    Icon32 Help with Overheating Amplifier

    My amplifier overheats when I have it bridged to my Rampage subs. The subs are 2 12" in a sealed box. The amplifier itself is a 4 channel and has two 25 amp fuses, so about 500 watt RMS right? I think the max on the amplifier is 1600 watts it said? The subs are 1200 max. When the subs are hooked up to two separate channels the amp is fine and stays cool, but when I bridge it, the amp excessively overheats to where it burns to touch. I took it to Autozone and an employee looked at it and said that my power wire was not a big enough gauge for my amp and that I should at least have 4 gauge. Right now I have 6 or 8 gauge. Wouldn't having too small of a guaged power wire result in just a poor performance from the amplifier or overheating in the wire and not the amplifier? The wire is not overheating, just the amplifier when it is bridged. While bridged, the quality from the Sub is great, but it just overheats and I'm not sure what the problem is.

    First off Autozone shouldn't even be considered as a place to go to for audio stuff. Second what ohms are your subs and are the single voice coil or dual voice coil, and what are the full specs of the amp?



    Headunit - Pioneer DEH-P8300UB
    Subs - None
    Sub Amp - 2x Crescendo 3kwp
    Front Stage - Polk Audio db651 Coaxial
    Front Amp - None

    They're Renegade subs not rampage haha. I went to Autozone for a free alternator test and the guy told me he used to work on audio systems and asked about mine and that's how that was involved.

    Re: Help with Overheating Amplifier

    I couldn't get a single sub spec so going by the info here, 2 of these subs will equal a 2 ohm load. I think that's your problem.

    Also, after turning the volume up higher on the headunit the amp goes into protect. It only does that when the car is started. If the car is simply on then it won't go into protect, but still gets hot.

    Re: Help with Overheating Amplifier

    Like already said the subs are prolly 4 ohms each. So connected together and then bridged you have a 2 ohm bridged load. Not good you may blow the amp. Yes the 4 gauge wire is needed but so is a proper ohm lad on the amp. Try this connect both subs to one channel of the amp. Not bridged and see if the amp gets hot. Be it won't So either new subs or amp is your option here and the wires
