Best Under Seat Subwoofer Buying Guide

While making a decision to buy an under seat woofer is a great one as it saves you lots of leg and trunk space. There are a few things that you need to put into consideration to help influence your final pick.

We have them detailed here for you…

  • Power

All subwoofers are designed to add bass to your music systems and their power ratings are rated in watts and are divided into RMS and peak power ratings. You should buy one which matches and complements your current stereo ratings, as too much bass will dampen out your songs, while too little will not give you the proper effect you desire from your woofer purchase.

  • Unit Size

The size should and must be a fit with your available under seat space. Width, length, and thickness are all vital factors to look at. A unit that does not protrude from the under seat sides is usually better. One that does not require any cramping to ensure a fit should be selected over one that does.

  • Ease Of Installation

Installing an under seat woofer requires working in a tight spot with very limited space: under your seat! Easier to access speaker and power inputs preferably on a side panel of the enclosure make it a lot simpler for you to hookup or unhook cables from your stereo to the sub.

  • Ease Of Use And Control

Struggling to reach out for your woofer controls under a set is not a good option, especially if you are driving. A remote control eliminates this need and allows you to remain in controls. Likewise, an auto on and off feature is a great addition for your subwoofer. This eliminates the need to manually power on and off your subwoofer before and after each use.

  • Accessories

Buying a subwoofer that includes all installation accessories will sure save you lots of time and possibly buying the wrong accessory.

  • Quality

Great quality ensures you get better performance and longer durability. This is very important. Also important are added features such as thermal protection, overload protection and protection against power surges (short circuit protection). This gives you more confidence that you will be able to use your woofer for longer.
