Thanks for the extensive explaination. I would consider changing my door speakers if it was going to give me a Bette quality and crisper sounding system. Do you recommend any particular door speakers for the truck?
Back to adding two subss instead of one. I don't want to rattle the teeth out of my head so do you think adding 2x. 10" subs would over do it? I'm not a 16 year old kid hooking up a sound system in my shitbox irock anymore lol!
i can't really recommend any speakers because i haven't done mine. as i always say...can't go wrong with JL or Alpine.
2 10"s won't be brain rattling but it will be loud. loud enough that if turned up to 1/2 volume you will be able to hear the thumping from well outside the vehicle. inside the truck your hair will move a bit and the change in your center console will rattle.
but like i said, you can't fit monstrous 10"s (or 12"s) that will be too loud like you're thinking. go with 2 10"s... in the 600W RMS(total) range. if it's too loud just turn the amp down, that's all! that way you can leave it civilized or if you want to turn it up you will have the power there if you need it.
if you find that you're happy with it turned down from its max then you'll probably be fine with the stock speakers. if you want more bass, turn it up then decide at that point if you want/need new door speakers. that's what i would do.
