High Power 2-ohm Prime Voice Coil: These highly efficient 2-ohm coils were designed for greater efficiency and are compatible with most premium factory sound systems to make your vehicle sound better than ever. features a Dual 4-OHM voice coil design, allowing for 2-OHM or 8-OHM impedances
High Damping Butyl Rubber Surround: Butyl rubber was chosen to ensure linear travel throughout the entire frequency range resulting in more bass output and higher efficiency while reducing distortion. Non-resonant Basket Treatment: Each steel speaker basket has been treated with a proprietary resonant damping material making the speaker platform acoustically “dead”.

INSTALLATION EXPERIENCE
Installation of PowerBass Autosound Speakers requires experience with a variety of mechanical and electrical procedures. This manual only provides general installation and operation instructions. If you have any reserva-tions about your installation skills or lack of the proper tools, please contact your local PowerBass Autosound dealer for assistance.
TIPS TO GET THE MOST OUT OF YOUR POWERBASS SYSTEM
Your PowerBass Autosound speakers have been meticulous engineered and designed to handle high power musical reproduction. Despite their rugged construction, it is possible to damage your speaker if they are improperly used. In general, you will hear distortion as a so-called warning before any damage occurs. If you hear distortion in your system, immediately reduce the musical level to the point where the sound retains its clarity.
- Be sure you supply the speakers with enough unclipped amplifier power to drive them properly. (More damage can be done to a speaker by under-powering and clipping your amplifier than any other way!)
- To avoid any possible sound cancellation from the front of the speaker to that of the rear of the speaker, cut a panel of Masonite or MDF to firmly mount the speaker if the vehicle’s original cutout is too big.
- When connecting speaker wires from the amplifier or head unit to that of the speaker itself, pay attention to the polarity of the connection. This will insure optimum sound reproduction and performance.
- Do not mount any speakers or external crossovers where they will get wet.
PREPARING FOR INSTALLATION
NOTE: The tools listed below may be required for proper installation.
- An electric drill with drill bits
- Phillips-head and standard screwdrivers
- Wire strippers
- Crimping tool and needle-nose pliers
INSTALLATION PRECAUTIONS
NOTE: Proceed only if you are a qualified installer otherwise; let your dealer do it.
- Always wear protective eyewear when using tools.
- Turn off all stereo and other electrical devices before you begin.
- Disconnect the (-) negative lead from your vehicle’s battery.
- Keep the speakers in the package until final installation.
- Check to see if there is enough clearance behind the mounting surface before installing the speakers.
- When running speaker wires through sheet metal, be sure to use grommets to properly insulate the wires from metal edges.
- Since these speakers utilize a unique low profile tweeter housing that has minimal tweeter protrusion, original factory mounting cutouts can still be used with the factory grills in many cases.
- These PowerBass Autosound speakers can be used above or below the mounting hole. Typically, your vehicle factory’s speaker cutouts will accommodate these new speakers without any modifications. When the speaker has been correctly installed, there should be no air leaks between the front and back of the speaker.
- For door installations, check the clearance of the window and roll-up mechanisms throughout the entire range of the window’s travel to make sure that all obstacles clear the speaker structure.
- Check the available mounting depth before installing the speaker. Use care when removing factory grills, door panels and factory speakers.
WIRING DIAGRAM

Wiring has been designed to work with multiple impedance requirements. The dual voice coil dsign can be wired into two different configurations depending on the impedance requirement of your OEM amplifier.
Both coils must be wired in one of the above configurations to ensure proper operation of this speaker.

FAQs
What is a good midbass frequency range?
The most significant instruments in our musical libraries fall into the crucial midbass frequency range, which spans 200Hz to 500Hz and includes the voice, cello, viola, brass, tympani, woodwinds, bass, and guitar.
Can subwoofer be used for midbass?
Midbass is not. Only frequencies where sound is non-directional are produced by subs (when crossed across correctly). You can clearly hear the direction of midbass, therefore it is definitely not non-directional.
What’s the difference between mid-range and midbass?
The cone of a mid-range speaker typically has a diameter of 4″ to 6.5″. Mid-bass drivers, a type of speaker similar to a woofer but with a slightly higher resonant frequency (80–100 Hz) and an upper-frequency range to blend in with the tweeter of an audio system, are a related speaker.
What does a midbass speaker do?
They are speakers with a maximum frequency range of 5,000 Hz and a higher frequency range than a typical woofer. A super tweeter, for instance, is a type of loudspeaker made specifically to produce high audio frequencies, typically between 6,000 and 100,000 Hz.
What does MID sound do?
Mids, which are frequencies that range from about 250 Hz to 2000 Hz, are crucial for a natural presentation of sound. This part is where voices and vocals fall, and headphones with an unnatural midrange may make voices sound “off” or distant.
Should bass or treble be higher?
The mids are the middle frequencies, as you would have guessed. Between 200 Hz and 5 kHz, they are all the sounds that fall between the high notes (treble) and low notes (bass). Guitars and pianos are frequently used to create these sounds.
Does more power mean more bass?
Like most things, bass necessitates a comparison of quantity and quality. Better bass is not always accompanied by more bass. The subwoofer in question’s wattage determines its power; a higher wattage indicates a more potent subwoofer.
What affects speaker quality?
Each speaker emits a range of frequencies, some of which are louder or softer than others. The less variation in loudness between frequencies—or, in other words, the flatter the frequency response chart is—the better the speaker quality, presuming that your ultimate goal is accurate audio reproduction.
How do you prevent speaker damage?
Maintain your receiver’s level at least 5–6 dB below its maximum setting. Most receivers have a volume control that ranges from -80dB (silent) to around +16dB. (max). You can normally prevent over-driving the receiver, which could potentially harm your speakers and receiver, by staying below -6dB below that maximum setting.
