With broad frequency response, these amplifiers are compatible with everything from subwoofers and midbass drivers to full-range speakers and super tweeters, making them a highly adaptable solution for everyday car audio systems.
Its compact heatsink design delivers high-fidelity sound with tight midbass and crisp, detailed highs. Ideal for users seeking powerful audio performance without breaking the bank, this amplifier combines sound quality with value.
The proprietary heat dissipation system keeps temperatures low, even during intense listening sessions.
Before InstallingYou must follow the instructions for the product’s installation to guarantee optimal performance. If you have any questions, get in touch with us. Before using the amplifier, always follow these guidelines:
Make sure the amplifier is switched off before adding or removing any connections. This prevents possible damage to equipment. Keep all cables as far away as possible from the ignition cables, electronic injection modules and starter switch since they may cause noise interference; Always use 100% Copper wire and good quality connectors. This guarantees reliability and performance. To avoid damaging the cables, make sure that they do not touch sharp metal edges. Important: For this amp use a 25A fuse 12 inches away from the battery as a safety precaution.
The power rating data is based on equipment from the PRV Audio Group laboratory. Rated power tested with 100Hz to 1KHz sinusoidal signal and THD
