Question about Kenwood KAC-9152D Car Audio Amplifier
I have my amp running off of a separate battery in my trunk (not sure if that matters) but yea....one of the two 30 watt fuses on my amp keeps blowing out when i turn the volume up, i have two 12'' cvrs in a sealed box, ran into one channel @ 2ohms which is good with my amp,(it was also blowing fuses with them hooked up in separate channels @ 4ohms) im pretty sure the wires arent pinched.....im not sure why its blowing...that amp has always been able to put out waay more power...i have the gain turned like halfway so i know its not set too high....any good advice appreciated
Your amp is blowing fuses to protect your circuit. The type of 12V battery does not matter. For whatever reason you are over driving the amp. 2 Ohms sounds like a very low impedance for a car amplifier output. I am assuming you have the two 12" speakers wired in parallel. Most are rated at 4 Ohms which means you are pulling twice the current with the 2 Ohm load. Also, the bigger the speaker, the bigger the magnet, the bigger the coil, the larger the inductance, the heavier the load. Make sure these speakers are matched with your amp. A small amp driving large speakers will shut down at high volumes. Try putting them in different channels. Good Luck.
