I have the same subs. i am running a total 500/1. i would say not a good idea, just today i was listening to bass mechanic and i could smell the voice coils heating up. so probaly a 300-400 watt amp would be good. just make sure it is a true wattage amplifier. not a cheap amp. pioneer amps that walmart sells are actually good amps.

Can i connect a subwoofer to my marantz pm 66se amplifier


Ideally you would use a signal processor between the source and amplifier/ new sub, but if you have multiple sources the easiest way would be to run an active sub (with an amplifier built in) from the TAPE OUT of the amplifier.

Have a look at this: http://www.superfi.co.uk/extras/BandW/BW_ASW610_manual.pdf

Figure 5 illustrates what I have described.

I have two 12' kickers, will a x-plore 1000 watt 4 channel amp work well with it?


It all depends on the wattage of your subs. you need an amp more powerful than the both subs combined. For example. for 2 500 watt subs, you'll need at least a 1200 watt amp. amps should never be truned up to full power, 80% max as they tend to blow more quickly and overheat when on max. ideally you want an amp over the total combined wattage of your both subs so you dont need your amp on max for the best sound for you subs.

What is the best adjustment for a Nitro BMW 481 with one 12" Memphis subwoofer?


First you need to determine what kind of subwoofer it is and by that i mean, is it a dual voice coil subwoofer or a single voice coil sub woofer.
Dual voice coil(DVC)
Depending on how many Ohms each voice coil is you will have the amplifier drive a specific load (4OHM stereo (75 RMS x 2) 150RMS total power / 2OHM stereo(100RMS x 2) 200RMS total power) Connect each voice coils separatley to each speaker output of the amplifier for this configaration. Always making sure that the + & - of each voice coil go to the coresponding location of the speaker outputs of your amplifier.

If your sub woofer is a single 4OHM voice coil then your cables should be connected to the coresponding location on your amplifier which states "BRIDGED" It is marked clearly on the speaker outputs of your amplfier.

If it is a 2OHM then do not connect it to the amplifier. The specific amplifier is not stable at 2OHMS bridged and will most likely get damaged if you try to operate it at that OHM load.

IMPORTANT:
On the side of the amplifier where the adjustments are there is a switch that indicates X-OVER. (LPF/HPF/FULL) Make sure to set it to LPF (Low Pass Filter). (not doing so can damage the subwoofer)
On the left hand side of the X-OVER there is the adjustment for the LPF (30-250) the best setting would be at the same frequency that your speakers stop
(example):
If your speakers have a frequency response of 60Hz to 20KHz then setting your LPF to roughly 70 to 80 will be ideal. The rule is that where one speaker drivers frequency ends, the other must continue in order to complete the full range of audible frequencies.

if you have any more questions feel free to ask.

Need wiring diagram to connect speakers.


  1. There are many ways to wire subwoofers and amplifiers. The ideal is to match subs, amps, and their relative impedances to maximize their power capabilities. While not totally inclusive, the following diagrams should be helpful in determining which wiring option will work best for you: http://www.crutchfield.com/S-jXlGCwReN8E/learn/learningcenter/car/subwoofers_wiring.html

I just need to know the best way to hook my amp and subs together. i like a lot of bass. i just bought the subs and yhey dont really sound any diffrent. should i get a new amp.


Hello hembreegerry,

If you like a lot of bass, you definitely need to consider another amp. The SP2X-300 is only rated at 170 watts RMS into 4 ohms mono. That would barely be enough to power one small sub. You do not specify what brand and model your subs are, their impedance, or their power handling capacity. But for any subs, your best power solution is to add together the individual RMS power handling capacity and select a monoblock amp that provides close to the maximum at the impedance they will be wired to present. For example, if your subs are 4 ohms and have a maximum RMS of 250 watts, you would want an amp that outputs abour 500 watts into 2 ohms (2 4 ohm subs wired in parallel = 2 ohm load). An ideal amp in that example would be the Alpine MRP-M500 which outputs 500 watts RMS into 2 ohms.

Hope this helps.

Anyway to bypass my Bose Amplifier


not too sure what you are trying to do but just buy a aftermarket deck..for example for 100 bucks jvc has a nice deck with remote that plays mp3 and even has a jack right on the faceplate for a mp3 player.then throw your subs in the trunk hook up the amp and bingo banging beat.if u have the aruroa with the battery under the back seat its even easier

OEM gm stereo


If your amplifier has what they call High level inputs (basically inputs on the amp that you run the speaker wires from your radio into), you can splice wires from where the connectors are on your rear speaker(s), still leaving the speaker hooked up, and use those as an input into the amp. If your amplifier does not have high level inputs, a convertor is available to turn an audio signal from your radio output speaker wires ( spliced in just as above, leaving the speaker hooked up), into an rca output jack. Or the best thing to do would be to buy another say 2-4 channel amp w/high level inputs and rca inputs and outputs, and run your rear speaker wires into the amp. Then you'll be able to run the rca cables out of that amp and into the sub amp, and you'll have the new amp to power your rear speakers or rears and fronts. That would be ideal. But, A convertor is your best bet. Got em at best buy, circuit city, etc. Hope this was helpful.

What amp to use


recommended maximum for the sub boxes is 1600/800 here is the link to the manual if you need it; http://www.kicker.com/06/tech-support/manuals/manuals/2007/2007%20CompVR%20Box%20d01%20Web.pdf If you really wanted to get the maximum from your subs then a zx750, or possibly a zx1000 would be the ideal choice. Either amp you suggested will work, but you will have more fun with a 750 which should do fine. Hope this helps :)
