Went to two places, Car Toys and Magnolia Audio Video. As you may be able to guess by the websites, Magnolia is a pretty high end store, and is actually the place I bought my first pair of speakers and reciever. Anyways at Car Toys The guy recomended getting a 4-channel amp, which would fit in the back storage compartment of the car (small-ish space build into rear corner), power the front seperates with that, the subs by bridging the other two outputs, and the rear coax speakers just off the deck. For subs, he showed me some JL 10"s in a generic sealed box. I listened to some Focal speakers there, and liked them a lot, much better than the Alpine or Infinity componants they had. Then I went off to Magnolia, who sell much better gear. There I listened to some Boston Acoustics and Diamond speakers. I thought the Bostons were much better. He recomended both Alpine and Kenwood decks, and agreed with Car Toys on putting a 4-channel in the back storage box, and two 10"s in the back. Unlike Car Toys, this place builds all it's boxes when it installs, and I totally support a custom box, because I know the importance of a good enclosure. They also replace all stock wiring. So in addition to the 6 1/2" componants up front, I plan on replacing the 5 1/4" coax speakers in the back doors, you know, to give the other people in the car some love too. So here is what I'm looking at right now: Alpine CDA-9851 I am flexable on the deck really, I just want something with good quality, a decent amount of power for the rear speakers, something that is not full of stupid blinking lights and ugly animations, and has a AUX input. Boston Acoustic Pro60 So these are $600, but I found them on ebay for $350... I could not directly compare them to the Focal speakers, as they were at different stores, but I really liked them, and they blew away the cheaper Bostons and the Diamond speakers. Boston Acoustic SX55 The only perfect match fo the front speakers would be to get another $500 or whatever 5 1/4" componants which does not really make sense, so these will do fine. Alpine MRV-F345 75 watts RMS x 4, again, two for the front seperates and two bridged or whatever for the subwoofers. Fits perfectly into the storage compartment, allowing me to use only one amp, and to have it hidden. Seems like the pefrect solution to me. Kenwood eXcelon KFC-XW1002DVC I am flexable on the subs as well, but this is the 10" they had in store and was recomended to me for the power it they will be getting. Custom Built Dual 10" Box, NOT shown here: So I know I want dual 10"s in a sealed box, I talked to the install guy who thought a downfiring box would be good. Also hides and protects the woofers a bit. Yah yah, I could make my own box, I know this... On top of this gear, I need to pay for all the wires and extra parts which is up to $200 or something like that. So that is what I'm looking at. I will probably get a bunch of the parts online as I can save so much money, it is still pretty flexable what I buy, but that looks like a very good system to me and I am excited to replace the stock POS.
