Best double din radio? Options

[cjpost]

I am looking to upgrade my stereo system and I plan on buying a double din touch screen head unit as well as two new sets of speakers (front and back).

Subwoofer capability is necessary, and I would like it to be relatively loud.

I have the 1994 gt coupe with no 8 speaker option.

I have been looking around and it seems like none of these radios are compatible with the iphone 5s without a separate cable.

At the moment the kenwood ddx470 seems like the best option with my budget (I would rather not spend more than $350 if possible

Any advice on what speakers to buy is also greatly appreciated, I can spend up to $200 for the set of four and am looking for good sound quality as well as loudness.
I need speakers that will not blow out if I am blasting the music.

Also, I have been looking around and the highest I have seen is a 22W preamp output for the speakers. does this mean I should invest in an amp as well?
I am not sure as I previously had a 99 vert with the 8 speaker set up and a single din head unit.

Any suggestions are welcome and appreciated, thank you.

switch to android. iphone problem solved lol to be honest if its just a head unit go for anything with bluetooth + USB on it.. and yeah you probably will need a seperate wire for your iphone (because they are ****) reason why i say any head unit will do is because you should power everything with amps. soooo mucb better!

if you want to do it on a budget i would highly recommend using Bassface. sound quality is excellent especially for the price. they are direct fit with no extra drilling or custom work. i have 2 8" subwoofers in the doors + 2 oem tweeters. 2 6.5" coaxials in the rear and a 15" sub (go for 12" i have no more boot space) in the boot. again... good sound quality.

be aware though. cheap speakers will produce cheap sound. i didnt have that problem with bassface. only reason i would recommend.

JVC, Kenwood and Alpine make some nice oem looking double dins.
