This is a 4 pack of 6mm car audio amplifier spacers to provide a space between the amplifier and mounting surface. Most amplifiers sit flush against the mounting surface preventing airflow for underneath the amp. These spacers allow for airflow underneath the amp and greatly improve car audio amplifier cooling and are a snap to install.  (We also sell a taller 14mm high version Ebay item # ID-256790458243)

These are especially effective on amps with vents or a rear fan since for some reason amp manufacturers leave little to no space when amp is mounted preventing any airflow underneath the amplifier making the fan useless. These even even help on amps with no back panel fan or vents because the space still allows airflow under the amp and draws away heat from the amp case and back panel.

Features:

• Simple design allows use on any car amplifier
• Provides clearance for better heat dissipation and airflow
• Made from Black Impact resistant plastic ( no screws are included but you can use any drywall or wood screws )
