Okay I have a 2 channel 600 watt amplifier and i got it hooked up and i plugged my subs in and they are not pushing bass but instead the vocals like their is absoulutly no bass an it is really a 600 watt 2 channel power acoustik sterling amp it is not a Power Acoustik TS1440-2 Car Audio Amplifier
Re: 600 watt 2 channel power acoustik sterling amp
On your amp, there should be a switch (on the side probably) that has "LP", "HP", and "FULL" or "OFF". This is a switch for the low pass/high pass filter. Switch it to "LP" as this will allow only low frequencies to go to your subs, what you want. If you don't have that switch, go to an audio store or online audio supplier and get either a low pass filter, band pass filter, or a cross-over, and follow the wiring diagram that comes with it to filter out the high frequencies before they get to your subs.

Pace posted on Saturday, March 05, 2005 - 01:08 GMT Your subs are dual 4 ohm voice coils so if you want to bridge your 2 channel amplifier to your two subs then wire them parallel, meaning the + to + and - to - ( Do this to both subwoofers), Then run a wire from one positive and one negative on each sub and bring the two positives together and the two negatives together and hook both positives to the far positive connection on your amp and connect both negatives to the other negative on your amp,
This will create a 4 ohm load on your amp.
Although if it's a two channel and you have two subs it's usually pointless to bridge them because if you use one channel per subwoofer its going to be the same as if both subs were bridged. example) 800 watts x 1 bridged power of your amplifie (4 ohms) is the same power as 400 watts x 2 at 2 ohms.
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.
it can be used as a bass amp. if each pair of channels is bridged then you will basically have a 2 channel amp. just be sure to set the x-over's to lpf for subwoofers. I checked the power ratings, and bridged at a 4 ohm load will give you 250 rms watts per sub, so thats enough to run most 10's or 12's. there wasnt a rating for a 2 ohm load, but your amp should support it.
your only choice is to run the amplifier at a 4 ohm mono load - this will not reult in the amplifier making much power.
Positive on sub to Positive on amp.
Negative on sub to Negative on amp.
This is your only possibility.
Adding a second sub in the same fashion will result in a 2 ohm load, and your amplifier will run at its rated potential.

Remove the load from the amplifier (subs) and the RCAs
If the light stays on, there are internal problems with the amplifier, and it needs to be serviced.
If the amplifier works normally, attach the RCA's and power on again.
If it remains on, connect one sub, and then the other.
Your amplifier is a 2 channel amplifier rated at
60 Watt - 4 Ohm - 2 channel(s) 125 Watt - 2 Ohm - 2 channel(s) 250 Watt - 4 Ohm - 1 channel(s)
Your amplifier is not rated for a 2 ohm mono load. If you have Single voicecoil subs wired in parallel, you have a 2 ohm mono load - your amplifier will eventually fail.
first whats the range in terms of WATTS that your 12" sub can handle in 4 OHMS ? second , lets check the AMP , POWER ACOUSTIK 1800 WATTS , Now thats a lot of power to drive a single 12" sub speaker . your amp is 1800 watts , per channel is around 500 watts , if BRIDGE thats around 1600 watts rms for ONE channel , if your sub can handle that kind of wattage fine , but it will not blow the amp , what it does is shuts down , some kind of protection mode , it will come back on after a minute or so. I suggest to use one channel in stereo mode , or purchase another sub to use the other channel. i hope this helps AJ
