The Bass Master Commands You!
Please inspect each loudspeaker carefully. Notify your Polk Audio dealer if you notice any damage or missing items. Keep the carton and packing material. They will do the best job of protecting your speakers if they need to be transported.
Important Information About Warranty & Installation
Subwoofers work best when installed in an enclosure of the proper size. Recommended subwoofer enclosure sizes are provided in the table below. For custom subwoofer enclosures visit http://www.polkaudio.com/car/toolbox/subboxplans.
Recommended Enclosure Sizes:
10" Subwoofer — 0.66 ft
3
sealed
12" Subwoofer — 0.88 ft
3
sealed
Be careful. Subwoofer enclosures need to be installed in places where they can operate safely and not endanger the occupants of the automobile. Do not install your subwoofer enclosure on your car’s rear deck. Do not install your subwoofer enclosure on your front dashboard or in your passenger seat. To get the safest, best performance from your Polk/MOMO
Subwoofer, we recommend that you put its enclosure in your trunk. If you have any questions about these issues, please call Polk Audio’s friendly Customer Service Department.
Polk Audio Customer Service is available from 9am—6pm, EST, Monday through Friday, at 800-377-7655 (US & Canada only), outside the US please call 410-358-3600.
Connecting Your Polk/MOMO Subwoofers
5-way binding post connectors are located on the back of the subwoofer. For a bare wire connection, strip 1/2 inch (12.7mm) of insulation from each of the two conductors of your wire to expose the bare metal and twist each of the conductors into a single unfrayed strand
(so you have two unfrayed strands). Note that one of the terminals on the woofer is red (+) and the other is black (-). Make certain that you connect the wire from the red terminal of your amplifier to the red terminal on the woofer and the wire from the black terminal of your amplifier to the black terminal on the woofer. Most wire has some indicator (such as color-coding, ribbing or writing) on one of the two conductors to help you maintain consistency. To connect bare wire to the binding post, unscrew the nut and insert the bare wire into the hole near the base of the binding post. Do not insert the insulated part of the wire into the hole as this will not give you a good connection. Twist the nut back down the binding post until it firmly meets the wire. Do not over tighten.

Parallel 2Ω Wiring
Two 4Ω speakers will present a 2Ω load.
Make sure that your amplifier is 2Ω stable when configured in the bridge mode.
Consult your amplifier’s owner’s manual before wiring in this configuration.
Break It In
Your Polk/MOMO Subwoofer will achieve even greater performance once it is thoroughly broken-in. To break in your new sub, play 20 to 30 hours of music at moderate levels. Get more information online at Polk University: http://www.polkaudio.com/car/faqad/index.php
Amplifier Power Requirements For Polk/MOMO Subwoofers
With one subwoofer we recommend an amplifier with a power rating of at least 200-
Watts (x 1 in bridged mode) to sufficiently drive this woofer. If you have a noisy car or intend to play your system at loud listening levels, more power is necessary to achieve the best performance. More power is always better. Consult your Polk Audio dealer for specific recommendations.
Optimal Crossover Setting
We recommend using an active crossover with a 12 to 18dB per octave low pass filter slope, and setting it to an initial setting of 80 to 90 Hz as a good starting point. This is an optimal crossover setting on most vehicles.
Inverting Phase
Depending on the placement of your subwoofer enclosure and associated components, it may be necessary to invert the phase of one or another of your system’s connections in order to gain better subwoofer/mid-range blending. Inverting the phase simply means switching the positive connections with the negative connections at the amplifier. If you choose to do this, invert the phase of only one set of speakers (either your mains, or your subs, never both).

Safe Limits Of Operation
Your Polk/MOMO Subwoofer is made with the highest quality materials for years of troublefree performance. However, damage to loudspeakers can occur when an amplifier, regardless of its wattage, is made to play at higher listening levels than its power can clearly produce (usually beyond the “1 to 2 o’clock” position on the volume control). This results in very high levels of audible distortion, originating in the amplifier, which adds a harsh, gritty sound to the music. Contrary to popular belief, a speaker is more likely to be damaged by trying to get too much volume from a low-powered amp than from a high-powered one.
Hear distortion? Turn it down. Contact Polk Customer Service 800-377-7655 (9am—6pm,
EST, Monday through Friday).
Low Frequency Cut-Off For Mid-Range Speakers
In Systems With Subwoofers
Now that you have a subwoofer in your system, you may want to decrease the amount of bass going to your mid-range speakers. This will get you better mid-range sound and increase the power handling. There are two ways to roll off the bass before it gets to your mid-range speakers. One way is to use a “bass blocker,” a capacitor placed in series with the speaker input. Bass blockers are installed in series, one end connected with the positive lead from your amplifier and the other end connected to the positive lead of each of your speakers. Bass blocker capacitors (200 microfarad @ 100volts, non-polarized) are available at any RadioShack or parts supply house. The other route is to use an electronic crossover device that allows filtering below 100Hz or so. Find these devices at your authorized Polk
Audio dealer.

Tech Assistance Or Service—Not Hearing Anything? Read This:
If, after following these hookup and installation directions, you experience difficulty, please double-check all wire connections.
Make certain your electronic equipment is operating correctly by hooking up another speaker to the speaker output. For example, if you are not getting sound from the left channel speaker, connect the right channel speaker to the left output. If you still get no sound from that side, the problem is in your amp or source electronics. Should you isolate the problem to the speaker, contact the authorized Polk Audio dealer where you bought your speakers. Authorized Polk Audio dealers are the best source for advice and assistance.
