Nvs Audio’s review of the new Hertz motorcycle amp SP 4.900 

@NVSAUDIO I bought this last year and only have a 6 month riding season and now it has a dead left rear channel and if it only has a 1 year warranty then it's now out of warranty. I will probably send it back to Hertz for repair and then sell it! It was installed by a local audio shop.

Hertz really stepping up there game now. I wonder will they have a full line of these amps coming out? Always keeping us up to date thanks Carlos your the man bro.

Plus this amp is like water proof to an extent. I read about it it’s a kick ass amp ! I’ve got there 8 inch SPL show in my 4Runner doors they go down to 50 hz . I don’t have them running that low ! Your right on hooking up one of those three wires . Also three wires will be more prone to failure than one wire will be . You look like you have your work cut out for you I’m use to a little more room under the front seats ! Great video man information is through the roof ! Keep on rockin with hertz!

I’m slowly learning this stuff…. I wanna learn it all tho… very interesting…my bike still stock!

CARLOS NEED A REVIEW IF THE ALL NEW SOUNDSTREAM RADIO WITH A LOT OF INTERESTING NEW UPGRADES. LET US KNOW WHAT YOU THINK. LOOKS INTERESTING! Thanks

Hi Carlos, congrats for your useful videos. At the end, have you tried to fit two of them in a 14+ street glide fairing?

Nice! Now where’s the 8” neo mid bass? Thanks Carlos!

Thanks for an excellent review of this new amp. Just one question. I have a 2021 RG Limited with a WHMM and XM module installed in the GTS head unit. Will those add-ons make the installation of this amp more challenging than it already is? Thanks again and keep up the great work!

Do you have any videos showing how you wire and mount these amplifiers to the hard saddlebags?

Now what I wanna know is sonically is this amp superior to the SD 800.4. SD has the size advantage and dare I say it, price advantage, but if the Hertz is sonically superior then that will change the game for me. I'm assuming there is a 2 channel and 1 channel coming out in the same chassis, maybe beefier PS?

Trying to figure out since I just got sx165 hertz for my 13sg if I should use that amp or the 2000watt version. Using alpine bt headunit

This is wild!

Hey Carlos Ramírez!!! Hello Friend! I have a 2019 Harley Davidson Ultra limited and I plan to mount two sx 165 neo speakers in the front and 2 sv 165 neo speakers in the tourpack and 2 sx 690 Neo speakers in the trunk (saddlebags). With a single Hertz SP4.900 amplifier, will it be adequate to move the entire set of speakers mentioned?

Hey Carlos could I use the amp as a 3 channel. Say use 1 channel for both tweets, and use 2 channels for the 6.5 sx165? Buddy of mine says they'll handle a lot more power than what they're rated for. I've been using hsk165 for years when it was never designed for mobile usage lol and pushing them with the small jl audio amp. Wanting to make it sound perfect this time around. Just got the sx165 speakers so wanting to install them along with the tweeters I already have mounted into the fairing and install a new undated amp

It says in the manual bridged use input 1 and 2 if I'm reading correctly,you said 1 and 3 can you clarify thank you

Hi , any idea or word when the sp1.900 is coming out?

Is there any adverse effects of using multiple power and ground wires that way rather than one larger wire ?

Question i have a ds18 4" speakers on pods. Which amp best for

Would you recommend this amp over 2 SD800s?

Can I use that in my 14 GMC Sierra?

how this compared to two SD 400 in your stage one kit?

Did you ever get two in a street glide ?

Just curious how 3 years is "Industry Leading" when Biketronics is "lifetime"? Also, where is this amp made?

Do you need load balance resistors for this amp on a 21 street glide special 1:47

Can that amp connect with Bluetooth? I got a road king special 2020 I got 4 hertz speakers. Looking To upgrade my amp n add some subs can you make this happen ?

Basically the same size as a 2400, 800.4 seems to be a more versatile amp for motorcycle.
