Team, Finally I have it as well....The BLAUPUNKT THA 555 PnP + Linea Adaptor + 5.5 m Wiring harness. And that is all the upgrade I have done for now in my PHASE 1 of iceing.. The Setup: AMP in the boot fixed on the rear of back seat with 5.5 m extension cable. Looks really neat. I went ahead with the boot idea as its a class D amp and as we would be using its 5 channels with no bridging and stuff involved, the heating problem should not arise. Its PHASE 1 (budget constrainst :A ) ...so hooked up to stock speakers as of now with appropriate tuning so as not to fry the speakers. The amp is being powered by the HU with the yellow cable which is the best option till you add a sub to the scene. Amp powers on and off with the HU. No manipulations required inside the Fuse box whatsoever. Red cable is for continuous supply (maybe required if you want to use the direct input feature). I hope that wire (some 12 gauge i think) works fine when the sub is added later. This can be bought only because its a class D and known to utilize less power. I sound is neat and crisp than before and the volume can be upped to 25 without distortion. Had to go for Phase wise iceing as i was out of buck for a full upgrade and dint want the dealer to sell off the rarely available amps to anyone else. I enquired casually and he arranged it for me within a week so had to go for it, even though no improvement in qulaity was expected as yet. PHASE 2....I am on the lookout for some more information on how to provide ideal power to the amp so it performs to the brim without malfunctions. Also checking for amp speaker wattage combination (read somewhere that amp should have more wattage than speakers for better output without distortion, hard to believe though). Another query that i need sorted is whether 2 ohm speaker is a more viable option as there would not be any channel bridging involved...(less impedence means more output from lesser power) and 2ohm output is higher per channel.
