The modern stereo system

I had a nice sounding system installed in my 2008 GMC 2500HD. First things first though. The electrical system needs to be upgraded to handle the amp draw of your system, the interior of the car needs to be removed and replaced to install sound dampening panels and insulation under nearly every surface and the positioning and proper mounting of of the speakers needs to be carefully planned.

I upgraded to a 200+ amp alternator, heavy 0 gauge cabling and a dedicated AGM battery to supply adequate and nearly instantaneous amp flow.

Component selection depends on your budget. I used a Zapco HDSP-V digital processor and 4 Z-AP amps driving a pair of Hybrid Audio Technologies Legatia X1 tweeters mounted in my A-pillars, 4 Legatia X6 7.1" wide band carbon fiber mid-basses mounted on an infinite baffle on my doors and 2 Clarus C12SW subs mounted under my rear seat in a custom enclosure.

I subscribe to Tidal music service which streams digital, CD quality and above music via bluetooth to a Pioneer double din head unit.

The combination of quality components that are properly installed and powered in a well prepared environment makes an incredible combination and is capable of producing stunning clarity, fidelity and performance.

The bottom line is the car interior preparation, sufficient 12V power supply and the installation is critical to getting the most out of any car stereo components you install.
