My wireless subwoofer keep cutting off and coming back on when the music or movie is playing


Some/most Sub Woofers have a Switch that turns them Off/On/ or Auto. On Auto, the Sub only turns on when there is a signal present. ( sound coming into the Sub ) When there is no signal, the sub goes into standby mode. Wireless subs may be made to be in standby mode as the default.

Is there a crossover in the ada885 sub box do i disconnect when using external amp


usually the external amplifiers have potentiometers that you can adjust called sub sonic and LPF. Find what your sub needs to be setup to and set the LPF to that frequency, usually 40-60hz.
Find the tuning of your box or the sub sonic frequency cut-off and set it there. usually 30hz and under, this will keep your subwoofer from unloading and damaging itself.

I have 2 10" Kicker Comp Subs


That amplifier is only rated at 150 watts at 4 ohms, or 300 watts at 2 ohms. Not a very strong amp to run 2 kicker comps. My guess is you have the subs wired wrong for your application. There are 2 types of subs, one is a dual 4 ohm, and one is a dual 2 ohm. Most people bridge these coils together and that cuts your ohms in half. For example. Lets say you have the 10cvr104 subs. Thats the dual 4 ohm sub. You wire the coils together in parallel, now its a 2 ohm sub. You have 2 of these subs running off of your amp, if they are hooked up in parallel, now you have a 1 ohm load, out of the amplifiers normal operation. Your amplifiers internals heat up really quick and there is a thermal overload, putting your amplifier into circuit protection mode. My suggestion for wiring your subs is as follows: for each speaker, wire the coils together like this- positive coil1 to negative coil 2 and negative coil 1 to positive coil 2. That is called running in series, and doubles your ohm load. Next, we need to wire the speakers together properly to hook up to your amplifier. For this, since the coils are hooked together, you only need to use one set of terminals from each sub. And take the positive from sub 1 and hook it to positive of amp. Take negative sub 1 and hook it to positive of sub 2. Take negative of sub 2 and hook it to negative of amp.

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.

When i turn the music up sub cut off blue light stay on red triangle cuts off


Hi, the amp is going into protect mode. You can either keep it turned down or possibly reconfigure the speaker connections for a higher impedance. If you tell be the model of your sub, I may be able to suggest a better arrangement.

I have all alpine speakers,deck,amp, and subs. My subs were working for about a year until one time i started my car and they keep cutting in and out .. at times they will work but then they cut off...


Sounds like blown subs, in the process of completely dying out, or a loose wire, possibly inside the box or from the box to the amp. Have your subs tested at a sound shop, or using a multi-meter, check for resistance across the sub terminals. An open line indicates a blown sub.

My amp keeps cutting on and off, it will play for a bit then it shuts off. What could cause this? I never had this problem before and I'm running the same subs


It might not be the subs causing your amp to cut in and out.

First, I would check your ground connection. Make sure all is tight and connected properly, both ground chassis and from the amp.

Second, check your 12v remote turn on. Make sure you are receiving proper voltage.

Lifestyle 30. sound stops, i unplug and plug back in and works for short time and quits. unpllug and plug back and works a short time and quits.


What you describe, sounds like a speaker short. Are you using the Bose wiring with their ends and no cuts in the wire? (splices) It's not too uncommon to extend or shorten a wire. The fastest way to find a short is to disconnect your speakers at the speaker. Be careful to keep the wires separate if they are not on plugs and turn on. If it cuts off (power) or says (protection) on the display that lets you know your speakers are ok and you have a short in the system or a wire. Next, disconnect wires at the sub one by one and test until it causes the system to cut off or short. Leave that speaker disconnected from the sub and test with all others connected. Now you've located the channel that has the problem. First just connect the wire again to the sub. if it cuts out, run a new wire from the sub to the spkr, for testing purposes make it a short wire if possible and test. If you need to use a Bose plug at the sub to test spkrs go buy one at Bose, don't cut your factory wire just yet. If a new plug works then cut and replace. Make sure you use electrical tape not scotch tape or duct tape. If it works fine, test the new plug on the old wire and see if it works. If it does your done, if it doesn't, run a new wire to the speaker with the new plug on it. If after all this and it still doesn't work. Sounds confusing I know, It's just process of elimination, that's how we do it in the field. If all your speakers are disconnected and it still cuts out, it could be the sub or the receiver. Take it to a Bose store and they can check each piece for functionality. If it needs repaired let Bose do it. Hope this helps.
