I have 4 Infinity Kappa Perfect 6.1s one in each door rated at 100rms(400peak) and 2 Infinity 693.11i 6x9s rated at 110rms(330peak) per speaker. I want to try and run all six speakers off my Infinity Kappa Four amp rated at 125rms x 4 @ 4ohms, 150rms x 4 @ 2ohms, 300rms x 2 @ 4ohms bridged with an overall rating of 600rms and 1200w peak. My idea is to run all 4 Infinity Kappa Perfects in a series/parallel circuit to the front channels keeping the impedance at 4 ohms bridged at 300rms x 2 @ 4ohms giving each speaker approximately 75rms then running the Infinity Kappa 693.11i off the rear channel for 150rms x 2 @ 2ohms as the 6x9s are rated at 2 ohms. Would 75rms to each speaker be enough for the Infinity Kappa Perfect 6.1s without under powering then enough to cause damage? Currently I have 2 Infinity Kappa Perfect 6.1s on the front channels and 2 Infinity Kappa Perfect 6.1s on the rear channels giving each speaker 125rms. So my final question would be is it safe to run these 6 speakers off my Infinity Kappa Four or should I get another amp and run the 6x9s with a sub woofer instead? Any advice is appreciated, thank you.
