I bought this car in 2016 to see how far I could push a hypermiler's dream car. After hitting a staggering 96MPG on a road trip (without the "Hybrid" part; no electrical assist is installed any longer, just the 3-bang'n 1.0L and it's insanely long gearing) and completely falling in love with this car, I figured it was time to have this car meet a hobby that I love: Car audio. Well, any audio really... but it's been a while since I've done a decent speakerbox on 4 wheels.
For years, I drove around with a minimal system: Basic Kenwood receiver, pair of Polk 6.5"s in the door, pair of generic tweets tossed on the dash, and an 8" Infinity sub sealed with maybe 200 watts in a small fiberglass box. It was great for what I paid, but I often dreamed of bigger. After having great success with my Dayton in-wall DSP build and awesome lows with my 4x Fi 18" Infinite baffle subs (10hz makes every door in my house chatter, lol), I made up my mind that I wanted something similar in my car.
Goal: Make this a fun daily driver that loves road trips. Keep the weight to minimal, but high efficiency output with awesome sound quality on a tight budget. Make it modular for upgrades in the future and insure the output is plentiful.
