Bought
Fusion 8Awg Wiring kit from eBay.in but the product wasnt that great,they says its 8awg, wire thickness is not more than 2mm. only insulation is thick. So got another power wire and ground wire from olx which is thick and guess its 8awg, No brand though.
Fixed the amp, Wired it, Sorry couldn't take pics as i was alone doing all this. Initially i was shocked,no vovals from the speakers. Pre Out was set for subwoofer and i had to check the HU's manual how to set it for rear speakers and done. The speakers sounds very good now,but TBH, i am not at all satisfied with the bass, may be because of the tray am not getting deep bass, i think its not doing anything under like 55Hz. Dont know.
Anyway am not going to add a subwoofer now. out of budget.
