 1 watt output (100 dB measured at rated power)
LED Indicator: The amplifier is equipped with an LED power/protect indicator. The LED illuminates blue when the unit is turned on. It illuminates red if the thermal or short circuit protection circuit is engaged, and the amplifier will automatically turn off.
Mounting: The amplifier can be mounted vertically or horizontally using the supplied mounting screws. The amplifier should never be mounted in an engine compartment as this will void the warranty.
- Gain Control: Use the amplifier's gain control to match the output of the source unit. The rotary gain control is labeled 1 to 11 and has a sensitivity range of 150mV to 4V when using a preamp level signal, 450mV to 12V when using a speaker level signal.
- Remote Punch Level Control: The R250X1 includes a wired Remote Punch Level Control, linked to the gain control of the amplifier. The module allows you to remotely control the output level of the amplifier from the dash or center console. The Remote Punch Level Control features a rotary dial, and comes with mounting hardware and an 18' cable.
Note: The Remote Punch Level Control measures approximately 1-3/4" wide (2-5/8" including the mounting flange) x 3/4" high x 1-5/8" deep (2-1/8" deep including the knob and wiring).
- Crossover: The amplifier is equipped with a 12dB/octave Butterworth low-pass crossover. The crossover point is continuously variable from 50 to 250 Hz. This being a subwoofer amp, the crossover is always engaged.
- Phase: The 2-position phase switch allows you to easily reverse the output phase of the amplifier, choose 0° or 180° to match the rest of your vehicle's speaker system.
- Punch EQ: The Punch EQ bass boost circuit is adjustable from 0 (min) to +12dB (max) and centered at 45Hz.
- Power Terminals: The power and ground terminals are nickel-plated set screw terminals and will accommodate up to 4 gauge power and ground wires.
Fuse: An external 30-amp fuse (not included) must be installed on the power wire at the battery. If a wiring kit is used which includes a fuse with a value other than 30-amps, the original should be replaced with a 30-amp fuse.
- Remote Turn-On Terminal: The remote turn-on terminal is a nickel-plated set screw terminal that will accommodate up to an 8 AWG wire. It's used to remotely turn the amplifier on and off.
- Speaker Terminals: The one pair of speaker outputs is nickel-plated set screw terminals what will accommodate up to 8 AWG speaker wire.
- RCA Input Jacks: The industry standard RCA jacks provide an easy connection for preamp level input. They are nickel-plated to resist signal degradation caused by corrosion.
- Speaker Level Input: A speaker level input harness is included, making it easier to add the amplifier to a factory radio or to a receiver with no preamp outputs.
- RCA Output Jacks: A pair of RCA pass-thru jacks provides a convenient source for daisy-chaining an additional amplifier without running an extra set of RCA cables from the front of your vehicle to the amplifier location.
- Wired Remote: An RJ-25 jack is used with the included Remote Punch Level Control.
- Width: 11-1/4"
- Height: 2"
- Depth: 7-3/8"
