Just because the box is built for those subs doesn't mean it works well in your car. it's all about airspace if its in a sedan trunk try facing it towards the back of the car it will give it something to bounce off. If the box has one tiny pin hole it can make a BIG difference make sure it is sealed well. Make sure your positives and negatives are going to the right places on the speaker wire that can cause weak sounding subs. did you bridge the amp because that could be an issue also.

I have a kenwood kac-9152d amplifer and it works just fine for about 10 minutes then just shuts off and subs dont work, about 30 seconds later my amp turns back on with the subs.


make sure it's well ventilated. If there's no air flow, then there is no way of cooling down and to protect itself it will shut off. Make sure the speakers are wired correctly as per amp specs. too many subs or subs connected improperly can draw too much current and shut the amp off, but you will notice this when you turn up the volume to a certain point and the amp shuts down.

I have the Alpine MRP-M1000 amp. I want to use 2 subs with this amp. Which Alpine subs would work best with this amp?


this amp is rated at 600w at 4 ohms and 1000w at 2 ohm so as long as you calculate your speakers to match the ohm specs of the amp you can hook up

parallel = pos to pos and neg to neg of the 2 speakres
2 - 8 ohm speakers in parallel = 4 omhs
2 - 4 ohm speakers in parallel = 2 ohms

series = pos to neg of the 2 speakers
2 - 1 ohm speakers in series = 2 ohms
2 - 2 ohm speakers in series = 4 ohms

Amp makes noise. I am purchaseing a new amp


Hello termite440,

A mono amp will generally provide more power for subs. And for those Audiobahn's, you'll want something that will provide a minimum of 500-600 watts RMS to each, a least a 1000 watt amp. At the low end, something like the Alpine MRP-M1000 or the Orion HCCA-D2400 will provide 1000-1200 watts. I'd recommend the Alpine. For more power, and another $100, look at the Alpine M2000, or for another $250, the Rockford-Fosgate T1500-1bd.

Hope this helps.

Have kenwood mono amp 4,2,1 ohm capabilitie. What is the best sub to run. The amp is 1600 watts, howmany ohms and 1 or 2 voice coils.


Hello pelikant75,

The best answer depends on your budget for the sub(s) and exactly what kind of sound you are looking to get. Your amps RMS output at 4 ohms is 200 watts and at 2 ohms, it's 400 watts. I could not find that it was 1 ohm stable.

If you are looking for the absolute best bang for your buck, I would highly recommend a pair of entry level MTX 10" subs, model 4501-04, currently priced by Crutchfield at $49.99. And if you buy a pair, they throw in a free Bass Slammer BS210S sealed enclosure. The MTX's power range is 112.5 to 225 watts each, right in there with your amps output. 2 of them in parallel give you a 2 ohm load, just right for your amps best power. And they sound great. You simply can't find a better deal for $100 bucks!

If you want a little better SQ, a pair of Rockford-Fosgate P1S410's should be considered. Again, going to Crutchfield, they currently have this one "BOGO" (buy one get one) for $99.99. You will have to provide your own box, though, no free one with these.

Finally, if you want the best SQ, and your budget allows, consider a set of Alpine SWR-1022D's for $179.99 each. These have dual 2 ohm voice coils, allowing you to series the coils and parallel the subs, resulting in a 2 ohm load to you amp just like the MTX's and RF's recommended above. You will probably want a somewhat larger enclosure for the Alpines as well as a fatter wallet. Your amp is right at the lower end for powering them, so they probably will not be as loud. But they will sound good.

One thing we haven't discussed is the box. The enclosure is just as important, perhaps even more important than the sub(s). More accurate bass is generally produced from a sealed enclosure. A ported enclosure will be louder, but at the expense of sound quality. And whether it's sealed or ported, the enclosure needs to have enough internal volume for the particular sub you are planning to use. A sealed box in the range of .75 to 1 cu/ft will be OK for any of the recommended subs. Add about 15-20% more volume for a ported box and keep in mind that the port needs to be specifically sized for the frequency for which it is tuned.

Hope this helps.

3 amps 2 subs sound system for car, need wiring help


As i read your problem i can recommend you that connecting each of the hifonics amp to each hifonics sub with the same specs by getting the specs in interfacing the two or you can simply look to the output of the amp and the input of the sub and find a suitable plug that fits to them.

In the case if you want to run each hamp to individually run each sub but sharing 3 farad capacitor: what i can suggest is that you connect in parallel one connecting wire of each input or ouput of the amp or sub. Its like connecting a connector from each of the input or output of the amp or sub to one leg of the capacitor, and connecting two wires to the other leg, one is being connected to the amp or sub and the other wire is connected to the other amp or sub.

In the case of putting a circuit breaker at the car battery: what i can suggest is that you find an appropriate circuit breaker that fits the specs of the car battery then connect it in series on the positive supply or read the specs of the circuit breaker before you connect it to the battery. Having a circuit breaker is like having a fuse but with special advantages in favor of the circuit breaker.

In the case of having power to the amps you can run one power wire to the amps by dividing the power wire into two, one connected to the amp and the other wire to the other amp. Then you can connect each amp and sub in series individually by connecting one wire b/w amp and sub. I hope i solved your problem
