Use common sense and practice safe listening habits when listening to or adjusting your audio system. Do not use factory ground locations, seat bolts, or brackets that are spot welded. The gauge of power wire used should take into account the total current draw of the system, and the length of wire used.http://www.net-work.cz/data/bt-norstar-manual.xml IASCA and other auto sound competition organizations have charts available for this; you can also find a chart in the MECP study guide. Minimum wire gauge recommendations for the individual amplifiers are listed on the specification page. Always use the same gauge wire for the amplifier ground that you use for the power wire. Be sure to examine the battery ground cable of the vehicle, and if necessary, upgrade it by adding an additional ground wire that is the same gauge as the amplifier’s power wire. Remember, the amplifier can only deliver its rated output when it is not current limited by the power and ground supply wires. Keep in mind that heat is the longterm enemy of automotive elec- For low impedance speaker applications or restricted ventilation installations, an external cooling fan may be advisable. Proper grounding of the signal source is mandatory for the amplifier to reach its performance peak. If the RCA inputs are not grounded adequately via the signal source, electrical noise from the vehicle may be picked up in the system. Even though the connectors fit properly, the control knob and connector pin positions may be different and the amplifier will be damaged. And the protect light is on as well just one by one remove the fuses and then wait one minute not doing anything and just re install the fuses one by one and when the blue directed light reactivates (THE BLUE LIGHT ON TOP OF THE AMP COVER) you are good to go. Sometimes just removeing the amp trigger wire and reinstalling it will do the same thing.Just wish i new what caused it to do it in the first place, this is just my solution to get it working again.The formula that shows the proportions of Voltage (Electricity) and Amperage (Intensity) to Watts (Power). That means you amp is now pulling 140 amps of current to make up for the voltage drop, Your wire that is going to the amp is probably getting pretty warm at that time also unless you have 4 ga or larger.https://ayurvedia.ch/3m-x30-manual So when the voltage gets too low the amp will turn off and go into protect mode to keep the current in the rails from getting the amp so hot it will eventually cook the components inside of it. You will be looking for a higher output alternator just like everyone else who has high powered amps.Try chassis worked for meIf the amplifier is working normally you can ignore the light. Note that this is NOT the protection LED for the amplifier.Everything still applies.It is stable at 1ohm and will produce 1,200 watts into that load. So you want your subs wired as close to 1 ohm as possible. The only 3500 watt Pioneer Premier series subs I could find were the models number TS-W3002D2 and TS-W3002D4 with dual 2ohm and dual 4ohm voice coils respectively. The wiring options for the D2's result in 0.5ohm (too low), 2 ohms, and 8ohms. Your best option would be the 2ohm configuration which would be voice coils in series and subs in parallel. Options for the D4's result in a 1ohm load and a 4ohm load. Your best option would be the 1ohm configuration which would be voice coils and subs parallel. It'll bring up all of the possible wiring configurations along with the final impedance load. Hope this helps.Answer questions, earn points and help others. Which would you get. I can get both for the same price, but the Directed has to come across the border. Even the Directed is going to need quite a bit of juice. I'm going with Jim on this one. Get the Orion and run it at 2 ohms. Less risk of failure and less strain on the electrical system Even the Directed is going to need quite a bit of juice. Get the Orion and run it at 2 ohms. Less risk of failure and less strain on the electrical system I could I guess haha.Waitin on a email from my box guy. The directed is not even comparable Just like the amps it shares boards with.

You can run them all at 1 ohm with a bit of cooling help. It's easy! Sign in here. I do believe they make Orion amps, among others. Looks like a decent buy. Reading those specs brings up a question for me. That amp has three 30A fuses which should be equal to one 90A fuse. This seems a little odd to me. I would think it should have at least a 120A fuse. It makes me wonder if that amp can actually put out 1200w continuously if it is only drawing 90 amps.It came with a 150A ANL fuse.Anyone have an answer to that? Fuses are made to blow at a rate of speed that increases proportionally to the percentage of overcurrent passing through them.Computers (2,549) Laptops, Car Audio (255) Head Units.

Battery and ground connections to the vehicle should be made with crimped ring terminals of the appropriate size (surface area is what counts); soldering the terminals after crimping is also recommended. Proper grounding of the signal source is mandatory for the amplifier to reach its performance peak. If the RCA inputs are not grounded adequately via the signal source, electrical noise from the vehicle may be picked up in the system. Gain Control - Controls the amplifier's sensitivity and is used to match the input level of the amplifier to the output level of the signal source. Subsonic Switch - The subsonic filter attenuates frequencies below 30Hz by 24dB per octave. Bass EQ Switch - Adds 8dB of bass boost to the subwoofer when selected. (Refer to Parallel Synced Gain section of this guide for amplifier and speaker connection diagrams. ). This allows the master amplifier to control gain, filter, and sub-level on both amplifiers. This combination allows the amplifiers to drive common subwoofer loads while being synced together via an out-of-phase audio pre-amp signal from the master amplifier. Make sure that each amplifier sees the same speaker impedance. WARNING: The amplifier's gain control is bypassed completely in SLAVE mode. Do NOT connect any signal source to the amplifier in SLAVE mode that exceeds 200mV. Because this amplifier is only designed for subwoofer applications, the low-pass crossover is active at all times. The crossover point is adjustable to allow more precise system operation.

When playing your system at high levels, please use hearing protection and avoid long term exposure Directed Electronics all rights reserved 4 LIMITED TWO-YEAR CONSUMER WARRANTY The warranty is printed on the rear cover of this manual. This warranty does not cover labor costs for the removal and reinstallation of the unit. It is important for you to record and retain the following data. Activates to protect the amplifier when the temperature is too high, the output has a DC offset, a short was detected on the output, or the amplifier power cables have been improperly connected (reverse power). Low-Pass Frequency Control (front) - adjusts the frequency (50Hz 500Hz) of the low-pass crossover. High-Pass Frequency Control (front) - adjusts the frequency (50Hz 500Hz) of the high-pass crossover. 4. HI Input (high level input) - Accepts 1v to 10v input from the headunit s speaker output. The amplifier will automatically wake-up when the input is greater than 1V. 5. Level Control (rear) - continuously adjusts from 250mV to 5V for full power output. Low-Pass Frequency Control (rear) - adjusts the frequency (50Hz 500Hz) of the low-pass crossover. High-Pass Frequency Control (rear) - adjusts the frequency (50Hz 500Hz) of the high-pass crossover. 6. RCA Inputs (rear) - accepts RCA input from a source unit, preamplifier, or equalizer. 7. PRT (LED red) - illuminates when the PRT (Protection) function is active. The input sensitivity can be adjusted from approximately 200mV to 5V. Refer to Testing the System and Adjusting the Sound of the System sections of this guide for detailed instructions on setting the gain. Internal Crossover Configurations The crossover section of these amplifiers is continuously variable and extremely flexible. This circuit is designed to optimize the performance of WCC subwoofers in all types of enclosures. When using WCC loudspeakers, minor deviations from the recommended frequency ranges can provide superior results depending on your speaker locations and your vehicle acoustics. Setting crossover frequencies higher than recommended will not cause damage and may provide superior sonic results depending on your system's performance goals. Refer to your loudspeaker owner's manual for assistance in choosing the proper crossover frequencies for your system. WARNING! DO NOT set crossover frequencies lower than the speakers recommended operating range. This can cause driver failure that is not covered by the manufacturer's warranty. Low-Pass Crossover When the switch is to the middle (OFF position), the low-pass crossover is bypassed. When the switch is in the left (LPF position), the low-pass crossover is active with a 2nd order (12dB per octave) slope. The low-pass crossover is continuously variable from 50Hz to 300Hz. High-Pass Crossover NOTE: Not applicable to the 5001 and 8001 models. When the switch is to the middle (OFF position), the high-pass crossover is bypassed. When the switch is to the right (HPF position), the high-pass crossover is active with a 2nd order (12dB per octave) slope. The high-pass crossover is continuously variable from 50Hz to 500Hz. Additionally, boost can be added at the high-pass crossover frequency for improved bass output while still protecting the woofer from excessive excursion. WARNING! Maximum boost can potentially cause woofer damage due to over-excursion. Fine Tuning the Crossovers The low-pass and high-pass crossover sections are each marked at four frequency points for ease of system adjustment. The low-pass crossover section is marked at 50Hz, 100Hz, 300Hz, 400Hz, and 500Hz. The high-pass crossover section is marked at 20Hz, 33Hz, 90Hz and 150Hz.
