Two years ago I upgraded all the stereo components behind the factory head unit/in dash 6-disc changer. For those who think Bose represents high quality, don’t let the name fool you. The Bose stereo installed by the Acura fcatory is crap. We’re talking paper cone speakers, two tiny underpowered amps and a subwoofer that will make you laugh because it burps more than it thumps.
Check out the differences between the Bose 5.25″ subwoofer and the Focal sub that took its place. One, the Focal speaker cone material is stiffer than a 15 year old finding his dad’s porn collection. Two, the surrounding material and the overall basket construction is of a much higher quality over the Bose.
Stage 1 of the upgrade included installing Accumat in the door panels and rear quarter panels, using new wires/cables everywhere, Alpine amps, a/d/s component speakers for the front stage, Pioneer 6.5″ speakers for rear fill, power and ground distribution blocks, and a hi-lo converter. Sound quality was a HUGE improvement over the Bose stereo components.
I finally got around to upgrading the head-unit because I wanted integrated iPod control. The FM transmitters and cassette tape adapters just weren’t up to par. I’ve seen my friends use them and I didn’t like the drawbacks: finding an unused FM frequency to broadcast the iPod tunes, moderate sound quality, must use an external adapter to power/charge the iPod, must fiddle with iPod to access music and playlists (dangerous when driving).
So, I went from this:
To this:
Plus, there was a noticeable improvement with sound quality after dumping the hi-low converters.
Below are some pics of the install.
Alpine V-series amps, a/d/s crossovers and Scosche power distribution blocks. The green box is the hi-low converter which founds its way to the trash immediately after I installed the Pioneer head unit.
