In reply to kutarescu/ Full review. NDX5500

To the guy that says this is not one Ohm stable. First off nothing is short-circuited, 1 ohm has a very low resistance yes, but amps burn up because improper input voltage. I have benched this amp with clamps,volt meter, and a oscilloscope, at 1 ohm right before clipping was 1,891 watts. This is a sub 2K watt amplifier, for 170 bucks that's not bad.
You will NOT get the labeled 5500 MAX! That's a marketing gimmick.
This amp is stable at 1 ohm. Do not use BassBoost as it's a db gain @ 45 ish hertz. Adjust the gain properly, its not a volume nob.. its there to match your head unit's output voltage most head units have there output voltage labeled in the manual.
If you set this amp up right it does the job just expect a sub 2K watt amp. I have mine hooked up to a 18″ PSI Platform 2 @1 ohm.

1 ohm stable

They say 1 ohm. NOT STABLE, idiots. I really don't know how can you manage burning amps. I think you are a bit parallel with car audio technique. Don't over range the gain (it isn't a VOLUME, it's a compensator). Bass boost is in about an 18dB range. Again, for compensation. In case you need to keep bass much lower in your head unit without HPF, so long and so forth. If you want 1 ohm (stupidity) buy competition amps. At 1 ohm, you may consider your final amplifier module short-circuited, but it still has to work a bit harder even for BRANDS (eg kicker, cerwin-vega, GZ, etc.).

Awesome Product

...I love boss products. I have never had any problems with it. This amp is just way awesome you don't have too spend top dollar amounts to have a good system. If you know what you are doing and hook it up right you will never have a problem. Boss products are just by far the best and I will continue to buy them and always recommend them. I look forward to buying more in the future great amp a must buy...

Broke under a month!!!

i would recommend this amp because of the power. Pushed my two 12 inch alpines type x well, but the amp broke under a month of useage. Thank God i have warranty =D otherwise it wouldn't have been worth it.

Boss NXD5500

This amplifier is a good buy. You get a lot of power for a good price. Running it at 1 ohm and it seems to get a little warm but haven't run into any other issues yet.

Hmm

Got this amp, shipping was nice and quick, had it running for less than 36 hours and it has stopped working.

Boo NXD5500 Amplifier

This amplifier is awesome the price is great and the power is awesome, it's a well built amplifier. Doesn't over heat. I ran it for 3 hours and it didn't over heat. I have it pushing 2 audio dynamics 2500 Watts a piece and its driving them with no problem. My bass is round and solid I would recommend anyone to try these amplifiers.

Powering single 12"

Single 12" MD Sound 12-12175 into 1.5cuft sealed custom fiberglass box. Dual 2ohm. Running parallel for 1ohm load to amp. 3farad capacitor.

Seat-of-pants-meter is telling me an honest 1000-1500wrms or so, maybe more. Can bottom out the subwoofer at higher power. Haven't clamped the output so just guessing. Great bang for your buck.

all boss audio is cheap and only for low usage

people with boss subs and amps always blow them if you try and use them to there potential. i seen people with 12" boss subs barely even hits and the amp was pretty big but i dont believe it was able to push out what it says it could.. I got 2 15 l7's 10 cubic foot box and 2500 watt kicker amp that **** bumps. kicker all the way. Nothing wrong with alpine or memphis audio. DC are good but expensive.
