Yaris Sedan Deadening and Sound system upgrade

[Alien Mantis]

I must say, you guys have really been doing some amazing stuff.
I had to catch up on this whole thread, took me awhile to read it all.

I see you have been working on so many of the finer details.
I was surprised to see Derick was running those small sub drivers. ( Those i6SW )
I thought is was also interesting to see you guys playing around with tweeter mounting angles in the A pillars and bouncing it off the windsheild. I was never a fan of aiming tweeters at the listener. I'm a fan of off-axis tweets. Tweets can be harsh anyway, why aim them at your face!

SQ: you are definately pro-level. Gratz on your work so far. I see about 4 or 5 of you guys on here that really take it to the next level. That's your "thing". I respect that.
You know me, I appreciate hi quality audio but never saw the sense in spending alot of money on a really high end car audio system, but if that's your hobby, nothing wrong with it.
After I did that modest system in my Yaris, I have been listening to it and living with it since you last seen me on here. I am about to make a few changes to it. It has been great, and I have been enjoying it, but it has a few minor issues that have been bugging me, and I will try to address them.
I am on step 3 and you guys are on step 1,249.

You guys put so much work into your systems. I see you are still fans of the HAT stuff.

SQ is going to laugh at me: one of the changes I am going to make to my system is I am ready to ditch that TypeR 10" sub in the slot-ported box. For my type of music, it just doesn't nail it. If I listened to rap, jazz, techno, hip-hop, or country... it would be okay. But it isn't really cut out to play the tight fast beats of power/prog metal.
As SQ once said, the TypeR is an SPL pig. I never forgot that. And you were right. I still say the TypeR is a great sub. I'm sure my box is more to blame than the sub itself. I could put a pair of TypeR tens in a sealed box and be happy with them. But they take alot of AMP to push them. They are power hungry, especially the new ones.
My other issue is ROAD NOISE. My Yaris is just too noisy. So I am going to try and do some sound deadening. Nothing fancy, just something that will help a little bit.
I know you guys are experts on this subject, so feel free to offer a suggestion or two. I would appreciate it.

Keep up the good work guys. I came back here just to see if you guys had actually FINISHED your cars, but as expected, you are still tweaking away on them! Always something else to do. Always a new trick, or a new piece of hardware huh.

SO, since I left, what has been the biggest challenge with your systems?
What is your favorite amps now? How much farther do you need to take your system to get them to where you want them to be?
Derick, what is YOUR goal? Are you going to compete with your Yaris?
