what kind of bolts to use for sub to amp connection?

[IgnoreMe 5,000+ posts]

not sure if this belongs in enclosures, or general, or electrical. so ill put it in here.

either way. im talking about these:

im basically wanting to go with this approach however...what kinda bolts do i use? yes bolts are bolts, but im wondering, do they all have some kinda of coating? are am i safe with just picking a nice shiny bolt?

basically i just dont want to add unwanted resistance using this type of connection.

for anyone that doesnt understand what the picture shows, its basically each terminal wired up to a bolt and then you can either series or parellel the driver outside, without ever having to take the sub out and mess with the on board terminals

i used brass on one of my boxes and seems to work fine...

if there thick bolts theres no need to worry

I really doesnt matter.

Ive seen people say copper/brass works better than everythang. But when Test on tl, it showed no gain what so ever.

well i heard that galvanized is shitty as hell for this. but again that was from only 1 person.

if i find copper i wont worry. im just wondering if the cheap bolts are made of some material that will cause a rise in my resistance, like the way a bad ground has excessive resistance.

Ive heard alot say, dont do it, but Ive seen ALOT of people do it.

Its semi big in SPL cause u dont hafta pull teh sub out teh box to change resistance.

I doubt itll change resistance much by using any bolts.

I use stainless steel on the boxes I build and have never had any problems...

read a little bit about stainless steel. seems to have a good conductivity. looks like thats the ticket then.

you could use plumbing bolts... iirc they are copper...

lol... well in the plumbing section the bolts used to hold the crapper down.
