  12. #PainIsGain on December 21, 2020 at 7:44 pm

    Do the class collision repair teach you all of these…

  13. Stig & Aston Dogg on December 21, 2020 at 7:44 pm

    Hi. Would you still use an epicentre with a dsp? And where would you mount it?? Between unit and dsp, dsp and sub amp? Thanks

  14. gin ngo on December 21, 2020 at 7:46 pm

    Marks knowledge + video tutorials = mind blown !!! Thanks Jedi Master ..

  15. Edwin Karani on December 21, 2020 at 7:47 pm

    Thanks man. For simplicity what do you need as a complete unit? Man this is so much…

  16. C White on December 21, 2020 at 7:47 pm

    I wanna thank you for all the knowledge Ive picked up since subscribing to your channel. I pretty much watch this channel just aout everyday and some videos 2-3 times. I have a 300 with Beats Audio and I have had the beats audio removed and replaced the 6×9โ€™s with 6.5โ€™s and replaced the factory with 3.5โ€ with some new ones. I have added a 15โ€ kicker L7 4 ohm sub. I purchased the LC2i because at the time I figured it would work but Im missing sound. Im running a sub amp and an midrange amp but my rcaโ€™s wont work together. Its either one or the other to get sound and Im only able to use one channel on my highs amp. Ive been told I should have purchsed an 8 channel LC but at this point my trust is shot. If I could get any input I would be grateful. I would hate to have to pay a chunk to get everything redone. Thanks in advance.

  17. Jose Nunez on December 21, 2020 at 7:49 pm

    I have a question i have a aftermarket radio and epiccenter and a dsp 608 what the order i will connect it? Thanks love the video has help me alot

  18. derek dauzat on December 21, 2020 at 7:52 pm

    can i use the new (epicenter plus) instead of lc2i?

  19. Nathaniel Taylor on December 21, 2020 at 7:52 pm

    If I have bose factory amplifier and dont want bypass just add a amp and subwoofer. Would tapping into the 6ร—9s with the lci2? If so would I tap the line before or after the factory amplifier?

  20. Paulo on December 21, 2020 at 7:54 pm

    Help. Do you leave the amp at the same frequency/settings or change it when using an Epicenter? I have a few songs that sounded way better before the epicenter. Iโ€™ve already tried testing various settings on the epicenter and I canโ€™t get those songs to sound good like they used to.

  21. Brandon Lee on December 21, 2020 at 7:55 pm

    I think it’s safe to say AudioControl spends A LOT of money on R&D (maybe too much!)

  22. Team30HzBelow on December 21, 2020 at 7:56 pm

    my dm 608 stays on after i kill remote turn on . so i switched + and remote and now it works as it supposed

  23. Daniel Riser on December 21, 2020 at 7:57 pm

    Your that dumpster diver dude.. I know its you

  24. Jay Kyle on December 21, 2020 at 7:58 pm

    Audiocontrol used to make a model called the ESP-3
    it’s a center channel/spatial enhancement processor that was very cool

  25. John Carnahan on December 21, 2020 at 8:00 pm

    I got confused and just hooked my speakers straight to the battery so they would have enough power! Works great! But really thanks for the videos your the man!

  26. neivan edmund on December 21, 2020 at 8:01 pm

    Hey if I’m running both an epi n a crossover ,should I put the epi at the front or at the back of the crossover plz reply๐Ÿค”๐Ÿค”๐Ÿค”๐Ÿค”

  27. Mechanical Vegan on December 21, 2020 at 8:02 pm

    Why is the Epicenter Plus Discontinued? Seems like an awesome product. If they’re still making the Epicenter, why not the plus? Does it offer too much amazing functionality that competes with a different product they want to sell us additionally? Seems really well made. Like if I buy one of the few that are still available, it will last.

  28. Nathan Capestany on December 21, 2020 at 8:04 pm

    Great breakdown. This was worth every cent. Wait I didn’t pay for it. I feel like I should have. Keep up the great work.

  29. Honda Rincon on December 21, 2020 at 8:04 pm

    QUESTION. If my head unit already come with RCA plugs. Do i really need a LC7i ? I know i am using the Epicenter to my 2ch Sub Amps. What can i use to control my Highs and Mids. 2000 Chevy 1500. 6.5 and 4×6 Skar. Skar 12VD subwoofers

  30. SuperElekta on December 21, 2020 at 8:04 pm

    I like the precision in your concise explanation

  31. Dashaun Huston on December 21, 2020 at 8:05 pm

    I have a 2020 Ram 1500 Laramie with the 12 inch screen. Iโ€™m in Michigan. Can you do my install? I saw you provided consulting.

  33. Mal'ak Ban YAHUAH on December 21, 2020 at 8:08 pm

    I enjoy your videos. I have a 2017 chevy express 3500 and want to put in a system. Do you have any videos on installing a system in a van?

  34. nick nugent on December 21, 2020 at 8:08 pm

    I’m interested in learning more about how to integrate a fiber audio system and an aftermarket set up.

  35. Ramos on December 21, 2020 at 8:09 pm

    Would you still need an epicenter if you go with a DSP amp such as the D6-1200 or the JL Vxi amps?

  36. Brandon Lee on December 21, 2020 at 8:10 pm

    AC R&D Team: 2 Things: I wish the LC7i’s "Accu Bass" freq range starts lower than 20 Hz, like 10 or 15 Hz. Only then a lot of "Bassheads" would be inclined to take advantage of AccuBass now that more and more newer vehicles come with a high-end touchscreen factory radio such as on my Ford Edge. I also would like for the AccuBass to be optional for the other channels because now that I’ve upgraded my door speakers (mid-bass), I’d like to make up for the bass roll-off in them as well. I’m talking to you AudioControl R&D team! =]

  37. Brandon Lee on December 21, 2020 at 8:12 pm

    Wait, do I need a LOC if I use an Epicenter? Does the Epicenter act like a LOC?

  38. Felipe Iturra on December 21, 2020 at 8:12 pm

    Hi man, thanks for teaching us about all this wonderful thing called car audio. I have a question, i recently bought a lc7i to keep my factory system, is any problem to wired the lc7i from the dash to the truck with 18 gauge wires, i see and i wanna pick a metra-mc918, 9 wires with cover with the same colors for 4 main speakers and a blue for remote. If that not work, what is the best opcion ? Thanks again !!!

  39. #PainIsGain on December 21, 2020 at 8:14 pm

    Take out the fact that with time you grow to know more out of the equation

  40. Romans116 on December 21, 2020 at 8:16 pm

    Whatโ€™s the different in having an EQ letโ€™s say on your phone using Spotifyโ€™s band EQ vs preamp EQ?

  41. Pritpal Loi on December 21, 2020 at 8:17 pm

    Hey Hi Mark, I am new to car audios and have Acura RDX 2019. I have Skar RP-1500 watt amplifier and EVL 1250 RMS Sub with a peak 2500 watt both balanced at 1-ohm Impedance. I want to get it installed in my car but not sure if I need to upgrade the OEM ALTERNATOR. I am okay with an additional battery if required. I was watching your video and expecting you to show & explain that part too if needed and what other ways to upgrade with keeping default ALTERNATOR.

  42. Colton Sanford on December 21, 2020 at 8:17 pm

    Thoughts on AudioControl v. Rockford Fosgate for this equipment category?

  43. Muhammad Ali on December 21, 2020 at 8:18 pm

    So essentially I can either use LC2i and epicenter or simply go for epicenter plus and get the same quality of sound? (I am using the factory head unit).

  44. theimmaculatecrown on December 21, 2020 at 8:18 pm

    Great video! You explained everything I wanted know and more.

  45. Na Baddame on December 21, 2020 at 8:18 pm

    Just to clarify the order these components go, so from factory head unit would be line out converter to equalizer to crossover to amplifier?

    What if I wanted to add the epicenter into the components listed above? What would the order be? The epicenter right after the crossover and before the subwoofer amp?

  46. steph steph on December 21, 2020 at 8:20 pm

    This or bavsound?

  47. David Dey on December 21, 2020 at 8:24 pm

    But HOW do I run a 10inch sub with a small factory 5.5inch sub? Toyota MR2

  48. Henk De Kul on December 21, 2020 at 8:27 pm

    if you need a EQ you dont have the setup you want/need.

  49. Dj Acemoney on December 21, 2020 at 8:29 pm

    Would you still need to use a Line output converter when using the amplifier with the built in DSP? Or can you go from the factory speaker wire straight to the amp?

  50. Alex DelGuercio on December 21, 2020 at 8:30 pm

    Thank you so much, Mark. Your videos have taught me all I know about car audio. It appears The Epicenter functionality is not built in to the DSP. Is it as simple as connecting the RCA subwoofer outputs from the DSP into The Epicenter and The Epicenter outputs into the sub amp?
