I agree but asking a persons budget doesnt mean you are belittling the guys financial capacity lalo na if wala siya background about sa ICE. If you dump everything on his face when the guy just wants a basic upgrade he might think na wala na pagasa gumanda ang listening experience nya unless he spends more money. Any expert audiophiles kahit sa pdvd pag may newbie nag ask they will always reply with a question like, how big is the area? glass ba wall mo or may curtains ba? gaano ka taas ang ceiling? what type of music do you listen? how much budget are you willing to spend? They will not say immediately na you have to buy the b&w nautilus speakers dahil eto yung speaker na kahit saan mo ilagay na part ng bahay mo ay walang coloration ang sound nito.
Yes we have to lay it down but maybe the guy also needs some workaround on his budget. If the guy wants to get signal from his HU just tell him yes it can be done and it is possible, but if he wants more control then tell him upgrading his HU is another way. And upgrading one's HU doesnt mean he is free of noise, static etc. He has to spend again for good wires and rca. But this is just me and my 2 cents.
