General Specifications

Built-in Crossover

A crossover is a type of filtering system that permits only certain frequencies to play. A Low-Pass (LP) crossover allows only frequencies below its setting to get through which is good in the case of some subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, this is normally used on speakers.

When a crossover is set to FULL it means no filtering is added and the full frequency spectrum is allowed through the amplifier. Filtering is important because feeding a speaker frequencies it cannot reproduce effectively creates distortion.

High-Pass (HP)
Built-in Bass Reconstruction
Bass reconstructors, or bass enhancers, improve low frequency reproduction in a car audio system with at least one subwoofer. These bass expander products will help your subs produce accurate bass thumps.
Line Driver
A line driver is a small amplifier used to support the strength of the audio signal coming from the source unit.
Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
Total Number of Inputs
This is the total number of input connections that go into the unit.
Total Number of Outputs
This is the total number of output connections that the unit will produce.
Max Output Level
The maximum level (in volts) of signal output. A higher level will increase the clarity and boost your signal.
9 volts
The width of the item from left to right (side-to-side) measured in inches.
The height of the item, measured from top to bottom, in inches.
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.

Why did you choose this?
Sonic Electronix Store
My Fusion Marine stereo had only one preamp output. This will reduce amps before the 400 watt Alpine amp.
Gary C on Mar 11, 2015
Both a Line Out Converter and a High Pass Filter in a package small enough to fit behind the dash. Clean up the signal to the amp and cut those nasty low notes to the interior speakers (I have a sub). Win-win.

Would this allow me to hook up an aftermarket amp and sub to my 98 Expeditions factory head unit and cd changer?
A shopper on Jan 30, 2015
Best Answer: Hello,

Yes. The intended use of a 'High Low Converter' (aka Line Out Converter [LOC]) is to tap into OEM wiring to the provide you with Usable 'Low Level Outputs' (aka RCAs) for the addition of an aftermarket amplifier. Please plan accordingly if you are looking to do this install yourself.
