Sup guys! I've been itching to upgrade the sound system in my 4runner but was more concern with getting the truck to run and ride smooth 1st than upgrades and mods.

Here's what i'm thinking:
KICKER 41CST204 (Tweeters)
KICKER 40CS654 (front & rear speakers)
Kicker PT250 10" (powered sub)
Alpine KTP-445U (4 channel Amp)
************* (Head unit)

Can't seem to make a decision as to what head unit to get, so many models and features i'm going dizzy.
What brand are you guys more familiar with?
And also i was thinking double din but i see A-LOT of guys on here using single din alpine HUs which cost more than some double dins why? Enlighten me please.

P.S not interested in a bunch of features that i'm hardly going to use.

the kicker coaxial speakers (40CS654) that you are looking at, will not require you to purchase tweeters. they have the tweeter built in. From past experiences I would highly recommend staying away from kicker stuff. Also if you want a little better sound quality, go with a set of components over the coaxs.

In my truck I've got a Kenwood DPX500BT, and I absolutely hate it. I'm looking for something to replace it with as well. A nice head that my buddy's got is the Sony XAV-68BT. I'm thinking i might pick one of those up when they go on sale.

I just put in one of these:

Amazon.com : Pioneer AVHX5700BHS Double-DIN DVD Receiver with 7-Inch Motorized Display, Bluetooth, Siri Eyes Free, SiriusXM-Ready, HD Radio, Android Music Support, Pandora, and Dual Camera Inputs : Car Electronics
It has a ton of customizable features for aesthetics and sound and the tilt out 7" screen along with the specially coated screen cures the sun factor. The only issue is it barely hits my stick shifter when in park but even when it does is self retracts a little bit. Really cool.

I also put in some apline R series components in the front and rear doors. And NVX amp and a Kenwood powered sup under my seat.

I was pleasantly surprised by how LOUD I can turn it up before it distorts.

Ever heard of NVX? They're a somewhat newer brand, the "house brand" of SonicElectronix, from what I've heard.

Anyways, I have a set of NVX 5.25" speakers in my rear doors (Coax) and I think that they sound better than the Alpine Type-S 6.5" coax speakers that I have in the front.
NVX offers both coax and component speakers too, just depends on what your preference is.

As far as head units go, Sony released a single din a few months ago with a built in MOSFET amplifier that pushes 40w RMS to each speaker, with great reviews. It'd be akin to running a lower power 4-channel amp, without running the wires and using space that an amp would take. I really want to get one, but have other things that are a higher priority.

Also, just remembered that if you're replacing your rear factory speakers for the first time, you'll need to get an adapter plate since the factory speakers only have 3 mounting screws, whereas most of the aftermarket speakers have 4 mounting screws.
Here's the ones I used: http://www.car-speaker-adapters.com/items.php?id=SAK039

Just my .02

x2 on the NVX as the amp I have (a class D amp) is rated for 110W RMS (I Think) but a youtube test I was watching showed it actually closer to 175W RMS. A lot of positive things written about the NVX stuff

They're quite impressive, at a price that isn't too bad.

No reason to go cheap, if you've waited on a sound system to get the rest of the truck in order wait a little longer and save up for the right sound. All up to your personal wants and needs. Quality over quantity

Oh ok.. the Sony XAV-68BT looks sweet but i've read some neg reviews about it. Thanks for heads up!

Couldn't agree more.. thanks!

I went with a Pioneer DEH-80PRS. Single DIN. Pretty customizable with a lot of options to grow your system and not too flashy. I'm pretty pleased with it. I've always had good luck with Pioneer stuff.

Pioneer DEH-80PRS CD Receiver at Crutchfield.ca

If you get one with touchscreen the motorized face is pretty nice, tilts up for perfect viewing angle.

I'm not a fan of Sony & would get Pioneer or Alpine for a HU. For amps & speakers JL Audio all the way.

I've been very happy with my Alpine CDE HD149BT single din deck. It's not too fancy but it has all the features I wanted like Bluetooth, HD radio, and iPhone compatibility. The single DIN left room below for my 2M radio, but you could mount a CB, switches, gauges or whatever below. If you want navigation or DVD then you'll have to go double DIN.

This is good advice.
I like Infinity speakers as well (made by Harmon kardon). Never had a problem with them and I've been using them for over 10 years.
JL is very good stuff as well.
For HU I always prefer Pioneer. The quality seems to always be there for me.

I run kenwood hu( it's ok, non intuitive programs) kenwood exelon 6.5. Factory rears( for now). I used to love kicker amps, not sure now though, I've heard no good things. Jl is top of line imho.
