How does this look for a sound system ?
 

I have a 93 acura legend sedan. I recently had an alpine head unit installed. I am planning on putting polk audio MMC650 6.5s in the front doors, infinity kappa 692.51 in the back window and two IDMAX-D2 in the trunk. I am not yet sure what kind of amp to use to give these subs the full 1000wrms each, any ideas appreciated. I current have a 600wrms mono d amp I was thinking on bridging to the infinitys and the replacements for the stock tweeters, which I have been able to find or decide on what to get first. I want to set the subs up to hit around 135-140 db while not having a bad sound.I am going to dynamat the trunk and doors and roof.

Is this a good sytem design so far ? I have no ideas on what types of wiring are good. I know to run a little over 2600 watts rms I'm going to need to upgrade the altenater.

The IDMax's don't need 1000rms each and to be honest I would stay in the 600-750rms range per driver to keep them safe. They are very efficient.
