it dont hurt the voltage none, i drop a whole .7v full tilt! im not the only one that uses those, i got the idea from randy aka Assman on SMD forums, and i no a lot of ppl that use em on there too. there niice when it comes time to have more than 1 run on 1/0 wire. which i will have in the near future. its coverd up by the seat neways. i do plan on covering the wires, just still debating on how i want to that. but for the most part this is finishd.
