Ok...just got a 2000 Accord EX coupe...stock sound is OK but I'd like it to be better. Not looking to spend a LOT of money, and not looking for a huge amp/sub/etc setup...probably just looking at getting a new HU and some new speakers.

Looking at the Alpine CDA-7894 as a HU...will this be suitable for the stock speakers? and will there be a big difference from the stock head unit?

Also, the current head unit is taking up the entire space provided in the dash, whereas the Alpine would be HALF that size...is there an installation kit that will make that fit?

Basically, I want good sound...crisp, clear audio...primarilty for rock music...

Once I upgrade the HU, I'll look into speakers...will they really make a big difference if I replace em with some quality speakers?

I'm not looking for a huge system...just something that sounds good.
