My 620 watt power acoustik amp is on protect mode for some reason, and it is ran to two 10" subs. i need help?

If you sub is dual 4 ohm voice coil, you can get a 4000 watt amp (which will give you 1700 watts RMS at 2ohms). The model number is OW-BAMF40001D. Hope this helps.

Sounds like an over current condition. Your sub may be the problem. Does it go into protect mode when it cuts out? remove the sub and turn up the volume and see if it cuts out when you keep increasing the volume. If not, then it may be that the sub shorts out when turned up too much, kicking the amp into protect mode. If it still cuts out, then it may be the amp. Try another sub if you have one or borrow one from a friend.

this is usually an anti theft precaution taken where if the amp is tampered or attepted to be stolen it will shut down making it useless for the thief the only way to get them unlocked is usually by the people whom installed it for you or the manufacturer

Could not get a manual for you but did get the follwing specs. Hope they help.

Hello missywarden,

According to the specifications, the amp is capable of "tri-mode" operation, that is, running normal speakers on the individual channels while also powering a subwoofer in bridged mode.

Your sub needs to be a minimum of 4ohms and should be relatively efficient. I'd look for a sub that has an RMS power range of from about 75 watts up to a maximum of 250 watts.

The sub connects to the leftmost speaker terminal (positive - right channel) and the rightmost speaker terminal (negative - left channel).

It's not going to be a really loud subwoofer. The power is 360 watts RMS which will be shared by the normal speakers and subwoofer.

Hope this helps.

this is usually a problem with incorrect cabling you should check and see that all your cables are connected properly especially the ground cable thats what would normally give you a red light on your amp

Hello ace_sterling,

Not knowing what you have the SPL-620 driving or knowing how you have it wired, it's rather difficult to determine if it's wired "wrong".

I show the SPL DK2-620 as being a 2-channel amp with 150 watts output at 4 ohms, or 180 watts at 2 ohms. Even if the power is somewhat overrated, it should provide more than enough power for a set of standard 2-way or 3-way speakers, or component speakers with a separate crossover.

Powering one or more subs is another thing. You would get sound, but the subs would not be very loud. In bridged mode, the amp is only stable to 4 ohms. So if you are trying to power 2 4-ohm subs, the best connection would be 1 sub connected to each channel. If you are powering only 1 sub, then the bridged connection would be best.

Hope this helps. If it does, please rate as "FixYa".

If the amp goes into protect mode, it's likely due to shorted output transistors. To eliminate other possible problems, read through the following page:

Amp in Protect Mode - Troubleshooting

If the problems are not with the wiring, follow the link at the bottom of the page to the Amplifier Repair Primer page.

Let me know if you have any other questions.

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
