Damn, the next one we do I am calling you 727kid! You are cheaper than my installers! You and Dalton (Notladstyle) are the whores of the audio world!
Just kidding. I understand budget and travel time and I have to say that the 727kid has posted up some clean work. I am sure he will do a great job. If it doesn't work out with schedules, you know we are about 15 minutes away and we'll take care of it if you need us.
But, $20 for the connectors? If that includes pro level battery terminals, 4-6 gold 0ga. ring terminals all of really good quality it still seems just a little steep. We sell all that plus the 100 amp ANL fuse and HUGE ANL fuse holder under the Tsunami or Raptor brand for $25 over the counter. We'll usually even throw in the heat shrink.
If you get time, post up befores and afters becuase this is something people ask us about constantly. I think a visual of some good work will make a great reference for those that don't understand this upgrade.
