Sounds like you have fried your output transistors. They can be replaced if u have the patience and know-how. Also check the resistors near the transistors. Some of them may need to b replaced too. I fu replace the transistors and the resisitors are still fried, u run the chance of burning up the new transistors again. I usually just replace both items since it's not that expensive and I'm doing the labor. What have you got 2 lose?

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 12 inch audiobahn 550 rms 4 ohm coil ported box and a dual box with 12 inch subs they say 550 max wattas a piece thats it waht amp do i need to get atleast 80% of my power in bass


Get a 1200 watt 4 channel amp that's 2 ohm stable. Bridge 2 channels into the single 550W rms audiobahn. Use the other channels for each side of the dual box. Turn the LPF or Low Pass Filter on and vibrate down the road.

Amp makes noise. I am purchaseing a new amp


Hello termite440,

A mono amp will generally provide more power for subs. And for those Audiobahn's, you'll want something that will provide a minimum of 500-600 watts RMS to each, a least a 1000 watt amp. At the low end, something like the Alpine MRP-M1000 or the Orion HCCA-D2400 will provide 1000-1200 watts. I'd recommend the Alpine. For more power, and another $100, look at the Alpine M2000, or for another $250, the Rockford-Fosgate T1500-1bd.

Hope this helps.

550x2 subs....SPL z2x-820 Amp


Hello,

The 230 watt amp is a little small for your subs. They'll work, but if you are looking for max SPL, you won't get it. To push those Audiobahn's to their potential pavement shaking max, I would recommend an amp in the range of 500-600 rms (2-channel bridged) or 1000 watts rms monoblock.

Hope this helps.

Will this amp push my speakers


Whoa, I do belive your rating for your speakers are inflated. I have never heard of a 6X9 accepting 800 watts thats just rediculas, its more than my 12" sub needs. Anyways, if this amp is anywhere from 300 to 500 RMS watts you will be fine. Because the speakers are small they need very little wattage to reach there potential, usually less than 100 Watts each, and probably around 50. If you think about it most decks put out 50Watts max for each channel, because that is the max you can assume that the RMS wattage of the unit is only around 20-25 Watts of power per speaker.
