I am looking into replacing the factory DC-DC with a Meanwell setup. This would allow me to move it to a different location and give me the entire trunk. Efficiency would go up, weight would go down, and total space increased? Worth it!

Still looking at other weight savings here and there. I don't want to loose too many comforts, keeping full interior in tact and keeping a decent stereo is important to me. The trunk will need a makeover to make use of all the space. Might ditch the spare tire setup in place of a small pump + can of tire seal gunk (taking spare only on long trips). Lot of options in the air!
You'll want a diode or relay, the Meanwell unit will drain your battery eventually if left to sit.

This is the rectifier I ordered: https://www.ebay.com/itm/Amico-SQL-1...72.m2749.l2649

I opted for the Meanwell HRP-600-12 rather than 15, because I will likely reuse it as a 12v power supply after I finish my K conversion. If I planned to keep the car that way indefinitely I'd have used the 15.

EDIT: Have you yet read my k-conversion thread?
