I know this isnt the a/v forum but no one answered there before and i want to buy this tonight Im looking for a 7" monitor to mount in a double din that measures 4.5 by 7.75" So far the closest i have found is a farenheit monitor that measures 4.5x6.8 which i was about to buy but then i read you could separate some monitors from the housing so i was wondering if i could buy this Power Acoustik for a lot cheaper and separate the monitor to use or if i can only separate flip down overhead monitors. PA makes farenheit so the quality should be decent. Thanks a lot for any help you may have and please recommend any monitors you think will work for me Sorry for posting here
