OK newbie here, first post. Joined a few months ago when I had a 95 mustang gt, that got wrecked by an idiot who ran a red light. Bought a silverado. Love the silverado but I want something more muscle car for a daily driver and use the silverado to tow my boat. I was originally going with a 2010 camaro ss. But after three attempts to get an order in, all failed, I decided gm didnt want my money and to come back to ford. I love the new style, love the new interior and it looks sooooo much better than the camaro its not even funny, and they are sitting on dealer lots waiting to be sold. Add in the fact that ford is a secure company it just makes so much sense to get a mustang. Looking at a gt premium with a manual. But not sure whether to get the shaker 1000 or the GPS. I wish I could get both. both have their advantages and disadvantages. shaker 1000 more power better system best avail con. none of the cool GPS feature no screen on the dash looks bad IMO GPS all the cool features the new system has the cool screen con only the 500 system is avail. So I ask you guys. Is there a huge difference in sound quality between the 500 and 1000. I love bass and dont want to mess with aftermarket in a system this complicated. I have an awesome system in my silverado with 1000w amp on subs and then 4 channel amped component speakers. But does the 500 go just as loud with a little less bass?? thanks a bunch guys.
