I installed this receiver in a 1995 Honda Civic, and it has been paired with Kicker coaxial 6.5" speakers. The installation went pretty smooth considering this had been my first installation, and it was especially rewarding when I powered the unit up for the first time. Overall I am happy with the unit; the Supertuner is far superior to the stock radio that preceded it, and the audio quality is very good considering the price point.

I was in the market for a new head unit for my corolla and jumped on the chance to get this player way below retail price. So I got it. Unfortunately, for me it's pretty looks do not make up for it's shortcomings.

First off, I do not know why manufacturers make push button/ knob type controls for aftermarket radios like this. It's a complete pain, especially in this player. I mean how many of you here who have this unit can honestly say you haven't mistakenly pushed the button (that switches from cd-radio,etc) while trying to put the volume up or down turning the knob? Really? It gets really frustrating after a while, that I'd rather use the control! Another thing is the cd player sensitivity. Got some badly scratch discs? Don't try in this, it won't play at all! Heck my older jvc head unit could play those discs without a hiccup! Thumbs down in that department. Another thing I found rather annoying was the random command. Let's say you want to skip that random song you just put on, guess what? It goes to the next song in order NOT RANDOM! Sound wise, I can't complain. It has excellent sound for a cheaper unit. Heck you can even connect your subs to it (and control it) which is pretty cool. The remote is more useful than the head unit controls itself which is a big plus. The other thing I like is of course the mp3 player connections, which means more music (no skipping) etc another big plus. In all I think this head unit is decent, but could be better. Like totally get rid of push button/turn knobs, they are not practical while driving. It's best to use push button only, that way if you hit a bump or something the only thing that would happen is the volume would go down or up (depends) instead of losing cool because the frickin' thing switched to something else. Plus they should really fix the cd readability. They should work on making it more reliable. In all a 3 is deserving of this unit.

The factory CD player finally died. I did not want to spend too much money for a replacememnt. I decided to buy this player because it was pretty basic and it had everything that I needed for a reasonable price.
I have this hooked up to an amplifier and the sound quality is great. I am hearing background instruments on songs that I have been listening to for years that I never heard before! The biggest difference I noted was the quality of the sound coming through from the radio tuner. It is the best I have heard. It's like listening from a CD. It also gives details of the track names and lot's of various equalizer options from vocal, to powerful to super bass.
The only problem I have is the size of some of the buttons. The preset radio buttons are really small and I have experienced an AM radio station that I normally listen to, to have some interference (high pitched noise)which I never had with the factory stereo.
It also comes with a remote control but I never get to use it.

Great sound and electronics.

Buttons as has been mentioned, were designed by a moron who never tested them to see if they can be reasonably used. Pioneer should know better. A better design would have been easy.

Faceplate delicate. Watch out. I treat mine like a golden russion egg. Dropped it once 2 feet now half the leds aren't working.

I purchased this for my son's car and he loves it! Works great and a great price. Would recommend!
