Alpine's Optim technology, built into their Optim6 signal processor and Optim8 amp, lets you tune your system automatically — just use the mic on your phone with Alpine's tuning app, and within minutes your system is tuned perfectly for your vehicle.

Alpine puts its Optim technology into two different products at present. One is the Alpine PXE-C60-60, which is a 6-channel standalone DSP you'd connect between your head unit and external amplifiers. The other is the PXE-C80-88, which gives you the Optim tuning capability with and 8-channel amp built in.
