Choosing one can be pretty tricky.

So it’s best to ask yourself, “What kind of shallow mount subs do I want?”

Consider the level and the type of music you’ll play. Then think about the confinements of the subwoofer’s location in your car. 

Once you have the answers, then it’s the right time to get one.
