    So I want to upgrade my stereo but want to keep stock hu...I was told by simply adding a six channel audio control(LC61), I can achieve good stereo quality. I will be running some decent equipment and am wondering if I should upgrade hu or just go this route.
    List of equipment:
    JL audio stealthbox..you're familiar with, I'm sure.
    Focal PS165 components front
    Focal PC165 coax rear
    Arc audio XDI805 5 channel for everything.
    LC61 audio control.
    I have a tendency to trust this shop as they win competitions all over and do very quality installs. However, other installers I've talked to say I absolutely need to change the hu for better sound quality. Again, I love the stock hu and would rather keep it. I'm not going cheap, I don't think, with the equipment and just want to get my moneys worth.
    Thanks in advance for all your input!

    It is true that a new head unit will provide better sound quality.

    Will your ears be able to recognize the difference?... I doubt it.


    Just the fact that you are upgrading to Focals and a better amp is going to be a night and day difference, and it is going sound much, much, MUCH better than stock speakers.

    I ran (4) 15" subs and 2 700 watt amps of a stock deck before and didn't have any problems.

    You are going to loose a little bit of signal quality going through the line out converter, but I wouldn't worry about it, especially if you are using a high quality one.

    I have used $20 Walmart ones before with good results!

    Why would you not change out the HU? Looks like everything else is going to be top notch, I'd guess a new HU would sound way better than stock.

    A digital signal is a digital signal, and that's about as good as it gets.
    You would need some very expensive
    real time analyzers and other very expensive testing equipment to tell the difference. Only a robot, or maybe your dog, would be able to distinguish between the two.

    What really matters is what is reproducing the music. New speakers (and amps) is what will make an audible difference.

    I have some Focal home audio speakers (that I built) they are the S$#T.

    Why not just move forward with your plan? Worst case, if you don't like the stock HU and the LC61, all you'd be out is the cost between a new LC61 and the used price you'd sell it for. Sounds like a no-brainer to me.

    Well I do love the new 2012 hu...functions, etc...also, rather keep the system hidden from los Angeles stereo jackers. The owner/installer also assured me if i didn't like the audio control route after installation and tuning he would take it back 100% refund and install hu. I just didn't want to delay the eventual if the majority said the audio control wouldn't get me my moneys worth. Thanks again, guys.

    I would say pick a different amp. That ARC audio amp is fairly expensive and doesn't make much power on the sub channel. Maybe the Kenwood XR-5s?

    Just curious...I'm paying $400.00 for the amp...the other option was to do a mono JL 600/1 for the subs and a JL 400/4 for the highs...it would obviously cost more to go the JL 2amp route...will it make much difference? Price-wise I think it'll be around $200-$300 more.

    SwingCase, driver side. PVC Bike rack. Aftermarket stereo.

    He is saying get a more powerful 5 channel - keeps install easier/cheaper/cleaner, but you can do better on the price/power ratio.

    Alpine PDX, Kenwood XR5s would be good options.

    So 400 watts rms at 2 ohms is not enough for these subs? I also liked the 2 year warranty arc audio provides with their product.

    Not sure if you've seen the 2012 hu, but i do like it a lot and would rather keep a stock look. Besides, if I have a digital processor that should convert the signal to my liking...correct me if I'm wrong.

    Didn't see that it made 400 on the sub channel at 2ohms. The spec chart on their side is split up weird and they pushed it to the bottom.:confused:

    If you're cool with the price and that satisfies your space constraints I say go for it. 400 is plenty, just make sure you buy a sub (or subs) that wires down to 2ohms.

    Yeah I do believe the 10w1 JL subs in the stealthbox are 2ohm..thanks stallion.

    You are 100% right.

    If your stock headunit does everything it need then the AC unit will do you great. I'm not 100% sure but I think the AC unit does 7 volt rms output IIRC My Kenwood KDC-X995 only does 4v rms. It also does summing which cleans up the signal significantly.

    I also second Steven in trying a different amp then the ARC model.

    Why do you think a different amp is necessary?

    I'm getting a system done in my '12 in about 2 weeks too. I'll be using the stock HU with a Audison Bit Ten, 2 way Hybrid's up front (active), no rears, and a single IDQ10 in a MrMarv enclosure. All powered by a ARC 300.4 and a 500.1 Mini.

    I'm in Socal if you wanna listen to it when done.

    CANT WAIT!
