The head unit is just for looks. the dayton DSP is your head unit. its going to make the biggest difference with a 4 channel if you actually read my long comment properly. Its literally how proper sound quality systems are made and designed. Its more advanced some some cookie cutter mediocre tune and install stuff.
You also dont just match rms with the speaker, you always have way more than needed to prevent any chance of distortion or clipping. An amp barely lifting a finger to power your stuff vs an amp that is redlined. Which one do you think provides cleaner sound? which runs cooler and lasts longer? Again dont cheap out on power. 4 gauge power and ground and that pioneer and the dayton dsp.
The infinity amp's bluetooth is gimmicky and junky. Looking into it is bluetooth 3.0 several generations behind we are at bluetooth 5.0 and aptx/aptx HD so its a lossy as fk audio transmission format. The amp also utilizes artifictial boosts in the clari-fi feature while giving you ZERO tuning functions absolutely zero. The dont even list what dac is used so its a crapshoot, judging from the price its not a high end one. so its just a waste of time and the results you get is either mediocre or below mediocre, being two channel means you have to use the passive crossover on the morels and thats just like playing the lottery either the passive crossover works with your car or it doesn't and when it doesn't you'll be playing the "lets swap out speakers like underwear" game and waste a sh*t ton of money getting sh*t results and blaming it all on the speaker's fault when its just a system design issue.
The dayton DSP has audiophile grade internals with top of the line APTX bluetooth technology. Dayton is well regarded in high quality audio community more than infinity which is just popular among mainstream joe blows. While the pioneer amp is amp dyno tested and proven as well to make more power than rated.
