I've had people looking for motorcycle audio a lot lately. This looks perfect for that. Nice and compact but puts out real power.

I'm currently using this amplifier on my bicycle paired with 2 Faital Pro 4" Neo speakers and I really like it. Fits right under the seat and is almost invisible.

I don't have a car but I love your channel Great work bro I really enjoy watching your videos Love from Boston ✌️

excellent test kit I am looking for one this small for my car without space in your opinion which is better this Stetsom IR 400.4 or the Taramps TS400X4 or any recommendation of a mini 4 channel 4 ohms from another brand thanks love

Hi, thanks for share and all the job done, I'm looking for a descent amp, not looking for super high volume but sound quality, ¿which one do you recommend?

Hey Big D. what would you recommend for good Bluetooth 4 channel 200ish watts mini amplifier? Something about 50 bucks or cheaper. Just sticking it in a beater I just don't want to mess with a head unit.

Awesome video Derrick

You literally just made that up. Why would a tweeter amp be a 4 channel... Besides it says that nowhere, not on any sales site nor their original site. Would it be good for tweeters? Yes. Is it a tweeter amp by definition? No. Stop making up things trying to sound smart.

@bigbobbrown8635

Yeah. I sale them and install them. They can play small speakers but do better on tweeters.

I would love to see you test the crescendo s4. There’s not an actual power rating, the box says 800rms but their website says 880rms. I have one and it sounds amazing, just curious what such a small amp is capable of. It keeps up with my twisted sounds 3.5k at a half ohm, it’s pretty impressive!!

whats up with the SA6.5? looks like the spider pack isnt glued down right or something.

I'm building an old school boombox, 4 ohm with 10" woofers, similar to the Bumpboxx Freestyle, and I'm look for a decent amp to put in it; what would you recommend?

Howya doing Dee is it possible for you to Dyno the soundstream 6000.1

I have a dumb question.. I am thinking about using this to power my door speakers they are 60w RMS at 4ohms, I see in the spec sheet that it can do 60w x 4 @4ohms. how would I wire that and get 4 channels to work properly?

What would be a good amp to run in a motorcycle bagger aspect i have 2 ds18 zv6.5 plan on adding more

A large number of Amps have power terminals too close. I use insulated ferrules and heat shrink to prevent any shorting. Also stable mounting goes a long way too.

Your testing is the closest you can get to real World .#respect

@@sergiocuevas7589 I was looking at the 400×4 rf as well. It's definitely in my top 10 of choices. I know I want more power than 100×4 because I plan to run as many speakers as possible from whatever 4 channel I end up with. I'm replacing a 350 watt rms dual 4 channel , so I want to step it up quote a few notches lol. But i am also trying to stay under 200 and even under 175 if possible. So I'm looking at soundqubed s100-4 as my top pick and I'm basically stuck between that amp or skar rp150.4 or the pioneer gm8604. Right now I'm leaning towards none of the above and going out on a limb for the massive audio blade 1500.4 amplifier. I've had good luck with massive audio product and that amp looks very nice and claims great ratings and features. But I know nothing about it except what the website says. So I may just try it. It claims 240×4 @2ohms. Even if it doesn't quite get that much power it could end up being very nice. $119.00 bucks man it may be a gem lol

@sergiocuevas7589

Massive clean power for full range is not cheap. You gotta compromise sound quality for power in a class D. A class A/B will ALWAYS sound cleaner than D, but they are bigger in size. Throw a $200 budget cap and you’re stretched out even thinner. For my SQL truck I’m running a T600-4 class A/B amp for 4 T2 6.5 components and the amp runs them with ease. For my SQ truck I have the Zapco sq (which starts at $200) running Kappa components and the sound is audiophile grade BUT half as loud as the t600-4.

@@sergiocuevas7589 the amp I'm talking about is class a/b full range with bandpass option and cea 2006 compliant rating and only 119 bucks and it's loaded with all sorts of filtering features ect. It's definitely between the pioneer, the soundqubed and the massive audio blade amp. I'll prob go with the massive audio because it has alot of power and I'm sure it will sound good. 240×4 @2ohms is plenty of power to push a few tweeters and coaxial or mid range speakers. Anything will be a upgrade to what I'm using now for my highs and mids. I can't complain now at all either. My shit is crazy loud.

can you do a dyno test of the timpano 800.4??

Even though the wires were connected incorrectly, I still see a practical use for this amp. It can be used as a stealth amp for those who have an aftermarket head unit, but still rocking the stock "special" speakers (i.e. Bose) and want just a tad more power going to them in conjunction with the stock "amp". This will be especially for those who have 90s/00s Nissan & Infiniti cars with those Bose setups.

To be fair, Stetsom states those power ratings at 2 ohms. They openly rate the amp at 45W RMS @ 4 ohms. It's actually not bad for the price.

At 4:51 are you sure you have it bridged properly? Looks like you have both positives connected for bridged mode, while it is showing Left + Right - as the bridge function/connections! Not one to question your knowledge, but it looks like you are using the Left +, Right + to bridge two channels! Just looked down and well, someone noticed it as well!
