head unit question

[Third Eye Vision 0]

I havn't posted here in awhile since I was comfortable enough with the stereo setup I had in my Altima. But I just bought a new car and need some advice on whether or not I should keep the stock deck and run a LOC or if I should replace it with an aftermarket deck. A little background on the vehicle, 2007 Chrysler 300 with a sound package that gives me 8 speakers and an amplifier to run them. Three 3.5s on the dash, 2 6x9s in the front doors, 2 6x9s on the rear deck, an infinite baffle 8 inch subwoofer housed in the rear deck and a 368w amplifier. I kept the amplifier(sae100d) and subwoofer(z15) from my previous install, so they will handle the low bass. I don't plan on changing the speakers anytime soon, other than disconnecting the 8" sub, so my question is would it make more sense to just run an LOC for the sub/amp?

My only complaint with the stock deck is not having a usb port for ipod integration, but its not total disappointment as it has an AUX jack. I was pretty sold on the idea of the LOC, but I saw a few posts on here of people complaining that they felt the subwoofer amplifier wasnt getting enough power to it or something along those lines. So I started looking on crutchfield for decks, but couldnt find any that have low, mid and high crossovers built in, just low and high. Maybe I misunderstood about the LOC deal, so if anyone can shed some light I'd appreciate it. And if I did misunderstand, point me in the direction of a quality LOC that will handle the job. Thanks in advance.

And I forgot to include that I only plan on using the LOC for the subwoofer amplifier, I'm going to continue to use the built in amp to run the stock interior speakers. So I don't need like the 3sixty or anything crazy like that.

Show me what you mean by LOC.

You want a head unit that is 3-way active capable?

LOC = Line out convertor. Meaning it takes the high voltage (Speaker) output and converts it to a low level voltage output to go into the RCA input jacks on an amplifier.

If you are looking at doing any type of processing you will need an aftermarket piece like the JL Audio Clean Sweep, Rockford Fosgate 3Sixty.2 or similar.

That's what I thought but I wasn't sure.

well like i was saying i plan on keeping the stock speakers for now, so im assuming the stock deck has preset crossover points for all the stock speakers. it gives me a basic eq adjustment of +/- 6 for low, mid, high. and the stereo sounds fine, i just want to install my sub for more bass. it already sounds better than my last install ever could have without hacking up the interior to add tweeters. i had 6x7s in the doors and 6 1/2s in the rear deck and no amp powering them. so i had no mid bass, and my legs were blocking the speakers so there wasnt much clarity on the highs. have any of you guys ran a LOC and had success with it? I just don't want to underpower my sub anymore than it already is. its a 1000w sub on a 600w amp.
