I know its not that good idea, but it will be temporary till I get enough budget. I have pioneer cd player & I wana connect it to bose oem speakers & amplifiers. what is the suitable way for connection? is there any write up about this subject?

Check out sonic electronix they have amps and subs "open box/unused" cheep as hell they got good deals on every thing. they even give you all needed harness/mounts/connectors with every thing they sell.

or check out "sound eco" in Doha, Qatar. every thing is cheep over there, or m9f7 garages in UAE. They will get you every thing they might charge you around 500-1500 dirhams for every thing. They will even install it for free. I did full sound system on the OEM screen in "sound eco" in doha for my E46 330ci BMW. They did a good job.
If you need any thing over there PM so I can get you a good deal over there.
