alright.... first, ur speakers dont have to handle 22rms, 50max. u just have to get ur crossovers set correctly.
interior speakers arent suppose to produce much bass. Just like a 5.1 surround sound for ur home. u let the sub produce the low notes.
and thats Pioneers ratings (22rms, 50w max per channel) but actually only produce about 18 cea complient watts.
if u get a set of 20w rms 4x6'* and set ur bass levels and crossover points correctly u wont have anymore issues.
they also make 4x6 plate speakers (which have a seperate woofer and tweeter mounted in a plate (usually with built in crossovers) also invest in a set of bass blockers if u dont have a sub, so u can let ur rear 6x9 speakers take care of a LITTLE bass action.
