You need a 5 or 6 channel amp and an active crossover to split the signal between subs and main speakers.
Secondly, can an amp power 4 speakers and sub?
If you’re wanting to install a 4 channel amp for 4 speakers and a subwoofer but only have 2 stereo channels available, that’s ok. As shown in my diagram, you can connect 2 channels to a 4 channel amp using either the speaker level inputs wired in parallel or by using RCA “Y” adapter cables.
One may also ask, can I run 2 subs off a 1 channel amp? you can also get another one of those amps and run one sub per amp at 2 ohms, be pushing 400w rms to each sub, which is what it can handle. You CAN run 2 speakers off of a 1 channel amp, just that amp is way too little power for your subs.
In this manner, can you bridge 4 channels 1?
It is not possible. 4 will become 2, and 2 channel can become 1.
Can you use a 4 channel amp for 2 subs?
4 channel amps were not designed to power subs. Mono block amps are sub amps. You get more power and more efficiency- for subs that is. Now powering multiple component speakers, 4 channel is the way to go.
How do you hook up 4 speakers to a 1 channel amp?
The easiest and a safe way to connect 4 pairs of HiFi speakers is to use a 4 zone speaker selector switch. This is relatively simple to wire, just run a wire from the central location (lounge room) to each speaker. The box should also look after any impedance matching to prevent amplifier overload.
Should I have a separate amp for speakers and sub?
Well this depends on a lot. If your using 50 rms or less speakers then you might be perfectly happy just running them off the head unit and a mono amp of the sub stage. If you want more powerful speakers then running a separate amp for them would be ideal if it’s in your budget.
What amp do I need for 4 speakers and subs?
A four-channel amp works to power: Four speakers; Two speakers and a subwoofer—you can use a four-channel amp to power a subwoofer and two rear full-range speakers by bridging two of the channels to power the sub.
What does a 4 channel amp mean?
A 4 channel amplifier is a stereo amplifier with 2 more channels built in to boost (amplify) weak input signals to a higher voltage signal. This drives speaker voice coils to move the speaker cone and produce sound.
What hits harder 2ohm or 4ohm?
In terms of which subwoofer hits harder, drawing from the explanation as given above, the 2-ohm subwoofer produces a louder sound than the 4-ohm subwoofer. So in that sense, technically speaking, the 2-ohm subwoofer hits harder than a 4-ohm subwoofer.
What if my amp is too powerful for my sub?
You have to ensure that the specs of your devices are in line. Otherwise, too much power could cause damage to both your external amp and active subwoofer. So, using an external amp with your active sub just to push the output to extreme levels is not ideal.
What is bridging an amp?
Primarily a live sound term, “bridging” is a means to configure a 2-channel amplifier to drive a single loudspeaker with more power than the two original channels. For example, a 100-watts-per-channel amp may output a single channel of 300 watts after bridging.
