You can buy speakers that are two-ways. That way you wont need to mount tweeters any where. Also getting a speaker harness would save alot of time during application. Its not a long process. Very easy actually. Also, I would suggest buying new speakers over used ones. If you want more bass out of the speakers Alpine will suffice. Although they are not good on clarity. In my opinion, the best way to judge what set of speakers you want is to go down to audio shops. Each one may have a brand that another did not have. So you gotta compare. When you get there, turn up one of the radios thats for demo and listen to each set of speakers on display. Or even bring in a fav cd to put in. Some speakers sound better for different types of music. Make sure that the store has the amp and/or subs turned off as well when you are demoing them. You'd be surprised how an amp can change the sound. No one can really tell you what is better...You need to be the judge because its your ears that are listening to your system every day. Hope this helps in your decision process.
