It removes sound that is so low the speaker cannot reproduce it. You see the cone moving but hear no sound.This can be very hard on your woofer especially at high power. If you are using a ported subwoofer subsonic enclosure at high power you should freqhz use a Subsonic Filter to limit cone movement at very low frequencies. Speaker outputs This amplifier is a mono design. Meaning it has only 1 channel. It is equipped with a single large block terminal for speaker connection. Make this connection carefully and neatly. If the wires ever come in contact with each other the amp will go into protection. Know your total ohm load before you make any connections. Note the ohm load switch. Use the 2 ohm position for any load over 2 ohms. For any load under 2 ohms switch to the 1 ohm mode. 5 Bridging Bridging is a way to combine the power of 2 channels into 1. When you wire the amp bridged you have a higher voltage differential between + and -.That means MORE POWER. If you have 2 identical, properly designed mono amplifiers (They can not be a stereo amp that is bridged internally) you can bridge them together to create 1 channel. 1. Run a jumper wire between the negative (-) speaker output of the 2 amps. Use the same gauge speaker wire you used to connect the speaker. Run a speaker wire from amplifier 1 (Normal) positive (+) output to the woofer +. (H s c 3. Run a speaker wire from amplifier 2 (Slave) positive (+) output to the woofer ■ When you are finished it should look like this. o 4 OHMS 1 G - Warning When bridging any amp or amps, each channel sees half the ohm load. 4 ohms bridged is the same as 2 ohms stereo. I ohm bridged is equal to 1/2 ohm stereo. Check the compatibility of you woofers and amplifier before you begin. G Bridging Cont. For bridging to work both amplifiers must be playing exactly the same signal at exactly the same output level.To make this easier we have added a "Slave ln"and "Slave Out"to this amp. When you use the Slave In all the gain and crossovers are bypassed.This eliminates all the compli-cateted tuning needed to match each amp. When bridging 2 amp, 1 amp will act as the positive output and the other will act as the negative output. The negative amp will need to play "out of phase"from the postive amp. Imagine it like this. The positive amp is pushing the woofer and the negative amp is pulling. You can do this by changing the "Phase" switch to "OUT" Please see the switch setting below. Amp 1 (NORMAL) Set the load switch to the correct location for your 4 ohm bridged set to TWO 2 ohm bridged set to ONE woofers. Set the phase to "IN; Run a mono RCA cable to "SLAVE OUT" Amp 2 (SLAVE) Set the load switch to the correct location for your woofers. 4 ohm bridged set to TWO 2 ohm bridged set to ONE Set the phase to "OUT' Run a mono RCA cable to "SLAVE IN" 7 Installation Instructions 1. Disconnect the negative cable from the car battery. Tape up the end so it is isolated form the battery. 2. Run the power wire (4 AWG min.) from the battery to the amplifier. Plan this part of the installation carefully. This cable will carry very high current. If it should short to the body and it is not properly fused it could catch fire. 3. Connect the power wire to the battery using a fuse capable of the total current load of all amplifiers connected. Don't install the fuse yet. Wait until the end. Locate the fuse as close as possible to the battery. If the fuse is further that 18 inches (wire length) from the battery you should reevaluate the wire and fuse placement. 4. Find the closest clear metal area to the amp for a ground. Sand, grind or scrape all paint and undercoating from the body and screw the ground securely to the body. It is advisable to test the ground with an ohmmeter between the ground cable and the negative battery cable to insure a good low resistance connection. Some alloys used in modem cars do not offer the best ground. If you believe this is the case consult with the vehicle manufacturer. 5. Run the speaker wire to the speakers. It is advised that you leave some extra wire at this point. You can "clean it up"later. 6. If you haven't already done so, mount the amp now. 7. Connect the power and ground to the amplifier. Only after this step should you install the fuse at the battery. 8. Connect the remote wire from the head unit to the amplifier. Now is a good time to turn on the amp for the first time. Make sure it turns on properly and does not go into protect. B 9. Connect the speaker wire to the amp and speakers (make sure the amp is off first). Make sure the polarity (+ and-) is correct. 10. Connect the RCA's to the amp. 11. Double check the amplifier controls at this time. Make sure everything is set correctly for your system. 12. Now you're ready to play it for the first time. It is best to leave the gain all the way down at first. Start with the head unit volume low and work your way up. 13. Now you can tune the ...
