I am looking for some advice on if I should upgrade my head unit or not. Currently I am running a Kenwood KDC-MP438U cd player. It works with most IPod's, has an Auxiliary port, and does most of what I need. However I am looking at getting a Kenwood X794 head unit which basically would just add time alignment and a better EQ system from what I can tell. But is it worth the 160+ to get the new head unit?
The rest of my gear is getting upgraded as well. Right now I blew a rear crossover on my db6501's so I am running just my fronts bridged off the MTX Thunder Elite 404. I am still running my JL Slash 250/1 for my Treo TE sub.
Currently my fronts and rears are Polk db6501 components. The rear's are disconnected since I blew a crossover on my passenger rear. I plan to order the replacement part from Polk, but am debating re-connecting them to the system at all. I might connect them to the head unit just so that's done for when I sell the car.
I will be moving from the MTX TE404 which only lets you specify a high pass or low pass via a button which auto sets the crossovers to a Sundown 125.2. This amp lets you manually set the xover's for the channels. While it is a 2 channel amp, I can later on run all 4 pair of speakers from it, but would only be getting 80 watts. But with the ability to crossover the fronts and rears (both are 6.5's w/ a separate tweeter) I would probably be fine since I can tweak them better. To start with however I plan to run just my front components off of them. I need to set the gain a bit lower since the speakers are rated for 100 wpc continuous and sending 125 might blow them.
On the sub side I am moving from my JL Slash 250/1 to a Sundown 1200D. This amp is rated 1 ohm stable so I can get a massive amount of juice from it later on if I decide to add another sub. My Treo TE sub is a dual 4 ohm sub so we are going to wire it to present a 2 ohm load to the amp so I can get ~700 watts from it. The sub is also rated at only 500 watts max so we will be setting the gain a bit low on this as well. We have to wire the sub for 2 ohms as @ 4 ohms you only get 325 watts.
So given the gear I am getting, do you think it's worth buying a new head unit for basically just time alignment and the ability to set the crossovers from the head unit rather than the amps? All comments and questions welcomed and appreciated.
