Subwoofer Amps Buyer’s Guide
Amplifier Class
Amplifiers are classified with one or two letters. These classes correspond as a grading system for their wave functionality. For example, class A amps need uninterrupted and high-flowing current, potentially leading to overheating issues.
Meanwhile, Class B has a single-ended push/pull configuration that lessens power wastage but delivers delays. There are many more classes, but the most efficient is the Class-D amplifiers that utilize optimal power consumption. They’re also more compact, so it’s recommended if you have limited space.
Power Rating
When talking about power rating, you need to look at the amplifier’s watts RMS metric. To know how much overall power you’ll need, multiply that number with the number of subs you have in the system to ensure compatibility.
Inputs
Since you have to connect wires and cables when setting up your amp into your subwoofer system, the inputs of your chosen amp must match properly. The two input specifications you should watch out for are the low-level and high-level inputs.
