SOURCE: my amp!!

okay, 200 x 4 means 800Watts now that should be the peak RMS which is how it regularly works "STABLE" should be 400 or 100rms per chanel, find speakers of 100 rms to get e clean sound wave. If you can bridge it get you two 200 rms speakers.

The most common cause for an amp to go into protection is shorted output transistors. To eliminate other possible causes, read through the following page.

Hello GregV24CHOPP,

The Soundstorm products are in about the same category as Boss, Visonik, Pyle, and Lanzar to name a few. Somewhere between overrated and definitely overpriced for the quality you get.

Look into the Alpine MRP-M1000. RMS = 1kW into 2ohms (600 into 4ohms), YES 4 OHMS(!), real power. No, it WON'T do one ohm. But most of those claiming to are not CEA2006 compliant anyway and can claim any power at any load and advertise for whatever buyers they can attract for their bottom-of-the-barrel products.

The MRP-M1000 is currently on sale at Crutchfield for only $347. Awesome power, and very good sound quality, too. I'm currently running 2 4ohm MTX Thunders off of "little brother", the MRP-M500, and they really shake the pavement.

You have to spend good money to get good power, there is no way around that.

The only wiring configurations for 2 2ohm DVC subs result in 0.5ohm, 2ohms, and 8ohms impedance. Check the Rockford-Fosgate "wiring wizard" for the different diagrams.

Hope this helps.

I have 2 amps instalkled in my car one is sony 1200w 2 channel amp for speakers and one is solid audio f2500d for 3 subs my sound and every thing was good but suddenly from yesterday im having trouble when...


First disconnect the CD head unit from the sub amp and see if the other amp works. If yes, the problem is the wires to the amp, the amp itself, or the subs/sub wiring. If no, the problem is the head unit--probably an internal short.
If the other amp works with the sub amp disconnected, reconnect the sub amp to the head unit, but disconnect the sub wires from the amp. Try the CD player. If the amp goes to protect with no speaker wires attached, the amp is bad. If the amp is OK, the problem is the subs or sub wires. Hook the wires up to the amp again, but disconnect them from the speakers. Try the player again. If the amp goes to protect, the problem is the amp wiring. If not, the problem is the subs. Check the impedance of each sub using an ohmmeter to determine which amp is out of spec.
Please let me know if you have questions, and thanks for using Fixya.

Protection light comes on went the amp is turn on and it stays on for four seconds and then the amp turn on


Disconnect any speaker from the amp then re-power. If it still goes into protection, your amp needs serviced. Shorted output transistors most likely. And check your Sub for shorts as well. If the voicecoil on the sub is burnt, it will short any amp. If you can use a meter, check the resistance on the sub. Hope this helps

Sub cutting out


Check the 12v wire running from the battery to the amplifier. Also the sony explode is a garbage subwoofer compared to the Alpine.. sony (they say 1200w max but its more like 100w to power the thing) Amp could be going. Is the amplifier hot when running. If there is a burnt smell comming from the amp, its the amplifier

Memphis PR300.2 Amp protect light on


If it is not turning on your problem is it is not getting power. Check your fuses. The reason an amp goes into protect mode is usually because the subs are not wired up right. Make sure your fuses are good, you have a good ground, and make sure your amp turn on wire didn't come loose when you were putting the deck back in. As for the amp going into protect you probably wired the subs down to too few ohms and the amp you have can't handle it. Try hooking the subs up straight w/o bridgeing them and turn it up to see if it works. If you don't have problems with it then you wired your subs wrong.

Does it go into protect in the vehicle if you disconnect the speaker wires from the speaker terminals of the amp?

The amp probably has shorted outputs. Do you want to try to troubleshoot it and repair it yourself?

Soundstorm 1600 Watt Car Amp


Disconnect all speaker wires and signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.
