The SA-5ChLH delivers 1100 watts RMS and up to 2000 watts peak power across five channels, making it the complete solution for powering your entire car audio system. This Class D amplifier handles front and rear speakers plus a dedicated subwoofer channel with the efficiency and clean power delivery that serious car audio enthusiasts demand.

Built around a MOSFET power supply, this amplifier produces clean, distortion-free power with less than 0.2% THD across a 10Hz to 25kHz frequency response. The Class D design maximizes efficiency while minimizing heat, ensuring consistent performance during long listening sessions.

The SA-5ChLH offers complete tuning control with independent gain controls, high-pass and low-pass filters, subsonic filtering from 10-55Hz, and 0-12dB bass boost. High-pass filtering ranges from 40-400Hz while low-pass covers 50-250Hz, giving you precise crossover points for optimal speaker matching. Input sensitivity adjusts from 0.25-4.5V to work with any head unit.

This amplifier handles complete system builds from daily drivers to competition setups. The five-channel configuration eliminates the need for multiple amplifiers, while thermal protection and LED status indicators ensure reliable operation. Both high and low-level inputs accommodate factory or aftermarket head units.

Standard RCA inputs connect directly to most head units, while the high-level inputs work with factory systems without additional adapters. The compact 11.75" x 9" x 2" footprint fits in tight installation spaces.

Seismic Audio backs the SA-5ChLH with professional-grade construction and fast shipping to get your system powered up quickly.

Technical Specifications

Frequently Asked Questions

Can this amplifier power my entire car audio system?

Yes, the SA-5ChLH's five-channel design lets you power front speakers, rear speakers, and a subwoofer with a single amplifier. With 1100 watts RMS total power and independent channel controls, it eliminates the need for multiple amplifiers in most complete system builds.

What cables do I need to connect this amplifier?

You'll need RCA cables from your head unit to the amplifier's inputs, plus speaker wire to connect each channel to your speakers. The amplifier includes both high and low-level inputs, so it works with factory head units (using high-level inputs) or aftermarket units (using RCA inputs) without additional adapters.

How does the Class D design benefit my car audio system?

Class D amplifiers like the SA-5ChLH operate with much higher efficiency than traditional Class AB designs, generating less heat and drawing less power from your electrical system. This means cleaner sound, longer component life, and less strain on your alternator during high-volume listening.

What's the difference between the 1100W RMS and 2000W peak ratings?

The 1100W RMS rating represents continuous clean power output at 2-ohm stereo operation, while 2000W peak is the maximum instantaneous power during musical peaks. RMS power determines your system's overall volume capability, while peak power handles dynamic musical content without distortion.

Will this amplifier work with my factory radio?

Yes, the SA-5ChLH includes high-level inputs that connect directly to factory speaker wires, eliminating the need for line output converters. The adjustable input sensitivity (0.25-4.5V) ensures proper gain matching with any head unit, factory or aftermarket.
