I just wanted to post up and say I finished my install the other day and am very happy with the results.
The headunit install was a piece of cake. I did spend about 8 hours on the steering wheel control adapter (ASWC-1) and it turned out it was defective so all my troubleshooting was just wasted time. Otherwise, the thing installed perfectly. I soldered everything, no crimping. I installed the "MicroBypass" and it works great.
Pioneer AppRadio 3 SPH-DA110
Metra harness + Metra antenna adapter + Metra Axxess ASWC-1 + Metra mounting kit.
JL Audio Stealthbox for 2012+ Tacoma
JL XD700/5 Amplifier
JL C5-650x component separates w/ crossover (front)
JL C2-650 2-way (rear)
JL remote control knob for amp
Kicker RCA interconnects
Stinger speaker wire and fuse.
Home made brackets for the doors :P Yes, those are walmart cutting boards. CHEAP! Worked great.
I think the install took me about 25 hours total. Yeah that sounds like a ton, but I had some set backs and I enjoyed the work. I did bits and pieces as I went last week. The brackets I got online said 6.5" and they didnt work. JL stuff is 6.52". I tried sanding, heating, etc. wasted a ton of time on that. Then twice I didn't have enough speaker wire and had to go get more. Then I installed the crossovers in the door, then changed my mind and put them in the kick panel later, so re-working that wiring.
I am very happy with the AppRadio3 and my iPhone 5. Sure there are issues, but overall its slick. I love the waze integration. Pandora works great and so does a2dp bluetooth.
The JL stuff is nuts. I tuned it per the manual and so my max volume is 40, had it at 30 and got the proper voltage. They say based on this if you go to 40 (MAX) you may get clipping occasionally. Listening to it at 15 its loud as F*CK already The stealthbox hits hard. Too hard. I dont like it at max, its just a huge bass slamming system. I am not in to that. I love the knob to be able to control when I want more or less, and i never give it 100%, its just obnoxious.
I ran the RCA's, the remote wire, and the HDMI+Pioneer proprietary iPhone5 cables down the center console. Power went down the left (driver) side, back behind the seat and over. Ground is to the huge bolt that secures the middle seat belt in the rear seat (was tough finding a ring terminal big enough but i did). speaker wire up left/right sides. Crossovers in the front are in each of the kick panels on the sides with 2 sets of speaker wire going through the door (fun fishing that, sheesh!)
The Pioneer AppRadio only has *2* sets of RCA preouts. I set one to Front L/R and the other to sub. The set of RCA's for Front L/R splits at the amp to Front L becoming Front+Rear L, and Front R becoming Front+Rear R. I have no fader control on the headunit, so I must use sensitivity on the amp. Honestly, I tuned it and I dont see myself touching it again. I wanted the sub to be separate RCA's.
I think I was a but OCD on my connections. Even the spade connectors for the speaker wire, I crimped using a crimper, then solder wicked in to the connector for a sure absolute solid connection. Overkill.
I posted up a quick video about 2 weeks ago when I installed the headunit (did the headunit and later did the speakers like a week later). Showing the AppRadio and how it works with Waze, Pandora, etc. Basic... http://www.youtube.com/watch?v=7lECmOeCc6I
Anyhow, heres some pics
