Frequently Asked Questions - S-6903 PowerBass
How do I install the PowerBass S-6903 speaker?
Disconnect the car battery, remove the door panel or trim, take out the old speaker, connect the wiring harness to the new speaker ensuring polarity, mount with screws, and test before reassembly. Use included mounting hardware.
Can I use this speaker without an external amplifier?
Yes, the S-6903 operates with any standard head unit, but for best performance it is recommended to pair it with an aftermarket amplifier delivering up to 100 watts RMS per channel.
What is the difference between 2-way and 3-way speakers?
A 2-way speaker has a woofer and tweeter, while a 3-way adds a midrange driver for more focused vocals and smoother frequency response. The S-6903 is a 3-way design.
How do I get the best bass from my S-6903?
Ensure the speaker is securely mounted in a sealed enclosure or door cavity, apply sound deadening material, and use proper crossovers. The speaker's frequency response extends to 30 Hz, but external subwoofers are recommended for deep bass.
What is the recommended crossover setting?
For a high-pass filter, set it to about 60-80 Hz. The tweeter is fixed, but the low-pass for full-range can be set at 20 kHz.
Can I use the S-6903 in a marine environment?
No, the S-6903 is not marine-certified. Keep it away from moisture to avoid damage.
How do I clean the speakers?
Gently wipe the grille and frame with a soft, dry cloth. Do not use liquids or cleaners on the speaker cone.
What is the peak power handling vs RMS?
Peak power is 300 watts for short bursts, and RMS (continuous) is 100 watts. Exceeding RMS for long periods can damage the speaker.
Does this speaker fit my car?
The S-6903 fits standard 6x9-inch mounting openings. Measure your existing speaker's cutout dimensions (5.5" x 7.5") to confirm.
What should I do if the sound is distorted?
Reduce the volume or gain, check wiring polarity, and ensure the head unit output is clean. Also verify that the speaker's mounting is airtight.
