my opinion/comment is......
you were going to buy stuff online, I imagine because you wanted to save money. If this is the case then I dont understand why you are now going to go the JL route. Granted they are high quality and you probably do get what you pay for, but if you look at brands commonly available in retail stores/stereo shops then JL has to be just about THE most expensive brand out there.
1stmp3 will probably punch me for sayin all this. But if I was on a limited budget (like I am), even though I would like to get JL stuff, which i would, im going with a cheaper brand.
for SQ I like the infinity perfects. They have a MSRP of like 350 but can easily be found in a local stereo shop around 250 or less. If you look in the infinity show car they use JBL amplifiers. This is aprtially because JBL and Infinity are owned by the same company, but if you check out some online car audio forums, JBL amps are used what seems to me like more often than any other single brand. If you have a significant hunk of change to spend on all this then you can certainly get something of higher quality than a JBL amp but if you are ona limited budget they might be worth a look.
If you wanted a SPL woofer, which I dont think is the case since you are goign with a single 10w6v2, then I would suggest RF Power series (probably on par with a w6v2 for pricing) or a solobaric. The problem with JL, well, not a problem at all really, is just that they regulate who sells their gear a lot. So it is very unlikely that you will find a JL dealer who will cut you all kinds of deals based on your budget just to sell you equipment, whereas a local stereo shop will have the ability with Kicker/JBL/Inifnity/Audiobahn/RF etc... to move the price around to suit their needs. So basically I am gonna venture to say that you can shop around at 10 JL retailers and compare their prices to MSRP and then shop around at 10 (other brand) retailers and compare their prices to MSRP.
Again, if you are not on a limited budget then you can ignore this whole rant.
