Hello! I have a 2015 XP1000 with a ssv 4 speaker system installed and working in it. We bought the poly rear window and have that installed as well. We recently purchased the extra 2 speaker add on for our machine but it appears to be hanging up on the brackets that hold the rear window in. Is there a way around this or am I not able to add the 2 speakers with a poly rear window? Really would like to complete the look and have all 6 speakers above head. Any ideas? Or am I out of luck and have to send back the extra 2 speakers. Thanks for any help!
