One of the first things I noticed about the audio in my stock 4Runner was the boomy bass and muffled mids. I've been playing with "higher" quality DACs on my computer (targeted for the home recording studio market) and went back to a component stereo system at home over the last few years, so I've become accustomed to what a decent stereo should sound like to me with the EQ set flat. In the 4Runner I had to decrease bass two notches and bump up the mids two notches to get a tolerable tone. After reading this thread and a few others on this forum about the Focal IS 690 TOY speakers, I decided to give them a shot. Bought them from Crutchfield along with a set of trim pry tools. Did the install myself after watching the YouTube video posted earlier in this thread. I did NOT use any sound deadening materials. Just pulled out the factory door woofers and dash tweeters and dropped in the Focals. For me, the difference is HUGE. With the EQ set flat, bass is now tight, the mids are clear and brought forward and the highs are very clear as well. I can actually hear the individual instruments on the tracks that I've been listening to since the install. :rockon:
Quick question for those of you who installed sound deadening material: Did you install it on the inside of the door itself (on the back side of the exterior skin), over the area directly behind the door panel that has the clear plastic or both? I had read some of the materials can make maintenance inside the doors very challenging and am interested in opinions. Thanks!
