Page 1: Owners Manual
XMA-4160IR XMA-5670IR XTREME SERIES MINI AMPLIFIER Owners Manual Please read through this manual to familiarize yourself with your new amplifi er. Should your PowerBass Xtreme mobile amplifi er ever require service, you will need to have the original dated receipt. - Page 2 In the interest of safety, PowerBass USA highly recommends listening at lower volume levels when driving.

Page 3: Technical Features
This amplifier represents the very latest in Class D technology. The XMA Series uses the new IR® (International Rectifier) platform which has been under development for the past several years. IR®, a leader in PWM circuit design, has worked in conjunction with PowerBass engineers to produce more stable power output, minimal RF interference and improved sound quality. -
Page 4: Preparing For Installation
Soldering iron • Electronic (Rosen not Acid Core) Solder INSTALLATION PRECAUTIONS NOTE: Proceed only if you are a qualified installer, otherwise; see your Authorized PowerBass Dealer to professionally install this amplifier. Always wear protective eyewear when using tools. • Turn off all stereo and other electrical devices before you begin. -
Page 5: Mounting The Amplifier
(volume) to maintain operation. For this reason the amplifier should be mounted in a location which will allow air to circulate freely. The compact size of the PowerBass XMA Series amplifier allows greater flexibility in mounting. -
Page 6: Fuse Requirements
FUSE REQUIREMENTS While the panel your PowerBass amplifier incorporates one or more fuses, these do nothing to protect the vehicle from a dangerous short circuit. It is absolutely vital that the main power lead to the amplifier(s) in the system be fused within 18-inches (45cm) of the connection to the vehicle battery. The value of this fuse (or circuit breaker) should be no greater than the sum of the fuses found on all of the equipment being connected to that power wire. -

CONTROL PANEL LAYOUT Fig.2 Panel Layout NOTE: Panel Layout and Controls may differ by model. 1. Line INPUT (RCA) Jacks These RCA style input jacks are for use with source units that have RCA line level outputs. A source unit with a minimum of 250mV is required for proper operation. - Page 8 12. GND (Ground Input Connection) A good quality ground is required for your PowerBass Xtreme amplifier to operate at peak performance. A short length of cable the same gauge as the Power cable should be used to attach the Ground terminal directly to the chassis of the vehicle.
- Page 9 Remember, bigger wire is better! For best results we recommend a PowerBass ampli- fier install kit, available at your local PowerBass dealer.

Page 10: Power Wiring
These amplifiers are designed to work within a 10 to 16 volt DC range. Before any wires are connected, the vehicles electrical system should be checked for correct voltage supply with the help of a voltmeter. First, check the voltage at the battery with the ignition in the OFF position. The voltmeter should read no less than 12V. - Page 11 Secure the ground cable to the body using a bolt, star washer and nut. Spread silicon over the screw and bare metal to prevent rust and possible water leaks. NOTE: The Ground must be capable of carrying the same amount of current as the positive wire. Now it’s time to connect the power and ground cables to the amplifier.

Always use high quality RCA audio cables (not supplied) for signal connections—those with multiple layers of shielding or a twisted pair variety for better noise rejection.

RCA INTERCONNECTS Fig.5 Low Level Input using RCA Choose the correct length and style of RCA interconnects for your needs. Always use high quality RCA audio cables (not supplied) for signal connections—those with multiple layers of shielding or a twisted pair variety for better noise rejection. - Page 14 Single RCA OUT Single RCA Output on the Radio (Rear only) In the event the car radio (head unit) you are using Y adaptors has only 1-set of RCA preamp outputs, you will need to split the signal using “Y” adaptors on the Right and Left channels as shown above.
- Page 15 Three RCA OUT (Front and Rear plus Subwoofer) Three RCA Outputs from the Radio (Front and Rear plus Subwoofer) This is the optimum configuration for this amplifier by providing 3-sets of discrete signal to the preamp. It will also offer the most flexibility in tuning the system.

SET UP ADJUSTMENTS INPUT Gain Adjustment GAIN Input Sensitivity Control Fig.6 GAIN Control This control allows you to match the input level of the amplifier to the output level of your head unit. Matching the input can be accomplished in three simple steps: Set the volume of GAIN on the amplifier to Min (completely counter clock wise). - Page 17 25Hz 250Hz Fig.9 Low Pass Control (LPF) LPF (Low Pass Filter) Adjustment Using this volume, adjust the LPF frequency for your subwoofer speaker(s) operation. The X-OVER switch position should be at “LPF”. INPUT MODE INPUT Fig.10 2 - 4 Channel Input Mode Input Mode Switch (XMA-4160IR ONLY) Matches the input from the Source Unit to that of the amplifier, either 2 or 4 Channel.

SPEAKER WIRING AND CONFIGURATIONS Speaker Load Keep in mind your PowerBass Xtreme amplifier is a high power amplifier and not a high current amplifier. In other words this amplifier requires a minimum impedance of 2 ohms STEREO and 4 ohms bridged MONO to operate trouble free. - Page 19 Speaker Output Connections 2 Channel Model ( XMA 2160IR 2-Channel Speaker Output Connection Fig.11 2-CH Speaker Connection (Do not connect total impedance under 2 ohms) 1-Channel (Bridged Mode) Speaker Output Connection SWITCH POSITION X–OVER SUBWOOFER 4 Ohms Minimum Fig.12 1-CH (Bridged Mode) Speaker Connection (Do not connect total impedance under 4 ohms)
