Got the shaker 500 system in my 07 gt was wondering if putting new speakers in would make a difference in sound or is it not worth it .. Gonna keep the stock radio in..

 

I dont think putting just new speakers would make a difference in sound. If you were replacing the entire sound system, thats when you would probably see results. But the stock speakers and subs sound really good with the stock amp... the reason why new speakers may not make a difference is because the new speakers may not be a good combination with the stock amp and receiver already in the car...

 

I've replaced the stock speakers with polks and it makes a HUGE difference.

 

It will make a big difference but a full sound system will make an even bigger difference.
I put some infinity 6x9s in my accord and loved them without an amp. I have some pioneer ts-d6802r speakers which are designed to fit fords 6x8s but i cant tell you how they sound just yet, im waiting to buy an amp and do it the right way.

 

changing just the speakers can and will make a difference on the shaker 500/1000.....big difference from the paper filmsy crap they use from the factory

 

yep, changing speakers, especially when the oem 'audiophiles' are of paper construction (). a higher quality speaker will sound a lot better with no matter what audio source you are using... usually

 

better speakers will always sound better, up to a point, if you have problems with your amp/head unit it does not matter how good of speakers you have it will still sound bad, but if youre head unit/stock amps are in good working order and you dont go too crazy on the speakers (i.e. dont run 2ohm speakers if your amp wants 4 or 8 ohm speakers) upgrading to better speakers will work.

Polk audio, and Boston Accustion(sp?) make great speakers, but i dont know if they offer them in the right sizes for drop in replacements in your mustang.

 

What is the impendence on the stock speakers? Most factory sound systems with stock amps run 8 ohms or even higher. Most aftermarket speakers are 4 ohm, giving a higher risk of clipping the factory system or even burning it up over time.
