Item Condition - Like New (Open Box):

This product works and looks like new. It may have been opened for a visual demo or product video. In some cases there may be signs of an attempt at installation like opened packaging or mounting screw holes used, but there is no real sign of use or wear. Includes all original parts, packaging and accessories (or suitable replacement)


RD500/1

Born to produce a whopping 500 watts into 2 ohms (14.4V, 1% THD), the RD500/1 amplifier was engineered to generate tons of pure subwoofer bliss from a sleek, ultra-compact chassis. The secret behind its power proficiency is our proprietary NexD switching technology, which delivers large amounts of power output with precise efficiency and ultra-low distortion.

For your convenience, the RD500/1’s controls are located on top of the amplifier, beneath a protective cover, with all connections found along one side of its 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 most input voltage levels. 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 RD500/1 is also equipped with an onboard LED-clipping indicator. This all-new, innovative feature lets you easily set your amplifier’s input sensitivity setting, quickly and accurately, with no special equipment needed. The RD500/1 features a durable, black powder-coated finish and a top-mounted, dual-color LED light strip that reports the overall status and condition.

Small with plenty of power

The following review is for RD500/1, which is a part of the bundle you are viewing.

Great little amp. Quality is great I mean it’s a JL. The amp puts out clean power and I’ve even pushed more than I thought it could handle and it sounded beautiful. I power two 8-inch JL micro subs in a ported box. They hit harder than they are supposed to and paired with this amp, they are a match made in heaven. I bought this one over the JD mode bc of the color and the led light on top which tells you what the amp is doing. Make sure to get the JL bass knob which can be installed and where just drill your hole and it will look OEM. Pay attention to the +/- ports bc they are close together and can confuse you if not paying attention. Now I’m waiting on the RD400/4 to have a matching pair of JL amp. I’m anal like that and I highly recommend these amps that actually put out the stated power and even over. No subsonic filter just bass boost and LPF.

Awesome Amp

The following review is for RD500/1, which is a part of the bundle you are viewing.

I bought this amp to run with my Stealthbox in a c6 Corvette. Amp delivers big power for a small size. I highly recommend for a W3v3-2 or smaller.

What’s not to love?

The following review is for RD500/1, which is a part of the bundle you are viewing.

This little amplifier is absolutely amazing! It is very small and delivers a very solid amount of power. I have this driving a JL 12 W3V3, and it is very capable of driving it to its limit, all while remaining as cool as a cucumber. This thing, regardless of how hard you push it, never seems to even get warm. Add to the incredible performance the capability of setting the gain easily using the included clip indicator light, and you have an absolute joy to deal with. I highly recommend this amplifier. Oh, one last thing; the optional remote knob is an absolute must.
