[. . . ] Although lengthy, this chart cannot address every single problem possible but mainly the ones most common. PARAMETER/FEATURE Channels Size ( W x H x D) Weight Crimping style speaker terminals?Maximum terminal wire size Subsonic filter Separate front/rear or left/right gains?Speaker short, short to +12V, and short to ground protection? [. . . ] The speaker wire chart shows the minimum recommended wire size for a single audio output channel driving a loudspeaker at a given distance with a maximum power loss of 0. 5 dB, the threshold of audibility. (Wire sizes larger than those noted are usually a waste of time and money since they offer little or no performance improvements. ) LOUDSPEAKER WIRE CHART WIRE LENGTH 5 ft. The input line to the "trigger" connection must be properly connected to the radio's trigger line which is often also the power antenna line. If the amp is properly wired, but the light does not turn on, verify the trigger line is properly connected, is receiving +12 volts, and the speaker outputs are not shorted to themselves or ground in any way. MIN MAX LEFT (+) LEFT (­) GREEN GREEN-BLACK (NOT USED) GREY-BLACK 3. ) INPUT GAIN CONTROL - This controls the gain setting on the input of the amplifier. For high gain settings ( 0. 3 volts), this says that it takes ONLY 0. 3 volts to drive the amp to full output. For low gain settings (near 4 volts), this says that it takes nearly 4 volts to drive the amp to full output. If the amp is often going into distortion at only moderate volume settings on the radio, rotate this control towards the 4 volts setting to reduce the distortion. RIGHT (­) RIGHT (+) GREY "Common Ground" Radio Outputs 4. ) HIGH LEVEL INPUTS - Should RCA cables not be available from the radio you are able to tap onto the audio signal from the high level speaker outputs of the radio. This is most commonly used when the amp is an add-on device such as for a subwoofer system. GAIN HIGH-LE +- VEL ­ IN -+ PUT R L MIN MAX 5. ) LOW LEVEL INPUTS - The more commonly used inputs, these are connected to the standard RCA outputs available on nearly all aftermarket radios today. These lines are dedicated to left and right outputs of the radio, be it for front or rear speaker installations. The input gain settings of the amplifier (0. 3 - 4 volts) are referenced to these inputs.

It should be fastened to a clean ground connection in the car, capable of handling high current loads and within 3 feet (absolutely no longer than 3 feet). Such a system will not perform as well as an "active" system because the slow attenuation (roll-off) of the frequency response resulting in a moderate amount of over-lapping of the sound spectrum between the satellites and subwoofers. It is important to remember that although surprisingly pleasant performance is achieved, this is a compromise system and will NOT perform as well as a dedicated 3 channel system with electronic crossovers. ­9 ­ SYSTEM CONFIGURATION #3 Full-Range Full-Range + L Speakers ­ +R ­ Crossover Position + Bridged ­ X-OVER 100 flat 75 Subwoofer Full-Range Full-Range 2 Channel Dual Subwoofer Mode The largest improvement in sound quality always comes when adding some kind of subwoofer via a dedicated subwoofer amplifier and electronics crossover. The electronic crossover ensures minimal overlap of the bass response with the mid and high frequencies from the other speakers resulting in a more accurate performance compared to conventional coaxials with additional power. By installing this amplifier in the stereo mode, you are able to drive two subwoofer speakers and in to low impedance loads (e. g. , 2 ohms) without over heating the amplifiers. Also, such an installation more easily supports a standard 2 speaker woofer box that may already be constructed. Since two woofers can play 6 decibels louder than one at a given power (due to acoustical laws of "mutual-coupling"), the resulting sound pressure level is substantial. This is probably the most common use for a conventional two channel amplifier there is. SYSTEM CONFIGURATION #4 Full-Range Full-Range For higher output, you can connect a subwoofer to two output channels. Look for the + and ­ to indicate the correct connections. + L Speakers ­ +R ­ Subwoofer Full-Range Full-Range + Bridged ­ Crossover Position X-OVER 1 Channel Bridged Subwoofer Mode By electrically connecting a subwoofer speaker in the way shown above, you are able to greatly increase the output power delivered from the amplifier to the speaker. Such a circuit increases the voltage "swing" across the speaker which increase the power seen by a factor of 2 to 4 times that in stereo mode. This is a very logical set-up for systems that are space limited to allow for only one subwoofer in a vehicle. The number and box volumes are compensated by simply more amplifier power pushing a single speaker. 4W (min) 100 flat 75 Such a configuration is also a surprisingly good performer.
