What size amplifier should you get for a 2 10-inch subwoofer?

Let’s say you have two 10″ sub woofers that can take 300 watts RMS each and want to put a 600 watt amplifier on them. Is this too much power for those subs?

That will not be enough power to properly drive those subs to their full potential. That would only give you 200 watts for each sub, which is lower than what they should receive.

In order to achieve maximum performance out of your subs, you should look for an amplifier that will output at least 1200 watts RMS per subwoofer . To make a mathematically easy example, let’s say that once again we have 2 10’s with a max rating of 300w RMS x2 = 600w . In order to get the most out of these subs we would want to get an amp that gives us at least 1200watts RMS . That would be a good match for your subs, and any more power than 1200 watts RMS per sub is considered by most people to be excessive.

In short, you will need an amplifier with a minimum of [at least] 4 times the RMS of your subs.

Can you run 2 subs on a 1 channel amp?

Yes you can! You will need to split your signal into the 1 channel amp. A simple way to do this is by using an RCA Y-Adapter. This adapter has two male endpoints and splits the input into two signals that can be used on most amps with one or more channels for powering subs. Of course, there are better ways of doing this such as using an amplifier that has 2 or more channels, but for simplicity sake this will work just fine.

2 on 1 channel?

Yes, you can run 2 subs with 1 channel.

You will need to split the signal though. A Y-Adapter is convenient for this.

Will a 750 watt amp push 2 10 inch subs?

That is not enough power to properly drive those subs to their full potential. Those subs would like to see at least 1200 watts RMS and 750 watts RMS is only 50% of that!

You will need at least 1200-1500watts RMS.

If you were looking to run 2 10″ subs which need 300 watts RMS each then you would want an amp that at least has an RMS of 1200 watts.

Yes, but not enough power for those subs and they will likely receive damage due to the lack of power.

10″ subs can sound similar to 12″ subs if the enclosure is ported correctly, but in general; yes, 12 subs will be superior to 10.

It really depends on preference and application. They both have their uses depending on what you need them for. Yes, they are usually louder, but one is not better than the other.

Is a 10 inch subwoofer enough?
