If I have two component speakers with 4 ohms impedance each and two coaxials speakers also at 4 ohm impedance. What type of amp do I need so that each speaker gets 100+ watts. I know I need a four channel but I do not understand why amps post ratings at 2 ohms and 4ohms. Why are posted RMS watts higher at 4 ohms. Please help with some options. Thanks in advance.
Hey Paul, they list power at 2 and 4 ohms so that depending on your speaker configuration, you can either go with 2 ohm or 4 ohm setting. Since your speakers are 4 ohms, get a 4 channel amp that'll give you maximum power at that ohms. I personally bought Audiobahn 2000W 4 channel amp. I looked at other brands but I wanted one that can operate as a sub amp and a full range amp. If money is a problem for you, try MA audio. They also make 4 channel at a reasonable price. You'll never know how good a sound could get till you by pass the headunit's amp!
The model that I liked was HK597. It is 200W rms per channel at 4 ohms and 400W per channel at 2 ohms. I was going to buy this amp but decided to go with Audiobahn A4125HCT 4 channel amp, only cause it came with a bass remote control. MA audio amp has much more power though as you can see. If power is what you want at a resonable price, try MA. If you want maximum power for driving subs, then try Audiobahn, it is 1000W rms x 2 at 1 ohms! If I had more cash, I would've bought MA audio also and use it for powering front and rear, use Audiobahn to drive my sub.
When you say Audiobahn and MA are trash, what model are you talking about? I know they make cheap amps as well as some higher quality. Have you had experience with Audiobahn A4125HCT and MA Audio HK597? I don't know about you but those 2 models are good amps, at least to me. Maybe you had some bad experiences with their cheaper models.
