Ok i have a Solo Baric S10L7, and it has dual voice coils, but im not sure if its a dual 4 ohm or a dual 2 ohm voice coil. My problem is i have a Kicker KX300.2 Amp with this sub, and it is bridged. I mean it hits somewhat good, but the amp heats up too quickly, and shuts off if i turn it up a little more. would the way its wired have anything to do with it? I mean im using 4 gauge wire, 120 amp fuse, i have a cap, and everything, but im not sure why it shuts off all the time. does the ohms have anything to do with it, or is it the amp? would it be possible to get another Kicker KX300.2 Amp, and use one amp per voice coil? please help me out thanks.

the way its wired has EVERYTHING to do with how much pwr the amp puts out, and that will also effect how hot it gets. We will need to know the exact model of your speakers, or the impedence/voice coil configeration to help you.

Thanks im going to go check on the exact model of the sub, and see how many ohms each voice coil is. but im pretty sure its dual 4 ohm, and the 2 positives and the 2 negatives, are wired together from the voice coils. Now from the box i just have one positive and one negative, so I think thats the problem, because its dropping the amp down to 2 ohms and its pushing 600 watts RMS when it shouldn't be stable at that rate. Im thinking of just getting 2 300 watt amps and have each voice coil to each amp at 300 watts RMS each.

Indeed, the ohmic load has a lot to do with how the amp will react to a given sub load.
It sounds like your sub coils are wired in parallel to each other, then to the termination on sub box and out to the amp outputs.
If you have the 2+2 DCV, your net load is 1 ohm to the amp.
If you have the 4+4 DCV, your net load is 2 ohms to the amp.
For now, you may want to consider wiring the coils in series to the bridged amp. Even if the amp is seeing an 8 ohm load, it will be safe for the amp and still getting about 150 watts RMS to the sub. However, if the sub is a 2+2 DVC, you are at 4 ohms net load and a good match for the amp when bridged. (+300 watts RMS)

Hey thanks, this is the first time something has really made sense, and has really helped. ok so now after looking at page 5, i understand the Parallel wiring, and thats how i had it. So i was running my amp at 2 ohms. But i wired it differently today, i have voice coil # 1's (+) and (-) to one channel, and Voice Coil # 2's (+) (-) to the second channel. So is that wired correctly as series wiring where the amp is recieving an 8 ohm signal or what? Kicker says THAT SUB the KX300.2 can handle 150 Watts RMS per channel at 2 ohms, and be stable, just not bridged at 2 ohms, so how do i get 150 watts per channel RMS? please any help is appreciated thanks.
