Product Overview
The Rockford Fosgate Prime R168X2 is a 6"×8" oval 2-way full-range speaker rated at 55W RMS the highest RMS rating in the Rockford Fosgate Prime speaker range represented in this catalogue.

Features & Benefits
-
55W RMS — Highest in the Prime Speaker Range — At 55W RMS, the R168X2 handles 10W more continuously than the 6.5" and 6.75" Prime models — providing greater headroom for amplified installations and suiting it to the output of low-powered 4-channel amplifiers without requiring conservative gain settings.
-
6"×8" Oval Format — The 6"×8" oval format is a common OEM speaker size in Ford Falcon, Ford Focus, Ford Territory, Mazda 3, Mazda 6, and numerous other models where a standard round speaker will not fit. The larger oval cone area provides similar or better low-frequency output to a 6.5" round speaker while fitting the specific oval cutout of these vehicles.
-
Silk Dome Flush-Mounted Tweeter — Smooth, warm high-frequency response from a soft silk dome tweeter — the same tweeter technology as the R14X2, R1525X2, and R1675X2, delivering consistent, non-fatiguing highs without the forward character of a Piezo design.
-
Integrated Tweeter Crossover — Built-in crossover included in the kit — no external crossover required. Connects directly to factory speaker wiring.
-
Vacuum Polypropylene Cone, Rubber Surround — Proven moisture-resistant construction for long-term reliability in Australian vehicle conditions.

Frequently Asked Questions
Is the 6"×8" format the same as a standard 6.5" speaker?
No. The 6"×8" is an oval speaker format with a specific non-round cutout shape. It is not interchangeable with 6.5" or 6.75" round speaker positions without an adaptor. Confirm your vehicle's OEM speaker size and cutout format before purchasing.
Are grilles included with the R168X2?
The supplier description does not mention grilles for the R168X2 — unlike the other Prime series speakers which all confirm grille inclusion. Confirm whether grilles are included with Rockford Fosgate or your authorised reseller before purchasing if grilles are required for your installation.
Is the R168X2 sold as a pair or single speaker?
The supplier description refers to a "kit" with integrated crossovers and mounting hardware — suggesting a pair, consistent with the "X2" SKU suffix on other Prime models. However, pair status is not explicitly confirmed for the R168X2. Confirm with Rockford Fosgate before purchasing.
What vehicles commonly use a 6"×8" oval speaker?
The 6"×8" oval format is common in Ford Falcon, Focus, Territory, Mazda 3, Mazda 6, and a range of other Ford and Mazda platform vehicles. Always confirm your specific vehicle's speaker size using the owner's manual, a vehicle-specific fit guide, or a Rockford Fosgate fit guide before purchasing.
Does the R168X2 need an amplifier?
The 55W RMS rating is compatible with aftermarket head unit output, though sensitivity is not confirmed — confirm the sensitivity spec from the Rockford Fosgate datasheet to assess head unit compatibility. An amplifier from the Rockford Fosgate T series 4-channel range will maximise the speaker's performance headroom.
