Tropo 8" Subwoofers

Amazing sound quality, hits the lower frequencys that I was after, installed in a 2010 f250 super duty behind the back seats, in custom boxes I built to fit exactly the profile I needed, paired with a audio control 800 watt amp, these subs have a perfect sound reproduction for the 28-125 htz, peaks around 35 htz, would highly recommend using CT Sounds equipment, amazing quality for a great price.

I have 4 of these in 2012 f-150 and man they get down. wasnt expecting a whole lot from 8s. but was pleasantly surprized by how low they play.

Better than expected

Bought two Tropo 8 D4's last summer a just installed two more. Each pair is wired at 1 ohm powered by two Skar RP800.1's and they pound. Currently working on a custom spare tire enclosure, because my little trunk is a lot tighter than I expected
