Without a doubt about just how to hookup 2 amps

Multi-Channel Amplifiers Multi-channel amplifiers are fundamentally the identical to a stereo amplifier aside from the undeniable fact that they’ve a lot more than 2 stations. Now this might seem fairly apparent for some individuals however you must understand that this website is perfect for individuals who are not used to automobile audio. This area will (ideally) clear up any misconceptions or confusion about multi-channel amplifiers generally speaking.

Generic 4 channel amplifier:


  1. As you care able to see regarding the 4 channel amplifier below, you will find 4 input jacks and 4 sets (+&- terminals) of corresponding speaker output terminals.
  2. Addititionally there is an input selector that allows one to only use 2 inputs to push all 4 stations and never have to make use of all 4 input jacks. As soon as the switch is within the 2 channel input place, just 2 inputs (1 right and 1 left) have to drive every one of the stations. Once the switch is within the 4 channel place, all 4 networks need certainly to be driven seperately and they are independent of each and every other.
  3. You may note that you can find 2 crossover selector switches. They enable either set of networks (front or back) to try out either a complete range sign (that will pass the complete input signal to your amplifier part), a top pass signal (obstructs out of the low frequencies) or the lowest pass signal which blocks out the high frequencies but enables the bass to try out through. Now these are the best of integrated crossovers. They don’t really permit you to choose the crossover point or slope. Some amplifiers permit you adjustment that is full of parameters but also for this instance, I decided to just show this sort (read: I happened to be too sluggish to draw such a thing fancier). The front 2 channels are set to high pass on this amplifier. A corner networks are set to low pass and the input selector switch is placed to 4 channel meaning that all 4 networks should be driven independently (all 4 input jacks should be utilized).

Fundamental System: In this diagram, you can view this 1 pair of pre out jacks through the mind device are linked to the leading inputs of this amplifier. To permit all 4 stations become driven, the input selector is defined to 2 channel. The leading channel crossover is defined to pass that is high. The front channels are utilized to operate a vehicle a set of coaxials. A corner channel crossover is placed to pass that is low the trunk networks are now being utilized to operate a vehicle a set of subs. The relative output levels would have to be set with the gain controls on the amplifier in this type of system.

4 Channel Input: In this diagram, all 4 input networks of this amplifier are now being driven separately. The input selector is placed to 4 channel. Anything else is equivalent to the diagram that is previous. This setup could be just a little much better than the past diagram because you can adjust the general degrees of the coaxial speakers therefore the subs by using the fader control in the head product.

Bridged Rear Channels: This diagram shows the rear stations bridged. Whenever bridging an amplifier , you need to ensure that the impedance that is total of speakers just isn’t too LOW for the amplifier you are utilizing. If you should be confused in regards to the impedance of numerous presenter lots, try reading either this website website link or this website website link.

Both Front and back Channels Bridged: This diagram shows the method that you might utilize the amplifier with both the front side and channels that are rear. You can view that the trunk preamp production stations associated with mind device are linked to the 4 channel amplifier while the input selector is scheduled to 2 channel AND BOTH crossovers are set to low pass. The pre that is front of this mind device are linked to split amplifier which will be used to operate a vehicle the front/high regularity speakers. The output that is relative for the high and low regularity speakers would once again be adjustable through the fader control of the pinnacle device.

4 Channel amp on front side speakers 2 channel amp on subs: This diagram shows the way you can use the 4 channel amplifier from the high regularity speakers and a second amplifier in the subs. Note the crossover settings for each regarding the amplifiers.
