SOURCE: adjusting wattage on kenwood kac 9103 class D mono amp

That amplifier is 900W x 1 @ 2ohms.
If your subs are 4ohm SVC wired Parallel, resulting in a 2 ohm load, each sub will only see 1/2 of the rated power. (450W ea.)
Your gain (sensitivity) setting should be between 75% and 85% to max. You will be fine.

SOURCE: High x-max vs. high sensitivity

Sensitivity is a representation of efficiency. The higher the efficiency, the better the sound quality.
Xmax is a measure of the "throw of the cone peak to peak. This is a direct representation of the volume of air the subwoofer will displace..
A High X.Max subwoofer will displace more air - and therefore produce more SPL in a vented enclosure.
Sensitivity on these subs aren't crucial, because the customer is looking for LOUD and will purchase a large class D Mono amplifier to power it - characteristically low in sensitivity as well due to the way the power is inverted. Highly efficient, yet low sensitiviy.
I am definately a basshead! My show car has (4) 15" Cerwin Vega Stroker PROs. (one of the most highly EFFICIENT high xmax subs available) (86dB). (36-44mm Xmax (adjustable for SQ or SPL)
ea141e4.jpg If you are looking for SPL, High XMax, Low sensitivity, and lots of power is the way to go. Generally, to increas SPL by 3dB, yuo must either increase surface area of driver 2x or double the input power. Slot ports, aeroports, and loaded horn ports can also increase your dB level by up to 3dB as well.
Properly constructed enclosures have an effect as well. Instead of wasting some of your power on vibrating the enclosure, it should be braced properly to reduce the wasted energy.
All of these tips will add tou your satisfaction of the product. You can make a $100 sub sound phenomenal in a proper enclosure, and a $400 sub sound like $hit in a prefab or poorly constructed one.

Your original question - with all things equal except the subwoofer, the subwoofer with the higher Xmax should yield the most SPL - due only to the fact of air displacement.

If you have additional questions or need clarification dont hesitate to ask.

SOURCE: kole amp in protect mode?

Are you setting the bridge switch for both left and right or are you trying to run both subs off of one set of terminals? If you running the subs off one set of terminals you are effectively running the amp below 2ohms and thus the amp is not 2ohm stable and you will destroy it.

Some amps actually all ready run a bridged output for left/right operation, this could also be the reason why the protection circuit is kicking on.

Either way it's a component mismatch and you either need a stronger amp or different subwoofer setup.

If my amp is rated at 1800 watts rms at 2 ohm. Would it make my memphis 12 hit hard


Depends on the exact model of your speaker and the amp. Most amps are overrated and the spec your referring to is probably the max when hitting. The speaker will probably blow unless your running 2 of them wired in parallel that will give you a two ohm load if the speaker is rated at 4 ohms. You can adjust the output of the amp to keep from blowing them. After everything is installed make sure you car is running and your head unit is panned to just the sub output. Turn the output on the amp to zero. Use the type of music you listen to the most and turn the head unit all the way up. Then turn the amp output up until the subs start to distort then back it down a little. In this way you shouldn't blow the speakers. Also the box design is important. I have found most speakers have a web site that will give you specks on a box design. ported, sealed and the like.

Which amplifier i should use with JBL CS-1205T


this sub woofer tube has a rms rating of 275 watts... try using a kicker or orion 600 watt mono amp to run this. the brand name is what tell you about how good an amp is for instance the names i just mentioned rate their amp by standard play frenquencies where as other lower brand names rate their amps by the max out put on certain subs at certain frequencies which may lower their impedance and create more power although you will never play your sub at those frequencies. as for the max power of your sub of 1100 watts that is more than like only at a certain frequency so always only double your rms rating of your sub to find max power handling.

Not sure if you are getting two subs or single?

Anyways, amp is rated at 800 watts and probably under rated so it will push sub. Remember that you don't need to worry about max power, rather focus on RMS power rating.

Wiring for 2 subs for max performance


This amp is rated at 500 watts into a 4 ohm load bridged mono or 250 watts x 2 into 2 ohm load stereo. Do not go below that impedance in either case. The amp was meant to dissipate a certain amount of power, driving it to hard will lead to damage. Your speakers look like they are dual voice coils @ 4 ohms each. To get the max power while still saving your subs would be to parallel the voice coils on each woofer then run them in stereo with your amp. Stereo 2 ohm is 250 watts per speaker.

Is amp big enough for speakers


Hello,

To run 2 subs, the amp would be a little small. The subs will run OK, they just won't be very loud.

It's usually better to compare and match up the RMS power rather than the peak power. The Sony XS-L10P5B sub has a peak power handling figure of 1200 watts, but the RMS is 300 watts. The Sony XM-ZZR3301 monoblock amp puts out 1100 watts peak, but only 330 watts RMS. They would work great together, 1 sub, 1 amp. But if you add another sub, each one would only be getting about 165 watts. They'd work OK, just not as loud as they could be.

Hope this helps!

Support Question about RMS


you are going to need an amp that can supply the right amount of rms power to make it sound good. these sony subs are rated for 380 watts rms. so in order to find an amp that will supply two, you must multiply that figure by two. so you will need an amp that can supply around 500 to 750 watts continuously (or rms). also you are going to want an amp that is either class d or class ab rated. these amps are built to push subwoofers exclusively and will give you the best efficiency and sound out of your subs. you will also want to get an amplifier is a monoblock amp, and not a stereo amplifier. make sure the amp can put out that rms rating at 2 ohms as two 4 ohm speakers equal 2 ohms wired in parallel. i have a kenwood kac9152d that puts out about 2000 watts max at 2 or 1 ohms (900 watts rms) that i used with my two sony xplod 10's for about 2 years. it was kick ***! now i dont know if you need that much power but they will handle it as long as you dont push them too hard for long periods of time, otherwise you might end up blowing them up! (depending on the box size that is, and the quality of it as well...)

i have years of car audio installation experience and can help with setting up and wiring any mobile entertainment system you can imagine. may i ask what kind of music you listen to and what kind of box do you have for these subwoofers?

if you have any questions email me at thadoggma420@hotmail.com

Is Sub Underrated for my Amp?


fuses wont restrict the current flow the amp is way too much for that sub. it may not have damaged that sub yet but it will. you might only need a 100 watts rms too run it.but you will need sowe where about 2000 watt sub too run off that amp

huge shared common space slot loaded box (size depends on sub 10", 12" 15" you need to clarify that please) the amp specs on earthquakes site say the phd5000 is rated at a max output of 5k watts at 1 ohm 3k watts at 2 ohm so, with 3 dvc 2 ohm subs you only have 3 options of which only 2 will be a usable solution:

1. 3- 2ohm dvc series at sub parralel at amp = about 1.33 ohms at the amplifier this is the best option to get the most power to the subs as each sub will produce a 4 ohm load then wire each one to the amp the amp sees 3 4 ohm parralel loads which = 1.33 ohm so based on the amp specs you would be close to 1200 watts per sub.

2. 3- 2ohm dvc wired in series at sub and all 3 subs series wired together very difficult to wireand will give you a 12 ohm load which is next to no power at all (not a viable solution)

3. 2- 2ohm dvc parralel wired to each other and then at amp the amp sees a 1 ohm load and makes 5k watts max but you can only (REREAD THAT LINE! ONLY USE 2 SUBS IN THIS WAY) WHICH GIVES THE MOST POWER BUT ONLY USES 2 SUBS
