Just in process of installing an Alpine cd changer in my 52 plate dynamique, have removed the storage unit from under the seat and wired the changer up to the headunit and slotted the wire under the carpet, all very easy, now the bit i am stumped at, unit didnt have any brackets so using 5 cm wide industrial type velcro to hold it down, have measured the velcro up but when trying unit out i have found that if i put changer under the seat if it was fixed down i couldnt get the cd mag the whole way out the changer, any tips folks? i am really wanting to get this finished in an hour or so
