How to use

Before installation, disconnect the vehicle battery to avoid short circuits. Remove the door panel or rear shelf trim following the vehicle manufacturer’s instructions to access the existing speaker. Disconnect the old speaker wiring and remove any mounting hardware. Fit the BLOW WK525 into the existing speaker cutout, secure with the appropriate screws or brackets, and reconnect the speaker wires observing correct polarity. Reassemble trim panels and reconnect the battery, then test the speaker at low volume to confirm proper operation and polarity.

Usage recommendations

For optimal performance, match the speaker with audio sources rated for 4-ohm loads and avoid exceeding the amplifier’s power limits. If a noticeable mismatch in tonal balance occurs after installing a single replacement, consider replacing the corresponding speaker on the opposite side to maintain stereo imaging. Use proper mounting hardware and ensure the speaker is sealed against the enclosure or vehicle panel to reduce rattles and preserve bass response.
