Automakers' sound systems: Crank it, don't yank it

Years ago, one of the first things most music lovers did after buying a new vehicle was drive to an aftermarket stereo shop to get the crappy stock components swapped for better gear. And you'd typically get not only better sound but also more bang (and boom) for your buck. But in the past decade or so, the overall quality of OEM audio has dramatically increased, while car electronics became more complex, removing the incentive for most new vehicle owners — and all but the most hardcore DIYer — to start from scratch. In 2010, I did a comparison of the average costs for OEM electronics vs. similar offerings from the aftermarket, and back then automakers' stock premium systems were by far the best bargain — and are probably an even better value now. The premium 14-speaker, 1,200-watt JBL system in the all-new 2019 Toyota Avalon is a prime example of this trend. It's standard on the top two Limited and Touring trims and is available as a $680 audio upgrade on the XLE and XSE. I doubt you can even buy 14 speakers and 1,200 watts of amplification from the aftermarket for 700 bucks, much less have it all installed. And because the system is bundled with Toyota's Entune infotainment system, Apple CarPlay and a surround-view camera, removing the head unit means you would likely lose these features. Another advantage of OEMs and their audio partners is they can design the car around the audio system. In the past, automakers would typically place speakers where convenient for packaging, not for optimal sound reproduction, and audio engineers were forced to compromise. But as with the Avalon's premium JBL audio system, this is starting to change. At a recent behind-the-scenes peek for media into the process of developing the system, Toyota and Harman engineers delved into the minutia of sealing the inner panel of the front doors to create an enclosure for 6x8-inch woofers, making space in the pillars for JBL horn tweeters and extensively measuring the acoustic properties of the interior to tune the sound to the space. I'm met some creative and skilled car stereo installers, but none with a degree in psychoacoustics. The system is also the first to feature Quantum Logic Surround that creates a multi-channel listening experience from two-channel sources. And it includes Harman's Clari-Fi processing that "rebuilds key details lost" in compressed audio formats used by streaming music services and MP3s.

2014 Chevy Malibu, Buick LaCrosse recalled over brake mix-up

The recall madness over at General Motors isn't letting up anytime soon, as evidenced by this latest call-back of 8,208 Chevrolet Malibu and Buick LaCrosse sedans. For those keeping track, this is the fifth recall that GM has announced in the past two weeks, not to mention the massive ignition-switch issue from earlier this year.
GM issued a statement saying these sedans are being recalled due to "possible reduced braking performance," according to Automotive News. The problem? Rear brake rotors may have accidentally been installed in the front brake assembly. And since both cars use more robust braking systems up front than out back, braking power could be reduced, increasing the risk of a crash.
Automotive News reports that, of the over 8,000 cars being recalled, about 1,700 are currently in the hands of customers, while the others are still in dealer inventory. GM is unaware of any crashes or injuries related to this problem. All of the affected vehicles are from the 2014 model year.

Trump prods General Motors over its auto plants in China

WASHINGTON — U.S. President Donald Trump, who is engaged in a trade war with Beijing, said on Friday that the largest U.S. automaker, General Motors, should begin moving its operations back to the United States. "General Motors, which was once the Giant of Detroit, is now one of the smallest auto manufacturers there. They moved major plants to China, BEFORE I CAME INTO OFFICE. This was done despite the saving help given them by the USA. Now they should start moving back to America again?" Trump said in a post on Twitter. Trump appeared to be referring to a Bloomberg News story that reported GM's hourly workforce of 46,000 U.S. workers has fallen behind that of Fiat Chrysler as the smallest of the Detroit Three automakers. Over the past four decades, GM has dramatically cut the size of its overall U.S. workforce, which numbered nearly 620,000 in 1979. GM did not directly comment on Trump's tweet. "GMÂ’s China operations are not a threat to U.S. jobs," the company said in a fact sheet, noting that its joint ventures have sent $16 billion in equity income to GM since 2010 and that it has invested $23 billion in U.S. operations since 2009. GM's U.S. hourly workforce has fallen by about 4,000 jobs since the end of 2018 to about where it was a decade ago. Trump's ire with GM comes as contract talks with the United Auto Workers union with the Detroit Three automakers intensify ahead of a Sept. 14 deadline. Trump has previously attacked GM for building vehicles in Mexico and for ending production at plants in Michigan, Ohio and Maryland and threatened to cut GM subsidies in retaliation. GM's decision to close four plants in the United States is a central issue in the contract talks. Trump has made boosting auto jobs a key priority and has often attacked automakers on Twitter for not doing enough to boost U.S. employment. His 2020 re-election bid will hinge on holding key industrial battleground states like Wisconsin, Pennsylvania and Michigan that narrowly voted for him in 2016. China is the worldÂ’s largest auto market, and government policy favors automakers assembling vehicles there, and not importing them from overseas. In response to TrumpÂ’s latest tariffs, China said last week it will reinstitute 25% tariffs on U.S.-made vehicles. The U.S. is imposing 15% tariffs on more than $125 billion in Chinese goods starting Sunday. GM sold 3.6 million vehicles in China last year accounting for 43% of its worldwide sales.
