Here are a few I found real quick:

This one could accept the proper ring terminals and is very similar to OE. You'd just have to buy bigger ring terminals.

A 3-way terminal

Wing-nut terminals (might have clearance issues, not positive)

this looked good to me:

save at least 1' of wire, now for about 10 more ill have to measure but i think 10' will be good!

this isnt highly flexable, but looks good, what do you think? http://cgi.ebay.com/ws/eBayISAPI.dll...ht_4158wt_1165

 

I was at audio warehouse and said 1/0 would be overkill, and 4 gauge will work fine.

should i look for 4 gauge instead of 1/0?

 

4 gauge is pretty much common now. I have 4 gauge on my Alphasonik 300watt amp. Since I plan on upgrading the amp and subs in the future, I dont have to go back to the stereo shop to reinstall the new wiring if I went with the original 8 ga wiring. I just switch out the amp and subs. Simple as that.

Personally I dont know what car you have specifically, but my 02 Neon has 2 different install kits. One which is iso-mounted (meaning the radio mounts behind the opening). and the normal kit where the radio sits normally.

 

Monster Cable has a 3 way battery post cable hook-up with a removable clear cover. I have this which I plan to use when I have the proper tools to install the cabling.

 

When you are upgrading the grounds, you are basically wanting to upgrade them to handle the output. Is 1/0 overkill for what you have? Sure, but you could upgrade things even more and not worry about it. Some people use 8 gauge, as it was mentioned above. I think unless you are going with something super extreme, 4 gauge would work fine.

 

0 gauge wiring is recommended for an amp/group of amps that run into the 2000+watt range not to mention a new higher output alternator or multiple high output alternators since most car's stock alternator arent built to handle that much of a power drain from the amp(s) Oh and be sure to have a 1-2 farad capacitor for every 1000watts of power (amp). I personally use a 2 farad cap per 1000.

 

I think i am just going to go with 1/0

is there any negitives for this?

The grounds to the body and engine look very easy.

BUT the alternator looks extremely difficult.... i can barely see the B+ nut let alone how to get to it, and where to run the wire!

also i want to upgrade the factory wire to the power distribution center with matching 4awg to look cool, plus then i will have a neat and nice looking battery terminal and good grounds

 

alpine is over rated just like jl audio i mean comeon jl who gives a **** if its an earth magnet man made is just as good why spend the extra money mining it
