For car audio enthusiasts, especially those interested in competing in SPL competitions, amplifier efficiency should be one of their primary concerns. In this first of three articles on efficiency, we take a close look at the Rockford Fosgate M5-1000X1 Class-D subwoofer amp and analyze how well it makes use of power at different output levels. […]
If you’ve looked at new car pricing and availability in the last year, you know that getting a deal on the car or truck of your dreams is a fantasy. The shortage of electronics and computer chips has made manufacturing new vehicles extremely difficult. The ones that do make it to the showroom floor are […]
Consumer reception of the new Sony Mobile ES speakers has been incredible. These solutions were designed to offer benchmark performance at very accessible price points. A while back, we looked at the 6.5-inch component set and coaxial speakers. In this BestCarAudio.com spotlight, we’ll check out the features of the XS690ES 6-by-9 and the XS-680ES 6-by-8-inch […]
If you’ve been around the car audio scene for a few decades, then you’ll recall a time when almost all amplifiers doubled their output power when the load impedance was halved. For example, an amplifier might have been rated to produce 75 watts per channel into a 4-ohm load and 150 watts into a 2-ohm […]
In the first week of May 2021, Sony Electronics introduced its new Mobile ES series of speakers and subwoofers. If you’ve been into the car audio industry for a while, then you’ll recognize the Mobile ES (Elevated Standard) name from classic products like the CDX-X90 CD player.

Not long ago, we looked at how an increase in subwoofer voice coil temperature reduced the power delivered from your amplifier. With component temperatures easily exceeding the boiling point of water, the impedance of the voice coil can increase by more than 50%. Manufacturers that understand this go to great lengths to include technologies to […]
