Need HELP with speakers on Mini Please!(Pics inside)

[StokeyMax]

Hi guys, new poster to the forums but have been browsing for a while now!

Got my mini r50 back from the garage today as i sent it in to get the audio system upgraded! They fitted the amp fine and subwoofer but had trouble fitting in the 2 other speakers, i was happy at first but when i turn the volume of the volume past 25 (goes to 50) i get a nasty crackle/interference in the factory speakers, which is understandable as they are not wired to the amp. They suggested getting a 'stealth shelf' as my parcel shelf is an awkward shape and the speakers cannot fit in, however i am finding it very hard to locate one for this mini, tried ebay/browsed many custom mini sites everything!

So please can you help me get out of this dilemma as i do not feel i am getting the full effect out of my £250 audio set, which is a bit of a let down!

Ideally i want the other 2 speakers fitted and i really dont mind where! parcel shelf, door anything!

They are a mini specialists garage, so i think they know what their doing, but this situation has got them!

Here are some pics:




I have 2 of these, both identical



Would really appreciate it if you could help me with this!! Thanks
