Two 4-ohm single voice coil subs

Advantages
When you're looking for big bass, having two subs makes a lot of sense. After all, sound is just the movement of air, and with two subs you can move lots of air! As before, price can be an advantage when selecting 4-ohm single voice coil subs. Sure, two subs will take up more room, but what do you want — trunk space or bass?

The right type of amp to use
This setup is perfect for a mono sub amp. By wiring the two subs in parallel (see the diagram) you'll show a 2-ohm impedance to the amp. Mono amps are built for just this kind of situation, so you'll get maximum power output from your amp investment. Check the diagram below for how to hook it up.
