Memphis Audio 16-SRX500D.1

Crutchfield customer from St Paul, MN on 6/24/2017

Amazing amp, worth every penny. Never cut corners when building a new system in your car. I have two 12" JL's pushing 400 amps a piece (nothing crazy), and this amp handles every bit of it and then some. To give a better example, I have it wired into my factory head unit with the bass turned all the way down, still the loudest/clearest/deepest bass I've heard in a while. All around great, reliable and high quality product. Like the other reviews say, you might want a pack of dynamat to go with it because it'll rattle your trunk otherwise. I also use rubber washers under my liscence plate (helps a lot with the rattling)

Pros: Sturdy, strong and reliable amp. Having the addition bass adjustment is a nice perk too! For how small the amp is in size, it packs a hell of a lot of power.

Cons: None.

Extreme Power From Memphis

The Memphis Audio 16-SRX500D.1 Street Reference Amp.... Provides great power for your money! I personally think that the 300Rms rating @ 4 ohms is extremely under rated! It can also be wired to accept a 500Rms @ 2ohm load... I haven't done this as my 2 10' Polk Audio mm series subs that I bought to go with this amp are 4ohm single voice coil, but I can only assume that the 2 ohm Rms load rating is under rated as well!! The volume control knob provided with the amp is great as well, once you figure out how to utilize it properly. This Amp puts out consistant power! Overall, I am very happy and somewhat impressed with this amplifier! If you are using this amp in a single cab truck be prepared to have to also purchase some Dynomat or other sound deadening material...the power provided will rattle every nut and bolt on the cab of the truck!!

Pros: Under rated Rms power!! Small unit, it will fit into a fairly tight space easily! Fits mounted behind the seat with my dual 10" enclosure with room to spare, in a 1976 Standard Cab Chevy Truck!

Cons: This amp will take some time to get your LPF setting and gain control set to your personal preference very sensitive responsive settings! It also takes some time and tweaking to get the volume control knob (bass button) adjusted correctly.

Product Research

Features

Overview: The Memphis Car Audio SRX500D.1 is a Street Reference series mono amplifier for driving subwoofers. Because of its Class D design, the chassis is 53% smaller than its predecessor. The amp features a compact aluminum chassis with textured heatsinks, LED accent lighting, and a remote gain control. The SRX500D.1 comes with a speaker input harness, spare fuses, and mounting hardware.

Output Power: The SRX500D.1 has the following power output:

  • 350 watts RMS x 1 at 4Ω
  • 500 watts RMS x 1 at 2Ω

Controls: The amplifier features the following controls on the end panel:

  • Gain: The rotary Gain control helps you match the amplifier to the output of the source unit. This adjusts the amount of signal required to drive the amplifier to full output. The amp will accept low level signals between 100mV and 6.0V. The amplifier also has speaker level inputs.
  • Low Pass: The variable low pass filter sets the upper frequency limit of the amplifier's output. You can set the crossover point between 30Hz and 250Hz. The low pass filter has a slope of 12dB per octave.
  • Subsonic Filter: The variable Subsonic Filter sets the lower frequency limit of the sub channel's output. The crossover point can be set between 15Hz and 50Hz using the rotary control. The Subsonic Filter helps the amp run more efficiently by cutting out super low frequencies that cannot be cleanly reproduced.
  • Bass Boost: The Bass Boost increases the bass response of the sub channel up to 12dB at 45Hz. You can set the amount of bass boost to 0dB, 6dB, or 12dB using the 3-way switch.

Remote Level Control: Included with the amplifier is a Remote Gain control module. The module mounts under your dashboard or on the center console, and allows you to raise and lower the subwoofer output relative to the rest of the system. The Remote Level control comes with an 16.25' cable and mounting screws.

Protection Circuitry: The amplifier features built-in circuitry to protect the amplifier against overload, short circuit, overheating, and reverse polarity. A Protect LED on the side of the amplifier will glow red when the amplifier shuts down due to any of the above causes.

Connections: The SRX500D.1 has the following connections:

  • Low Input: The amp features a pair of RCA jacks for connecting the amp to the source unit's preamp outputs via an RCA patch cable.
  • High Input: If your source unit lacks preamp outputs, you can connect it to the amp using the high level (speaker level) input. You'll need to splice the unit's speaker wires to the supplied harness and plug it into the amp's 5-pin Molex connector.
  • Fuses: Two 25A ATO (blade) fuses are installed in the amplifier, giving the amplifier a 50A fuse rating. Two spare fuses are included, as well. You should also install a 50A fuse on the power wire within 18" of the battery.
  • Power/Ground: The amplifier features nickel-plated screw-down terminals for connecting the power and ground wires. The nickel plating resists corrosion and maximizes power transfer. The power and ground terminals are 1/2" wide, and will accept bare wire or spade connectors. Due to the 50A fuse rating of the amp, a 4-gauge amplifier wiring kit is recommended. A screw terminal for the remote turn-on lead is also provided. The terminals can be tightened/loosened with a slotted or Phillips-head screwdriver (not provided).
  • Speaker Output: Nickel-plated crew terminals are also provided for connecting the speaker output wires to the amp. The terminals are 5/16" wide, and will accept bare wire or spade connectors. Two sets of speaker terminals are provided, allowing you to connect two subwoofers to the amplifier. The terminals are internally wired in parallel.
  • Remote: The Remote Gain Control cable connects to the amp's RJ25 modular "phone" jack. The remote controls the level of the input signal into the amp.

Q
Can this amp be used for door speakers?

A
No. It's a mono (single channel) amp and made specifically for powering subwoofers. It's built-in low pass filter can be set anywhere between 30 & 250Hz.
