2007 Sedan HU, Amp, Speaker install

[Crackerballer]

Hey everyone. I just picked up my 2007 Yaris sedan, Flint Mica, from a friend this weekend as a daily driver to keep miles off my 2004 Cobra. I have already ordered a few things for my audio system and I will use this thread to track install and show write ups of how I did everything. Tentative list is:

• Kenwood DDX418 Double Din DVD playing headunit (ordered, Crutchfield, $400 shipped)

• Infinity Reference 9623i 6x9s (ordered, Harmon Kardon, $72 shipped remanufactured, full warranty from HK)

• Diamond Audio S600s 6.5" component speaker set, ordered for my S2000 in 2009, never installed, probably paid around $450 for them

• JBL GTO 752 2 channel amp, ordered in 2009 for my boat, ended up using a cheaper one, so I have this unused. Also bought remanufactured from HK with full warranty, paid like $80 I think

• Diamond Audio D6 450.2, ordered for my S2000 in 2009, never used, might not get used in the Yaris.

The plan is to install the headunit and go ahead and run both sets of RCAs, front and back at the same time. I will probably run them under the carpet through the center of the car to avoid any interference they may get from the door panels. I'll run my amp power wire down the door panels since it doesn't matter.

Then I will be using the JBL GTO to power the rear 6x9s. I am going to sell the Diamond Audio 2 channel amp and buy a 4 channel, then I will wire the fronts up and install the Diamond speakers. Still trying to decide where I will put the tweeters.

Should be a fun project. I have no plans for a sub or any sound deadening, just want some loud, clear jams.
