Zessqaa 4-Channel Car Amplifier — Black Series (MS-905)

The Zessqaa Black Series 4-Channel Car Amplifier (MS-905) is built for drivers who want all four car speakers performing at their full potential — not struggling on the underpowered output of a factory head unit. Why You Need a 4-Channel Amp Every head unit — factory or aftermarket — has a built-in amplifier running at low voltage. At moderate volume, it distorts. A dedicated 4-channel amplifier like the Black Series drives all four door speakers (front and rear) with clean, high-current power. The result: fuller sound, better separation between instruments, and a noticeably more premium audio experience from the same speakers. Why Choose the Black Series 4-Channel Output — powers all four car speakers simultaneously from a single unit 9800W Max Power — headroom for dynamic peaks without clipping MOSFET Power Stage — efficient, low-distortion power delivery even at high output Black Series Body — entirely matte black chassis; only the screw terminals are gold-plated metal Compact Profile — 31 × 24 × 5 cm; fits in a car boot or under the rear shelf Universal Inputs — RCA and speaker-level inputs; connects to both aftermarket and factory head units 1-Year Manufacturer Warranty — direct support from Zessqaa Car Compatibility Universal 12V fitment.

The ZQ-802 drives two channels (typically your front speakers). The Black Series drives all four — front and rear — from a single unit. If you want a complete upgrade for the whole car in one step, the Black Series is the right choice. Can I pair this with a bass tube? Yes, and this is the most popular full-system setup. The Black Series drives your four door speakers while a ZQ-1001BST or ZQ-801BST bass tube handles the low end. Each bass tube has its own built-in amplifier, so no additional channels are needed for bass. Is professional installation required? Professional installation is recommended. Most car audio shops complete a 4-channel amp install in 60–90 minutes. Standard connections: power, ground, remote turn-on, and signal cables to all four speakers.
