Very dumb question on wiring an amp..
When wiring the amp, to power it up, I guess its the positive cable? I know I run it through the grommet through the firewall behind the PCM, but where do I run it to? The battery? I heard that could run your battery dead, I also heard the fuse box... but someone also said that is bad...
Also where can I buy some wire for the Sub to Amp? any certain kind?
heres some pics of what I got (bought from a member on here)



the large red wire with the fuse on it goes to battery/fusebox... blue wire goes to HU and to the amp, the red audio cables go from the HU to the amp, and the thick black wire is ground Right?
