I had no problems installing to my custom box. It is powering 3 12" Kicker L7's at 1.39 ohms. I already had 1/0 ofc power wire with 2 battery's in a 2007 suburban. To date this is the loudest system I have ever had. Every person that I had sit in the vehicle could not believe how load it was. So a really great amp. The con is going to be the remote bass knob. This knob is very cheap. Mine was completely destroyed with the knob coming out of the housing. The bass knob was replaced by seller through amazon and received it very promptly. The knob I received was this one https://www.amazon.com/gp/product/B07J2QXBB2/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 I have verified that it will work with the original wire or the wire that comes with the aftermarket knob. I am getting some feed back from the amp to the subwoofers while the volume is completely turned down. It seems to only be noticeable when driving so will need to narrow it down. The amp before this was a 1500 watt Kicker and had zero bass noise when volume off. If your going to use a bass knob buy one while your ordering this amp. would definetaly purchase this amp again.

Killed my 1000 watt 10 yr old Niche sub. Lol. I have a sundown U2-D4 1500Rms coming in today. Waiting to put that in. Make sure the REM output is more than adequate when wiring this. I was using 5 vlts and was running hot and cutting on and off before i replaced it. Works fine now til i blew my old sub. Make sure to turn down gain/bass lv before power. Highly recommended. More than enough power for a single sub aplication or dual lower rms subs. Update: i had this for about 10 months now and its still working outstanding. Original subs are the sundown u2 d4 and replaced it with the d2 so i can wire at 1omhs. What a difference!! I thought it was loud before but its just rediculous now. Not even turn half way up and my car just shakes when the booms hits. Make sure to replace battery and use 0 gage on your wiring. Yellow top is what im using.

I have bought several xtr amps .It makes the power for sure. Small footprint at this power level. 9 x 14 x 2.5. Fits easily in a car. Few issues - the led power light will stop working in 2 weeks. This model in particular squeals (inside the amp itself, not thru the speakers) at initial turn on for about a minute if the ambient temperature is below 40degrees. If you live in Florida it will never happen. Hopefully thats all it is and wont evolve into a bigger problem. Its been almost a month with no further issues. Fingers crossed. Monster clean power tho. Update* two years later still working well. I live in Florida now and it doesn't squeal anymore lol.

bought this am about 3 months ago and its worth it.. but it was out of stock . so he sent me a xtr2500 amp instead!! woot woot!! (2500.1d) 1050 at 4 ohms-1600 at 2 ohm and 2500 at 1 ohm, all at 12.5 volts! nice man very nice!! i guess i caught him at the right time ot get one. i cant find that model number anywhere on the net but i have one!! its not the old one it is the xtr like the one shown. he said it was a newer model. its not on orions website also. ( its never updated anyhow) i have some xtr pro subs from orion and you only see the regular xtr now. not the pro. but anyhow. its a nice amp. buy it. sound is good and clean . the bass nob is NOT a bass knob, its a remote gain control.even better! adjustable phase for subs not a 0-180 switch bass boost works like it should.. i like that its rated at 12.5 volt and it comes with a birth sheet . mine is under the specs on the box but trust me . when u have 1550 watts at 12 volts as opposed to at 14.4, at 2 ohms. you arent complaining . most amps barely do rated at 14.4 much less being real wattage.. end result is i like it .. id buy it again if i needed too.

This is an excellent and well-made amp. I bought this amp to replace an old Orion HCCA-D2400 and I couldn't be happier. This amp is more powerful and more controlled than the old HCCA was. Bass now seems punchy and tighter, less boomy. It is driving a single American Bass XFL 10 D2 @ 1 ohm. I can now hear the bass much better at my normal low volumes, so it seems the power is more linear. This amp is more powerful yet smaller than the old HCCA which I was very happy with. For me the negatives are minor. The plastic end caps must be removed to effectively get to the set screws for wire connections as well as the mounting tabs, but in my case, due to the way my amp is mounted, I could not put them back on after mounting the amp. This amp does not have as much fine tuning as the old HCCA did, such as the subsonic filter, it is either off or on @25 Hz. There are three lights on the top of this amp including power, protection, and thermal protection, however as nice as that is, the lights are not labeled and must be memorized in order to diagnose without the manual handy.

I love a good deal. My Rockford Fosgate 1500 BD stopped working. I decided to buy a new amp vs repairing. I came across a Dyno test Video for this amp done by YOUTUBE USER "BigDWiz". I was sold... The amp arrived and I installed using the same 4 gauge(Stinger OFC) as I used with my Rockford Fosgate 1500BD..... BIG MISTAKE, the 4 gauge wire was not receiving or dispersing the power efficiently. Amp would get HOT enough to Fry Bacon and Eggs on...needless to say, I ordered a pair of dual 1/0 gauge input block terminals to install on amp for power and ground. Once THIS BABY had all the juice it needed.....Pounds relentlessly for Hours and no longer gets warm at all. This ORION XTR2500.1Dz is everything I needed!! I have four 12" MTX fpr shallow mount subs in a custom down-fire box wired down to 2ohms in a 2015 F150 SuperCrew. This amp is giving them about 2200 rms @ 2ohms. I have the amp gain set to 1/4. PLENTY OF QUALITY POWER!! aWESOME DEAL HERE!! My Electrical * 250amp Alternator(Stock for F150(V8) * XS POWER D3400 Under Hood and XS POWER D680 in rear * 1/0 BIG THREE UPGRADE and ADDITIONAL 1/0 gauge Ground from front Battery to vehicle body * 1/0 Stinger OFC wire throughout
