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...

Boss NXD5500

Big amp for a lot of bass and looks really nice.

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.

Boss NXD5500

Tons of power for the money. It pushed my two L7s decently, but I've sent it in under warranty twice now and it just broke again right after my warranty got done. It's a great amp if you baby it though.

boss amps

This amp is really good power per dollar.

Good amp if you know what you are doing.

I have done a TON of research and this amp IS 1 ohm stable but only if you can give it the power it needs. You can't run this amp without a "big 3" upgrade in your car or it will burn itself out when your stock wiring can't supply the needed power. It is good to run 1/0 gauge wire all the way back to the amp too(a 20 foot spool costs $80-100 because it's that important). Also, you will almost cartainly need a high output alternator and a deep cycle battery. I plan on buying this after I do my big 3 upgrade later this month. I will be pairing it up to 2 Boss AR12D subs. 2400W RMS total 4800W Peak will be my system.

BOSS NXD5500 VS Hifonics Brutus BRZ2100.1D

This is the best mono amp in the market! The RMS level almost identical to Hifonics Brutus BRZ2100.1D. In fact, BOSS NXD5500 is even more powerful.

good investment

I recommend this amp to anyone who wants more bang 4 there buck no bs.its a good product .it pushes my 6 kicker 12,s so try it u want b sorry.its too thumbs up in my book .I will buy another just because.so buy u one or two and get ahead of the game in your area.

Installed Correctly

All the 1 stars on durability leads me to believe the majority of people dont install this amp correctly. If you are going to have an amp this size you need to do the BIG 3. If you dont "YOU WILL" burn this amp up. This isnt an entry level 4 AWG wire from battery and done amp. You need the BIG 3. You need an extra battery. If not any amp this size burns up.

dont buy it.. pos

The amp sucks.. boss will not refund my mone. DONT BUY A BOSS... buy Hifonics.

I dont know about this one

Had this amp for about 2 weeks before burned out. It says it is 1 ohm stable but i dont think it is. Waste of money get a hifonics.

The BEST!

This is the most powerful amp I've ever owned. I've had it for 2 years now and still running hard.
