Hey guys I'm fairly knowledgeable in some care audio. I need help some information regarding my cars (2004 Acura MDX) i believe it hold 150amps system that i installed myself. I have 4 Guage power wire about 17 ft to the distribution blocks. From there i have one RF r500-1d powering two 10’s at 2 ohms and one RF p450.4 powering one 2 10 chuchero speaker box. If i replace the R500-1d with a R1200-1d if it’ll be too much for my cars alternator and or the power wire? I would keep the 2 10’s which are wired at 2ohm and the r1200-1d runs at around 800 watts rms @ 2 ohms. Thank you all!!
