Alpine R2-DB8V-TRK Halo Series 8″ Ported Dual Subwoofer Enclosure with two 8″ R2-Series Subwoofers

Your truck deserves more than any old subwoofer system — you want sound and style. Alpine’s R2-DB8V-TRK loaded subwoofer enclosure gives you both. This versatile enclosure features two of Alpine’s new R2 subs and will fit most full-size trucks.

Solid subs

The R2-DB8V-TRK features two Alpine R2-Series subwoofers with Kevlar-reinforced pulp cones and rubber High Amplitude Multi-Roll (HAMR) surrounds for dependable performance at high volume levels. The enclosure handles up to 750 watts RMS so you’ll get the solid bass you’re looking for and is wired for a 2-ohm load, making amplifier selection simple. The enclosure’s side-firing ports use your truck’s interior to boost the lows, giving you deeper bass at higher volume levels.

Easy to fit

The rugged 5/8″ MDF enclosure is clothed in black carpet covering that combines toughness and good looks, with a central metal Pro-Link™ bracket that lets you adjust the enclosure’s total width from 40″ to 51″ to fit most full-sized trucks, plus Jeep Gladiators and 4-door Wranglers. An integrated amplifier mounting tray optimized for Alpine’s mono sub amps gives you a package designed to fit under the rear seat of your truck, and its EZ Change twist-lock grille system gives you speaker protection options to coordinate with your truck’s interior. Adjustable mounting feet ensure a secure fit.

JL Audio JD500/1 Monoblock Class D Subwoofer Amplifier – #98362

JD500/1 Monoblock Class D Subwoofer Amplifier, 500 W x 1 @ 2 Ohm / 250 W x 1 @ 4 Ohm – 14.4V

Designed to produce a whopping 500 watts into 2 ohms (14.4V, 1% THD), the JD500/1 amplifier is a great solution for powering subwoofers in a cost-conscious system. Our proprietary NexD™ switching technology delivers large amounts of real-world power output with excellent efficiency and ultra-low distortion.

The JD500/1’s controls are located on the input panel. while the power and speaker connections can be found along the opposite end of its extruded aluminum chassis. Signal processing features include a 12 dB / octave low-pass filter, with continuously variable frequency selection from 50-500 Hz, and a variable bass boost EQ. Dual-range, differential-balanced inputs are also on-hand, capable of accepting line-level and speaker-level signals. Automatic turn-on capability (via signal sensing or DC-offset sensing) is standard, along with a set of preamp outputs so you can easily pass signals to another amplifier.

The JD500/1 is also equipped with an onboard LED-clipping indicator ring, surrounding the input sensitivity control. This useful feature lets you set your amplifier’s input sensitivity, quickly and accurately, without special equipment. With the addition of an RBC-1 remote level control (sold separately), you can control the subwoofer level from the driver’s seat.

Power up the bass

JL Audio’s JX Series amplifiers were very popular with our customers, garnishing rave reviews citing their tremendous performance and value. We think their latest JD Series amps will follow in their footsteps, offering superior power and serious features for your dollar. The JD500/1 mono subwoofer amplifier will send up to 500 watts RMS to a sub, so you’ll hear and feel the bass the way you want it. A variable low-pass filter and bass boost help you tune your sub to fit your system and sound its best. An optional wired remote control lets you turn the sub up or down from the front seat.

Connection features

The amp includes speaker-level inputs with signal-sensing amp turn-on, along with preamp inputs and outputs, so it’s ready to work in virtually any system. Differential-balanced inputs plus JL Audio’s NexD™ amp technology keep the signal sounding pure and noise-free at all times.

JD500/1 NexD™ Switching Technology

Summary:
NexD™ amplifier technologies produce exceptional audio quality, unsurpassed total efficiency and high power from very compact amplifier designs.

Detailed Information:
Beginning with the original ‘Slash’ subwoofer amplifiers, JL Audio has been at the forefront of Class D amplifier design. Our NexD™ switching technology stems from our Class D expertise to deliver outstanding fidelity and efficiency, leading to compact amplifiers that deliver high power and exceptional value.

Let’s get a little nerdy… A traditional PWM switching amp design uses a fixed switching frequency and varies the pulse width based solely on the audio input signal to the pulse modulator. This basic approach assumes some ideal conditions, like a rock-steady power supply, that do not necessarily occur in a real, in-car installation. Power supply sag with signal causes distortion at all power levels with these designs, even well below clipping. The cure for this is feedback (a corrective signal sent back to the input side), but this becomes impractical as the audio frequency increases, making it a good solution for band-limited (subwoofer) amps, but not for full-range amplifiers.

Taking the above into account when designing the NexD™ subwoofer amplifiers, we have taken the simple fixed PWM approach and enhanced it with a very high switching frequency: 240 kHz, which is about 4x higher than most Class D subwoofer amplifiers. This pushes the amplifier’s bandwidth to at least 500 Hz with minimal distortion and improves efficiency, while keeping typically bulky circuity more compact. Your subwoofers will reward you with tight, rock-solid bass performance.

For the full-range NexD™ amplifiers and channels we applied a variable, ultra-high speed version of the NexD™ technology (switching at well over 400 kHz). In these designs, a self-oscillating modulator with “feed-forward” sends information about the instantaneous power supply voltage to the modulator, combining this with the input signal to cancel out any distortion due to supply voltage fluctuation. This reduces distortion prior to applying feedback, simplifying the overall feedback loop design.

The bottom line is simply great audio: clean, powerful and reliable.

JD500/1 Differential-Balanced Inputs

Summary:
JL Audio’s Differential-Balanced Inputs are engineered to combat induced cable noise, which is a common problem in car and marine audio installations. This technology allows for the use of conventional RCA cables, while delivering many of the benefits of a true balanced connection and accepting a wide range of input signal levels.
