How to change the rear speakers in a 318ti By Eric Miller As you probably know, the rear speakers in a BMW 318ti are not a standard size. The only aftermarket speakers that fit without modification are MB Quartz (size 4T), there...

I cannot beleave 4" speakers are enough for most people, I was thinking 6x9 adaptors but I dont see anything remotly close avalible... I guess butchering the rear parcel trey is the only way to add in decent sized speakers? | | | Quote: Originally Posted by 32styledTI I guess this is the only way to add larger speakers into the back of the car?

There used to be a German company that made adapter plates for 6 inch speakers (they sold thru Ebay.de). I have not seen those for sale anywhere, they had disappeared from the market years ago before I even had the car, LOL.. It just so happens that the 4 inch was the easiest solution... | | By Bozola on 05-30-2011, 12:03 AM | Did this today. Time consuming, but easy enough for a non-dyi like me. Sounds awesome. | | | Excellent DIY. I used these speakers and it is great. | | By kmsnsx on 12-27-2011, 04:45 AM | FYI, this can be done without removing the seat bolster, just have to flip the seat forward and you can get to all the screws by moving the side carpet | | | | Last edited by austinindian; 01-23-2012 at 10:28 PM.. | | Thank you, familytruckster. I saw CirrusSR22 posted up a hack with the Polk Components speakers (5'' one I think). Might not be as elegant, but I might look into that as well. | | | Looks like we lost the pictures. Does anyone have them? | | | OEM rear 4 inch speakers on sale ECS tuning, at least a/o last Friday, had a number of the OEM BMW 4 inch rear speakers on special/sale. No connection with ECS except I shop there sometimes, seemed like a decent price cut on a very hard to find thing. RAS | | | Well, I bought this speaker system: Rockford Fosgate Prime R152-S 5.25-Inch Component Speaker System And my plan was to do the hack to modify, hopefully hide everything with the plastic panel. | | | Quote: Originally Posted by austinindian Looks like we lost the pictures.

I found the original pictures and re-uploaded them, hopefully this procedure is still relevant | | | Thanks for this. My original speakers are blown and this helps a lot. I'm doing this switch over the weekend. | | | | Currently Active Users Viewing This Tutorial: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is On | | | |
