kenwood kfc someing speakers of 4000, get panasonic or alpine headunit. ya koi b jis me equalizer acha ho. rear phata lagao lekan asa laga ho k vacum acha baney. dont go for sony etc speakers jo 3,4 hazr wale hain. coz bass etc achi nahi. 15000 for a head unit and speakers are more thn enough. i guess headunit and speakers 9,10 hazar me maximum mil janey. which gives enough good sound. remember combination is a key bro. doesn matter if you are getting the best combination with chinese or branded speakers or head unit.
