Temporary Defect – Checkout is not working correctly for a couple of the crossover kits. A new website is under development and will replace this soon.
07/02/2026, If you do get an error or zero price when attempting to order a kit, please email me, and I can email you a custom invoice.
I hope to have these structural changes completed soon.
A foolproof option to ensure you get the right crossover parts. Nothing missing. Nothing extra. No markups for the service.
We will continue to add kits and designs as they are requested. To request a crossover kit, the schematic must be provided or published.
DIY kits (additional designers and kits are being added)
Upgrades for Commercial Designs (Additional brands and designs pending)
