The renderings looks great. The name threw me for a loop a bit. My grandfather (Laymond) had a twin brother named Raymond. So obviously I like the name
As far as the stereo, the nice thing about these trucks is there is little cabin space, so it won't take much in quality components to sound good. Over the summer I ran a pair of 4" RF Punch speakers in the dash with matching 6x9s in the doors (already cut) going to a RF Prime 75x4 amp running directly off my phone. Sounded better than I expected.
Now that my project is taking a turn, I'm going to relocated speakers into the kick panel and going with good quality 6.5" components (RF more than likely as I get them at cost and like their quality). Not sure yet if I'll mount the tweeters there or up higher. Pretty sure I won't mess with rear speakers as I don't see much for good sound as the seat backs would muffle the sound. I'm also leaning towards doing something with 8" subs behind the seat to round out the sound.
