Product Manuals

Stealth Bomber series amplifiers have been the cornerstone of the Cerwin-Vega Mobile brand
Embodying power, precision, and reliability for car audio enthusiasts.
Don't be fooled by the sleek and compact design of Stealth Bomber series amplifiers
They ensure seamless installation while delivering monstrous power output.
Lots of ground loop noise with this little guy. Was so disappointed that I had to return it.
Not sure how or why but even though I had multiple fuses to protect the amp it blew a fuse then blew the speakers. I would buy again though but im insane i guess.
It’s great for 6 1/2in speakers nice clean sounds good clean Resonance through full spectrum of sound through a set of nice speakers. not low end sounds. It will not push a sub for your life. all the interior speakers will out do the sub for low end. If you want bass get a different amp
The is the worse amp I ever brought. DO NOT buy. It keeps cutting on & off. Due to Covid I just recently had it professional installed and it’s crap.
Great product!
