Wiring up tweeters into the dash shouldn't be a problem at all. My crossover is located under the drivers seat, and the head unit powers everything. 4X45 watts. Unfortunetly, I've no idea how exactly the wiring was done. I chose how what I wanted, and commissioned to have the work done. But tweeters in the dash with the treble turned up high enough can become powerful enough to be painful to the ears. The high notes will go up, bounce off the windshield, and flood the compartment with sound. It sounds great when playing music with both low base, and high notes like classical music, and electronica. For the kickpanels speakers, I'd reccomend to go with straight component speakers. You won't need multiple channels if the tweeters above are hitting the high notes. Let them use all their power to pump out midrange. The same goes for the speakers that you put onto/into the back panel. Let them do the midrange work as well. Now for the stock speakers in the rear, I'd reccomend a set of 2-channel ovals. That way you'll be sure to also get a nice mice of things from in the rear. The biggest concern here is surface area. You're best best is either sticking with the stock 4x10", or perhaps 4x6". But you want to make sure that you use whichever one has the most surface area. Which one does, I've no idea. You'd have to do the math on that one. If you don't install subwoofers, then change the rear component speakers over to 2 or 3-channels. Otherwise, leave them be. The "traditional" installation method has been to install the woofers into a custom box on the rear parcel shelf. This is ok, but what then is the point of having the parcel shelf then? So in turn, this isn't my favorite method. That and I perfer to have everything as hidden/stock looking as possible. Under the dash there might be room to install a 6 1/2" bazooka tube on each side. The problem here though is that they'll just 'fire' the sound waves into the sides of the car, depending upon the length that you choose. Otherwise it may be worth your time to install custom ported boxes with 2 speakers on each side so that they are directed twards the floorboard. Slap the floorbards with your open palm, and they'll sound just like a drum. Since these panels resonate so well, they'll also contribute to road noise. My advice is to install nose noise deadening material that you can also remove easily. That way fore regular driving, the ride will be comfortable, but you can pull it out for times when you want to cruise around and show off the system. Another option that I'm looking at doing myself, albeit a radical one, is to possibly install divders in the rear pontoons (ahead of the antenna & air intake), and install woofers with foam baffles behind to protect them from the elements. That way I could just use the entire rear pontoons as bandpass boxes and not worry about having to sound proofing them. Or perhaps depending upon how it sounds with a test speaker, doing something simular with the front pontoons either/or. I hope this not only helps you a bit, but also gives you a few ideas for future projects as well! -Robert vin 6585 "X" --- In dmcnews@xxxxxxxxxxxxxxx, Soma576@xxxx wrote: > Robert, Martin, etc. - > > maybe what i need is suggestions on what i should be doing. replacing the > rear speakers in their stock location with something acoustically better, or > building something into the rear wall.
