As most of you know, the base audio system from BMW leaves a lot to be desired, especially for someone who appreciated a good system.
For those interested, here's what I had done:
JL Audio CleanSweep®
CL441dsp OEM Audio Interface
BSW Stage 1 upgrade for front only (upgraded 4" speakers and addition of tweeters)
Swapped under-seat 6.5" speakers for factory Hi-Fi 8"
Above two powered by a JL Audio XD400/4 amp
JL Audio Stealthbox®
containing 2 JL Audio 13TW5-3 subs
Subs powered by a JL Audio 500/1v2 amp
Should be thumping!!
The guys at Soundscape Car Audio in McKinney (http://www.soundscapecaraudio.com
) did an absolutely amazing installation job! The amp rack was completely custom and much more than I was expecting. They made the cover to resemble the look of the door panel complete with curved wood trim!
The sound quality of the BSW upgrade speakers is awesome! A huge improvement over the stock speakers. And the Stealthbox produces really good, clear, hard bass. Here's a couple pics of the Stealthbox and amp rack installed. Enjoy!
