-- What's up forum crew --
I have been watching plenty of threads about audio upgrades, most of them a few years old. Outdated threads tend to go hand in hand with outdated technological info.
I am looking to beef up my system on a dime (big surprise). I already switched out the HU with a Sony (I know I know...) CDX unit with the flash drive capability, that I had from my last truck.
Current upgrade list to buy:
-Components up front
-Matching coaxials in the back (not necessity though)
-Something along the Q-logic/JL Stealthbox/subthump.com box to put on the side in the back. I DJ and use the back space in its entirety (seats folded down and all) - can't afford much room.
-Ideal sub for a sealed box
-Class AB 4 channel (or 5... whichever) amp
COMPONENTS:
I have been checking the forums fairly in depth and a decent amount tend to back the Polk Audio DB6501 components. Amazon puts the DB6501 at the top of their list, and from what I've seen here
, they look like the majority's fav as well. Of course BestBuy only carries the PA-DXi line, which looks to be the "new version" of the DB6501. Unfortunately, they were playing some BS like Taylor Swift
, so I didn't have the chance to truly hear what they can do, and surprise surprise the staff didn't feel like helping me out. The other top pick listed the most - Alpine Type R components. Alpine has at least two different lines of Type R components: SPR-17S and the SPR-60C. Some mention Infinity Kappas, Boston, Memphis, JL, Orion, RF, MTX, Kicker, anything but Sony, I saw a Hertz mentioned once. Just looking for some updated input, what you have, what you've heard (in person), Dos vs Don'ts... 
P.S. - I plan on mounting the tweeters in the A pillars, and drop the highs a bit so they're not overbearing.
SUB & BOX:
Pretty much looking for your experience with any of it. The three well known being Qlogic ($300), the JL stealthbox ($230ish), and subthump.com's site ($80). Even if you DIYed it with fiberboard and speaker carpet, I'd like to hear your thoughts (I'll never do that s*** again; well worth it; sounds great/like crap). As far as the sub goes, I know you can't expect too much out of a .8 cubic foot box. Some subs handle better in sealed vs ported boxes. Plus, I can't technically "go out and give it a listen" since they're not readily available. So feedback here is my goto.
AMP:
I'm aiming for the class AB 4 channel so I can bump the components up to their RMS, and bridge the the other 2 channels to run the sub. I have (somewhat) narrowed it down to the Kenwood Kac-8405 because of the consistent good reviews matched with the decent sticker price ($130 shipped - amazon). Amazon also has this Power Acoustik GT4-1200, which seems solid on paper. Solid specs (RMS - 100W X 4 @ 4ohm ; 125W X 4 @ 2ohm ; 250W X 2 @ 4ohm) with the right price ($120 shipped). However, not a single review anywhere on this thing. I know some have had luck with Power Acoustik, but I have also heard the exact opposite. The Kenwood doesn't push as hard, but for a difference of $10 more, is the -25w RMS worth the piece of mind? What's your take / recommendations for something else?
In the industry of "you get what you pay for" - I'm trying to make the right choices, just not the arm/leg choices. Thanks for lookin out!
