My RetroSound Radio Install

Could you add an amp to the 6x9's instead of them being powered by the head unit?

Yes, definitely. The radio does come with RCA outputs for both front and rear. So you can use the rear RCA outputs to connect to an Amp. There's also an output to turn on Amp as well.

It's not bad for what it is. It has great features.

The only negative that I see so far is how thin the wires are for the power, ground, and speakers. Also, I don't like you have to plug a set of wires into the unit, then another set into the previous set. Look at the 3rd and 4th pictures from the top to see what I'm talking about (in the middle of all the parts are the wires). That adds unnecessary length of wires that needs to then be tied up or held up under the dash.

I think they can improve that with thicker gauge wire coming straight out of the body of the radio without needing so many things to plug in. Also, why a glass fuse? I guess when working with older cars you may have glass fuses on hand, but seems antiquated.
