Common Questions Before You Buy

How much power do they handle?
100W power output with 4 ohm impedance, suitable for most factory and aftermarket car stereos and amplifiers.
Which size should I pick?
Match your existing speaker cutout. 4 inch is common for dash, 5 inch for door, 6.5 inch for door or rear. Measure before buying.
Is it sold as a pair or single?
Each variant is sold as 1 piece (single speaker). Order 2 if you want a stereo pair.
Will they survive Australian summer heat?
Yes. The moisture resistant PP rubber surround and injection molded diaphragm hold up well in hot, humid car interiors.
Do I need an amplifier?
Not required. They work with most car head units, but an amplifier will deliver maximum performance and louder, cleaner sound.
