[@chrissmith2277]

Thank you Big D for the review of the cosmos audio 2000.5 I have been running mine in my truck almost 2 years and have been blown away by its power and clarity. It pushes my for Cosmo's eights and my mids and highs front-rear without a problem. Can't wait to see more videos on your channel.

It's not cheap but if it can run your whole system that would be beneficial.

[@wal]

It’s true

[@KB-1976]

@@wal id rather have a board, even smaller, running 2 chans, and multiple, in a full system, but, to each their own.

[@JS-wc4xs]

This amp draws 360amps at its peak, you would need at least a secondary battery and preferably a high output alternator too. For someone trying to save space by using a 5 channel amp, it's requiring a lot more space overall. The amps footprint is way too big for the guts inside. I'd b concerned with longevity (especially with that whine at the end of the video), 1/0 gauge wire is bare minimum for such a power hungry amplifier. I'm not ripping on 5 channel amps (I have a JL 900.5), I'm just concerned about how long will all that power continue. I'd like to see a 2 year look back on how much power the amp still puts out (after 2 full years of full time usage). I've had my 900.5 installed for well over 4 years, and it still bumps hard. It's quality, built like a tank, small, and doesn't suck too much power which is great if going sleeper under the hood or in the cargo area.

@@KB-1976 and with dirty power?

[@Mr.NpK143]

@@JS-wc4xs this is a high quality product. It's warranty matches that of Jl Audio. And the components are just as impressive if not in my opinion better. But this is not a Cosmos vs JL. It's just Cosmos is what it is. A quality product 👌

[@matpatte]

Wow this is a massively impressive 5-channel. Actually has enough power on channel 5 to push some serious volume. And the fact that it has bandpass on the 1-4 channels built in so you can potentially avoid needing a DSP.

[@CarAudioObsessions]

Yep I came across this video after seeing the company demo car with the 32" sub and full Cosmos Audio setup on it. I went to their site to check out their product line and I liked what I saw. There are a couple of interesting subs and I also immediately noticed the Bandpass ability being present when I was checking it the 100.4 and 200.4 four channel amps. Just wondering now if they are CEA2006/2031 compliant or if all their amps actually do rated or better. They don't see like a company that does the Boss/,Pyramid ratings.

[@Bassotronics]

I was waiting to see this brand tested since the headquarters is 2 hours away from me.

[@VochoTalacha]

800 bucks is waay too much... then again, we're talking about an amp that can make over 1000 watts on the sub channel. Thanks for the video Big D

[@CarAudioObsessions]

@@Az56818 yep for less than 800 bucks I can get a well known quality brand 4 channel and a separate monoblock that makes around thay power. They are a new company, they should be starting out with amps and stuff under the $400 or even $300 price point and then let word of mouth advertising do it's job once they build a reputation and customer base, they can go into the bigger and more powerful amps and command steeper prices because they will have established trust that the person will be getting a quality product for their money.

[@suprola7961]

I was just looking at these at a dealer in Virginia. Never seen this brand anywhere else. I will add that they make Cosmo branded wire too. It’s what I’m using to drive my setup. Pretty good stuff!

[@MrChuckmason]

I enjoy watching your videos. I know a little about what goes in to the construction of these amps and that one may put down some power but at $800.00 don't expect it to last very long. Its way over priced. Keep up the great work.

[@CarAudioObsessions]

Overpriced for an unknown company and looks super lack luster inside. I was like where's the beef? When he opened the back cover. I don't see no 800 bucks. Didn't even have high end caps etc that I noticed. Starting out like this with those prices I'd be surprised if the company lasts. Start off making less expensive price point stuff, build good quality stuff for the money and let work of mouth get around and then the company can venture into the 800 and 1000$ slots. I'd sooner give my 800 bucks to a much more well known company, even if I ended up with less power. Although for 800 I can buy a 4 channel and a monoblock and have about the same power and likely better quality and sound. Not many people be buying $3500 subs that cost $3200. Niche market for that kind of stuff and putting R and D money time and effort into those types of products when a company is in its relative infancy is how they end up not lasting long. Hope I'm wrong and they make it but I don't know many people that would drop 800 bucks on an unknown brand. 🤔

[@JeremyBreeden89]

I’ve been using cosmos audio amps for years and it’s crazy to me how very few people seem to know of them or run their equipment. I have three vehicles and in two of them I run a cosmos audio 2 channel for my components and a cosmos audio mono for my sub and then in my other car I run a 5 channel but mine is much smaller than this one. Anytime someone asks me to recommend them an amplifier, I always suggest Cosmos Audio. I’ve yet to find one of their amps that doesn’t easily reach its RMS power and much more. I guess living only 20 minutes from a Cosmos Audio store has made me like them even more lol.

[@MrArtMorris]

I hear two different high-pitch squeaky tones plus the fan noise coming out of the amp. At 16:27 the lower pitched squeaky noise stops, but not the higher one. You won't notice it with all the power the amp is putting out.

[@dlcarburetor]

Like the bits added at the end of the video

[@20smgreen]

D, for a more real world test, when you test the 4 channels at 4 ohms, a most will run then at that but on the sub channel you should run it at either 2 ohm or its 1 ohm limit which is how most people will run it. Then we can see the real world output of those 4chs @ 4 ohms. I'm shocked at what's not inside it! My Audison LRx5.1k is roughly the same size and it is cram packed. We need to get either one of the Audison 5.1k amps for you to test. If I wasn't using mine I'd send it to you.

You would think with the lack of components inside the price would be much lower as compared to the AudioControl, it also makes me wonder if there is all that need for the extra components if this amp can do the same job without using them.

[@Siryn]

After the squeaky (90's modem sound) there is a very high pitched whine around 16Khz+ that never goes away and it's not the fan. I can actually hear above that and slightly above 20K and it hurts sometimes. As a child back in the 80's I could not go into certain stores because they used machines that gave off that high pitched noise and it hurt to the point of making me nauseous. That ability never really went away.

[@gregblau8082]

Derek: Ya boi! Me: For $800 base price this thing better make it's rated power and then some. I bought an Orion HCCA SPLX 3k watt amp for the same price. This isn't exactly like buying a Maxxsonics amp...lmao Thanks for reviewing this amp BigD!

[@markgreene9330]

Nice amp big D , Great video ...keep them coming ...You the man ....

[@wal]

Flowing like Eminem rhymes

[@TheDudeRc]

Kind of amazing it made that much power when my 75x4 has four 10,000 microfarad caps and four 2200s on the input filters. That means all 3 of my amps making the same power have a dozen 10,000uF and 21 2200uF filters and seven coils! That amp really seems to be making the most out of what it has! Wonder what the THD is and if it really is 85 or better S/N?

[@shemarwilliam4369]

From my experience as an engineer, it's possible that the switching frequency from one of the switching systems are using frequencies or producing harmonics within the audible range of humans

[@car2069]

I drive past this place everyday and even though it put the power down, I’ll stick with traditional brands I know and trust (JL, Rockford, Kicker). The cosmos stuff came out with pricing really low and then quickly shot up, to the point of this amp costing as much as audiocontrol or another brand that might be a bit less power but has the history to backup its quality. This looked like a $90 amp inside. Nothing to justify the price.

[@SPUNLEE]

The price is actually cheap per watt and how many amps you would have to buy to equal this. Real ? is longevity. Great Vid BIG D

[@fleuriejeanpierre]

Did very good with the numbers and very flexible but is it efficient or will it go into protect every 10 minutes? If not it's worth the money for someone who wants one Amp for a pickup truck application with plenty power or bump as you say....

[@jonathanjackson1962]

Seems like they could have made a compact very powerful 5 channel amp with the wasted board space, but opted for the size factor. The would not appeal to someone trying to build a powerful system where space is at a premium.

[@marcussmart3275]

It would overheat I think. An amp with this kind of current going through it is gonna pump some heat out. Bigger board makes more distance between heat sensitive components also makes for a bigger housing bigger heat sink.

Something about this amp is giving me hesitation. Long before you opened it and it lost power with a higher load (Lower Ohm) I raised an eyebrow. This amp seems to be living on the edge with the power supply side. I've never had good luck or results with amps that nosedive with higher current demands. When you opened it up, my suspicion was confirmed. Big D I know you are trying to give this amp the benefit of the doubt and be fair as possible and I can appreciate that...but I think you know what I'm talking about here as well.

People are saying the amp is priced high but if you price the average Korean 2000watt amp and 4 channel amplifier you are gonna spend the same, but the difference here is you are getting better than most and this amo is in the class of the top 5, AND I REST MY CASE.

Could you ever try products from Steg and Awave? They look very high quality apartment and especially competitive compared to other brands.

[@CarAudioObsessions]

I do agree it's decently impressive however the clip light not working makes me wonder of its even really functional or just there to look cool or possibly justify the high price.... imo it's too high for a relatively unknown brand, regardless of power output. For $800USD there's alot of amps I could buy that are much more well known. May not find a more well known 5 channel with a very powerful sub channel, however for that money I could easily buy a 4 channel and a monoblock to cover sub duty. Also, for $800 I would expect it to look a little beefier and more robust inside. It looks kinda cheap with the cover off, although I appreciate the fact it's a Korean board design.
