Okay i need some advise on how to setup my system so my speakers can produce to there full potential I have 6 speakers and two amplifiers i would like to use all 6 speakers and the two amps, my head unit is a jvc. The front door 2 rockford fosgate power speakers 75 watts rms each The rear door 2 mtx speakers middle of the range roghly 60 rms The back of car under window 2 kenwood 7x10s 90 watts rms each Amps 1, Rockford fosgate punch p450.4 4 chanell specs 60x4 watts @ 4 ohm 110x4 watts @ 2 ohm 225x2 @ 4 ohm brigged 2, Sony xplod 2 channel 250 watts 100 Watts RMS @ 4 Ohms I am thinking the best way to set this up would be two run the front fosgate speakers and the far back kenwood spekers of the rokford fosgate amp. I think it woul be best run at 110x4 at 2 ohm so each speaker recives 11o wats thats 440 watts. The four spekers at there max would be 75x2 for front and 90x2 for far back so this would be 150 + 180 so 330. And then run the sony Xplod at 4 ohm with the two mtx xpeakers in the back doors giving them roughly 50 wats rms each. My head unit has thre preouts and is a good quality jvc head unit I am going ot get this system insatlled in a few weeks. Any feed back ideas or changes to my setup or theory would be great, as much feedback as possible would be much apreciated, i would like to get this right thankyou
