What amp would be able to give enough power, say 200 watts when being read 8 ohms since wiring to parallel is not applicable? Side note: I still want to hook up two tweeters within the amp and control them within the DSP individually as well, bridging may not be applicable either.
How is wiring to 4 ohm not applicable?Aaron___ wrote:So currently I looking to put 2 8 ohm PA drivers in my front doors.

If that amp is a two channelGladiator wrote:PA drivers usually have very high sensitivity. Power isn't the main consideration since a little power can get these speakers very loud. Check the db per watt and at each double of power add 3db. That will tell you how much watts you need for the loudness you will get.
example if its rated at 96db at 1W
2W - 99db
4W - 102db
8W - 105db
16W- 108db
36W- 111db
72W- 114db
144W-117db
288W-120db
Most car amps are rated 4 ohm so you would have to look at the specs and divide the 4 ohm rated power by 2 to determine the power into 8 ohm.
An amp that's rated 300W x 2 @4 Ohms should be able to provide 150W to each speaker and produce levels at 117dB. That's pretty loud

At 4 ohm stereo it will only give around 75wrms
And typical two channel amp rating will be
75x2@4ohm
150x2@2ohm
300x1 @ 4ohm
