May I be permitted to change my mind?
I drove at 80 mph or so on I-90. The CDA-7876 produced enough clean watts to listen comfortably.

Next time you get the chance, I suggest checking out someone else's system at highway speed, top down. What one person considers distortion, or "unlistenable", is relavite. Maybe at your next local meet, bring a CD of your typical driving music with you, and have someone with a setup similar to something you might consider purchasing take you on the freeway for a few minutes. It could save you a lot of money in the long run.

External all the way!

I tested the 60x4 and it sucks at high volume. I crank it with the external amp now and I can go as loud as I want without any distortion. Spend the extra money now rather than replacing components later.

 

A couple of things to consider with amplified head units. I cannot say whether it is better to use it or not as it will depend on the application. But if you know all the facts, then you can probably make a more informed decision. I do not think there is a right or wrong answer but whether it meets your specific requirements.

1 - beware of manufacturers specs. If it says 60W x 4 be sure that is also says ALL CHANNELS DRIVEN. If it does not say this, what it means is that you get 60W per channel (regardless if this is RMS or not) but NOT at the same time. This usually leads to clipping at higher volume.

2 - Power - compare the power cable from a true 60W x 4 amplifier and the wire on the h/u...this will be another limiting factor

3 - Distortion level - probably much higher on the amplified h/u than a dedicated amplifier

4 - Size - how can a good amplifier fit into the small space along with all the other electronics required in the h/u? The power transistors are usually smaller, therefore cannot conduct the same amount of current.

5 - Heat - amplifiers in the h/u add more heat in an already cramped space

Again, this should not discourage the use of a amped h/u, just give you things to consider...

just my 2 cents.
