It sounds like your speakers are out of phase. Check very carefully the polarity is the same on both speakers (at both ends). That'll certainly get you sounding better.

Can i use a 300 watt amp for 2, 800 watt woofers


yes, but you would not get the same performance as you would if you gave them the suggested power. I have found that it is always better to use a more powerful amp than your subs are rated for (as long as it is clean, high quality, low distortion power). I have had the best luck with name brand amps (kicker,rockford fosgate,phoenix gold,etc...). I hope this will be helpful to you.

What r the parametric specs for the ma audio hk15x2


Fo (Hz) : 29.581 QMS : 3.965 QES : .517 QTS : .457
VAS (liters) : 147.723 REVC (Parallel-Ohms) 1 SPL @ 1 watt/ 1 meter (dB) : 90.6 X-Max Linear peak-peak (mm) 70 LEVC @ 1kHz (mH) : 1.043 Enclosure Volume (Sealed) : minimum 2 cubic feet Fill Required % : 0 3dB down point (-3dB) : 43 maximum sealed: 2.5 cubic feet n fill required: 39 at 3 dB down point Enclosure Volume Ported Vented (cubic feet) : 5.0 Vented to Hz: 35 3dB down point (-3dB Hz) : 28 Square port area Sq/In : 80 Port Length : 13" Power Handling : 2000 Watt RMS & 4000 Watt Max. Make sure to use MDF for the enclosure and use 1 inch thickness and use braces as well. This is a beast of a sub woofer. So give it the proper power it needs and make sure that your box is very solid in construction. If installed correctly and given the right power, this sub woofer is bound to put a smile on your face and rattle your bones. I hit 142dB with only one of these subs and im sure if i gave it more power i could hit the 150dB range. DON'T FORGET TO GIVE IT THE POWER IT DESERVES. Have fun dreamsystems.

Coustic Car Audio 12RS Car Speaker Watts


That all depends.

I have a Sony Xplod Sub, also 12" and 4ohm, and it is a 1000w sub.

But my friend has sub that is also 4ohm and yet it is only 500w.

The ohm mean nothing when trying to figure out the wattage.

Try www.coustic.com for more info (site will not load for me)

If i put the TS-swx310 sub in a bigger box would it get help the sound.......i have a 12'' regular sized box and the speaker is going in a car now???


It is amazing the difference box construction can have on the overall sound of a system. Size is only one factor. Using a larger sealed box may make the sub hit lower, but not necessarily louder. Because the TS-swx310 is a shallow mount woofer, it is designed to run in small enclosure. Putting it in a much larger box could potentially cause damage to the woofer over time. If you want more bass my advice is to use a normal woofer in a box built to spec for it. Generally a ported box will provide more output, and sealed hits tighter. It all depends on the type of music you listen to.
Hope this helps

Car subwoofer just past half volume cuts off the amp


Assuming there is no short, or lose ground wire somewhere inside the box, diodes( in the amp) are fine, you might be overheating it by not allowing it to get good ventilation. This can be a big deal on some low end Chinese amps. Or the speakers are blown , or your Resistors (in the amp) are bad, but for arguments sake.
Most people don't use the proper size and or conductivity types of wiring, for pushing high amperage Think about it like this, Watts (power) =.Amps (energy) x Voltage (pressure) Resistance or Ohm's (amount) determines how much Wattage will go in or out, Ohms = Volts x2 / Watts.
What gauge wire are you using on your setup?

Sony X-Plode amplifier. NOT working


It is possible if the model amp you have is bridgable to 1 channel. Usually when you bridge an amp you will need to hook one wire to the positive side of one channel and the negative side to the other. You will need to consult you user manual for the amp or get the manual from the sony website for instructions on how to bridge the amp or if the amp is even bridgable.

AMP FOR MY SONY SUBBS


Get an amplifier that is rated just under the power ratings of the subs, that way you will not blow the subs by pumping in too much power to them. An example is, if you have 2 subs that are 500 watts each and you are going to connect them in stereo mode, you need an amp that is no more than about 400 to 450 watts per channel. This will push them very hard, but will not blow them by overdriving them. If you are going to connect 2 subs at 500 watts each in a bridged mode (in parallel across both channels) then you need an amplifier that is about 800 to 900 watts total power for both channels. This is basically the same power ratings for an amp, but some amps are mono (just one channel) and will have just a total power rating, while other amps are 2 or 4 channel amplifiers and have a rating for each channel.

I hope this helps in your decision making, if you need more help let me know. I have been repairing car audio equipment for almost 20 years and have seen just about everything.

alot of times its not just the amp that gives you better sounding bass.. A lot has a to do with a few other factors as well.. first off your subwoofer.. the bigger the subwoofer the deeper the bass. Some woofers exturde, or flex differently depending on the quality and structure of the woofer.. 2nd is gonna be the sub box. different size boxes will give your sub diff. depths of bass. ... general idea is the bigger the box deeper the bass. But if your woofer is not supplied enough power a big box is useless.   With that size amp your best bet is too run a single woofer. Probably a 10inch woofer would sound the best.. but it in.75cub inch. sealed box.. should sound great.
