What size tech flex is best to cover 1/0 power wire? And also, what size could I use to wrap a run of 2 12 gauge wires (mids and tweets)? I figured I'd put them both in the same tech flex as long is it wasn't too big of a PITA.

Also, how do you guys terminate your positive battery terminal wires? I'm trying to figure out the best way to do this with the 1/0 and all the other stock wires. I'm going to do the big 3 but there are still a few wires that need to be terminated as well. (pics would be awesome!)

Lastly, what spade terminals do you guys use for terminating 12 gauge wires? The EFX ones look decent but I can't seem to find them. I need them to connect the speaker wires to the crossovers for my components.

Thanks!!! And here is my list so far:

Head Unit
JVC AVX-800 head unit (bought and installed 1yr ago)

Here's what I'm installing soon...

Front Stage
ID ctx65-cs components (powered by the JL in bridged mode)
JL 300/4

Rear Fill (for when I have passengers)
MB quart components
old school Soundstream Reference 200

Substage
2 ID10 v3's wired to 1 ohm
Hifonics 1206D

120 square feet of sound deadening
Mainly KnuKonceptz wiring


Down the road stuff:
-Better sub amp - Possibly an old school Sounstream Class A6.0 that I have (just needs repaired), or an Audison.
-Going Active - Tweeters ran by an old school Soundstream Reference 300 (another one that needs repaired), mids ran by existing JL 300/4
-Processor (maybe a RF 3Sixty.2)
-Upgrade the front stage speakers.
