Hi guys,
Long time reader on here but thought I’d contribute with something I actually have expertise in. I am an audio engineer and design and build recording studios as well as the majority of the electronics that go into them.
I bought my 02 X5 4.4 about 3 years after missing my e39 540i but wanting an SUV for ski trips up to the resorts here in Southern California. Car came missing the headunit.
I added a Dynavin headunit, and gutted all the DSP amps and DSP sub in the back. I ran pre outs to a JL XD v2 700/5. I had 5 channels available. I also disconnected the tweeters in the A pillar and replaced the mids in the dash with the Vifa mid. I figured these would be good after seeing recommendations on here and Vifas specs looked good as well as experience using their units in many pro speakers. Stock BMW woofers. I tied Left front+rear mids together into JL Amp Channel 1. Tied right front +rear mids to Channel 2. Left woofers to 3, Right woofers to 4 and custom made JL 10w6v2 box and sub into Channel 5.
The amp is configured with 1+2 Highpass at 500Hz, 3+4 set to Band pass, 5 to LowPass one click below 80Hz. With this setup crossovers work well enough I don’t find a burning urge to setup any additional crossovers and this system hits hard, tight, clear and clean.
I custom built the sub box. It is a challenge to fit the big full size 10w6v2 back there. Box is stuffed to the gills with OC 703 fiberglass board. Picture attached to the link.
