Strong and Punch and Built Solid
Model: 51PTRTP10
So far so good. In my 2025 honda civic hatch it wont rattle the neighbors windows but it will rattle that hatch at high volumes. Great value and seem to be built very well, time will tell if it lasts and Im optimistic it will. Provides a strong punchy low end but nothing extreme for those that are looking for a more balanced sound in there system. ... show more

Excellent choice for more bass
Model: 51PTRTP10
Perfect all in one unit for more bass. Since it includes the enclosure, amp, and sub with passive radiator all you need is a wiring kit.

Quality unit at this price range
Model: 51PTRTP10
Good sturdy unit and does what it says. Adds some nice deep sound to less desirable stock car audio. Added this to my 24 Silverado and made a significant difference in the quality. No need to change the stock speakers at this time.

Just what I needed!
Model: 51PTRTP10
Sounds great! Fits precisely where I needed it to under the cargo area in my SUV. Should’ve bought it years ago.
