I see no reason for him to avoid JL stuff(it is very good stuff, reliable, and it will be fully authorized/warranteed which won't be the case if he orders it online). Also, many shops may not want to install stuff purchased elsewhere. If it fries, it can be a pain to determine who is at fault(if it is the equipment, why should they uninstall it for free to be shipped out, for example...it just gets into some gray area). However, paying $200 for rcas is insanity(especially when if he used cheaper RCAs, the $$$ saved could boost him from a 250/1 to a 500/1, for example).If they are a good shop, I would still go there for the install (over-priced or not). The install is very important. The shop should also be willing to install all the same gear even if you buy it from another store. I would suggest looking online.
I would also suggest avoiding JL stuff but if you want to get JL stuff... try this site (and there are even better like ebay)
the JL 250/1 amp - http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=11723
2 guage amp kit - http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=13336 (I bought a 4 guage kit off millionbuy.com for like $25)
RCA's (I bought mine at walmart for $20)
JL 300/4 - http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=11726
that there could save you a couple hundred dollars.... for some of the same gear. JL gear is over priced even on some sites. Ebay will have it cheap.
But that is good gear that you are getting. The subs are the lowest line but still good and especially for what you need. Don't get talked out of buying that stuff but shop around. I just did a quick 2 min. search that showed you could save some money.
I think that shop might feel that they have a guy who is just willing to pay whatever they charge. To the original poster: I would go back in and say that while you would love for them to do the install, you were hoping for a better deal. See if they will drop the price some. They might or might not. If you have money in your hand, they might be more likely to cut you a deal.
