I have a chance to pick up a Ultra Linear UL1500X for $50 bucks and was wondering if it was a good amp and price? It would be used to replace my Earthquake PH120.2. to run 2 Earthquake dbx10 10 subs.

Here are the specs:

1500W Class X Mono Block Amplifier

12-17V Power Input

0.2-8V RCA Input Voltage

Frequency Response 10 Hz - 350 Hz

Short / Overload / Thermal Protection

Bridgeable with second Class X amplifier

24dB Variable Subsonic Filter

24dB Variable Low Pass Filter

0-18dB Variable Bass Boost

Remote Gain Control Module

RCA Line Output

RMS Power @ 14.4V DC

1 x 500W @ 4 Ohm

1 x 750W @ 2 Ohm

1 x 1000W @ 1 Ohm

RMS Power @ 17V DC

1 x 750W @ 4 Ohm

1 x 1000W @ 2 Ohm

1 x 1500W @ 1 Ohm

I think for 50 dollars you cant go wrong.

Thanks, I know I can't go wrong for $50 but is the amp any good? I never used Ultra brand before and was looking for someone that maybe used this amp before.

Do search on the internet and see what you find.

I did and didn't find much about it.

Ultra has seemed to have a mixed track record. They came on really hot two years ago, again another one of these better then all others based on some of the hype, but when some people started paying attention and using the products themselves, things changed a little. They had some big traffic on DIYma for a few months, and now there is almost no mention of them anywhere. We almost hosted the Ultra forum here on SSA, but then with the issues some customers had with the owner, right from the get go, we decided not to. From what I remember, supposedly the amps share a lot of bits from an ARC design.

I picked up the UL1500X plugged it in and up in smoke. I hurried up and unplugged it as fast as I could. I took it in the house and took the top cover off and found this.

Guess I should of known better that that.

That is a different Ultra.

Ultra Linear I believe is another Pyramid-esque brand.

Ahh yes, sorry. Please disregard my earlier post.
