Question: Is it possible to hook subwoofers up with the head unit?
Document: This unit sounds good. I drive with my windows down a lot and it could use an  amp to sound louder. Only thing I dont like is the fact that the head unit stays lit if you hook it to constent power.
Works Great In My 89 Crown Vic No Amp And It Sound's Perfect Very Clear. Love This Head Unit Would Recommend.
All i wanted was a pioneer head unit that had an AUX port so I could play songs from my iPod and i got this one & it's just what i needed. I love it!
I should of spent a little more on a more flexible head unit to connect to my two amps. I had to use speaker wire to connect front out to amp, not the best with high end set up. RCA out is for sub amp.
I wanted an inexpensive head unit for my 95 Nissan truck. This works fine. Wish it had a USB plug but I can't complain too much for the price. It has a aux port so I bought a male to male wire so I can plug my iPhone into it.
This is a good unit for the cost. I use this in my backyard bar with a AC to DC converter. I have installed several head units in my day so install was not a problem. If you have to soley rely on the instructions it could be challenging. The sound is better than the old unit and it has plenty of power.
The head unit itself as a whole is really good, it will do everything you need and I think its very nice looking. (Not cheap) The only big problem I have with it is that the adjustments for low and high notes can be simpler for everyone. I had to really mess around with it and do a few Google search's to get it just the way I wanted it to sound.
DO NOT BUY! the product didn't even work. Complete waste of money. I wish I never would have even considered buying this. If you want to do it right, go in a best buy and buy a head unit their, don't do it the cheap way, trust me you will have nothing but disappointment. I'm just basing this off of personal experience.
This radio has exceeded my expectations!!! I was expecting a low to mid range head unit to replace my factory radio but this Pioneer is a beast. Everything works as it should, the EQ in the radio is quite good with 3 customized presets plus a few others, the AUX port has no whining or air, the display is bright during both day and night, and its all easy to set up.
This head unit works great however, if you drive during the day like most normal people do, you will notice how hard it is to see what the head unit is displaying.. When I try to adjust the volume to a specific level I can't see what I'm adjusting it to due to the glare from the sun and lack of brightness in the display.. It's a headache for me personally.Other than that it's a great head unit.
Answer: Yes. You will need to buy an Amp Kit too though. An amp kit is basically a collection of necessary wiring to hook up your whole sound system: head unit, car battery, amp, and subwoofers.
