This topic has been covered at least 10 different times on the forums , No idea why the admin or moderator hasn't made a sticky thread .
First off , for the $400.00 price on the (Upgraded) sound system it's worth it in some ways but not what you would think.
#1 The upgraded sound system is supposed to be the Alpine system, sadly its 100% TRASH .. ( Ask my garbage can )
#2 Only the front and read door speakers are alpine , but they have a Mopar / made in China stamp on them. - Very LAME speakers.
#3 Dash and all other speakers are trash as well ( Made in China )
I think it's worth it in a small way as the wiring is there so you can change all of the speakers like I did, Just don't plan on getting the 10 speaker Upgrade system and being happy. OH and even the 8" sub-woofer in the rear is trash.
Like I said , this topic has been covered so many times , I suggest the admins / moderators make a sticky of some old threads.
OH and Arsenal_man
, Infinity sadly will not fit in the doors :-( I tried . Also the upgraded system has a 300mhz cutoff so you wont get a boost of treble in the front. This upgraded system really is limited to say the least.
