I had my boss 2400 watt 2 channel amp hooked up in my car. I had one sub on each channel and one of my subs blew. I unhooked the positive speaker wire on the blown sub, everything was fine. Driving down...

If your amp started smoking, probably not. Due to your description, did the other sub really blow? I would hook it up to another amp to test it. It may have been a channel in your amp. As for repairing the amp, the parts and labor to repair will probably cost you more that to just replace the amp.

What makes the bass1500 stay in Protection mode????

Ok, usually a fluctuation in amperage trips the protection on an amplifier. To start, check your ground. This is typically the problem. Use a multimeter to ensure that the ground you have is good. Second is the guage of wire. Look at the fuses on your amp. Add them together and use that as the amp draw total. 50-65 amps from 13 feet to 22 feet run of wire requires a 4 guage. If the draw is larger, you may need larger guage wire. Also, match the ground wire with the power wire in guage.

Hello i just bought a power acoustik cpt1-4000d amplifier and we and a friend of mine were hooking it up and he accidently blew the 4 30 amp fuses in the amp. so we replaced them with 4 40 amp fuses and...

You shouldn't have replaced 30 amp fuses with 40 amp fuses. The 30 amp fuses were in there for a reason. You'll probably find that if you put the correct sized fuses in then it will work. If it doesn't then you have burnt out or melted something and it will need repairing.

Why want my subwoofer play like it's supposed to? It barely plays

check your ohm load on that audiobahn sub some amps run at an bypass or ohm load and then kick off if its the sub itself is not a 2ohm stable or 4ohm stable

Amp goes into protection

make sure the impedance is right for the amp you're using. If you're using a 4ohm amp and a 2ohm sud that may be the problem. It may be overdriving the amplifer which is bad and can cause damage to the amp. Hope this helps.

Is there a sequence for a protection mode on my amp

Excuse me I was completely confused here. Well protection is just a feature with amplifiers in order to ensure they wont' burn up if too much power is to them or if they are incorrectly wired. If the amp is going into protection there is a problem. More than likely you have the subwoofers wired up incorrectly. You have to wire them up correctly in the box before you hook them up to the amp.. If you leave them incorrectly hooked up for too long the amp will fry then it will go into protection for good. Not cool when your investment is fried because of a silly mistake. Go to and look about an eighth of the way down the page in a list there is a menu for subwoofer wiring diagrams.

I turned my 15" L7 kicker and smoke started to come out the box

As stated before, knowing the impedance of your subwoofer would really help the situation. Either way the link I have provided is to your subwoofers manual (Incase you dont have it)

But since you have said it has smoked, if it still works I recommend turning the bass boost down (Bass boost causes alot of heat within the subwoofers voice coil and even within the amp itself and should never be maxed out.)

Here is a link to your manual for the subwoofer.

So as a solution to your issue, keep your bass boost turned down. You should almost never need it if you have tuned your amp correctly (You have a very serious subwoofer there)

Consider yourself lucky if your subwoofer is still working without issues.

Protection light lights up for a second and turns off and the amp seems like it is not working. It is connected and wired correctly.

disconnect the speakers from the amplifer, and turn the system on again. if the protection light still is active even without the speakers hooked to it, then it is most likely that you have a blown transistor in either the power supply section, or the output section.

Either way, your amplifier will need to be serviced.
