I'm planning on installing a after market head unit in my '99 Maxima w/ Bose.

There are two adapters that I have the choice of using:

!) The Scosche OEA-4 adapter. This adapter has output levels for each speaker that can be adjusted. http://www.crutchfield.com/App/Produ...C4NN03&tp=3486

2) The Metra 70-7551 adapter. This adapter comes with RCA cables that integrates the stereo through the head units outputs. My head unit will have 4 Volt outputs which have decent clarity. http://www.installer.com/item/displa...php?it=70-7551

My question is this:

Which adapter will deliver the best sound? The one that connects directly to the units output or the one that has level outputs for each speaker?

Thanks

 

Depends on what aftermarket HU you are going to buy. If the aftermarket HU has 4v outputs or greater, then I would go wih the 70-7551.

 

I'm leaning towards the Kenwood Excelon X-492. What do you think about this unit? It comes with 4V outputs.

 

Any other car audio Guru's out there that can shed some light?

 

With that HU the metra 70-7551 will be fine.
