Replacement speakers for Porsche Boxster/Cayman/911 BR 987/997 with BOSE or ARS sound upgrade

Replacement speakers for Porsche 997/987 for the lower door mounting location, as a replacement for the original woofers with part number 997 645 553 00

The Helix Ci3 W200FM-S2 is significantly more powerful than the factory woofer, has a higher efficiency, and sounds rich and powerful.

This 2-ohm version is suitable for use with the BOSE sound system and our upgrade amplifier, which can thus deliver its maximum power to the bass channels.

Since you have already removed the door panels to replace the speakers, we recommend soundproofing the doors at the same time. You can find the necessary soundproofing material in our speaker accessories category. You will need at least 3x Alubutyl 33856348 and 2x foam mat 33857280. The Alubutyl is glued to the metal, the foam to the inside of the door panel. Videos on soundproofing doors of other makes can be found on the ARS-STUTTGART YouTube channel.
