5 Core Inc. SP-1090 10" Car Speaker 600W

10-inch Car Subwoofer for Audio Upgrade

The 5 Core SP-1090 is a 10-inch car subwoofer designed to improve bass response in a vehicle audio system. It suits drivers who want louder low-frequency output without replacing the entire stereo. Buyers who need a compact component for tight enclosures or a plug-and-play upgrade with built-in amplification should look elsewhere.

Dual Voice Coil and Cast Steel Frame

The speaker uses a dual 8-ohm voice coil configuration with a paper cone and rubber foam surround. A 13 oz Y-30 ferrite magnet and cast steel basket provide structural rigidity. The 90 mm voice coil uses copper-clad aluminium wire on Kapton former for high-temperature operation. Integrated heat sinks and airflow cooling help sustain performance during extended playback.

Check Impedance Wiring and Enclosure Volume

Verify that your amplifier is stable at the final load created by the dual 8-ohm coils wired in series or parallel. Confirm the available mounting depth and internal box volume match the 10-inch frame requirements. Ensure the RMS power rating of 60 watts aligns with your amplifier output to avoid overdriving the cone.
