right now i have a sony xplode cd deck (52x4) running the bose with there amp. it bumps (what i like)but the quality isn't that good. if i get different speakers (sony,kenwood,etc. without an amp) will they kind of bump.

 

Depends on what your depinition of "kindof bump" is. You mean bump like a exaust from a civic or bump like an exaust from a maxima...?
