Need 6x9"s for my amp

[Alpine2005]

i have a PG 75rms x 2 @4ohms amp i'm useing right now and i would like to use it.

are the pioneer ts-a6981r or ts-a6991r speakers good?

do they have SQ? and good bass response?

do they sound as good as the alpine type-s 6x9" speakers?

IMO Pioneer are good speakers to run of your HU as rear fill, but to amp them i would be a waist of time, Thus i recommend get the alpine you will be happier
