Due to some unforeseen circumstances (dealing with a disreputable online retailer) it appears like I will shortly be in possession of 2 amps instead of one. I had just wanted a 2 channel amp to power my Phoenix Gold RSD65cs components and then I was going to determine whether or not to add rear fill or a sub with another amp down the road. But now, I have an MB Quart DSC280 (80x2 at 4ohm) and a Planet Audio RX4.400 (100x4 at 4ohm) to be delivered this week. My wife is less than impressed with this turn of events and says I can only keep one and will have to sell the other. My first question is, assuming I follow orders, which amp do I keep. I'm pretty sure the MB Quart is a better amp in terms of quality but at the same time the Planet Audio gives me the easy expandability for rear fill/sub in the future and more power (I do like rear fill fyi, I know from what I've read most are against it, but my head feels out of balance without a bit of sound from the back). My second question, if I keep both, will my 1996 Ford Taurus V6 be able to power both without any modifications to the electrical system? Can I use a distribution block with these two amps or would I need to do some upgrades as well? About: I'm very new to car audio, this will be my first amp, I want SQ and I'm a moderate audiophile but I'm quite content with an okay/decent system at this stage of my new addiction. I'm leaning towards the Planet Audio because I know the retailer I bought it from is reputable and will honor the warranty and be there if I have any issues. The other one, well, let's just say if I actually get bricks in a box instead of an amp I won't be too surprised. Thanks.
