Great sound

Very powerful. Clean sound as the highs have more detail than the clarion xc1410 I was using.

Great amp

I switched from the Precision Power ION PPI i520.4 to the Pioneer GM-D8704 and the difference in quality is huge, while the PPI produces it rated power l, the sound quality isn’t very good compared to the Pioneer amp, I am truly impressed. I would recommend the Pioneer amp to anyone.

Por $150 dolares que pague por este amp gm-d8704 la verdad es que estoy sorprendido. simplemente wow! Lo tengo conectado a unos 6x9 componentes infinity de 100w rms y unos 6.5 componentes pioneer de 80w rms, con otro amp pioneer gm-d8701 un woofer kicker de 150w rms, un stereo kenwood excelon x305 con salidas de RCA de 5v y obtuve un sistema de sonido con exelente calidad de audio, no gaste cientos de dolares y suena duro y claro. si estas buscando algo bueno, bonito y barato? este es el amplificador para ti.

Worth every penny.

At only 170 you definitely get the bang for your buck. On top of that you get incredible sound quality and performance.
