Fully Installed
So, it took me about 4 hours and change on the install.
The biggest challenges.
1. Getting the harness across from the kick panel to the deck. I ended up using fishing tape to help (that sped things up)
2. Tucking the rear harness between the right rear panel before it comes across, it's a very tight corner.
Overall, very impressed from customer service to the completeness of the install instructions and video. I've pulled apart a 4 runner before so that helped.
Overall Thoughts. (don't have the 6 x 9's yet).
1. Sound Quality - it's quite good. Soft domes I always feel are a good call in cars, particularly by the dash. The bass is solid. Not a boomer as many have mentioned, but plenty for me. The system reminds me of the Harman Kardon System I heard in a BMW recently. Maybe a tad more bass than that, but a good system. My brother has the JBL system in his Limited, I think this sounds better overall. (the JBL I find to sometimes have a "tinny" sound to it.
2. I probably would have designed the system with a 10 inch woofer, really only because I don't think it would have posed an issue. But honestly it's not remotely a make or break thing. If you are not doing competition audio, want a clean, excellent sounding system that is overall very stock looking - I would tell almost anyone that this is the way to go.
3. I have a serious high end system in my home, and in my car I don't need competition level audio. But this really is a good sounding system.
4. Cost. So if I look at what 1600 bucks could get me - could I get "better" components - maybe. But it would NOT have a clean custom box like this, along with an amp, all cables, and the install. Sure, I did the install and that saves a ton of money. But this is really a smart system, from having the amp mounted under, but attached to the seat, to the harnesses (I can't say enough how much easier that makes a job like this). Cost wise, I don't think you could come close to this sound, and integrated look for 1600 bucks.
I'm impressed, and would not hesitate to recommend or buy the system again.
I don't know that the 6 x 9's will change a ton, possibly tighter mid-bass. The one thing the stock 6x9's can do is put out a fair amount of mid-bass (it's one note, it's bloated, it's not tight, but they stock speakers can do that).
If you are on the fence, and don't mind 4-6 hours of your own time to do an install - just order this system.
