I got this old Punch 50.1 from 1998... rated at 100W RMS @ 2 ohms but it comfortably does around 350W RMS @ 1 ohm so I think it's worth it for me to fix it.

It has double terminals... (double power, double ground). The threading on some of the terminals themselves is somewhat stripped/deformed...

I'm wondering if I could rethread the terminal to fit something else rather than an hex bolt, maybe something with a Philips head for convenience and since the old threading is useless for most of the terminals. I've been suggested to use tapping bits to do this...

Has anybody else done this before? How durable is the thread that you carve out in the long run?

I got some new terminals from http://www.freemanscarstereo.com/ for my old Punch 200, then got Radio Shack to put them in for me. That is one option.

A properly tapped thread is as good as any other

just get a tap the same size as the current thread size, and it should just repair the current threads...

Alright... sounds good... I'm probably gonna upgrade to all brand new hex screws too then because some of them are missing and some are stripped as well.

Canadian Tire has the hex screws in their "entertainment unit" repair part of the store here, so check them out.

edmonton nut n' bolt, its on argyl
use a botteming tap, dont forget the cutting fliud

you dont need cutting oil or cool tool for just repairing threads...

dosent hurt if you have it around the shop
