Installed the Polk DB501 speakers on my ST Limited and they fit perfectly so now I am able to listen to the stereo with greater clarity and volume. I think 5-1/4" would have fit without spacers or mods. I wish it had more bass but the tweeter is awesome and super clear. I'm on a new quest to get the best sound from 2 coaxial small speakers. I would like to try the JBL GTO 528s next.Polk db 401 and they are waterproof!!!
How does the grill for the ST come off to remove the speakers?
I ordered the JBL GTO528 today. Already put the 428's in but wasn't pleased with the sound at highway speed so I am going to give the 5 & 1/4's a try
I will interested to know what the 528's sound like. Please report back. I put 5-1/4 Pioneers in mine. They are better than the OEM speakers but not as good as I thought they would be.
From what I'm told there's only like 1" depth to work with. That's why I heard the Polk db401 work. Haven't done it yet myselfTried to install the JBL GTO528 today. They will not fit due to depth. The circumference looks to be fine. Even with a spacer or shim they will or fit because your top plastic would then not properly fit. I don't think the depth of the speaker is an issue as they are listed to have the same depth as the 428 I have installed. The problem is the circumference of the magnet is a good bit bigger than the 428 which hits the back of the headlight assembly. Oh well, it was worth a try. Now I have to try and sell the GTO528 as I broke 2 of the mounting tabs off trying to get them in.

Sorry to dredge up an older thread, I just didn't want to start a whole new one on the subject. Did anyone ever determine the actual size speaker needed for the ST's? I have seen both 4in and 5in bandied about in this thread but never saw anything definitive. I have an ST-S and was considering installing something like the polk db401 or db501 depending on what actually fits and then putting a bluetooth enabled amp in the frunk to stream my iphone through. I just don't have enough experience with these sort of things to know which amp (size, power, etc) would be needed to run this sort of setup. Thanks in advance for any solid info you guys might have!!!![]()
