Yes, yes, yes! Another JBL GTO fan! I have some similarly aged GTO 603 6 1/2 inch speakers. I compared them to some Polk EX speakers recently and the Polks promptly went back to the store.
I completely, fully, 100% disagree that you can or should skimp on a speakers just because you won't have an amp.
You will want a fairly sensitive speaker for your non-ampped head-unit, and the JBL GTO series will fit the bill. I think you can find some great prices on ebay.
The GTOs will have a crisp, clear sound that some might call "harsh," but I think of them as "pure." They give me a great sound stage.
The Polks I tried had similar highs and lows, but they seriously had no middle. You could barely even hear strings or horns. They had a completely "wrong" sound, like a completely whack, triple strength loudness-button sound. My good old JBLs sounded so pure and nice in direct comparison in the same installation with the same music. I can't recommend the Polk EX series based on my experience with the EX365 6 1/2 inch model.
Infinity reference series speakers are another quality speaker sensitive enough to be run directly off a head unit. They won't sound as bright and clear as the GTO series, but they will sound nice to many ears. I tell you though, if you've worked a job around loud machinery or you used to really crank it or went to a lot of concerts as a younger gent, you will appreciate the clear highs and nice, full range of the JBL GTO series.
Try 'em. They're great bang for the buck, particularly because they sound good at the lower power levels of the HU's built in amp.
EDIT: I'm no "golden-ears," more like a "silver-ears." For example, I can't hear any difference between monster cable and plain old stranded copper wire of sufficient guage, but I certainly can tell if a speaker sounds like crap. I think mine sound great even without a sub or amp. I honestly have not heard their equal in a non-component, non-amplified, non-subwoofered setup. I've driven many new cars, luxury and otherwise, with many a "premium" factory system, and I still prefer my good old JBLs to a great majority of them.
