Alpine stereo major upgrade:
Money may or may not be an issue to some, but for me it is and all things considered I went for budget / sound quality.
I did alot of web searching on different components, specs, price, etc...
Ordered some of the things in my list (even had to return a couple do to fitment issues) and eventually came up with what I have now. Here's the details:
Dash speakers (corners): Infinity Kappa Perfect 300m 3.5" Mid-ranges (center left as-is)
Front doors: CDT Audio CL-69S 6X9” mid-bass woofers
Rear doors: Infinity Reference REF-9622IX
Sub box under rear seat: (MTX dual 10" enclosure) with JL Audio 10w3's - (10w1's were replaced)
Front door pillars and overhead: Hertz Energy ET 26.5 Tweeters
For processing, interfacing, and amps:
JL Audio HD 900/5
Kenwood Excelon XR600-6DSP
iDataLink Maestro ADS-MAR
iDataLink Maestro AR-CH2
