Yes that tells me you don't know car audio, I owned lots of 4ch amps and this opti 250x4 is the best so far.. The only downfall is the size. It's like almost 3ft long so if space is an issue,it's not the amp for you, but if u want a powerful clean amp this is the amp you want.
Gotcha, I will alter my opinion to match yours from now on. Thanks for the insight.
