None
I would go for a component set.
But if you choose between those 2 also think at the holes and fitting.
I would go for Infinity I think.
Usually I spend more than I can afford on sound in the cars
I would NEVER chop the rear covers to fit some 6x9 speakers.
They look BAD.
Why do people try to fit 6x9 speakers in the coop ? Do you think 6x9's sound better or what is the ideea ?
Get dome decent 6.5" speakers with filter and fit them in the back.
I am running medium and tewters in the front and I am running 2x 6.5" in the back also but something that would give a bit more beat.
I have isolated the holes with same material used in subwoofer housings and the sound is perfect.
For who wants more bass , get a bass box in the boot or get a flat active subwoofer.
