This really isn't vehicle specific, but in case it matters, here's the specs:
1993 Chevy S-10 Blazer
3.6L Vortec V6
~180k
OK, so I've been trying to hook up an amplifier to my battery (ended up blowing something by connecting the hi-power-in ground to the power wire... but that's a totally different problem). My problem is that the bolt is far too short in order to really put anything in there (no matter the size. It just doesn't fit). When I put, say, a terminal lug on there and try to tighten the bolt, it doesn't even catch in the battery. I was looking for some sort of extender I could make or buy, but everything I find doesn't seem to apply (I don't want to take apart the existing terminal, which it would seem I would have to do in order to put a new bolt in there).
So, can anyone suggest a place to look for something like that for my
blazer? I can post pictures of the positive connector if you need to
see what I mean.

Just attach it to the main terminal of the starter. that gives you the same thing. It's going to need some type of fusible link for protection there also.

A performance stereo shop will have the right stuff and most will give tips on doing high amp stereo installs. make a little mistake and it will cost you mucho dinero.

Not sure what or why he/she is up to with this? Any NAPA or parts outlet will have an assortment of longer bolts for the DECADES of GM using them on all their vehicles.
Some were to accommodate two cables if equipped with two batteries, on one of my own a plow uses a TON of power as it's all electric controlled so has different than the small OE bolts.
For most purposes this should have power available at the fuse box marked "ign" and another "bat" which are enabled by ignition being on or power anytime. EITHER WAY OR WHATEVER WAY you get power you must use a fuse. They sell wire ready to take fuse of choice and do that as close to source of power as possible.
Watch out when a longer bolt is used if you go that way that it doesn't touch or can't touch anything to ground out. If you do fuss with the battery positive directly DO have the negative post removed as the silly wrench will become a short if it touches the wrong metal.
What are you up to anyway? Make sure you use proper gauge wire and not over-fuse it for the project you are taking on,
T
* Here's an example of wire that holds the spade type fuse in line. Can be had for full size or the mini ones.......

Sorry guy's , I was not trying to do an end around on you.Both gave solid advice for NORMAL stereo's.Quess I took a worse case senerio.My son is part owner of a car stereo shop. We are not talking 3-5 amp amplifiers. My sons ride for example. Twin eight thousand watt amps with crossovers with dual 1000uf caps for surges. They power ten 15 inch subwoofers eight mid range and four tweeters. All this is powered by dual 1100 cca gel cell batts. Charged by (2) 200 amp custom made alternators. Wired with 00 gage stranded copper silicon jacketed cable . A 60 amp resetable breaker on each batt . This THING can and has blown a windshield out. PLEASE dont ask me why. The moral of the story is i have seen kids destroy their wiring and or car by being a wanna be and try similar stuff with 12 gage batt cables and a inline 15 amp fuse.. Yall were right to start small till he stated his goal.

Hah, small is what I needed. I have 8GA wire with a 50A/60A fuse (not sure which it actually is) about a foot from the battery terminal. And the amp I have is only drawing 15A (plus I have a 10A stereo on 12GA split from the 8GA with its own 10A fuse inline). The only problem is that I can't connect the wire to the battery using conventional means (meaning with a lug terminal or whatever) because there isn't enough bolt there to go through a lug connector (of any size) and still be able to lock to the battery. And before you say anything, the positive terminal is one of those enclosed plastic/rubber things with the bolt sticking through it. I can't remove the bolt or change it or whatever without totally redoing the whole wiring scheme to the positive terminal, which I don't want to do unless it's the ultimate, last-ditch, can't-be-done-any-other-way option (it's really tight in the engine compartment and I have very little slack in the positive power lines).
So, that said, an suggestions?
@re-tired: that bolt is one of the first things I saw, but like I said, removing the bolt I have is nigh impossible. What I really want is something to screw the existing connector into that would then go into another assembly that has a longer bolt/better connection option.

Malkierian Im glad (I think) that I over advised you . As for the aftermarket bolt , the factory bolt is designed to POP out of the red rubber cover with a twist and pull . The replacement fits in its place with extra wiring going on outside with supplied nut. Of course there is plenty of merit in Hammer's and Tom's answer's. BTW ....Glen Miller's "In the mood" sounds awesome on my son outfit.

When I put the amp in my Suburban I got an Optima battery with dual posts so I could put the amp directly on the battery with its own connection. I know sometimes these bolts stick in there a bit and seem like they won't come off, but work it a bit and it will. The connector RT showed you would do quite well for you. Good luck with the system.
