i am looking for a set of good quality compnent speakers for my 2013 gmc sierra regular cab truck. i have a set of mb quarts that i bought back in april which are now made by maxxsonics and are terrible (what i get for not researching). looking to spend up to 400.00 and they will be driven by an older fosgate 555x amp which is a 70 X 4 amp. i will be putting a jl audio steathbox with a single 12" sub in it later. since researching some i have found a bunch of brands that i've never heard of before and just want some advise on what people have had good luck with. i have read some about morel tempos, focals, diamonds, massive audio, image dynamics and cdt. jl audio c5 -650's are german made that i was considering but there are plenty of others i see too. i want to avoid chineese made sets, thats all. thanks in advance, paul c.
