manual abstract
A basic single amplifier system is shown in figure 1. DECK Figure 1. Basic Single-Amplifier System Using Existing Speakers (1) Adding Equalization. To improve the system even more, you could add an equalizer, such as an ORION 300 PRQ Pre Amp Equalizer, 600 EQM Equalizer, or 500 PMQ Parametric Equalizer (see page 6). The equalizer would be inserted in the system between the deck and the amplifier as shown in figure 2.

Basic Single-Amplifier System Using an Equalizer and Existing Speakers (2) Front and Rear Speakers. If your car is equipped with front and rear speakers, you will want to use a separate amplifier for each pair of speakers as shown in figure 3. A single 4-channel 425 HCCA could also be used for this system (see figure 16). DECK Figure 3. Basic Two-Amplifier System Using Equalizer and Existing Front and Rear Speakers (3) Adding Subwoofers. For added punch, you could add a couple of subwoofers to the system as shown in figure 4. This will give you the most coherent and natural sound. In this system, a pair of midrange/tweeter speakers are located In the front (usually In the top of the dash), and a midrange/ tweeter speaker is located in each rear door or side panel. The subwoofers are installed in the rear. This does not mean that the passengers seated in the rear will be overcome by the bass. Low frequency sound waves tend to wrap around the interior such that they are perceived as coming from all directions. IMPORTANT NOTE: At this point, you must determine if your car has enough power to supply the needs of the engine, lighting system, and air conditioning system as well as the audio system. An existing car electrical system can generally handle up to four 225 HCCA or up to three 250 HCCA amplifiers. If you plan to use more, or larger amplifiers, refer to the discussion on "power requirements" on page 29. (4) Adding Crossover or Bridging Modules. An existing speaker system can also include a crossover module and/or bridging module similar to the custom systems described in paragraphs B through F below. B. USE OF A CROSSOVER MODULE An ORION 200 CRX Active Crossover or 300 CRX 3-Way Active Crossover can be one of the most important additions to your car audio system. It lets you adjust the highs and midranges to where they sound best, then independently adjust the lows to where they sound great. The 200 CRX Active Crossover contains a low pass filter section (for your subwoofers) and a high pass filter section (for midranges and tweeters). The 300 CRX 3-Way Active Crossover contains a low pass filter section for the sub- DECK ORION 600 EQM EQUALIZER or 500 PMQ PARAMETRIC EQUALIZER DIN Cable NOTE: The DIN and RCA input connectors for all amplifiers are wired in parallel. This means that when an input is connected to the DIN connector, it is also present at the RCA connectors and the other way around. This makes it possible to connect several amplifiers in parallel as shown in this figure. o MID/HIGHS AMPLIFIER Right Yel I ow (+) Black/Yellow (-) ORION 225 H "Phantom power is supplied to the equalizer by the amplifier through the DIN cable.

Typical Way of Adding Subwoofers to a System 9 woofers, a bandpass filter section for the midranges, and a high pass filter section for the tweeters. (1) Use of 200 CRX Active Crossover. This crossover module can be used in a variety of ways: It could be added to the simple two-amplifier system as shown in figure 5. It could also be used in a 3-amp system as shown in figure 6. Note in figure 6 that an ORION 200 DAB Dual Amp Balancer has been added to control the level of sound that comes from each section of the car audio system. (2) Use of 300 CRX 3-Way Active Crossover. For even better control, use the 300 CRX as shown in figure 7. This will give you separate control of the low frequencies, midrange frequencies, and high frequencies. C. USE OF A BRIDGING MODULE The ORION 400 BDG Bridging Module can turn your amplifiers into real power houses. Bridging an amplifier converts a two-channel amplifier into a single channel amplifier (mono, output). Each internal channel “sees” half of the total impedance of the load. For example, when using 4-ohm speakers, each channel in the amplifier sees half of this 4 ohms or 2 ohms. If you were using a 225 HCCA amplifier, which delivers 25 watts per channel, the output delivered to each speaker will be 100 watts when bridged, thus a 4 times increase in output. The 400 BDG ...
