8-Inch Subwoofer Pair for Car Audio

This pair of 8-inch subwoofers is designed for drivers who want deeper bass in a vehicle or boat. Each unit handles 50 watts RMS and 90 watts peak power at 4 ohms. The two-piece set suits stereo installations that need matching low-frequency response.

Cast-Steel Frame and Kapton Voice Coil

A zinc-coated cast-steel basket resists corrosion while a 1-inch high-temperature CCAW voice coil wound on Kapton handles sustained power. High-roll foam surrounds and paper cones with rubber reinforcement keep cone movement accurate. An advanced airflow cooling system and Kapton aluminium heatsinks dissipate heat during extended play.

Check Impedance and Enclosure Volume

Verify that your amplifier is stable at 4 ohms per channel before wiring. Confirm the available mounting depth and sealed or ported enclosure volume match the driver requirements. Ensure the speaker cutout fits an 8-inch frame and that wiring gauge suits the 90-watt peak rating.

Questions about this item

What impedance does the 8" subwoofer pair present to the amplifier?

Each subwoofer presents a 4-ohm load, so the pair can be wired for 2-ohm or 8-ohm total impedance depending on the amplifier requirements.

What mounting depth and cut-out diameter does each 8" subwoofer require?

The 8-inch frame needs a standard 8" cut-out; allow enough depth behind the panel for the 90 mm magnet and cast-steel basket.

How are the voice coils connected when installing the pair in a car audio system?

Each subwoofer has a single 4-ohm voice coil; wire them in parallel for a 2-ohm load or in series for an 8-ohm load to match the amplifier.
