2002 q45 system help...

[griff]

new to this forum stuff so if i am repeating any already discussed topics i apologise in advance. i have been searching all over for a solution on installing an aftermarket cd/dvd player into my q45 along with amp and subs. i have 2 diamond audio d612's and a crossfire vr1000d amp to push them. is there any place to mount other than where the tape deck is because obviously it wont fit there? the space is too small. im trying to keep the quality look of the q so i would like to do as less work to the dash as possible..but will do what it takes. also, if i was to keep the stock tape deck would this take away from the sound quality of the subs? and how would i go about adding the amp to the stock system. last, where would i find that cima grille?
