Frequently Asked Questions - Kappa 42.5I INFINITY

What is the recommended amplifier power for the Infinity Kappa 42.5I?

The speaker handles 50W RMS and 150W peak. An amplifier delivering 25-75W RMS per channel is ideal for optimal performance.

Can I install the Kappa 42.5I in my car doors?

Yes, it is designed for door mounting. Ensure clearance for the window mechanism and check depth (1-13/16") before installation.

Does the Kappa 42.5I come with a grille?

Yes, a grille is included. For custom-fit models like the 32.5cf, grilles are not included, but the 42.5i comes with one.

Is a crossover required for this speaker?

Yes, an in-line crossover is included and must be used to prevent damage. Do not omit or substitute it.

What is the cut-out diameter for the 42.5I?

The cut-out diameter is 3-5/8 inches (93 mm). Ensure your mounting location matches this size.

Can I use the Kappa 42.5I with a factory stereo?

Yes, but for best results use an external amplifier. The 4-ohm impedance is compatible with most factory head units.

How do I connect the crossover?

Connect the crossover between the amplifier output and the speaker. Wires are keyed and color-coded for correct polarity. The larger terminal is positive (+).

What tools are needed for installation?

Basic tools: screwdriver, drill, wire cutters, utility knife, and protective eyewear. Also need a battery disconnect tool.

Is the Kappa 42.5I weather-resistant?

No, avoid mounting where it can get wet. It is for interior use only.

What is the frequency response of the Kappa 42.5I?

The frequency response is 75 Hz - 21 kHz, suitable for full-range audio reproduction.

INSTALLATION WARNINGS AND TIPS

ABOUT THESE INSTRUCTIONS

Installation of automotive stereo components can require extensive experience with a variety of mechanical and electrical procedures. Although these instructions explain how to install Kappa Series multi-element speakers in a general sense, they do not show the exact installation methods for your particular vehicle. If you do not feel you have the experience, do not attempt the installation yourself, but instead ask your authorized Infinity car audio dealer about professional installation options.

LOUD MUSIC AND HEARING

Playing loud music in an automobile can hinder your ability to hear traffic as well as permanently damage your hearing. The maximum volume levels achievable with Infinity speakers, combined with high power amplification, may exceed safe levels for extended listening. We recommend using low volume levels when driving. Infinity accepts no liability for hearing loss, bodily injury, or property damage as a result of use or misuse of this product.

REAR DECK PRECAUTION

In some cars, fuel tanks may be located directly beneath the rear deck. Before installation, make sure there is adequate speaker basket clearance before considering this location!

ABOUT THE CROSSOVER

Except for the 462.5cfp, each Kappa Series multi-element speaker includes a crossover for in-line connection to an amplifier output and is required for proper operation (see Figure 7 on the next page). The attached crossover wires are keyed and color-coded to aid in correct polarity connections. Do not omit the crossover or substitute another one – doing so will damage the speaker.

INSTALLATION TIPS

• Always wear protective eyewear when using any tools.
- T urn off all audio components and other electrical devices before you start. Disconnect the (-) negative lead from your vehicle's battery.
- Keep speakers in their package until final installation. When moving a speaker, always rest it with the cone or dome facing up. Never use force to install any speaker.
- Check clearances on both sides of a planned mounting surface before drilling any holes or installing any screws. Remember that the screws can extend behind the surface.
- At the installation sites, locate and make a note of all fuel lines, hydraulic brake lines, vacuum lines and electrical wiring. Use extreme caution when cutting or drilling in and around these areas.
- Before drilling or cutting holes, use a utility knife to remove unwanted fabric or vinyl, to keep material from snagging in a drill bit or saw.
- F or door installations, check the clearance with the windows throughout the range of the window's travel, and verify that a mounted speaker will not interfere with the window crank or power window mechanism.
- If mounting speakers elsewhere, check for clearance around rear deck torsion bars, glove box or other structural elements.
- Do not mount speakers where they will get wet.

INSTALLATION

NOTE: The 32.5cf, 462.5cfp and 572.5cf speakers are designed to be installed under factory grilles. Consequently, no grilles are packaged with these models.

NOTE: If you are mounting the 572.5cf in a 6" x 8" location, use the adapter provided.

NOTE: Grip the tab with pliers and bend to detach it from the speaker.
