Showcasing the Best in the Mobile Enhancement Industry
A while back, we examined the difference in sound quality between wired and wireless Apple CarPlay. Now that many Android-based smartphones have access to additional audio streaming codecs like LDAC and aptX, it’s time to check out how they perform in terms of signal accuracy and frequency response. We’ll use the Sony XAV-9000ES digital media receiver we tested in May 2024 for Read more
When 99% of car audio enthusiasts think about a digital signal processor (DSP), they associate it with equalizers, crossovers, and signal delays. In more advanced solutions, a consumer-grade car audio DSP might add the ability to include all-pass filters, an upmixer for a center channel and signal summing. However, at an engineering level, much more is available. Let’s look at Read more
As time goes on, everything seems to get bigger and better, doesn't it? Back in the '80s, I remember thinking that having a car with 15-inch wheels was pretty cool. Now, trucks and SUVs roll off the lot every day with 21- and 22-inch wheels. Having a 25-inch console TV in your living room used to be cool. Now, we’ve got screens over 100 inches available from discount stores. Read more
Recently, we were sent a link to a YouTube video in which someone was trying to make power measurements of a factory-installed amplifier on a motorcycle. We see videos like this all the time. Unfortunately, the numbers presented in these videos are not just inaccurate but often completely illogical. Let’s talk about how we make power measurements and what information some of Read more
In late October 2023, we had the opportunity to give the Rockford Fosgate R2-1200X1 subwoofer amplifier a thorough Test Drive Review (https://www.bestcaraudio.com/test-drive-review-rockford-fosgate-r2-1200x1/). We were very impressed that this entry-level amp had features and performance that dramatically outperformed entry-level and mid-level products from other brands. Power Read more
A plethora of source units and digital signal processors are available for car audio systems, each with its own unique features and performance capabilities. Our lab team, while working on a client project, came across two digital-to-analog converters that stood out because of their dramatically different performance. The process of converting a digital signal to an analog Read more
A while back, I published an article that compared a high-quality Class-D amplifier with a low-quality “internet-brand” Class AB amp to prove a point about topology not being the deciding factor in performance and accuracy. The contrast in their performance was shocking, with the Class-D amp besting the AB in every way. An amateur YouTuber made a video breaking down the Read more
Buying a new car radio has been challenging for most of 2021 and so far in 2022. The scarcity of computer chips has made picking up a name-brand radio from Sony, Kenwood, JVC, Alpine or Pioneer difficult or impossible. If you have to have a new radio in your vehicle, you’ve had two choices: wait patiently or buy a less popular option. I’ve heard good things about the short-term Read more
If you've been into high-end car audio for as long as I have, then you have fond memories of source car audio source units like the famed CDX-C90 from the late ’90s. While the RSX-GS9 media receiver is an amazing option, consumers have been craving a multimedia solution with CarPlay and Android Auto smartphone integration. Thankfully, the Sony product development team heard Read more
