First, some info. I have a 2005 Altima with Bose. I have replaced the HU with an Alpine 9831 that I had in my old car. I also have a C400.4 in my closet. I am having a hard time decided what speakers to get. I really shouldn't spend too much as I need to get myself a house this fall and need to save up some money (but I love my toys so much!). I am only looking for a pair up front, all other speakers will just not be used. I may add a sub later, but I play paintball and I need all of my trunk space for gear.
Option 1) DB6500's. If I go this route, what else do I need to ensure they sound good? Baffle? Damping on the door (not going full car, at least not now). Only speakers that polk/crutchfield says fits up front (component sets) I'm really worried about the tweeters being way to harsh as some say they are. That would be cause to put the bose back in for me. But I think I should be able to adjust my amp/HU to take care of any of that.
Option 2) MMC6500's I really worried these won't fit. They seem to have huge baskets and Crutchfield and polk say they don't fit up front. It also seems that the mounting holes won't line up and I'll need an adapter which I can use as a spacer if needed. It would be nice to know why they don't fit according to crutchfield/polk so I can see if I can make em fit with minimal work (ie, they need 1/4" spacer, or you need to cut the door panel). Also, do I need baffle and/or damping. How much sound quality would I lose if I mounted them in the rear deck and none up front? Polk/Crutchfield say they fit back there.
Option 3) SR 6500's. High cost, but everyone seems to love em. Same problem with the MMC6500's, everyone says they don't fit (or they don't list them as fitting but they seem to be smaller than the MMC6500's so maybe they do. Do I need baffle and/or damping to make em worth it?
When I ask about baffle/damping. I know they will sound better (not sure about baffles though) but I'm asking more of is it worth getting if I'm not going to use damping at all due to cost. Also, if I set them up as coaxials will they degrade enough to warrent just getting the coaxial models and saving on the cost of the speakers? I have airbags in my A-pillers so I'm nervious about mounting tweeters there and don't want holes in my door panels.
Also, how hard is it to mount tweeters in the A-piller, I hear I need to fabricate a mounting bracket.
I have installed amps/speakers in my previous car so I know I can handle it, its just that this car is pretty new unlike my old car.
I really don't have a budget, so all 3 are options, but I may decide to go DB's for ease of install and put more money away for my house. This could be the most expensive install ever! I need to buy a house for the garage space to install them in!
