Conclusion: I have a 12" sub and 2 6.5" speakers. I chose to use the 6.5's in my 95 isuzu rodeo as little subs instead of the 12" to save on space. The speakers are rated at 50 watts rms so this amp is perfect for them.
Conclusion: Always been faithful to Pioneer auto audio, due to the great sound results I had though many years and systems I installed in my vehicles. This amp is one of two I just installed in my GMC Sierra pickup truck to replace the crappy factory Bose system.
