Okay

Buen producto funciona bien y mejoró el sonido de mi auto de agencia sin duda excelente opción a un precio súper bajísimo

The Amp earth's itself through the RCA cable and cause huge feed back, even with a ground loop isolator! Tryed multiple Earth points and different RCA cables as wanted to be as fair as possible when using this product but you CANNOT get the noise to stop. APPARENTLY returns are unavailable will be raising a complaint

Funktioniert fast tadellos, jedoch wird bei laufendem Motor die Oberwelligkeit des Generators nicht weiter geglättet und mann nimmt dieses als Surren in den Lautsprechern wahr. Dieses Surren könnte man entgegenwirken wenn man paralel zu den Plus- und Minusanschlusses einen Kondensator betreibt. Die Einstellpotis funktionieren reibungslos.

***UPDATE 8/4/18*** I went mudding a week ago and accidentally sank my jeep in a pond 🙃 Completely flooded the floor of my interior and soaked the amp, luckily it was off. A couple days later I ripped the entire interior out and washed it out really good, like literally washed the inside of my jeep with a hose. I figured the amp had already been soaked what more harm could I do. Got everything back together after drying out, fired up the jeep, turned the stereo on and BAM! Perfect sound quality. If it can get soaked twice and still work I think that says something. *end of update* Did you know, that running your power lead in close proximity to your audio cables can cause loss of sound clarity, distortion, and you guessed it, alternator whine?! I’ve had to fix plenty of botched installs due to this. I did a little test and ran my audio cables directly next to my 4g power lead going to both my amps. Heavy whine and almost no signal clarity. Re routed my cables to run on the opposite side of my power lead and wow! Signal was clear, bassy, and no alternator whine. This amp is phenomenal and woke up the old Bose speakers I pulled out of a 2001 Pontiac GTP (2ohms at 50 watts RMS, give or take). I drive a Jeep Wrangler TJ and space is precious, so I can’t have big amps and fancy subs. This fit under my driver seat perfectly and cranks some serious audio to my speakers, even with the top down. Great price for a quality low budget system and I get lots of compliments from friends. GREAT AMP!!!

イコライザーは付いてないし、w数あってんの？って並にならない。これ買うくらいならアップガレージで中古買った方が全然良い。 安いとはいえ酷い。 音質「ノイズすごい」 安さ「値段同等」 取り敢えず2度と買う事は無い。
