I have a chance at getting these dirt cheap...right now I have a kenwood mp3 deck in my car (good deck) but nothing else. would the kenwood 8101 be good for one of those subs...and the 5201 or the other small amp for the speakers? And in general what do you guys thinks of these products and which ones would you go for as a small setup. I'm not looking for anything too out of this world...just to touch up my current lacking sound. I just bought some nice infinity speakers for my room and noticed what I was missing. ANyways I have a 94 mazda 626 cronos lx. Stock speakers are decent but nothing fancy. thanks
