I have been trying to research different receivers and amplifiers so I can build my own home stereo system, I want to use a pair of Q-POWER subs that are brand new. They are 600 RMS @4 ohms. This is a DIY project and I am completely lost. Can someone please offer some advice on what receiver and amplifier I should be looking at. I have to keep this on a budget, but not cheap. If you can understand my situation?? Thank you for any information you can provide. -Daniel..
