Upgrading my car's sound system (Honda Accord). I need some advice/suggestions.

I have an 07 Accord LX (Standard sound system, no navigation unit) and I’m looking to upgrade the car’s sound system. I bought 4 Polk MMC6500 6.5 speakers.

I’m thinking of getting an Alpine 9887 Head unit.

I do not know what replacement dashboard to get. Apparently, you need one of those to get a 3rd party head unit in the accord, unless you want to cannibalize the center-front storage compartment underneath, which leaves the stock unit intact but nonfunctional.

I would welcome some recommendations for Amp(s) and Subwoofer.

Thank you for reading.

Isn’t this the same question you asked just over a week ago?
