About the PAC LPA-2.2 LocPro Advanced

Hook into your car's factory system
Hook into your car's factory system
One of the best ways to add an amplifier or powered subwoofer to a factory system is with a line output converter (LOC), which reduces the factory system's high-level outputs down to the preamp-level signals your aftermarket amp can handle. PAC's LPA-2.2 LocPro Advanced line output converter will work with just about any factory system, even amplified premium systems, to help you add an aftermarket amplifier in your vehicle.
Features for adding a sub
The LPA-2.2 active line output converter lets you add an amp without affecting the existing factory system — you just tap into the wires going to a pair of full-range speakers for the LPA-2.2's inputs. Selectable load resistance and ground isolation options ensure trouble-free OEM integration. A gain control with a clip light adjusts the signal level for optimum strength and fidelity. A low-pass filter and bass boost fine-tune the bass to sound its best. An optional wired remote is available, so you can control the bass level from your front seat.
Boosting two channels
The 2-channel LPA-2.2 can also be used when adding a 2-channel amp to upgrade the power of your sound system's front stage, for example. PAC offers vehicle-specific T-harnesses that'll greatly simplify installing this LOC in a select number of vehicles with non-amplified factory stereos.

Features
Overview: The LPA-2.2 is an active 2-channel line output converter designed for adding an aftermarket amplifier to a factory radio. There is one pair of speaker level inputs, compatible with most factory stereo systems, that will accommodate up 40 volts per channel (equivalent to 400 watts at 4Ω) and one pair of stereo RCA outputs.
Connections:
- Power: removable 4-pin Phoenix terminal;
accommodates bare wire up to 12-gauge
- +12 volts: fused constant +12 volt source (neither a fuse nor a fuse holder is included)
- Ground: chassis ground
- Remote In: unit turns on when +12 volts is applied to this terminal
- Remote Out: +12 volt output when unit is on (used to turn on an amp)
- Speaker Level Inputs: removable 4-pin Phoenix terminal; accommodates bare wire up to 12-gauge
- Line Outputs: one pair of stereo RCA jacks
- Remote: RJ-14 jack for an optional wired remote control; item number 541LPAREM (sold separately)
Clip Indicator: An LED indicates when the output signal is too high and is clipping, making it easy to maximize the output levels without distortion.
Controls:
- Load Select: 3-position switch; 20Ω, 60Ω, or 20kΩ; use the lower settings to simulate a speaker load if required by the factory radio
- Low Pass Filter: 2-position switch; on/off; a 250 Hz low pass filter can be engaged
- Bass Boost: rotary dial; 0-12 dB; when the low pass filter is engaged, bass boost can be added; centered at 45 Hz
- Gain: rotary dial; -27.3 to +3.2 dB range
- Ground Isolation: 3-position jumper; Ground, ISO (isolated), or 200Ω; change the position in the case of ground loop noise
Specifications:
- Maximum Input Voltage: 40 volts/400 watts at 4Ω (using the 20kΩ input impedance)
- Maximum Output Voltage: 9.5 volts RMS
- DC Offset Range: 3-7 volts
- Input Load: 20Ω, 60Ω, or 20kΩ
- Output Impedance: <120Ω
- Output Gain: -28 dB to +1 dB
- Signal to Noise Ratio: >110 dBA at 6.4 volts output
- THD+N: <0.01%
