OK, this setup may be a little weird, but I'm waist deep into it and don't really want to start over completely, so hoping someone can help me out with some good advice.
This is on a houseboat.
I have a basic car stereo (fairly new JBL), a pretty old Xtant 404 amp (50 watts x 4), hooked to four speakers which I *THINK* are good speakers (Definitive Technology AW6500's),.
They actually do sound quite good, just not nearly enough POWER!
The speakers are fairly new, I bought them b/c they are outdoor speakers (yes, sometimes it rains at the lake!), I have a little over $1,000 in these 4 speakers, so I really don't want to start over with new speakers if I can avoid it!!
So the specs on the Def Tech speakers (per the owner's manual):
As I've learned a little about all this, I see that the 8 ohm speakers are a little problem since car amps are designed for 4 ohm speakers (right?).
SO... I called Crutchfield, they guy suggested a Rockford Fosgate Power T1000-4AD amp, which is 250 watts RMS x 4 at 1 to 4 ohms.
When you double the ohm load the watts are halved, right? So if the amp says 250 watts at 4 ohms, my 8 ohm speakers would only pull about 125 watts per channel, is that correct?
If I hook these 8 ohm Def Techs (which are rated only 200w peak) to it, does that sound like a good setup??? Looks like to me it should be SAFE at least (amp says 250 watts, but speakers should not pull over the 200 watts peak rating since they are 8 ohms, right?)... but I almost think that isn't enough power. If I'm going to do this, I want to do it right the first time, and be ROCKIN' at the lake!
Could I throw MORE power at the Def Tech speakers?
Also, I have read a bit about the Class D amps, and several friends who are into this much more than me have said class D is the way to go... this Rockford Fosgate amp is the new technology Class AD (NOT AB)... so, is it all that? Is this a good amp?
The ultimate goal here is to feed as much power to these Def Tech AW6500 speakers as they can handle without blowing anything up in the process!
Any thoughts or suggestions are greatly appreciated!

- nominal impedance 4 - 8 ohms (I didn't know what impedance was when I bought them (and barely know now!)) :-O
- peak power 200 watts (manual says "Rec. Assoc. Amplification 10 - 200 watts")
