Electrical interference The inside of an automobile is a very hostile electrical environment. The multitude of electrical systems, such as the ignition system, alternator, fuel pumps, air conditioners, to mention just a few, create radiated electrical fields, as well as noise on the +12 volt supply and ground. Remember to isolate the problem - first unplug amplifier input RCA cables, if the noise is still present, check the speaker leads, if not, plug the RCA’s back, and investigate the source d

SAMSON HIGH PERFORMANCE AMPLIFIERS The Samson Series products have been designed to a very high level of performance, with features unavailable in any other product. All of the amplifiers have variable crossovers built in, with added touches such as subsonic filter, bass equalization and a remote Level control module(some models) that allows subwoofer Level control from the drivers seat. To ensure years of listening pleasure, all amplifiers have a built in diagnostic mode that will detect shorte

- 1/2CH X-OVER: FULL - 3/4CH X-OVER: LPF The following example shows how to create a 3 channel system by mono bridging channel pair 3 / 4. In order to create a 2 channel system, simply follow Crossover frequency control checklist: the example to also mono bridge channel pair 1 / 2. Channels 1/2: - HI PASS: N/A Interconnect cable checklist: - LOW PASS: N/A - Connect the inputs of channel pair 1/2 to a suitable stereo source, e.g. a head unit with good quality RCA cables. Channels 3/4: - A MONO si

Finally, connect the main +12 volt cable to the battery, with the main fuse removed, and we are almost ready to power up the system. Power up the system: The following procedure may seem like overkill, but there is nothing more frustrating when turning on a system for the first time, and it does not work properly immediately. First, make sure the head unit is off, and turn all level controls to minimum (counterclockwise), including the head unit volume control. Set all equalizers to 0 dB (no boo

1 - Check all connections, especially for good grounds. 2 - Make sure that no speaker leads are shorting to exposed metal on the vehicle chassis. 3 -RCA cables are notorious for their problematic nature, so check that these are good, in particular the shield connections. We have also provided several videos that will help you with your battery, alternator and even Big 3 upgrades at . 10 As the manufacturer of Maxxsonics, MB Quart, Autotek, Crunch and Hifonics car audio products, Maxxsonics USA I

Next you should insert a CD or cassette that you are familiar with to use as a reference, and turn the head unit volume control to about 80% of its full setting. 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 Radi

Here we show how to use the 4 channel

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
