I would never spend 42 minutes on a video....except this one. So much info...thank you!

Thank you for taking the time out of your day to do these videos. I’m new to the audio scene and have so much to learn but thanks to you I’m learning something new every video I watch.

Hello, I just wanted to thank you for taking the time out to make your videos with the amount of detail and information you provide. I have been watching the info you put out while putting together what system upgrade I'm doing on my 2014 SGS. The RFG Stage 3 has been my pick. Anyway thank you again for the video's, they are truly appreciated by a guy in Ohio.

Great video Carlos. Thanks for taking the time to show us these products.

[@paulharmon628]

Thank you! I am an audio guy forever, get all the lingo, testing and ratings you get it and I am new to the HD world so hearing you apply it to the bike world has been absolutely awesome, my Ultra will be in your shop soon! Thx and keep it up!

Always always overwhelming information and I can't get enough..lol sitting here with my notepad... you just changed the direction I was going with an up coming build and saved $$$

[@buyck50]

We are blessed to have you because no one else is giving out this type of info

[@kirschbaumr1]

Thank you for such an in-depth review on a multitude of speakers and also giving feedback on what the end-user is trying to achieve, which may drive a different selection. Will certainly be doing my homework and adding rear audio when I go back through next year - not happy with the money invested to date with the 400W system 2 speaker upgrades I've added thus far.

[@01Lightning]

Thank You Carlos for a great video. I wish I had found you last year. Seeing that your a couple towns over from me, I will be stopping by

Carlos has awesome customer service skills. You can tell that he cares about educating as well as building his business. It goes a long way when your installer is reachable and hands on!!!

Dude, I used to do car installation from the beginning. You could say I was one of the first by installing 2 JBL professional 15” subs into a 81 Honda civic back in 1983-84 when there was absolutely nothing but a small handful of speakers and amps on the market. You are certainly in a nieche industry. Well done. So much info and you explained it on point. Keep doing your thing!!!

[@TrellosAfstralos]

Excellent Review I Never Thought I Would Sit Through a 42 minute Review But After Watching It I Have Now Watched it 3 Times. Congratulations Carlos And Thank You For Your Time You Are Not Obliged To Spend Your Time After Work On Doing This But Obviously You Love What Your Doing Not Just For The Money.. Big Ups From Greece After Watching Your Videos You Sir Are A Real Professional Business Man Looking After Your Customers Will Be Calling You From Greece You Have Just Won A Customer.

[@efortson1566]

Mad respect Carlos, thank you so much. I have been waiting for this video to decide which direction I was going to go. Thanks for educating us/me. After months of watching I’m ready to tackle my upgrade. Starting with a 2016 RGU with stage II boom 600W. Starting with the Braille G30H. Radio flash, DSR1 PNP. Audison power and ground blocks. Anybody who uses belleville washers for their connections understands power distribution. Once the bolt is tighten to torque it will not back out, not even under HD vibration. SD 2400.4 Evox 4ohm. Starting with 4 Ground Zero 6.5 GZCF. Cant give up saddlebag space so the new GZ yellow basket coax was a game changer for me. Once the 8in coax is released I will run the 4 6.5 in parallel on ch1 and 2 and a 8in in each saddle bag lid on ch 3 and 4. OFC wire of course 12ga speaker feeds.

Best 6.5” non coaxial review Carlos!

[@donalddavis7160]

Really appreciate all the knowledge you give during your videos. I have a question for you. I’m toying with the idea of running the DA MP654 in the fairing and 2 6.5s in the lowers. What are your suggestions for powering the horns? I’m going to get the SD EVOX800.4 for the drivers. Do you think the Soundigital nano 250.2 will work. Any input is welcome. Forgot to mention, I do have a Rockford dsp Thank you in advance

[@BlackEyeSRT]

Thanks for another awesome video I want to pull the trigger on a set of the diamond audio mp654 coaxial but my question for you @NVSAUDIO is would the ground zero produce more midbass because that's what I'm lacking so far

Thank you in advance for your time and knowledge👏👏👏👏

Some invaluable information here thank you very much !

[@johncooper5830]

Hi Carlos First thanks for your video's your knowledge is priceless 👍 I have a question for you, I am in Germany with the military and there is basically nowhere to go when it comes to motorcycle audio. I have a 2008 road king with the rockford lid kit and the TMS69 speakers then I have the pbr 300x4 and the MTX Bluetooth controller my question for you is, I am going to install lowers and would like to know which 6,5 would be better the hertz or ground zero's, will the GZ fit in the lower pods without modification and will the pbr 300x4 be able to handle the 4 speakers? Thanks John

[@burlyjuan]

Speaker pod mod on batwing pods too, or just the Road Glide? Your videos are super helpful!! Thanks and keep them coming!

[@jeffg9058]

I smoked the tweeters in my Rockford fairing speakers in like a week after adding an amp to my system but they didn't sound good before anyway. I did the bag cut in kit and put Polk 6x9's in and those are doing fine

[@1983samgonzalez]

Thank you for all the information

[@projektxent]

Great video. I am seeing, including myself getting the Advanblack pods and lids. Durable, looks good and cheaper than Harley. My question is which of these 6x5s fit an Advanblack lower fairing and lids?

[@RAWDAWG123175]

Was looking to upgrade my fairing speakers. Between the yellow basket ground zero and the diamond audio mp654 but now thinking of the diamond audio Mspro65 component speakers and the diamond audio m1srt tweeters. My question is won’t the diamond audio component with the tweeters have more mid bass and an overall better sound than the other two coaxial speakers?

[@newo2266]

Great video, thank you for all you hard work. Do you know if the ground zero speakers will fit in advanblack speaker pod on a 2009 electra glide?

[@NVSAUDIO]

They will , you just need to use the included 1/2 spacer and you might have to turn the speaker upside down to get the terminals to clear

[@DCGDGK1]

I was wondering if you have to do the fabrication to a 2020 Street glide. I want to put the 6.5 trumpet (Diamond Audio) speakers. But not sure if it will fit stock or if I will need to fabricate it. If you could please let me know I would really appreciate it. Thank you for your time.

Great videos and thanks for sharing all you know.. I have a rider bike with Hertz 600w HMP4D-HD amp 2 speaker setup. will the Ground Zero gzcf 6.5 spl be a great fit to add some base? i don't mind making the pod mods. thanks again.

[@harleyd4280]

Great video ,, more than helpful info-

[@csj9619]

Absoloutely love how manufacturers are putting HLCDs (horn-loaded compression driver) as a coaxial tweeter. Although I've not heard the particular driver shown in this video, I've been impressed with Mmats amps, subs and speakers.

[@cmeador1984]

awesome video. I've currently got a moto600.4 looking to upgrade do the 800.4evops, just trying to decide on speakers. I saw another video showing the EX6NCD fits the ultra pods with no mods at all. Can you confirm? this would be on a 2017 ultra.

[@ral819]

Carlos, I currently had installed the 800.4 Evo with Ground Zero (GZCF6 6.5SPL) and DB Euphoria (EX6NCX) speakers in lower fairings. What's your thoughts on this set up ?

[@josephjohnson1284]

Thank you for your time my brother

[@newmoney8128]

Definitely good information My only question is you said you do a hurt 6x9 with ground zero 6.5. or mmatz 6x9 with ground zero 6.5. why would you not match mmatz with mmatz or hertz with Hertz.. And can that ground zero 6.5 fit in the fairing not so much the lower fairing but the inner fairing

[@donalddavis7160]

Considering getting the MP654. From you and a couple others I’ve heard the mid bass is pretty weak. Do you have any experience with Audio Legion MR6N? This speaker looks identical the MP654. I’ve heard they are just as loud and have more mid bass. Can you input? Thank you in advance

[@Heavy69Metal]

Always good info

[@morlaw5290]

With the new galeforce f3s and other new products. Which one is the lowdest and clearest? Also more would be nice as well getting louder on lower power.

[@tdigiulio2]

Carlos..i bought 2 set's of GZ and ran them with your recommendations and with the SD800.4 setting with DSR1.. and now have them cut out when raising volume. I checked all wires, amp output with ohms..ground to battery. Any recommendations

[@mexquint]

Very informative and excellent video! I'm wanting to do a new build on a 2016 RG, leaning towards the Ground Zero 6.5 in fairings and the Fosgate 6X9's in bags would the Sound Digital 800.4 amp be sufficient to push these 4 speakers or should I jump up to 1200 amp?

[@NVSAUDIO]

The 800 would Work Well But the 1200 would give you way more mid bass . I would run the 1200
