Re: CDT-61a, will in fit in my 97 Civic? & some other questions, thanks
Can't guarantee they'd fit, there is quite a bit of room once you cut out the pointless plastic peice that sits behind the stock speakers. You will really need to measure it, but getting to the speakers is extremely easy, just pop off the grill. For the rear i wouldn't go with components, waste of money. You really don't need anything, so maybe try with just components and disconnect your stock speakers. Thats all i have in my civic and i'm happy. Taking the rear speakers out will take a while your first time, need to remove bolsters, then rear deck, and is quite a bit harder than it sounds. For the sub if you are on a budget don't go with JL. One sub will be fine for you since it doesn't appear you are a craving 155db levels. Look into the Elemental Design K, Adire Audio Shiva, Diamond CM3, put one in a ported box tuned to about 28hz, and you should be very happy.
