As far as your system goes, if your focus is SQ, it may prove to you to be as hard to find as the Holy Grail. If you haven't purchased anything yet, what is your budget?
There are lots of good name brands & bad ones... but the main difference is the cost of having to pay more for a certain name brand among the good ones. I have friends dumping tons of money on audio gear because they think the more they spend the better. Just know that it isn't nessesarily so...
What do you have available locally? Or are you buying online? Are you open to RAW DIY drivers (by far the best value in speaker selection, and there is more info about what you're buying available, unlike Car Audio brands)
Finally, I would make your speaker selection carefully since this will make or break the tonality of your system.
Thanx guys for overwhelming response.
My budget for cabling [includes 4G power kit for amp,rca cables for 5-ch amp and 66 mt spk wire for 4 door spk abd one subw] is aroubd $100.Obviusly if i can find a better kit with lower prices i will go for it.
Locally we have here JBL power kit for $55 and audison [all i need] for $124.
I am getting Monster power kit for $40 from onlinecarstereo,monster 16G spk wire 100' spool from and 3 rca cables each 16' long for $40 from hookedontronics.
I checked knukonceptz wires and they seem to be cheaper than monster.not sure about quality though.
My total budget is $800.
