Just got a new 2011 Honda accord coupe and was looking to get a new head unit and speakers. Any suggestions would be greatly appreciated

And a vintage Kraco head unit, cassette if you can find one.

 

Jesus.
I am in a 2011 Accord right now.
Front components, tweeters are in the sail panels, which isn't great but aiming is ok.
Get matching rear components but you won't connect the rear tweeters. No rear tweeters.

You want a head unit with built-in time alignment. Ideally an external amp, but if you go with Alpine you can get the KTP-445 which is plug and play for extra power.

Crutchfield will tell you what fits and give you the necessary adapters, speakers won't bolt in directly, an adapter is required.

Start at Crutchfield, come up with options for a head unit and speakers based on your budget and preferences for HU options and features. Then we can comment on our opinions.
