I just installed a pair of Punch 6x9s in the rear deck and am going to put another pair of Punch 6x9s in the front doors. Should i get a 2 channel and run left right in parallel or get a 4 channel? I assume that if i run in parallel i will be creating a 1 ohm load ( speakers are 4 ohm). I am leaning towards the 4 channel. Each speaker is 75 w RMS. If I go 2 channel i will get 150 w RMS x 2 for 300 w total. If I go 4 channel I will go 75 w x 4 @ 4 ohms Since I run my sub amp at 2 ohms I was thinking the 4 ohm load will create less stress on my electric system.
Just curious, why 6x9s in the front doors? Thats a big speaker for a door IMO. Will it fit without interfering with the window? I feel that 6x9s are strictly a deck speaker, but I'm sure others may disagree. I'd go with the four channel at 4 ohms if it were my car.
Another vote for a 4-Channel. Actually, a 6 x 9 would make a great front speaker. Think about it, its big, lots of surface area. This means we would have decent bass and mid bass up front. Major PLUS. The only real down side is the size, in most cars, you can't mount a 6 x 9 without major mods, but if you can do it.
Thanks. I will go 4 channel. The stock speaker in the door is a 6 x 9 so I wanted to keep the same size. 2007 Camry.
Actually, no. Two 4-Ohms in parallel gives 2 Ohms. 2-Channel option: Possibly cheaper while maintaining the same power. Let's say your target is 100 watts per speaker: You can get a 100x4 amp or possibly save by getting a 100x2 amp that can produce 200x2 @ 2 Ohms (still 100 per speaker). 4-channel option: The amp will run cooler and produce less distortion with a better damping factor. You can also fade the sound front-to-back, something you won't be able to do with the 2-channel option.
