I am having a JBL GTO 601.1 amp and Pioneer SPL 2000 DVC Sub. Can the amp be bridged. How should I Connect the terminals, series or parallel.


I believe series.....hook a wire to the positive of one voice coil to the negative of the other.....with the remaining two wire that to the amp.....check on google to see if your amp is able to be bridged.....Most of the time on the bottom of the amp there will be a diagram or the the two outer speaker outs on the amp itself....let me knoe if this helps you...thanks

I have 4 wires what do they do I no to of thim will go to my Kicier ame I Ddont no were the other to go


OK, I am assuming that you have 4 wires coming from the subwoofer itself. Your subwoofer has dual voice coils, this means there are two positives and two negatives. Look closely at the posts on the subwoofer and you can tell. These wires will go to your amp, all four of them. Here's the tricky part. You need to know if your amp is a monoblock (single channel) or two channel amp. Also, what ohms is it stable at (4, 2, or 1). If you have a monoblock stable at one ohm, take both positives from the sub and put to the positive of speaker output on the amp. Then put both negatives from the sub to the negative speaker output of the amp. If your sub is dual 4 ohm voice coils, this will give you a 2 ohm load. If you have a dual 2 ohm voice coil sub, this will give you a 1 ohm load. If you amp is 2 channel, just hook one set of positive and negative to one channel and the other set to the other channel. Hope this helps

I have a alpine type r 15 inch it has two hook ups i cant figure it out i have positive two pos and neg two neg and it keeps cuting out one bridge two amp plz help plz plz


Ok, for starters. Is your sub a dual 4 ohm sub? If so, great. Is your amp 2ohm stable? If so, then great. If you are running one sub, is your amp a monoblock (single channel) amp? Are you running a two channel amp Your subwoofer is a dual voice coil subwoofer. This means that you have to have power to both voicecoils or risk damaging the voice coils. Subs are designed with dual voice coils to give it more control over the cone movement. This results in better reproduction of sound. Anyway, back to wiring.

This is for a monoblock amp (you can also bridge a 2 channel amp) Go from the positive speaker out of your amp to the positive posts of both voice coils. Then go from the negative speaker out of the amp to both negative posts on the sub. And there you have it. It's called a parallel set up. Setting it up this way just dropped the ohms load for that sub to 2 ohms. Less resistance means more power to the sub. Hope this helps

My Kenwood KAC-9105D amp quit working in the middle of a song. The music was loud, but I have had it louder before and it was fine. All the fuses on the amp and in the power cable are fine. The...


protection mode engages when there is either a crossed/shorted speaker wire, an incompatible speaker or a blown speaker with fried voice coils.

check your wires for shorts and/or loose strands of wire, your speaker ohmage (should be single coil, 4 ohm) and your speaker's operation. if you push the speaker in about an inch or 2 and there is some resistance, like its sort of scratchy when it moves, then the speakers voice coils are fried. speakers should push in and out freely, with no scratchiness or resistance, until they bottom out at 1 to 2 1/2 inches.

if it is not the speaker or the wiring, then the amp is damaged.

HAVE KIKCER L7 WHEN HOOKED UP TO AMP IT DOESNT DO ANYTHING HOW COME


lets do some diagnosis.. if it's possible, try hooking another known good sub up to the amp and see if that works. if it doesnt, it's an issue with your amp. if it does work though, it's an issue with your sub. or the wiring. if it's a dual voice coil sub, make sure you've got both positives hooked up to positive from the amp, and both negatives hooked up to negative from the amp. if you've accidently got positive from the amp going to positive of one voice coil then to the negative of the other, and the negative from the amp going to the negative of one voice coil then to the positive of the other, the voice coils will be pushing against eachother cancelling eachother's movements out. and this will fry the sub. OR the sub is already fried.

I am running two 15 spl soundstream woofers with a soundstream 500sx amp how do I bridge them to get maximum performance


the 15 spl woofers are dual voice coil, i believe 2 ohms per voice coil.

the 500sx amp is rated 4 ohms bridged at 500 watts, it is capible of dropping to 2 ohms sterao, but no lower than 4 ohms bridged. to get maximum performance, you cannot use both voice coils of both speakers, you can only use one speaker, or both speakers, while only using one voice coil from each.

there is no point of bridging them, you can achieve maximum performance by attaching one voice coil from each speaker to each channel of the amp, while leaving one voice coil from each speaker unconnected. you could also use just one speaker, attaching one vioce coil to one channel, and the other vioce coil to the other channel. then, i would suggest getting a second, identical amp to run the second speaker.

if you are persistent on bridging to mono, then you can only use 2 voice coils (both from one speaker, or one from each speaker) and you must run the voice coils in series, that is, from the amp positive to the 1st vioce coil positive, then run a jumper wire form the 1st vioce coil negative to the 2nd vioce coil positive, then, finally, run the 2nd vioce coil negative back to the negative of the amp.

this is all assumming that each voice coil is 2 ohms and each vioce coil has seperate inputs, meaning that each speaker has 2 pairs of speaker terminals.

550x2 subs....SPL z2x-820 Amp


Hello,

The 230 watt amp is a little small for your subs. They'll work, but if you are looking for max SPL, you won't get it. To push those Audiobahn's to their potential pavement shaking max, I would recommend an amp in the range of 500-600 rms (2-channel bridged) or 1000 watts rms monoblock.

Hope this helps.

Best Buy is your problem! Just kidding....kind of. One thing that I would check is to see if there is by some strange reason, an air leak in your box. If there is a decent leak that will substantially bring down the sound output. Otherwise, but you could potentially be getting bad hearing or just getting use to the loudness. I have had the same thing happen to me. I work professionally at an audio shop and am an SPL competitor. There was nothing wrong with my system it just that my ears have gotten use to the beating. Let me know what you think.
