the HU will be under a bit more stress being required to pump out more current than expected... I'd guess it'll be ok unless you have it cranked for long periods. Personally I'd just find a budget amplifier...
either one of these tweeters:

You could probably cut your budget nearly in half and still come up with a system you would be very happy with. No need to throw money away.
Strong front midbass is overrated. It's one of the least important parts of this entire build, imo. Not where my money would go. Sure it is nice, but it...
Taramps HD 3000 seems like everybody's go to for small footprint & low cost. Even though it can produce far more wattage than I would need. (at the moment)
Any other recommendations? It would be nice to be closer to the 1200-1500w @ 1ohm range for $100~ or so. I'm comfortable spending the extra...

You wont have to worry...
