I've got a few BNIB sets of 1/0 power wire kits made by TruConnex (Metra). I included a side by side picture of knukonceptz kolossus 1/0 OFC vs 1/0 TruConnex OFC for a size/flex reference.

I'm located in Ottawa but i am willing to ship and i have plenty of feedback/references, pm me for more info.

$110 for a OFC power wire kit
$80 for a CCA power wire kit
