Noob needs advice for his Alpine CDA 9833

If you replace the stock speakers you will want an amplifier to drive them, the deck power will not be enough. They will get both louder and much cleaner with dedicated power from an amp, a good 4 channel that matches whatever componants you get for the fronts would work great, and if you want you can get one strong enough to handle the rear doors too if you go that route. Will need to know what size speakers are the factory stuff and what is your budget to accurately answer the rest. You can probably get away with a small sealed box with an effecient 10" sub that can be tucked away in some extra space, a sub does make a huge difference even for hard rock, which is primarily what I listen to as well. That would require another small monoblock amplifer though or you could go with a 5 channel for everything.2003 Chevrolet Silverado Standard Cab ~ Alpine CDA-9851
