I am wanting a pair of 8" speakers to mount in my center console. I am using them as dedicated subs/ mid bass for when my subs are off. They will be in a sealed maybe ported box if I have room. Not looking to spend a whole lot on a pair. May even go down to a 6.5" if they a good. Just looking for some strong bass when my girl is in the tahoe with me, she says the 21's are too loud to enjoy. Oh power, um my 6.4 can do tri mode and I have two channels that will do 300 @ 4 ohms. So I can do 4 low powered 8 ohm speakers or two 4 ohm.
