this is class a/b 125x4 , its powering four RECOIL MS694P 6X9-Inch Midrange Pro Audio Car Speakers that have RECOIL BB-69 Bass Blockers . then i have a vevor 3000 that power 4 ampere aa-2.75 15s in a 2012 dodge grand caravan with 250amp alternator, 1/0 power leads and a 200ah agm battery . dirt cheap loud and lasts if you give it the power it needs

A good buy!

Es mucho Mejor de lo que me imaginé

Very happy with the amplifier sound great and runs cool I'm running two 12inch subs and 2 mids and it sounds amazing

Good news this is incredibly compact not much wider than a hand spread, it is also quite efficient. However amp does idle quite warm with no load[left on for an hour , no audio and was quite warm] not sure how hot it would get on a long drive fully loaded. I did bench test this amp and it sorta does rated power , depending on how you interpret there ratings manual claims 272x4 . In reality that is likely meant to be 272/4 = 68w a channel at 4 ohms, in testing I get 72-85 watts . at 2 ohms they claim 400x4@2 in reality it is 144-171 watts x4 exceeding the 100 watt x 4 , however when fully loaded[all channel driven might be a bit closer to 100 a channel Bridge is is 196-216 watts at 4 ohms They claim 800x2 that is clearly way off Fuses are 2x20 aka 40 amp , which always gives a good estimate of about 400 . . for the money and size this thing is is pretty cool. . What i do not like is this amp clips very nastily [see picture] . Also the High Frequency switching from the class D topology is present on O scope. I did test this amp with actual audio and it not audible , but then again it wouldnt be since it is so high frequency 80-150khz the excess HF noise readable on the O scope is concerning. . This was an accidental order so will be returning [thought it would be needed for an install that we were doing] My Final thought are IF i was no aware of the HF noise i think i would really like it, especially as it is so small it should fit behind most head units and under most seats. . There will be a video on youtube from the test, Just search the model number of the amp MXD400.4

Buono

Funciona perfectamente también es bastante menos potente que una 4 canales que tengo de 4x60w a 4ohms esta anuncia 200w a 4ohms. (Real tendrá 40wrms a 4ohms es bastante menos potente que la que estaba usando de hecho para que suene igual los altavoces que en la antigua tengo que poner la perilla de ganancia a 3/4 cuando la otra estába a menos de la mitad en la antigua) lo único que no me ha gustado que no me di cuenta al comprarlo que no trae conexión atornillada de salidas para altavoces ya previamente amplificados por dicho amplificador en su lugar trae una ficha endeble con las salidas estéreo por canal +/- ahí he puesto unas fichas empalme para conectar los cables de altavoces. Por lo demás bien por lo que cuesta no se puede pedir más además de lo pequeña que es Vane en la palma de la mano

Unreasonable. Vevor's quality products do not line up with their customer service. I've purchased several products from Vevor that I use today without issue. I have one product inquiry and request for a refund, I'm getting pushed around back and forward by an AI loop. Not a single human person is stepping in, Unreasonable.

Seems like a decent amo for the money but I had 2 if them sip without the pictured harness. Unfortunately this harness is required to connect your speakers.

Niet werkend. Blauwe powerled licht op bij aansluiting, and that's about it. Geen outputsignaal naar speakers.
