Suggestions on aftermarket stereo system?

[CoralReefer]

I posted this under the Electrical Section and there's not much activity there. I figured I'd repost here:

Looking to upgrade. I was thinking something built custom but didn't know if there's any good packages out there for sale? I've searched all over and keep finding the same things. I'm looking for a four speaker setup with a sub and amp.

I recently installed a double din DVD\TV\Stereo system, has remote control and you can attach two additional screens and an amp, can also attach a camera on the bow or in engine compartment

Works fantastic

You may...depending on budget have to;

Upgrade the amp..(if it has one)

Speakers are next...(don't save money here)

Sub will make everything sound better..

1,500 for the whole deal...give or take a couple hundred.
