Re: 2006 honda accord
I have an 05 Accord now, and was looking into source unit replacements and such. Metra has two kits available. One kit replaces the factory stereo (and climate controls) with its own, this is what it looks like, and its expensive: http://cgi.ebay.com/NEW-MODEL-HONDA-...QQcmdZViewItem
The other one replaces the pocket below the radio with a kit that can house a single din radio, that kit, which is tons cheaper, looks like this: http://cgi.ebay.com/ebaymotors/Honda...31872566QQrdZ1
For me, I don't like either, and instead, I'm going to use a JL Audio Cleansweep to integrate my speakers, amp, and sub with my radio.
You can add speakers, amps and subs to an Accord easily, its just a matter of what you want for the source.
