Question about Power Acoustik PS2-1200 Car Audio Amplifier

Amp getting really hot

I have a Power Acoustik PS2-2200 Amplifier and a Almani S5-12" sub.
Amp details:
2 ch
4 ohm RMS = 370 x 2
2 ohm RMS = 450 x 2
mono RMS = 900
Bridged Max = 2200
Sub details:
12" high output subwoofer
800 watts RMS
1800 watts max power

i have the amp bridged at mono RMS which is 900 watts. The sub is set at 1 ohm which is 800 watts RMS. i was wondering if it gets hot because the amp is 2ohm stable, bridgeable and the sub is set at 1ohm. is that the problem since my sub is at 1ohm and my amp at 2ohm? or is there something else i can do?

If depends on what the amp is rated to run. If it is only rated to run 2 ohms x2ch then it can only run 4 ohms x1ch. If you run it at 1 or 2 ohms that is too low, too much current, and it will get hot and eventually blow up under hard use. Some quality amps can live that way, and it depends on the sub and what frequency you are running it at. For normal use I would not recommend it. Wire to sub at 4 ohms x1 (or 2 ohms x2ch) for that amp if that is what it is supposed to be at, I'm not sure from your description. Also enhance cooling of the amp if you can, I run fans on mine if they have a heat issue. Warm is one thing, hot is another and not good for amp.

Well it is getting hot due to the amp drawing and pushing alot of current. try getting lower gage wiring for power to the amp and lower gage speaker wire.

    the ohms is basically how much resistance the subs or amp is. that wouldnt have much to do with the temperature of the amp. if you are pushing your system when u have it on that will cause it to heat up too.

I need to know how to hook up an alpine v12 amp 2 ohm i have two tens


Hi there,

This really depends if your 10" subs are 4 ohms each or 2 ohm - for this exercise, I'm presuming they are 4 ohm each.

You already know your amp can deliver 600W RMS (@ 2ohm), so you need to be careful you do not exceed the maximum RMS input power of your subs.

Normally you would wire subs in "parallel", which would reduce the circuit load to 2ohms - however, the 600W RMS power may be too high for your subs to handle.

In this case, it may be safer to wire your subs in "series" - this will increase the circuit load to 8ohms, which will effectively decrease the amps RMS power output.


Cheers,

What would be the best size amp to purchase for two audiobahn aw1200 subwoofers and two pioneer 4-way 6"x9"?


First, I would purchase the amp based on the subwoofers alone. Allow unit power to run the 6x9's unless you are planning a intricate setup. Things to think about when buying your amplifier. Always get an amp that offers an RMS output of 25-30% greater than the combined RMS output of your subs. Also, the stability of the amp to handle ohms loads (1, 2, or 4 ohm stable). If you have two dual 4 ohm subs you can get a 2 channel 2 ohms stable amp, or a monoblock 1 ohm stable amp. This will get you the most power and sound for your buck. There are so many amplifiers out there at different price levels, it's really up to you. Hope this helps.

I have a pioneer XL2-520 amplifier. I bought it used. So I didn't get the user manual and the sticker on the bottom of amp is not there.. So I was wondering how many watts (rms) in mono mode at 2ohms....


i think its a power acoustik amp im not sure that was a pioneer model. if it is apower acoustik the specs are

125 rms x 2 @ 4 ohms
150 rms x 2 @ 2 Ohms
300 rms x 1 @ 4 Ohms

You can only bridge the amp at 4 ohms dnt go lower than that

What size amp do i need to run 4 1000 watt pyle 10's bridged


well first of all you cant bridge subs... you can bridge an amp... and for 2 they are probablly not 1000 watts, make sure you understand RMS and what the sub can ACTUALLY HANDLE properly... i would get a 1000 to 1500 watt RMS that is RMS RMS RMS RMS amp not one that says 2000 watts MAX POWER cuz thats cheap ****... get a kicker JL hifonic alpine or something in that category that actually tells you the TRUE power output of the amp... then run those 4 subs in a parallel circuit so its like really only having 2 subs. make sure then these subs do not run less then 2 ohms at the terminals while in a parallel, then bridge these subs acting as 2 subs not 4 to your TRUE 1000 watt amp and you should have a good powerful system

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.

Lt960-4 power acoustik Amp 4 channels mono


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.

2006 12" Kicker L7 4 ohm


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

Amp getting really hot


Disconnect the speaker wires and the RCA jacks from the amp.

If it still gets hot, the amp needs to be repaired.

If it doesn't get hot, check the impedance of the speakers and make sure they're wired properly.

If they are wired for the proper impedance, check each voice coil with an ohm meter to make sure none of the voice coils are shorted.
