Goldhorn Winter Sales Event

4.8/5 Average Rating
QUICK DEFINITION
Goldhorn is a premium car audio manufacturer specializing in "All-in-One" DSP amplifiers that integrate high-resolution audio players directly into the signal processor. Unlike standard DSPs that rely solely on external head unit signals, Goldhorn units feature native DSD (Direct Stream Digital) playback and proprietary "Voltage Build-Up" Class AB amplification, delivering audiophile-grade dynamics and clarity without the need for complex, multi-component stacks.

Goldhorn Winter Sales Event Buying Guide

Goldhorn DSP
Goldhorn DSP
Factory audio systems use aggressive equalization and limiters to protect cheap speakers, leaving your music sounding flat and lifeless. The Goldhorn Holiday Sales Event is your opportunity to bypass these limitations. By combining a lossless media player, a multi-channel DSP, and high-fidelity amplification into a single chassis, Goldhorn restores the detail and soundstage depth lost in modern vehicle integration.

Choosing the Right Goldhorn Solution

The Goldhorn lineup is segmented by channel count and source capability. The DSPA 406 is the "Entry-Professional" choice, designed for 2-way active front stages or simple 4-channel upgrades. It retains the warm Class AB architecture but keeps the DSP channel count to six.

Stepping up to the DSPA 810 Pro opens the door to 3-way active systems. With 8 channels of amplification, you can power tweeters, midranges, and midbass drivers individually, while still having DSP channels left over for a subwoofer. At the top of the food chain, the P2 DSPA Pro isn't just an amplifier; it is a high-resolution source unit. It features a built-in DSD player that reads files directly from USB, bypassing your factory radio entirely for a pure, uncolored signal path.

Technical Features & "Voltage Build-Up"

Most compact DSP amplifiers use Class D topology to save space, often sacrificing high-frequency smoothness. Goldhorn distinguishes itself by using Class AB amplification in the 406 and 810 Pro series, aided by proprietary "Voltage Build-Up" technology. This internal power supply management allows the amp to swing higher voltages than standard 12V rails typically allow, resulting in higher headroom and punchier dynamics without the harsh digital glare of cheaper Class D chipsets.

Installation Advice

Because Goldhorn units (specifically the 406 and 810 Pro) utilize Class AB architecture, they run warmer than standard Class D mini-amps. When installing, ensure the mounting location—typically under a seat or in a trunk rack—has at least 1-2 inches of air gap for ventilation. Do not bury these units under carpet or in closed foam blocks. For the P2 DSPA Pro, because it acts as a high-res player, we recommend routing the USB controller cable to the center console for easy access to your music library.

COMPARING MODELS
Series / Model Best Application Sound Profile Power / Channels
DSPA 406 2-Way Active Front Stage Warm, Analog (Class AB) 4 x 65W (Max)
6ch DSP Processing
DSPA 810 Pro 3-Way Active + Rear Fill Dynamic, High Headroom 8 x 65W (Max)
10ch DSP Processing
P2 DSPA Pro Competition / Source Replacement Reference Grade (DSD Native) 8 x 80W (Max)
16ch DSP + DSD Player
INSTALLER'S TAKE

When tuning the P2 DSPA Pro, always tune your "Player" input EQ separately from your "High-Level" input EQ, as the factory radio signal often requires aggressive de-equalization that the pure DSD signal does not.

Frequently Asked Questions

What is the difference between the Goldhorn DSPA 406 and 810 Pro?

The primary difference is channel count and system capability. The DSPA 406 has 4 amplified channels and 6 DSP channels, making it ideal for 2-way active systems. The DSPA 810 Pro features 8 amplified channels and 10 DSP channels, allowing for fully active 3-way systems plus rear speakers or a subwoofer.

Does the P2 DSPA Pro replace my factory radio?

It does not physically remove your factory radio, but it can replace it as your primary music source. The P2 DSPA Pro has a built-in high-resolution player that reads files from a USB drive, allowing you to bypass the factory radio's inferior audio signal for critical listening.

Do I need a separate amplifier for a subwoofer with Goldhorn DSPs?

Yes. While these units have powerful internal amplifiers for door speakers and tweeters, they are not designed to drive high-power subwoofers. All three models (406, 810 Pro, P2) feature RCA outputs specifically to send a processed signal to a separate dedicated subwoofer amplifier.

What is Goldhorn "Voltage Build-Up" technology?

Voltage Build-Up is a proprietary internal power supply design used in Goldhorn's Class AB amplifiers. It boosts the internal rail voltage, allowing the amplifier to produce higher clean power and dynamic peaks than standard amplifiers of the same size, resulting in a punchier, less compressed sound.

Are Goldhorn DSP amplifiers Class D or Class AB?

Goldhorn uniquely uses Class AB topology for many of its amplifiers, including the DSPA 406 and DSPA 810 Pro, to prioritize sound quality and warmth. The P2 DSPA Pro utilizes a high-efficiency design to manage its higher channel count and power output.
