Great amp

Crutchfield customer from Montgomery, TX on 6/28/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

I give this amp 5 stars for performance but the instructions were far from excellent. This was my first amplifier install so maybe I'm just not up to speed on what would be second nature to others. Other than the instructions, the amp is great. Im using it to drive a kicker 10" sub and the performance is awesome. Great bass and trouble free operation.

Pros: Ease of operation Great performance

Cons: Terrible instructions

Really nice compact amp that im using to power a rockford fosgate marine 10" sub. Fits nicely tucked away in the center console of my boat and performs well.

Pros: Small, powerful, comes with fuse block

Cons: None at this time

Very small size with a lot of power! You just have to make sure you have the crossover set to your liking before you mount it, as the switches are on the bottom.

Great amp for the price and size.

Pros: Size, cost, power

Cons: Freq Setting is located on the underside of unit. So making adjustments once the amp is mounted is not possible.

This is a great amp. Compact, solid performance, doesn't get hot. I have it pushing a 10" DVC sub, and it does not disappoint.

Pros: Size, quality, water and dust resistant.

Cons: None.

Awesome Amp!

Jordan from Somewhere in NC on 8/4/2017

Verified customer (What's this?)
Verified employee purchase (What's this?)

Love this amp! I got it to install in my 2005 Wrangler and the mounting options were endless. It would fit just about anywhere I wanted to install it. Since it is weatherproof I may get an extra one to install in the new boat I am looking at getting. It was easy to install and has a connector that you install the power wires to as well as another connector for the remote wire/speaker wires and another for the RCA inputs (that can be cut for high level input) that can be pulled out so it is easy to remove and reinstall if needed. I almost installed it under my steering column but wanted to keep it close to my capacitor so ended up installing under the rear seat.

Pros: Small and compact with great power Easy to install and remove without unscrewing all the wires due to the connectors

Cons: Inline fuse feels cheap, hard to open

Great amp in a small package

Chris from Columbus, Oh on 9/24/2016

Verified customer (What's this?)
Verified employee purchase (What's this?)

This form factor of amp is wonderful! If you have a tight spot and need an amp to fit with a good amount of power, this is a great option.

Pros: Small package, price

Cons: Not really a con... but I would like to see higher output amps in a similar form factor.

Product Research

Features

Overview: PXA series amplifiers are designed for motorized vehicles with small battery/charging systems; Kicker's new Direct Amp Technology uses the vehicle's charging system as its power supply, offering 90-percent efficiency. Little ventilation is required and with its small footprint, the PXA500.1 can be installed in motorcycle saddle bags or fairings, glove compartments, or other small spaces.

Power Output: The PXA500.1 is a mono amplifier designed to output 250 watts RMS at 4Ω (<1% THD+N) and 500 watts RMS at 2Ω (< 1% THD+N).

Controls: The controls for the amplifier include a rotary gain control and five DIP switches. The DIP switches, located on the bottom of the amp under a rubber cover, can select the following:

  • Low Pass Crossover: 60Hz, 80Hz, 100 Hz, or 120 Hz; low pass crossover cannot be bypassed
  • Bass Boost: On/Off; +6 dB boost centered at 40 Hz
  • Input Level: select high (speaker level) or low (line level)
  • Auto Turn-on: select 12V (amp turns on when +12 volts is applied to the remote wire in the harness) or DC (amp turns on when a 6 volt surge is detected from a speaker level source)

Input Signal: The PXA500.1 is capable of receiving either high- or low-level input signals, and you can select the input type on the bottom of the amp (DIP Switch #4). An input harness with stereo female RCA jacks is included. If you are using a speaker-level source, simply cut the RCA plugs off of the harness and splice the head unit's speaker wires onto the harness. If you prefer not cutting the RCA plugs off, use the Kicker KiSL speaker level to RCA adapter. The Input Sensitivity is 250mV-10.0V (High Level), while the Low Level Input Sensitivity is 125mV-5.0V.

Differential Audio: The differential audio circuit reduces the likelihood of picking up any engine noise, and helps lower THD (Total Harmonic Distortion).

Weather Resistant: The PXA Amps are weather-resistant, using a conformal-coated circuit board for protection against the elements. They also include no-rust stainless-steel mounting hardware.

Power Wiring: The amp comes with a power and ground terminal adapter that will accept up to 8-gauge wire. Power and ground wire (8-gauge is recommended) can be inserted into the adapter and tightened with a flat or Phillips head screwdriver. The adapter then plugs directly into the amplifier. An in-line fuse holder with a 40A MAXI fuse is included with the amp. No other power or ground wiring is included.

Speaker Output/Turn-on Lead: The speaker output wires and the amp turn-on lead are located on the same plug-in harness. Two pairs of 16-gauge wire are soldered together to form a single positive and a single negative speaker output. The blue turn-on lead should be connected to the amp remote wire on the aftermarket head unit's harness. If you are connecting the amp to a head unit via the speaker-level input, it is not necessary to connect the turn-on lead, as the amplifier with turn itself on when the amp detects a 6V DC signal on the input. You will need to select the proper Auto Turn-On on DIP switch #5 on the bottom of the amp.

Optional CXARC Remote: You can control the output level of the amplifier remotely with the optional CXARC Remote Bass Control. The remote plugs into the 3.5mm mini jack on the end of the amplifier. The CXARC comes with a 19.5' cable that allows you to locate the controls near the driver's location.

Subsonic Filter: The PXA500.1 includes a 24 dB/octave subsonic filter, fixed at 25 Hz. This filter eliminates power-robbing, extremely-low frequencies that most speakers cannot reproduce.
