Best amp for 3 X15s wired at 1.3 ohms?

Get the 8k. I've got a long time box customer of mine who I've done crazy stuff for. He's gonna put 2 of the salt 8k's on 4 18's, or so it's planned as of now. From what I've seen, those amps do work. He's very happy with his salt 8k. He's got it on a pair of 3000w or so woofers.
 
That's a tough one. I'm not a huge fan of massive mono blocks. My personal opinion is they tend to be less reliable and more expensive to repair. I myself would do 3 smaller amps gain matched.

3 SIA3500s
3 SQ Q2200s
3 CAB 2200s.

It's gotta wire up well. Is there 2 4500's he could safely run at 1.33? I ran my 2 eD 9.1's strapped at 1.4 ohm (1.4 ohm DC subs). Only cut out when I tried to play like 25 hz and punches would happen.

Also a possibility. Yeah my two 2200s at .5 strapped would protect if I did a high hz burp as well.

Both very true, but I do not like gain matching and would trade the reliability (to a point) for convenience there. Stephen Mantz used to always insist that the far east class D circuit designs were really rock solid and reliable up to about 2000-2200W and beyond that you're rolling the dice every time you power it up. This has been consistent with my experience as well.

Didn't that guy burn all his vendors and authorized repair guys then disappear?

The only full bridge I've had was the SFB8000, it fried itself
So that's why you have 2 year warranty. They're cheap enough you can just buy a spare for when one is out for warranty repair or just throw them away when they break after that. Repair on Korean 8K half bridge boards can range from 350-900$

I finally got my Soundigital 12K back installed and IMO it performs better than the SFB. Dollar per watt Soundigital is significantly more than Sunown's Chinese clones though so not sure if they're worth MSRP.

They had problems trying to get a full bridge line going, but they are still open. I think the one partner who knew nothing about car audio finally left the company. They're doing a pre-order thing right now. My second choice would be the Taramps MD12K at one ohm.
 
Thank you all for the input! And I suppose with the money you save you really can just buy 2 of the same amp.. I have been looking at the SounDigital 12k, it looks great and seems to perform great but again the MSRP is pretty high for a full bridge. Also the wolfram 9k is on my list bit have heard that they may be going out of business (even though I've gotten emails for the AW 9K pre order

So still taking people's money. Have they taken care of their vendors and warranty centers on the money/product they owe? Why would you send people like that your money when the same boards can be bought for just a small price premium from companies that you know will be around next year to back things up?

Yes and yes. I don't like the fit and finish or the single inputs but it is a beast and is super quiet compared to the Sundowns. I bought mine refurb for a very good price and would definitely snap up a matching one if I saw refurb or used <1000$

Like Fi?

Fi isn't going out of business any time soon. They have quit taking orders in order to catch up because of how far behind they are. That says something that people want their products as it is quality stuff. Everyone knows when ordering Fi subwoofers you expect at least 45 days if not longer because of how small of an operation they are. At least they have been around many years with tons of customers vs Wolfram which hasn't and is taking preorders when they still owe a ton of amplifiers to people not even including the dealers not too mention the money they owe to everyone. I wouldn't trust one of their amplifiers anymore let alone trying to get customer service of any kind.

Have an Xli 2500 as a sub amp in the music room, overkill for sure, never overheats, never skips a beat.
