Sold by AudioSellerz.com

The SoundQubed 1600 Watts F4-1600 Full Bridge 4 Channel Amplifier is a SoundQubed four-channel speaker amplifier for a system built around the exact power ratings, impedance limits, channel layout, wiring, and electrical requirements listed below.

Use the model name F4-1600 when comparing SoundQubed amplifiers. Do not choose an amplifier from the largest wattage number alone; match continuous output at the intended load, the connected speakers or subwoofers, power and ground wire, fuse protection, battery support, alternator capacity, airflow, and gain settings.

Original Product Details and Specifications

SoundQubed F4-1600 1600W Full-Bridge 4-Channel Amplifier

The SoundQubed F4-1600 full-bridge 4-channel amplifier delivers serious power for mids, highs, component speakers, pro-audio doors and other full-range car audio systems. With up to 400 watts RMS across four channels at 2 ohms, the F4-1600 gives customers a powerful multi-channel amplifier in a compact chassis that is easier to fit into crowded amp racks and tighter installations.

The SoundQubed F4-1600 can also be bridged to produce 800 watts RMS across two channels at 4 ohms. This gives installers additional flexibility when powering larger speakers or building a two-channel system that requires more power per channel.

Audio Sellerz started selling SoundQubed in 2024, and we quickly realized we should have carried the brand sooner. The F4-1600 is a strong example of why: useful power, flexible channel options, full-range capability and a compact full-bridge design that can fit several different kinds of car audio builds.

Powerful 4-Channel Amplifier for Mids and Highs

The SoundQubed F4-1600 4-channel amplifier is a strong choice for systems that need considerably more speaker power than a factory radio or normal aftermarket head unit can provide.

It can be used to power equipment such as:

Four upgraded coaxial speakers
Front and rear component speaker systems
High-power midrange speakers
Pro-audio door speakers
Custom speaker pods
Mids and highs in loud daily-driver systems
Speakers that need to keep up with a powerful subwoofer stage

250 Watts x 4 at 4 Ohms

At 4 ohms, the SoundQubed F4-1600 produces 250 watts RMS through each of its four channels.

This configuration can work well for four 4-ohm speakers that can safely handle the amplifier’s output. It gives customers separate control over four channels while providing significantly more power than most radios can deliver.

Before connecting speakers, verify the speaker impedance, RMS power handling and crossover requirements. Do not match the amplifier using peak or maximum-power numbers alone.

400 Watts x 4 at 2 Ohms

At 2 ohms, the F4-1600 produces 400 watts RMS per channel.

This configuration is useful for high-output speaker systems that need more power per channel. Depending on the speakers and wiring plan, each channel may power a compatible 2-ohm load created by one speaker or multiple speakers wired together.

Before wiring multiple speakers to one channel, calculate the final impedance carefully. The final load should not be lower than the amplifier’s rated 2-ohm stereo capability.

800 Watts x 2 Bridged at 4 Ohms

The SoundQubed F4-1600 can also produce 800 watts RMS x 2 channels when bridged at 4 ohms.

Bridging combines two amplifier channels to provide more power through one output. This can make sense for a system using two larger 4-ohm speakers or another compatible two-channel configuration that needs considerably more power per speaker.

When bridging the amplifier:

Use only the correct bridged speaker terminals
Keep each bridged load at 4 ohms
Verify that the speakers can safely handle the available RMS power
Set the crossovers for the type of speaker being powered
Set gain correctly instead of treating it like a volume control

Compact Full-Bridge Amplifier Design

The F4-1600 measures approximately 9.13" long x 8.46" wide x 2.28" tall. Its compact footprint gives installers more flexibility when mounting the amplifier beneath a seat, on an amp rack, behind a panel or in another space-conscious installation.

The smaller chassis can be especially useful in:

Pickup trucks
Compact cars
Hatchbacks
Motorcycle or powersports builds when the installation is appropriate
Multi-amplifier systems with limited rack space
Custom door-speaker systems

Compact does not mean the amplifier should be installed without ventilation. Leave enough room for airflow and avoid mounting the amp against carpet, loose material or areas exposed to moisture.

Full-Range 10Hz–20kHz Frequency Capability

The SoundQubed F4-1600 has a listed frequency range of 10Hz to 20kHz, allowing it to operate as a full-range amplifier.

That makes it suitable for mids, highs, coaxial speakers, component speakers and pro-audio equipment when the crossover settings are matched correctly to the connected speakers.

The amplifier also includes a 10x crossover frequency multiplier, giving installers additional crossover adjustment flexibility for different speaker systems.

Crossovers are important because speakers should not be forced to reproduce frequencies outside their intended range. Tweeters need protection from low frequencies, while midrange and midbass speakers should be crossed according to their specifications and installation.

Who Should Buy the SoundQubed F4-1600?

The F4-1600 may be a strong choice for customers building:

A high-power four-speaker system
Amplified front and rear doors
A component speaker system
A custom pro-audio door build
A mids-and-highs system that needs to keep up with serious bass
A two-channel bridged speaker system
A compact multi-amplifier installation
A complete SoundQubed amplifier and speaker setup

Match the F4-1600 With the Correct Speakers

The SoundQubed F4-1600 should be matched to speakers according to three main factors:

Speaker impedance: Determine the final load connected to each channel
RMS power handling: Match the speaker’s real power capability to the amplifier output
Frequency range: Set high-pass and low-pass crossovers correctly

A speaker rated for 100 watts RMS should not automatically be connected to a channel capable of producing 400 watts RMS without careful gain setting and system planning.

At the same time, buying strong speakers and severely underpowering them can limit the output the customer expects. The goal is a properly matched system with clean signal, correct crossovers and accurately set gain.

Power Wire, Ground Wire and Fuse Protection

A 1600-watt amplifier needs proper power and ground wiring. Do not choose the amp kit only by what fits into the terminals or what costs the least.

The installation should include:

Correctly sized power wire
A matching ground-wire size
A short, clean and secure amplifier ground
Proper battery-side fuse protection
Secure terminals and connections
Safe routing through the vehicle
A charging system capable of supporting the complete audio system

Browse available car audio amp kits and amplifier wiring kits before installing the F4-1600.

Our car audio wire gauge and fuse guide explains how wire size, OFC versus CCA, amplifier power, run length and fuse protection work together.

Build a Strong Amplifier Ground

The ground cable should normally match the power-wire gauge and conductor type. A large power cable cannot overcome a weak or undersized ground connection.

The amplifier ground should be:

As short as practical
Connected securely to clean bare metal
Protected against loosening and corrosion
Large enough for the amplifier’s current demand
Kept away from weak factory brackets or thin sheet-metal connections

Read our car audio amplifier grounding guide before completing the installation.

Does the F4-1600 Need Electrical Upgrades?

The electrical upgrades needed depend on the entire system, not only this amplifier.

A vehicle running the F4-1600 along with a large monoblock subwoofer amplifier may need more electrical support than a vehicle using the F4-1600 by itself.

Possible upgrades can include:

A Big 3 wiring upgrade
A stronger starting battery
Additional battery capacity
A high-output alternator
Upgraded charging and grounding cables

Review the step-by-step car audio electrical upgrade guide when planning the rest of the system.
