Upgrade for factory car audio

These Pioneer TS-A879 coaxial speakers target drivers replacing worn or basic original equipment in standard 3.5" locations. The 2-way design handles full-range duties without extra components, making the set a direct swap for most factory door or dash openings.

Carbon mica cone and PEI tweeter

A 3.5" carbon and mica reinforced IMPP cone woofer pairs with a 21mm PEI hard dome tweeter, while a rubber-rolled surround and aramid fiber damper control excursion. The resin basket fits a 3" cutout with 1-3/8" mounting depth, and lug-type terminals accept bare wire or spade connectors for straightforward wiring.

Replaces basic 3.5" factory drivers

The jump is worthwhile when the original speakers distort at moderate volume or lack treble detail, because the 52Hz–33kHz response and 85dB sensitivity raise both bandwidth and output. Buyers needing deeper bass below 52Hz or higher power than 100W RMS should consider larger component systems instead.

Questions about this item

What frequency range does the 52Hz–33kHz response cover with the inline filter?

The inline filter supports a 52Hz–33kHz frequency response, letting the 21mm PEI hard-dome tweeter handle highs while the 3.5" carbon-mica IMPP cone covers mid-bass.

What cutout diameter and mounting depth does the 3.5" frame require?

A 3" cutout diameter and 1-3/8" mounting depth are needed for the resin basket with custom-fit design.

How do you connect the speaker wires to the lug-type terminals correctly?

Strip the wire, insert it through the lug hole, tighten the screw securely, and observe polarity markings to avoid phase issues.
