6x9s will get you a balanced sound, with just slightly more treble. I have 2 3-way 6x9s in their own boxes behind my seats, and before I added more speakers my mirrors still shook, and when turned up enough you could feel the whole floorboard, seat, and gas pedal vibrate underneath you. Not much, but you could. That's with about 18 watts RMS going to each 6x9, sealed boxes, custom made


The boxes are about 7 inches wide and 10 long, tops. I cannabilized the support speakers from a home theatre system to put the 6x9s in.

here's the 6x9s with guards behind the seat (reg cab)


The box I cut apart for the 6x9s: (Had to use a coping saw to make the hole the right size. I have not even half an inch of wood left on all 4 sides of the top piece of the box)


the 6x9 in box. The metal mount area hangs over a little, the guards a lot as you can see. But they sound pretty good

You would need an amp for the 10s. That being said, since it is a "junker" 6x9 should do it for you. There are alot of places that could fit that size speaker just be creative!

Thanks for the post man, looks like i'll be going behind the seat.

No problemo, have fun with your new system!

how much bass, more how they're constructed. A lot of car-type speakers incorporate a crossover and more than one speaker suspended over one another, if the door speakers are like that, you should get a better range.

Again, this forum rocks, because I've been wanting to replace my door speakers at least, since they are I guess blown or the cones are detached, because they don't sound good at all.

A reasonable factory system would be enough for me (mine actually has cassette/radio only) - I have a Griffen iPod adapter - but this one's really not performing.

Behind the seat's a great idea, I was going to suggest underneath, but that's much better - although if they were subs, that'd give you bass you could feel!
What's the best replacement for the door speakers? What size? If I get ones off a wreck I assume they'll be just as bad.

6.5 inch door speaker. I have 6.5 inch 2-ways, but I hear component speakers give a better sound, more clear. But you have to make a new hole in the door panel to put the tweeter in.

The other day somebody was asking what the vent at the bottom rear of the door was, if you wanted to stay totally stock-looking, you could put one of them there - although I guess that's not the place for a tweeter.

Believe it or not, you may not need another pair of speakers. You can expect at least decent mid-bass out of almost any aftermarket speaker if it's installed correctly. You just need to deaden your door and seal it off a bit so you isolate the front wave from the back wave. I did this with a set of 5.25" coaxials, and it already sounds like it has a small sub. That being said, if you need any real bass, strongly consider a subwoofer, you will never get much lower than about 50 to 60 Hz with a typical 6.5" or 6x9" car speaker.

If you want more info on how to seal off the door and deaden it, just let me know.

I thought about putting a speaker down there, but I felt it'd be too much work to go there
