Factory Stereo Upgrades for your 2013 Compass

When you want to add subwoofers or high-end speakers to a factory system, you need more than just a standard wire splice. Our selection of factory stereo upgrade components ensures that your new gear communicates perfectly with your vehicle’s existing computer systems.

Line Output Converters (LOCs)

Line output converters (LOCs) take the high-level signal meant for your factory speakers and convert it into a low-level RCA signal that an aftermarket amplifier can use.
We carry everything from basic two-channel converters to advanced units from brands like AudioControl, which feature "AccuBASS" to counteract the bass roll-off often programmed into factory stereos.

Digital Signal Processors (DSP)

Factory radios are often tuned to protect cheap paper speakers, resulting in a "flat" or muddy sound. A Digital signal processor (DSP) allows you to take complete control of your acoustic environment.

By using a DSP, you can sum signals, eliminate factory EQ curves, and adjust time alignment so that the music reaches your ears perfectly, regardless of where the speakers are placed.

Vehicle-Specific Interfaces & Harnesses

Cutting into your factory wiring can void warranties and cause electrical headaches. We offer plug-and-play harnesses and interfaces from leaders like iDatalink Maestro and PAC.

These modules allow you to add aftermarket amplifiers while retaining steering wheel controls, factory chimes, and even OnStar or SYNC features.

Why Upgrade Your Factory System?

By integrating high-quality aftermarket amplifiers and speakers into your existing setup, you gain:

• Increased Headroom: Play music louder without distortion
• Full Range Sound: Restore the deep low-end frequencies that factory systems often filter out to protect small speakers
• OEM Aesthetics: Keep your interior looking exactly as the manufacturer intended while enjoying a "stealth" high-end audio system
