why rule out the phoenix gold? there going to deliver the sound you need. and have the bass you want.
what 4x4 fun was trying to say was with just a headunit, you wont have a speaer that will deliver bass and have loud highs. the headunit will distort by then.
but that happens with lower end lower bass handling speakers like sony or dual ect.
i would run the setup i linked. those comps have very nice bass just off the headunit power.
and add the 6x9s behind the seat and you will be surprised how it sounds.
the components i linked have a tweeter seperate from the woofer with allows the woofer to produce more bass while the tweeter gives you the nice detailed highs.
in a standard cab, you dont need alot to sound good.
