Here is all the changes on the V2 from V1-

Smaller Heatsink, more compact

Onboard Voltmeter

Shallower Depth power/ground inputs due to amplifier able to pull less current to achieve same output vs V1.

Rated for 104w more at 2ohm.

Rated for 68w more at 4ohm.

All power has now shifted from 12.6v rated to 14.4v rated.

(This means it pulls less current but is more like other amplifiers made in the world today.)

Also, by shifting the voltage up, the Operating range has now significantly widened.

V1- 11-14.4v Over 14.4v clipped, could pop the FETs.

V2- 10-16v. No more worries about playing outside of suggested voltage range.

Input Sensitivity has dropped 30mV for more sensitive electronics to input signal into amplifier.

SNR has increased by 5dB to 95dB

Frequency Response WAS 5Hz - 15KHz, now it's 10Hz - 8KHz. This allows more controlled response than previous design.

We have already tested FR and posted results all over the internet and it's a LOT better for subwoofer use.

Crossover changes-

HPF- Was 5 - 50Hz, now it's 10 - 80Hz

LPF- Was 50Hz - 15KHz, now it's 80Hz - 8KHz

Efficiency has increased by 1% to 77% at 1ohm

Protection system has greatly improved! It now consists of-

Low Voltage

High Voltage

Shorted AC Output

Low Impedance

Thermal Protection

Excessive THD Output

Power Supply has widened to- 9vDC - 16vDC

Average Current draw clip-free has dropped from 431A to 360A due to upping rated power DC Voltage.

Weight has dropped 1.6 lbs.

Length has been shorted by 4.1"

Amplifier now has both Stereo Inputs and Outputs. V1 only had Inputs.

And the MAP price on initial release had dropped.

V1 was $888.

V2 was $790.

I say was because Brazil is greatly effected weekly by exchange rates. Taramp's will evaluate when exchange rates get extreme enough to change import pricing throughout the year.

If the price shift is enough, all other pricing is changed to such as MAP.

We try and prevent these changes as much as possible but if forced to, then we will.

Right now, MAP for HD8000 V2 is around $999.

We havent changed our MAP as it's still around $800 but we have stopped selling them to Dealers until we deplete the inventory in preparation for the pricing shift.

I run two v1 daily wired each at 1ohm rising into mid 2's voltage stays around 13.8. I usually play with clip light at a light yellow never red and have had no issues. The v2 should be a tank for daily just don't wire below rated

Oh but you can now, //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Certain restrictions of course. Either low impedance or higher voltage, or of course just keep it normal.

But if you are itching to get the most possible output power living on the edge.. pick one.. lower impedance or higher voltage.. both will get you high power, but higher voltage still is king for the highest output power.

What would be considered high voltage? And .5 daily would be pushing it right?

consider the bass 12k if you want half ohm daily.

We know the bass 12k can handle some low ohms.

The new 8k, 10k and 15k all share the same potential for the bass 12k but just hasnt been tested equally.

If you decide to wire to 0.5ohm.. make sure it really is that and not 0.35ohm.

Second, when wired that low, do not clip or allow the dc voltage under max load exceed ~13vDC. Pretty easy to do.

The other approach is high voltage. If running over 15vDC sustainable, keep your reactive impedance above 1.5ohms.

15.5v and higher, try and keep it above 1.8ohms. You see this is much easier controlled if using this information for burping.

Got any clue if taramps is working on anything new for the next bass season?

I cant say what but they are revising and releasing all new products over the next 2-3 years.

This is the current agenda.

The goal is to exceed not just the brazilian market but to take on the US market or korean and chinese amplifiers in both Low and High voltage models.

As a distributor and as a customer, i personally believe everyone in every country that has access to Taramp's should be thanking them for their efforts in what they are doing.

Everyone has to remember they are not just a brand, they are a buildhouse and those of us who do businesses with buildhouses know if you want something changed from the original schematic, most buildhouses will want about $30-100,000 PER item to make that happen.

Lucky for us, this buildhouse, Taramp's, branded their own designs.

This is good because if we complain about something, it will get fixed.

Over the last 3 years, we ( a collection of technicians, distributors, customers, and team supporters) have all came together and submitted massive changes that need to be done.

After several months of conversations, this current agenda has finally been started.

If you look back a few months ago, it first started with the release of the new T40 and T60k HV amps. Not normal for our market but new implementations started there.

Then.. it trickled down to the HD15000 and HD8000 v2 being released and everything that has happened since then which is MANY revisions to current products and new products such as the Bass 12k, Bass 400, TS-2000x4 and T150k HV.

We as a community of car audio enthusiasts to have Taramp's on our side to be influenced by what it takes to make change for the better.

I'd say stick around! IT's only going to get better from here, //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
