Frequently Asked Questions - Reference REF-9630cx INFINITY
What is the difference between RMS and peak power handling?
RMS power is the continuous power the speaker can handle safely, while peak power is the maximum burst it can withstand for short moments. For the REF-9630cx, RMS is 50W and peak is 250W.
Can I use these speakers with a factory head unit?
Yes, the 4-ohm impedance and 96dB sensitivity make them efficient enough to work with most factory stereos, though an external amplifier will unlock full performance.
How do I determine correct wiring polarity?
Connect the speaker's positive terminal to the amplifier's positive output and the negative to negative. Reversed polarity causes phase cancellation and weak bass.
What is the recommended amplifier power for best sound quality?
For the INFINITY REF-9630cx, an amplifier delivering 15–50W RMS per channel is ideal. Exceeding 60W RMS may risk damage at high volumes.
Are these speakers weatherproof?
They are designed for car interiors and are not fully waterproof. Avoid direct contact with liquids. Some splash resistance is possible, but prolonged exposure will damage the cone.
How do I clean the speakers?
Use a soft, dry microfiber cloth to gently wipe the cone and surround. Never use water, alcohol, or abrasive cleaners, as they can degrade the materials.
Do the speakers need a break-in period?
Yes, a 10–15 hour break-in at moderate volume is recommended. This loosens the spider and surround, allowing the speaker to reach its optimal bass response.
What are the mounting depth requirements?
The mounting depth is 55 mm (2.18 inches). Check that your door or rear deck provides this clearance; add a spacer ring if necessary to avoid magnet interference.
Can I install these speakers in a custom enclosure?
Yes, they are designed for free-air or infinite baffle use, meaning they can operate in large enclosures or without one. For a sealed box, use a minimum of 0.8 cubic feet (23 L).
What should I do if there is no sound from one speaker?
Check the wire connections at the speaker and amplifier, verify the polarity, and test the speaker with another output. If it still produces no sound, the speaker may be defective and may need replacement.
