Tony´s test on SD8000 on 2 soloX 18"

[murilo 10+ year member]

I got so happy with this review made by Tony Hoffman, so decided to post here.

To explain: I made him a proposal, since he didnt know the brand: I said I would refund him if he thinks the amp is not good, so here is the review:

I just bought and installed a SounDigital SD8000 amp.

 

I thought I would share my experience. I have seen a lot of question about this amp and its ability to perform as it is rated. I believe this is because of the small size of the amps as well as the fact that it is a relatively new company.

 

Let me tell you, it performs even better than expected.

 

Unfortunately I didn’t get a lot of play time. One of my subs blew. The coil was making a bit of noise at the end of the last year, so it is no surprise to me, especially after putting that much power on them.

 

During the time I did get to play it I did notice a few things that surprised me. First was the sound of the amp, I must say (with limited play time) it sounds cleaner and tighter then the kicker amps I was using.

 

Secondly (not as surprising due to the fact that the SD is rated much higher) this amp completely out performs the pair of zx2500.1 amps. (I was also comparing the kicker amps with the car running to the SD8000 with the car off. I’m sure the extra couple volts I get with the car running will make it even more impressive.) From a rating standpoint there was no doubt the SD8000 would do this, but there is that visual aspect that leaves doubt.

 

Looking at the 2 kickers compared to the SD8000. It makes you think there is no way that an 18” long amp could out perform a combined 54” worth of amp in the kickers.

 

It took all of about 5 seconds to put that doubt to rest.

 

Now I must also say Murilo Alvares (International sales and after sales care) was great to deal with. He answered my many e-mails and phone calls about this amp quickly. Unlike many other companies I have dealt with he was able to answer my questions with out having to refer to “the tech dept."

 

From my experience it was some of the best customer service I have had.

 

I would definitely recommend this brand .

Hes posted numbers before, and people didnt believe the numbers. That was with the old version of the amp too. (it made less power)

prices seem a bit steep, well for me at least

Numbers with no proof might as well be no numbers at all. I'm eager to see how one of these performs but all the hype with nothing to back it up is making me dislike SD for the time being.

Mr. Alvares, you should have testing equipment on site right? Make a few videos: direct drop-ins with other popular SPL amps, voltage drops/output with clamp meter etc. to back up your claims.

The amp outputted 12970W in 1.7 ohms on a 16V install, the power was measured by Rip Rock team in Didsburry, Canada.

Their words:

this amp will do over rated power. In 16 volt system we got 148.3 ac volts, 87.4 ac amps, and drop to 15.08 volts so 12,961 watts.Start impedance was 0.5ohms. tested a SD8000D last weekend.Tested in a SS 5+ vehical( SPL Life's vehical). Db don also has tested this amp. Hard to believe yes, but it does what it says. Thanks for murilo for letting us test the amp out.

Electric team in Italy measured 164.5V and 80A in a 16V install also

I also posted a long time ago some tests done in Brazil, here at CA forum.
