I've been through two GTA car kits and the main issue seems to be the output is overdriven, which results in crackling audio caused by clipping. Does anyone have any recommendations? I'm looking at both the Vais and DICE solutions.
If you don't have JBL, you may want to consider swapping out the entire radio to an aftermarket setup. You can get a radio with Bluetooth, HD Radio, USB etc for around $150 with installation adaptor and wiring harness. Way more features than DICE will give you.
