Can you run two subs off a mono amp?

Are 12 or 15 inch subs better?

The answer to the question of whether 15 inch subwoofers have better base than 12 inch subs is not an easy one to answer. The fact is, “better” is a personal opinion. 15 inch subwoofers are larger and displace more air than 12 inch subwoofers do, so the 12 in will have a crisper, sharper sound than the larger ones.

Is it better to run subs in series or parallel?

While series wiring of multiple subs increases the total effective impedance, parallel wiring of multiple loads lowers the total effective impedance. With subwoofers rated at equal impedances, the system impedance is equal to the impedance of one sub voice coil divided by the number of subs.

What amp do I need for 2 1000 watt subs?

We are doubling the power each time. So, if indeed your speakers are rated at 1000 watts rms @ 4 ohms per cabinet, a good rule of thumb is to get a power amp with “ headroom” above the rated power. In this case an amplifier rated at 2000 watts per channel @ 4 ohms would give you 3 dB of headroom.

How big of an amp do I need for my subs?

Find the Sub’s RMS Rating For multiple subs, multiply the number of subs by their RMS ratings for a total RMS rating. The amp you choose will have to be capable of powering 75% to 150% of the total RMS rating for the entire subwoofer system.

Are 2 subs louder than 1?

The 2 subs will probably be just a bit louder (you would need a meter to tell) because the single sub would be entering into power compression and becoming less efficient as you increase the power.
