A client from Manchester recently visited Westminster Speed and Sound to ask about upgrading the stereo system in his 2005 Porsche 911 Carrera S. The client wanted to modernize the technology in his car with a new multimedia receiver and improve the sound of the system with an amplifier and better speakers. After talking with the client about his music and listening preferences, we invited him to audition several speaker options on our display and test drive the Sony multimedia receiver we had in mind. He loved our suggestions, so we put together a quote and scheduled an installation appointment.
Sony Multimedia Receiver Adds Smartphone Integration
We started the project by removing the factory radio to make way for a Sony XAV-AX7000 multimedia receiver. This touchscreen radio includes both Apple CarPlay and Android Auto smartphone integration. These technologies let the driver use voice commands to perform functions like making phone calls, replying to text messages or choosing the song he wants to hear. He can also get detailed turn-by-turn navigation instructions from Google Maps or Waze by asking for directions to an address or a business almost anywhere in North America. We added a USB extension for the dual USB ports and located it in the center console.
BLAM Speaker Upgrade
To bring this audio system to life, our team started by removing the door speakers to make way for new drivers from BLAM. We mounted a set of 8-inch L200P woofers in the doors using custom expanded PVC mounting adapters. Next, we replaced the midrange speakers in the door panels with BLAM LM80 Live-Series midrange speakers. The last upgrade was to mount the tweeters from the L200P set in the dash speaker locations.
We installed a seven-channel Match UP7DSP amplifier in place of the Bose amp in the front storage area. This amp includes an integrated digital signal processor that we used to set the crossovers for the speakers. Each channel of the amp has a dedicated equalizer that we used to calibrate each speaker’s output to ensure the sound is smooth and accurate. Finally, we used the signal-delay settings to create an impressively accurate soundstage that spans the dash’s width.
Porsche Stereo System Upgrade Project
After about a day and a half of work, we had the new radio, amp and speakers upgraded, and the car was ready to go back to the client. He loved the way it sounded and was thrilled with the installation.
