Wāvtech link300.4mini 300 Watt 4-Channel Amplifier

The Wāvtech link300.4mini is a 300W, four‑channel amplifier engineered for ultra‑compact installs that still demand real power. Bridgeable with built‑in summing, it can drive a component set or a small sub in both aftermarket and OEM‑based systems.

• 300 Watt 4-Channel Amplifier: 50 watts x 4 @ 4 Ω; 75 watts x 4 @ 2 Ω; 150 watts x 2 @ 4 Ω (BTL/bridged). Real‑world: flexible four‑channel performance or higher power from bridged pairs for a sub or dedicated rear channels.
• BTL Small Footprint: Compact chassis (6.4” x 4.5” x 1.65”) fits tight installs while delivering bridging capability for higher single‑load power.
• Variable Hi/Low Pass Crossover: (-12 dB/oct). Real‑world: tailor the frequency range sent to front components or a sub for better integration with your other speakers.
• Built‑In Summing w/ Level Trim Adjustment: Processes factory signals internally so no external processor is required; level trim lets you balance outputs across channels.
• Active Thermal Management: Maintains stable performance and protects the amp under load by actively managing heat.
• Start/Stop System Compatible: Works with OEM start/stop setups to simplify integration without additional wiring.
• Adaptive OEM Load Technology: Optimizes operation for the vehicle’s original electrical load, aiding compatibility with factory systems.
• 40V Input Capability: Accepts hi‑level inputs up to 40V, enabling robust connection to factory radios.
• Differential Balanced Inputs: Reduces noise and interference in automotive wiring, preserving signal integrity.
• Variable Gain Adjustment w/ Clip LED: Fine‑tune output and visibly monitor clipping to avoid distortion.
• Auto Turn‑On via DC‑Offset or Audio Signal Detect: Powers on automatically when a signal is present or a DC offset is detected.
• Locking Detachable Hi‑Level Terminals: Secure, reliable connections suitable for tight installations.
• 4 Gauge Power/Ground Terminals: Supports high‑current power delivery with sturdy wiring.
• Professional Grade Panel Mount RCA’s: Durable input/output jacks designed for clean, behind‑dash wiring.
• Compact Aluminum Chassis w/ Detachable Mounting Tabs: Rigid, lightweight enclosure with flexible mounting options.
• Frequency Response: <10 Hz to >45 kHz (+0/-3 dB) for wide, accurate playback.
• THD+N: <1% at rated power, indicating low distortion under typical use.
• S/N: >86 dBA (1W, 4Ω) for a cleaner signal in automotive environments.
• Input Sensitivity: SPK 1-20 Vrms, 2-40 Vrms; RCA 0.2-5 Vrms, 0.4-10 Vrms.
• Max Input Voltage (SPK): 40 Vrms.

In a real car audio build, the link300.4mini handles four channels of clean amplification or two bridged channels for sub‑level impact, while its built‑in signal management simplifies OEM integrations without adding external processors. The combination of compact size, robust connectivity, and thermal management make it a practical choice where space is at a premium but audio performance cannot be sacrificed.
