The system sound level will of course be very low, and the following procedures will help you to match the amplifier input sensitivities properly to the head unit output signal level. It is important to match the amplifier LEVEL input sensitivity to the Radio/CD output sensitivity. This can be located in the Radio/CD manual. If the Radio/CD output sensitivity is 2 volts, then adjust the amplifier LEVEL input to 2 volts. If you are not sure what the Radio output sensitivity is, follow these gener

- HI PASS: 100 Hz - LOW PASS: N/A Interconnect cable checklist: - Using good quality RCA cables, feed the front and rear outputs of a head unit to 1 channel bass amplifier: the inputs of the 4 channel amplifier as shown. - Subsonic filter: 10 Hz to 40 Hz - Also connect the LINE OUT of the 4 channel amplifier to the LINE INPUT of the - LOW PASS: 80 Hz 1 channel amplifier as shown. Please note that these frequency points are suggestions only. Refer to the Mono bass woofer wiring: loudspeaker manuf

LINE OUTPUT: The line output passes through signal from the line inputs which allows you to daisy chain multiple amplifiers from one signal. The Phase Shift is fully adjustable from 0 to 180 degrees and this allows you to control time alignment. Accepts line level balanced input from 0.4v to 18v. -The LINE INPUT signal is routed directly to the LINE OUT RCA jacks, and not affected by the settings on the amplifier simplifying daisy chaining of amplifiers. The BRE2500.1D is a linkable amplifier an

A “Y” adapter - 1 ohm. may be needed as shown in the diagram. - Use at least 16 gauge speaker wiring. These amplifiers have dual speaker terminals, simplifying the hookup of multiple speakers. The 2 positives are the same and the 2 negatives are the same. Crossover frequency control checklist: - LOW PASS: 35Hz to 250Hz - SUBSONIC:15 Hz to 35 Hz - BASS EQ: 0 to 10dB - PHASE: 0 to 180 degrees Level control checklist: - Refer to the section “Setting up systems after installation for best performanc

All of the amplifiers have variable crossovers built in, with added touches such as subsonic filter, bass equalization and an HFR-3 remote control module for the monoblocks that allows overall Level control from reach of the drivers seat. To insure years of listening pleasure, all amplifiers have a built in diagnostic mode that will detect shorted speaker leads, low impedance, dangerous high temperatures, DC shorts and will shut down the amp to help prevent damage. General Installation Procedure

This state of affairs will be indicated by the front panel PROTECT LED lighting up under the following conditions: 1 - A sort circuit on the loudspeaker leads. 2 - An internal amplifier fault that causes a DC offset on the loudspeaker output. Should the amplifier go into diagnostic mode, simply disconnect all RCA and speaker leads, while keeping +12 volt, power ground and remote leads connected. 1. Now turn the amplifier back on, and if the diagnostic LED lights, the amplifier has an internal fa

The next step is to scrape the paint off the vehicle chassis , slightly larger than the ground lug, at the connection point. Drill a clearance hole in the chassis, the same size as the lug hole, and use a bolt, spring washer and nut to securely fasten the ground lug. Use petroleum jelly to coat the bolt/lug connection, to prevent oxidization with time. TIP: Use the same approach when installing head units, equalizers or any audio equipment for that matter - run short individual grounds from each

1 set for channels 1 & 2 and 1 set for channels 3 & 4. In addition, the 4 channel models have a Mode switch which allows you to select 2, 3 or 4 channel operation. Switch to 2 channel if you only have 1 set of RCA’s in CH 1/2 and the unit will automatically supply signal to channels 3/4. Select 3 channel when you only have RCA’s in CH 1/2 but plan to run channels 3/4 bridged. Select 4 channel if you are providing RCA’s to channels 1/2 and 3/4. The X-OVER slide switch selects the internal crossov
