A couple of people in the business have advised me to keep my front speakers and LOSE my back speakers. The obvious reason is that your ears face the front. I have just acquired a top notch sub (10" Boston - in sealed box), and thus I am told there is no reason to want bass from my 6x9 speakers in the back. This is understandable of course, but surely I want to keep the high frequencies and midrange in the back, spreading around the car. The car is a honda civic hatchback (96). The speakers I have in the front are old Pioneer full range 16cm, which are a bit tired now. I will be upgrading to some decent components eventually. But even so, I have the power there (4 channel pioneer amp), so why not use it for the back too?? So, my 2 options are: 1. Get a shelf made for my Infinity 6x9s, and upgrade to decent front components. 2. Do away with the back speakers completely, and upgrade to front components. Another reason I am advised to remove back speakers is that they may spoil the quality bass from the sub. Can any of you guys share your thoughts on this and recommend anything? This would be great.
