MTX Audio RTX Series 150W 8" Midrange Speaker & fitting Accessories to suit Mazda vehicles

This bundle package appears to contain components for upgrading the front speakers in a vehicle, likely a Mazda with a Bose sound system. Let's break down each component:

This bundle package includes the following items:

• MTX Audio RTX Series 150W 8" Midrange Speaker - RTX84 X2 (Pair): The MTX RTX84 midrange is a 20cm (8”) high output loudspeaker. With very little power, it reproduces a lot of sound. These mid-bass drivers handle 150W RMS with an efficiency over 97dB. Intended for SQL installations and open door sound systems. The sound is very powerful and live. It shines with a striking realism, softness and exceptional musicality. Despite its very high efficiency, it is never brutal or aggressive. Its large 38mm coil, its aluminium phase plug to fight against standing waves, its extra large magnetic structure (Ø134mm), its fabric suspension and its pressed paper cone are all assets that help with the sound quality and transducer performance.. 
• Front 8 Inch Speaker Spacers: A pair of high-density ABS plastic spacers designed for Mazda vehicles with factory Bose systems, allowing the installation of aftermarket 8-inch BMW-style woofers in the front doors.  
• Speaker Plug to Suit Mazda : A pair of speaker plug adaptors that convert the factory speaker plugs in various  Mazda vehicles to standard aftermarket terminals, enabling simple plug-and-play installation of new speakers without cutting the original wiring.  
• STP Special Line Bitoplast Tape: A roll of 5mm thick, self-adhesive, anti-squeak and sealing tape (15mm wide x 2m long) for use in vehicle interior trims to eliminate squeaks and provide thermal insulation.
