timreams as far as if i am going for BOOM or SQ i want something in between. and my HU is the pioneer DEH 5300UB

so basically i am debating between 1 15 or 2 12's.
There are a lot of things there that need to be considered. First of all, a speakers rms value is just what the speaker is rated for. Doesn't mean you have I meet that value. So no, you don't have to get anywhere near 1kw. I personally run two 12s with about 600 rms And am more than happy. That being said, I'll also Adress the sensitive thing. Sensitivity of a speaker is just one more measure of how we look at a speakers ability to reproduce sound. You will find that as power handling goes up usually sensitivity goes down because the voice coil is larger. And as for the difference between 90 and 85, it would be hardly noticeable. Anyway, I would do the two 12s. More sound, tighter bass, less power required.
