For 135$ a sub and cheaper when they give 10% on the website gpcaraudio.com. get a soundqubed 10 inch hds3.110 series. 1200 watts rms. U won't be disappointed. These slam. I have 3 in a ported box tuned to 35hertz. Also swapped them out with the reaudio sxx 1200watts rms I have and the difference was night and day. These easily out performed the re's and they are 200$ each subs. What a rip.
