I cannot speak for JBL's coax speakers, but I've ran a small 10" sub by JBL a few years back, threw it in a Sonoma that my father was letting me borrow for a short time between vehicles. He's still rocking it to this day and that was about 5 years ago now, sounds great!

Cool . I'll probably run them then. They've got to be better than my lanzars . I mean I only paid 20 bucks a pair anyway. None of my speakers worked when I bought the truck about 4 years ago. And that's just what I could afford at the time. Also, a side note, I'm running two massive audio 12s at 1400 watts rms. Lol

Speaker suggestion
 

I've always used Polk audio for all my door speakers and subwoofers. They sound great and their marine grade so a little water won't ruin them. I'm pretty sure the cost for all my door speakers and sub was around $300. I went ahead and sprung for a top of the line polk sub.
