install ideas

Well you are all over the map for quality of the brands you have chosen, from entry level (and out of business Jensen) to high end (Eclipse). If you want to do it right the first time, that's great, do it a step at a time. Just because your vehicle has x size hole does not mean that you need to put that size speaker in it. Sometimes the best of systems are a good mix of brands, best chosen to do the job you need them to. By the sounds of things you are not looking for something to blast you right out of the truck, but for a good balanced sound that plays to a good not loud volume level. If I was in your shoes I would have a look at a 5 channel amp, one made in the USA over the made in singakoratiawanachinapore variety, the US built pieces tend to sound a little better and have a higher current output. A 5 channel amp can save you some space and $ when it comes time to install and wire and a 5 channel amp, the proper one of course, can give a reallly good output level, probably more than you need. I would choose matching front and rear speakers, probably MB Quart, 6.5" components up front and a 5.25" coax for the rear. For a sub, a single 10" should round out the sound really nice, keep it to a sealed box for a solid output across a wide range of frequencies, there are a lot of subs made for small sealed boxes, the problem you may have is making it fit under the seat. Your best choice of equipment so far is the cd player, you will never look back when you purchase a cd player from Eclipse.
