Can a 4 channel amp run 8 speakers?
Most external amplifiers can power more than one speaker per channel. For example, a 4 channel amplifier may be able to power up to 8 speakers. Don’t try to wire more than two speakers to each channel or you could damage your amp and your speakers. A subwoofer would be wired in a completely different way.
How many speakers can a 8 channel amp power?
This gives you four speakers per channel (rated at 8 ohms each).
Can a 4 channel amp power a sub and 4 speakers?
4 Channels 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.
Can you run a sub off a 4 channel amp?
To drive 4 speakers and a sub with a single 4-channel amp you’ll have to make a few compromises. You’ll likely have to give up front-rear fader control ability as you’re giving up 2 channels for the rear speakers to drive a sub (2 front/2 rear). Most but not all car amps today can handle speaker loads down to 2 ohms.
How to wire a 4 channel amp to 4 speakers?
System 2: 2 speakers in parallel to each front channel = 2 Ohms x 2 + 1 subwoofer wired for 4 or 2 Ohms on the rear channels bridged for more power. 4 channel amps that handle 2 ohms bridged are less common but they are out there.
Can you have 4 speakers and a subwoofer?
You may need a few extra parts. Driving 4 speakers from 2 channels means the speakers are sharing the amp’s power, so you’ll have less power available to each of those. That being said, don’t worry too much! You can still enjoy the music you love with a nice-sounding 4 speaker + subwoofer system.
How big of an amp do I need for 4 speakers?
You can definitely use a single 4 channel amp that’s 2Ω capable to run all 4 pairs of speakers if you like. You’ll want the amp to have decent power, however, because when speakers share an amp channel in parallel, they split the power. (Example: two 4Ω speakers on a 50W/channel amp will now be able to get only get up to 25W each).
How many watts does an 8 ” subwoofer need?
You have two Alpine Type R SWR-8D4 8″ subwoofers and you want the right amp for them. They are DVC 4-ohm subs rated at 350 watts RMS each. Two 350 watts RMS subs together need a total of 700 watts RMS. Using the chart in Step 2, 2 DVC 4-ohm subs can be wired together to form a 1-ohm, a 4-ohm, or a 16-ohm load.

Do you need an amplifier for a subwoofer?
It’s not possible to sufficiently power a subwoofer with a built-in amplifier, so if you want to install a sub you are going to need an external amplifier anyway, but in addition to that, if you want to add more than the standard 4 speakers that most head units will allow, you are going to need to shell out the extra money for an external amp.
