Couple of amp/speaker wiring questions

[TxFireman1972]

Lining everything up for some stereo upgrades. Have a couple questions. Some of them have been asked before, but wanted to put it out there again to make sure.

Power Wire:
The Amp I'm putting in (JL Audio HD900/5), uses a max power wire and ground wire size of 4AWG. Am I ok running 4AWG all the way from the battery to the amp, or would it be a good idea to run 2AWG from the battery back to a distribution block, and then 4AWG from the block to the amp?

Speaker Wires for Components:
Going to be running a set of Hertz HSK165XL components. Whats best wire size and type for:

Amp to Crossovers
Crossovers to speakers

Also curious where everyone is mounting their crossovers. I went with the JL 900/5 because I like the compactness of it and don't really want a whole mess of stuff mounted under the seat. So let me know where you are mounting crossover, pics would be great.

your fine to run 4awg from battery to amp, thats how my system is. you prolly have one but just to make sure to have an inline fuse.

16awg will be fine for the door speakers, but if you want to, 12awg would be great. wouldnt notice a big difference between the two

What about crossovers? Everyone just mounting them on the door?
