Yes....the Clarion will make a nice amp for your front stage once you have a more suitable amp for the subs so don't beat the crap out of it in the meantime......

And just for the record you should never load down one side of a 2 channel amp and leave the other channel empty....the unbalanced load will drive the P.S. crazy and generally shorten the life of the amp....

Alright, I was thinking of picking this up http://http://www2.visions.ca/Catalo...productId=3202
It's an alpine MRPM500 it runs 500W RMS at 2 ohms and is a monoblock, so if I ran the subs in series wouldn't this be optimal because the subs would be at their max power?

Almost.....run the subs in parallel, you will then have a net 2ohm load and the amp will then produce the optimal recommended power for your subs.

Nice combo BTW.....

To get more power could I just wire them in parallel to get 2ohms and connect them to the clarion and bridged the amp?

Probably not. The clarion will most likely need a min 4ohm load like every other 2 channel amp for bridged operation.

That would be the equivalent of wiring each channel to 1ohm.

Ohh ok all good, I'll most likely just buy a new one. Do you think it would be In my best interest to buy an alpine MRPM1000 instead and run them at 4 ohms which would be 500W RMS and then if I upgrade my subs later (to say W3's) I could run them at 1000W RMS?

$$$$$$$. If money's no object then I thinks most will tell you that the biggest amp is best. If it were a powerful amp you would just keep the gains turned down. But how are you going to wire 2 4ohm subs to 4ohm overall impedance??

If you've got the money, sure get the 1000W, run your subs in parallel and keep the gain turned down. I've found that when it's time to upgrade you'll probably want something different than what you have in mind now.

If the voltage increases by about 15% (from 12.5V to 14.4V) and ohm's/Joule's law says that if you double the voltage you will quadruple the power (P = Vsq'd/R). Therefore at 14.4V the RMS rating should be about 663 Watts. 800 Watts of dynamic power at 14.4V would seem to indicate the peak power, and now we might have more of a glimpse into the amplifiers capabilities, RMS (safely, all day long) output of +-663W and a peak output (maybe only safe in short busts) of 800W when connected to 14.4V.

After a quick bit of hunting around last night I found more info siding with dynamic being equal to peak than the other. And it made me second guess my initial thoughts. I think the OP is more correct to relate dynamic power with peak power.
What you say makes sense on a general basis but one of things I like about MTX is the fact that the 'dynamic' power rating is given with the THD value, unlike a 'peak' rating. An MTX will be as clean a signal at that higher value as the RMS rating, which IMHO gives a better idea of what to expect from the amp in day to day usage.....
