  • Great for smaller vehicles
Great punch and frequency response. Clear and not muddy or boomy. Doesn't foof like a ported box, stays tight and covers the range. Goes well into 150 Hz for those bass tones and not just the kick drums. Heavy, solid enclosure. Not overwhelmingly loud, but these Kicker subs are supposed to have a long break-in period so I expect more volume after 50 hours. Fits my vehicle, that is priority number one along with the sound. I am happy with it for a little 8" woof. ... show more

  • Easy bass Best if you buy an amp with bass knob control
Buy these they sound like a 12” set!!!

  • 2nd Gen Rx350 perfect fit
For anyone with a 2006-2009 lexus rx350, this is the perfect fit for the spare jack under floorboard of the trunk. You just have to remove the scissor jack and the black plastic holder, then this fits it tightly with plenty of room to add an amp. The 10 and 12 inch kicker down firing models do not fit unfortunately, but this still improves the stock sound by a lot ... show more

  • De lo mejor en un tamaño compacto
Disfruto de muchos géneros musicales así que no busco nada exagerado solo un lindo golpe de bajo sin distorsión y musicalmente agradable y esto cumple. Las notas bajas llegan muy profundo tiene lindo golpe y cuando subes el volumen no distorsiona. También tengo el de 12" de Kicker con radiador pasivo pero ya es demaciado para mí SUV y ese ya a 10 metros se siente el retumbe y ya es para otra cosa. En cambio este de 8 este es para disfrutarlo dentro del auto y es un gozada, muy satisfecho. Golpea mejor que un SUB de 12" Rockford que era el que tenía antes me sorprende que siendo de 8" golpee más. Supongo que es por el radiador y porque al mirar hacia abajo el rebote de las ondas le dan más golpe dentro de la cabina. Sea como sea me quedo con este de 8" de Kicker 👌 ... show more

  • Great sound for such a small box
Super happy with the sound. The amp does over heat so not sure if because of the speakers or it’s the amp but the sound for how small this box is, is amazing!

  • Unfortunate
Subwoofers arrived in a dusty barely holding on box. When the subs were installed, they put the amplifier in protection mode. When old subs were put in their place, they worked perfectly. Not sure if there were defective wires or what was going on. Box was sound though.
