Question Audio advice

Hi everyone. I'm in need of a little advice for my car. I'm planning on swapping out my stock speakers and headunit for aftermarket speakers and headunit. I was told from someone over at Crutchfield that if I were to replace the stock front door speakers with Infinity Reference 5030cs, I'd need to do some modification to the doors. What modifications were they talking about? All the guy told me was that the speakers I have now are bottom mounted while the Infinity'* are top mounted. Also for my deck speakers, I was thinking Infinity Reference 9633cf. The speakers are going to be pushed by the Infinity Reference 475a. I was also thinking about tweeters. The tweeters I was looking at are the Infinity Kappa 10.9t. And last but not least, my headunit will be the Kenwood KDC-MP442U. The headunit is perfect considering I want to use my iPod with it and I would want satellite radio as well. There is an adapter I would need to keep the factory steering wheel controls and everything else, but I do not remember the exact one I would need. I do not have OnStar in my car in case that was something that needed to be known. Any advice or help would be greatly appreciated. Have a great day everyone. .

P.*. If anyone has any experience with any of these components, what did you think of them and how did they meet your needs? I'm looking for clarity and some bass as well.

Thanks again everyone.

I dont have any experience with these speakers but I can tell you that if you need any mounting mods, the should be very minimal. what is the mounting depth and diameter of them? People at crutchfield dont know much about audio so take their advice with a grain of salt. I have never heard of a flat out "bottom mount" speaker or "top mount" I honestly dont think you need to do anything to them to make them work. Give me the specs or a link to te specs and I will tell you what I think

I said the same thing when the guy told me. I have some experience with audio myself. If I anything needs to be done, I'm sure I wouldn't have a problem either doing it myself or getting someone around here to do it. The mounting depth is 2-1/4 inches and the Cutout Diameter is 4 11/1. If it helps, the Top-mount Depth is 2 1/4. Spec wise, what do you think of the speakers? I've seen around the forum people mentioning your name when there'* an audio question, so I know you have experience and know what you're talking about. That'* why I was hoping you replied to the thread. lol. Thanks for any help you can provide me with.

This is for your 1999 Pontiac Bonneville, right? If so, when I looked up that car, it has 4"x6" speakers in the front doors. So a 4"x6" or a 4" speaker would work fine without modifying the door.
The speakers you want to use, Infinity Reference 5030cs, are 5-1/4" component speaker system. If you wanted to use these speakers, you would need to modify the opening for the bigger speaker to fit.

This is my guess.

yes this is my car. That'* strange because when I looked up the speaker size, I got 5 1/4 and the rear decks I got 6X9. I mean, I don't have the vehicle in my possession right now since it'* still in Florida. What I know about the speakers is that there is 2 speaker grilles on the door. lol.

I just tried again and this time the website came up with your car having 5 1/4" speakers. I just realized when I tried changing the vehicle options on Crutchfield the site didn't change them so disregard what I said in the previous post.

My only other guess for "modifying" would maybe because of the depth of the speaker. Maybe.

No Pontiac Bonneville after 1992 or 1993 got 4x6" speakers. 5.25" became the standard because it reduced cost and improved sound quality.

What the rep meant was that there will be a gap between the speaker and the mounting surface of the door panel.
The stock bose speakers have a filler to close that gap.
I forget if that is removable, but I just put my Infinity 52.7i'* right in and put the panel back on. No doubt I'm losing both SPL and SQL, but it'* 1000% better than the stock Bose 5.25" woofers.

For the tweeters, YES, upgrade them. The highs will be a lot more crisp and clear.

I'm planning on replacing all of them and upgrading with tweeters as well. I may be able to get a custom installer out here to do what I need done if there is anything. If that makes any sense at all. lol. What do you think of the speakers I chose by the way? How do you like your Infinity'*? From my experience with them, they are extremely clear and they have a little bass to them as well.
