"How does it like, stay in there though?" There is a fastener that screws in behind the tweeter, looks like this: \_/ and the tweeter assembly is above that "V", the V is screwed through the bottom of the tweeter holder and hugs behind the panel the tweeter is mounted on.
originally i had planet audio componets jonathan. the mid bass sucked on them but the tweets sounded real nice. the main issue i had with them was that when i turned up the volume real loud the tweeters would cut out. i initially thought this was a power issue so i went to the shop and they told me it was a built in circuit in the tweeters that caused them to cut out to protect the tweeters from over heating. i thought this was some straight bull sh!t. i coulde never play my system loud with out my highs cutting out. so when i bought my w7's i bought those jl componets. initially i was afraid they werent going to fit the holes that the planet audio comps were in but they fit perfectly snug. another friend of mine just put his in flush with nothing holding it in the back
The JL tweeter has circuitry to protect the tweeter as well. Nearly all high end speakers have some form of tweeter protection to isolate it from DC voltage, tweeters blow easily. It's not a bad thing, though.
my jl tweeters have yet to cut out on me though. my planet audio tweeters always cut out on me, even when i only turnrd my volume up half way
i have a question for you jonathan. right now i have a crappy sony hu thats rated at 4 volts but when it was checked with a multimeter it was only two. ive been thinking about getting one of the newer 8 volt eclipse head units. how much would this help my sound quality. i know they have alot of great features, but will it make a big difference on my SQ?
I don't think you'd notice a huge difference in sound quality, but some possibly. Going from 2 to 8 will definitely cut down on any engine/alt or other noise in your subs though, if there's any at all to begin with.
