[QUOTE="PeerlessAudio, post: 6975400, member: 625579"] I would recommend getting 2 amplifiers. For your subs, look for an amplifier that matches the combined power rating of your subs at 4 OHMS, not 2 ohm or 1. A lot of companies rate their amplifiers "max power" at an abnormally high voltage input level and an abnormally low impedance. (Impedance referring to 4 ohm, 2 ohm ,etc...) If both of your subs are dual 4 ohm coils, you want to wire each subs voice coils in series (positive connected to negative, positive connected to negative). This will essentially make each one of your subs present an 8 ohm impedance. Now wire both subs together in parallel (positive connected to positive, negative connected to negative. This will present a final impedance of 4 ohms to your amplifier. I would use a mono, preferably class D subwoofer amplifier. Now as for your speakers, you are dealing with 6 speakers which all have varying power requirements. You could use a 6 channel amp, but they are a little hard to come by, and are usually expensive. Plus you have power requirements ranging from 35 watts to 150 watts. If you use a 6 channel amp, chances are you are either going to have some seriously underpowered or dangerously overpowered speakers. Your best bet would be to not use the 35 watt door speakers at all, and get yourself a 4 channel amp that puts out 125-150 watts per channel at 4 ohms. Door speakers are usually poorly located for quality sound and imaging anyways. Hope this helps. [/QUOTE]
