Bass blockers are a must whenever replacing the factory speakers in your vehicle. These will protect your speakers and will help keep them from blowing. Bass blockers will remove unwanted low frequencies from getting to your speakers allowing them to play the frequencies they were meant to. After installing these your speakers will not only sound clearer and more crisp but they will also play louder. Easy installation will protect your speakers allowing them to play for years to come. The recommended speaker size is given for a standard car audio speaker which is 4 Ohms.
