It’s fine to self tap a 4 gauge wire with 3 screws. “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...

But if they can’t figure out how to do it, don’t let them talk you into self tapping and just say you can handle it and then just cut a big hole to stick your arm through so you can ground your amp(s) and/ or battery. “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...

But if you can find a way to nut and bolt that wire, nut and bolt it. Don’t worry about hidden holes under you trunk’s carpet, worry about performance. But see if you can get a professional mechanic to nut and bolt each ground without having to cut the trunk’s floor. They know how. If not, then cut, nut and bolt on the 1/0 gauge grounds and self tap the 4 gauge ground. “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...

1point21gigawatts Posted August 29, 2020 Report Share Posted August 29, 2020 Make sure the battery grounds are 18” or shorter too. That’s important. “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...
never knows best Posted August 29, 2020 Report Share Posted August 29, 2020 i thought for sure that image of the grounds was a joke... but it's a vid from sonic electronix... do they have a video on how to remove your palm from your face? i need that vid Link to comment Share on other sites More sharing options...

I know for a fact. Not video experience.

Use some of that actual experience hehehehe Link to comment Share on other sites More sharing options...
1point21gigawatts Posted September 1, 2020 Report Share Posted September 1, 2020 Let me guess, I remember hearing smart people talk about this subject, here I go... shorter wire equals less resistance. Less resistance equals more/better current flow. Did I get it right? Please tell me I got it right. Lol! “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...

So, 18 inches is just a arbitrary length? maybe like that's just a old wives tale that boomer mechanics say? Link to comment Share on other sites More sharing options...
