On your question to the speakers...i have no answers sorry...but for your remote start issue...if you kept your head unite which i hope you did because i redid my whole system and if you dont keep it, it will throw codes and will make it so you can't see your little display computer there is a hook up for that, i have it running out in the trunk of my car, also i would have to say go with JL Audio TR's they are great speakers i have and i ran an amp(300/4) to them, also i have a 10' JL w7 with a 500watt sub running to that both amps JL audio...everyone that has heard it says by far one of the loudest single subs and cleanest systems. but thats just my 2 sense on the starter...
