What would you like your audio system to do?
We recommend the amplifier around the job it needs to perform — not simply whichever model has the biggest power figure.
Power a subwoofer
A correctly matched mono amplifier delivers controlled bass without relying on headline peak-watt claims.
- Matched RMS power and impedance
- Appropriate power cable and fusing
- Correct gain and filtering
Build a DSP system
DSP gives us control over time alignment, EQ and crossovers to get more from your speaker installation.
- Multi-channel / active systems
- System calibration
- Detailed sound-stage optimisation

Clean sound takes more than high power.
We look beyond wattage. Signal-to-noise performance, amplifier design, impedance, available headroom and correct gain structure all affect the final result. So does the quality of the signal feeding the amplifier.
- RMS output matched to real speaker requirements
- Appropriate input level and gain structure
- Noise and hiss minimised through thoughtful system design
- DSP calibration when installed
- Reliable power, grounding and thermal management

The Garage Audio installation approach
Designed, installed and tuned as one system.
01 · System design
We check the existing head unit, speakers, available space, electrical requirements and your listening goals before recommending equipment.
02 · Safe installation
Power and ground connections, suitable fusing, cable routing, signal integration and secure mounting are considered during installation.
03 · Setup and listening
We verify operation, set gains and filters, then tune available DSP functions and demonstrate the result.

Frequently asked questions
Amplifier questions, answered.
Will an amplifier improve my factory stereo?
It can, particularly when paired with suitable speakers and correct integration. The size of the improvement depends on the factory system, signal quality and how the amplifier is installed and tuned.
Is a more powerful amplifier always better?
No. Suitable RMS power, speaker impedance, distortion and noise performance, reliability and tuning all matter. A poorly matched amplifier can sound worse than a less powerful but better-integrated option.
What is a DSP amplifier?
It combines amplification with digital processing such as equalisation, crossovers and time alignment. This can be especially valuable in complex factory-audio systems.
Can you add an amplifier without changing the head unit?
Often yes. We first assess the factory audio system and the available signal, including whether a suitable interface or DSP is required.
Can amplifier upgrades cause hiss or electrical noise?
Yes, if components or their signal and power integration are unsuitable. Careful product selection, gain structure, grounding and wiring help minimise unwanted noise.
How much does installation cost?
Pricing depends on the amplifier, vehicle, wiring, mounting location, integration and tuning requirements. Send us your vehicle details for a tailored supply-and-install quote.
