Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

I have the shop checking the distance from the middle of the mid to the middle of the tweeter to see if it will come anywhere near the tweeter grill.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi, I have read all the posts on upgrading the speakers in the dash and rear in my C4 and all the fun and games involved. I have found that Infinity launched 4" mids and a 3/4" tweeter on one plate (see Kappa 462.7CFP). This would appear to have advantages of the mid and tweeter already being held in place. I have the shop checking the distance from the middle of the mid to the middle of the tweeter to see if it will come anywhere near the tweeter grill. Assuming it does, the plate will also let you create your own holes to secure it to the grill with. SO that should be relatively straight forward. The only thing I am unsure of is how to make them airtight and is that really necessary? Anyone who has done the mod with other speakers let me know ? Cheers Stu

POST 2Original post

I fitted the 4" Bose drivers front and back. They are the ones found in their Bose 901 range. I don;t have door speakers and found the infinity lacked any real grunt. The Bose drivers are punchy but you have to be careful how you wire them as they are 4ohm. They have good bottom end but I also fitted a 10" base woofer into a half-cut base-tube which sits on my rear seat. The setup is driven from a Kicker amp fitted in the front bonnet. The sound is fantastic and extremely punchy with excellent clarity even with the rag-top open!

Cool, I will have alook at the Bose speakers Stu
