## Summary description

BLOW R-87 Blister is a coaxial car speaker designed for in-vehicle audio upgrades. Identified by manufacturer code 30-801#, this speaker fits 8" mounting locations and provides full-range sound in a single unit. It is intended for replacing or upgrading factory speakers to improve clarity and mid/high frequency response in car doors or rear decks.

## Long description

BLOW R-87 Blister is an 8" coaxial car speaker designed to replace or upgrade factory-installed speakers in compatible vehicles. The single-unit design integrates a mid-woofer and a high-frequency driver to deliver full-range audio from one mounting point. Its size and mounting dimensions are intended for standard 8" speaker cutouts found in many doors and rear decks, offering improved clarity and more defined mid and high frequencies compared with typical factory units.
Advantages
The coaxial configuration combines a mid-woofer with a tweeter in a compact assembly, simplifying installation while providing a broader frequency response than a single-cone speaker. The 8" diameter offers a balance between bass presence and midrange detail suitable for small to mid-size vehicle enclosures. The unit is designed for direct replacement in vehicles with matching mounting locations, reducing the need for custom adapters or significant modifications.
Suitable for
Replacing worn or damaged 8" factory car speakers in doors or rear decks
Audio upgrades in compact and mid-size cars where space for speakers is limited
Systems where a simple coaxial solution is preferred over component sets
Key specifications
Speaker diameter: 8 inches
Configuration: coaxial (mid-woofer with integrated high-frequency driver)
Application: in-vehicle car audio, door or rear deck installation
Mounting: designed for standard 8" mounting cutouts
Design goal: full-range response from a single speaker unit
How to use
Install the BLOW R-87 Blister into an existing compatible 8" speaker location following vehicle-specific instructions for speaker replacement. Disconnect the vehicle battery before beginning installation to avoid short circuits. Remove the door panel or rear deck cover as required, disconnect the old speaker wiring, and remove the mounting hardware. Place the new speaker into the mounting cutout, secure it with the appropriate screws, and connect the speaker leads observing polarity. Test the speaker at low volume before reassembling panels and trim to confirm correct operation.
Usage recommendations
For optimal performance, pair the speaker with a head unit or amplifier that matches its power handling and output characteristics. Use proper speaker mounting and sealing to minimize panel vibration and air leaks. If higher bass output is required, consider adding a dedicated subwoofer rather than relying solely on an 8" coaxial unit.
