Couple Basic Questions on '10 Charger

[RiverRatXJ]

Hello everyone. I had a few questions about installing a amp/sub in a 2010 Charger SXT with the factory head unit. First off, power. Is there any problem with running off the + post on the battery (in the trunk), or do I need to go to the "jump off" post under the hood? Also, for the remote wire. If anyone has done this install before maybe you could tell me what source you used for this. I will probably just use a switched 12v on the fuse block in the trunk thats not being used. I was just wandering if there was a better option some how. Any input would be greatly appreciated! (esp. about the +) Thanks

wire to the battery, not the post under the hood.

for a turn-on, your best bet is a Charger forum where people who actually own the same car and have done a similar installation will hang out. i avoid switched ignition turn-on at all times. you don't want to be able to turn the HU off and have the amp still on.

buy an amp with an auto turn-on feature and high level inputs and you'll save yourself a lot of hassle.
