Great Idea, FrankieHey everyone!
I know this thread is old, but its a great thread!
I've owned my RTL less than 2 weeks and this was one of the easiest and cheapest upgrades/modification I found to use.
When I first bought the truck I kind of felt the stereo sounded muffled. So when I saw people raving about the tweeter difference I gave it a shot.
It definitely wasn't 15 minutes for me, but still do able within an hour. Takes so long because of the confined space against the windshield.
Anyway, I decided to record the differences to compare.
I did a PRE recording, with the stock stereo, switching through channels to get a mix of music.
Then a MID recording - with driver side tweeter installed.
Then a POST recording - both tweeters installed and all completed.
A few things to note: On the POST, I messed with the sound levels still trying to find that sweet spot. I think the the MID recording does the best of showing the differences.
Second note, is I recorded with my cell phone (Note 4) and its known to lower the bass when recording. So there are times when the bass sound hollow or off - that's completely my phone, not the truck.
I bought the Cadence tweeters (Amazon.com : Cadence Acoustics ZRS75T 1-Inch 200 Watt Peak Hybrid Tweeter : Vehicle Tweeters : Car Electronics)
So here they are:
PRE TWEETER SOUND CHECK
MID TWEETER UPGRADE SOUND CHECK
POST TWEETER SOUND CHECK
Hope that helps anyone on the fence about the upgrade and thanks to laserguy for the thread and everyone else who gave advice and suggestions!
