Car subwoofer problems

Ok.(2) 4ohm 800w max pioneer sub. (2) poineer 760w amps, running bridged at 380.
i have a battery in the trunk hardwired to my underhood battery. i have a 100a inline fuse from the pos on the battery in the trunk, next is a unfused distribution block which turns one 8g power cable to 2 8g cables. it then runs to a 5- farad cap. the cap is grounded to the chassis. the amps are hooked up to the cap, 2 pos and 2 neg. the remote is hooked up between amps.

the problem.

the right sub is burning out. it just pops and stops working. it sends the amp into protection mode, it will lose power and turn back on. i replaced the sub and it worked great for about 20 minutes and then it crapped out again. the amp on the right which is wired the same except for the larger ground cable (4g) is still working fine with no issues. the right amp only has a 8g power cable.. could this be the issue? i dont know please help..

    in the end of the post i mean 8g ground cable, as in the right amp has an 4g ground, the right only has a 8g ground, and thats the amp which seems to be blowin the subs

    i think it is a wiring problem, but not size issue. the only thing is the sub that is workin fine that amp has a 4g ground cable and the one which doesnt work right has a 8g ground.. the right amp works fine and is continuing to work fine..

    the amps are pioneer and the subs are pioneer.. yes

    Are your speakers the exact same brand, and are your amps the same?

The cable should not cause the problem unless it is shorting out somewhere on the remote or positive cable. I would use a larger gauge wire first as this is the cheaper way to go, and if the same problem occurs you are having a short in the sub or box causing the protection mode. You will have to back trace to find possible cross connections.

I have 2 pioneer 6x9 400w, pioneer GM 6500f 760w amp and a kenwood KFC W1012 sub, how d i get the best sound from these?


pioneer gm 6500 is a 4 ch amp rated at 60w-4 way to small of an amp to run your sub. UNDER-POWERING your sub is more likely to damage spkr than over-powering. my advice,get mono-block to run sub

What kind amp should be use for ts-w307d2 subwoofer speaker?


Nice sub, i have 2 308d4s in my car. Okay this sub is a dual coil 2 ohm. so to get best bang for your buck you'll want a 2 channel amp and bridge it. Your sub is 400 watts RMS, So you'll want an amp that has the same rating. I'd recommend the pioneer GM-5400t. Then wire your voice coils in parallel, and bridge your amp, you'll get 380 watts RMS, which is perfect for this sub. If you have questions on wiring or anything you can just ask. thanks, i hope this helps

Subwoofers don't work all the time.


I've had similar problems in the past with speakers. The most likely culprits are 1) over excursion of the subwoofer. If you have the bass boost or gains set too high, the speaker recieves a distorted signal,the amplifier would likley read this as an open vioce coil and engage protection circuitry. 2) a voice coil on the verge of collapse(same result as above) 3) your amplifier is running at too low an impedence(some can only bridge into a 4 ohm load) and is over heating. You may be pushing the amp beyond its ability, and it is over heating. or. 5) the amplifier has faulty internal circuitry(least likely but I had a brand new amp with a dozen cold solder joints on the printed circuit board) and is cutting out as a result of inadequate electrical transfer.

I have the pioneer sub and a sony 600watt 4


it has a detector that kicks in it will usually shut off your amp and it keeps you from blowing your amp the speaker may have to much power and amp may not push it it will start to protect itself

Wiring


Usually an 800 watt peak sub would be a 400 watt rms. Hmmmm. Anyway, just bridge the amp (1x 380) nd keep the gain up enough to stay clean. Watch the sub and turn up gain until it starts to distort, then back it down a hair. Do this with the CD players volume up 2/3 to 3/4 volume with the BASS and treble at zero (bass better at minus 4 or so if you are a bass head! Hope thishelps.

How to


First of all, make sure your amp is bridgeable. There are a few ways to bridge subs. series: hook one wire from the negative on the left amp output (or whichever is labeled on amp for bridged)to left sub negative. left sub positive to right sub negative, then right sub positive to the amp positive output.(like a big loop through both speakers) parallel: both speakers get their own set of wires, both negatives go to the bridge negative terminal, and both positives go to the positive bridge terminal. Series-parallel: A combination of the two. say two speakers in series, and one hooked up alone, but all to the same amp outputs. Bridging your amp/speakers basically lowers the resistance of the circuit and makes more current flow, more power, louder, harder hit. In series, it also makes both speakers do exactly the same thing, instead of "stereo sound" or L/R differences. What you're probably looking to do is Bridge in parallel. That will drop the resistance of the circuit the lowest, allow the amp to put out the most amount of current to the speakers, and allow your bass to hit the hardest. If your amp only has one output, hook up the same way as above. Just see what resistance your amp is stable down to. If down to 1 ohm, no worries. if stable only to 2 or 4 ohms, you may want to bridge in series to be safe. That will cause the resistance to go up, and will not pull as much current through the amp. The whole time, just remember Bridgeing and higher current mean HEAT so watch your amp. I hope this helped.

USING 1 CHANNEL


I can't find any documentation for your amp; it was made when Jensen was owned by Recoton, and they're no longer in business. With any 4-channel amp, you can't bridge all four channels into a single channel. What you can do, if you're connecting it to a single sub, is to bridge two of the channels into one channel and leave the other two channels unused. It doesn't usually matter which two channels you pick, but some 4-channel amps designate channels 3 and 4 (or rear channels) for the subwoofer. Whichever ones you use should have a "LPF" or "LP" crossover setting available.

Amp is on, Subwoofer works, but no sound.


here is a short test you can try, remove the rca audio cable from the amp & connect a diskman or toher audio o/p device that you can hook up with the same rca wires, turn on the amp & see if you have sound. you can also remove the speaker wires from the sub & using multi meter read the ohm's of the sub, most subs are 4 ohm. Hope this help locate your problem
