Im trying to remove the back plate from a TANNOY TS 1001 subwoofer to replace the fuse but I cant get it off. Can any body help please.

Did you fix yours?

The fuse of my TS1001 blew, because the MosFET IRF740, another IC, and the transformer were shorted.
Called Tannoy who were not helpful and asked me to get to their authorised reseller/agent, as you cannot purchase parts directly from Tannoy. The agent obviously added a mark-up on the part.
Cutting long story short, I purchased the amplifier board for a TS801 to fit in my TS1001 because the BASH amplifier for TS1001 is no longer available/manufactured. The sizes of the amplifier plate were similar although the TS801 is 200W with 8" driver and the TS1001 is 300W with 10" driver.
I am now using a 200W amplifier with my TS1001 (Works well with the 10" driver).

I just got a Rockford Fosgate P1 12? subwoofer. It claims to have only 300 watt max. I guess I?m confused because I just sold a 10? subwoofer that had more watt max. Isn?t the point of the 12? to handle...

You are correct. The p1 12" is 150Watts RMS and 300Watts peak power handling.

Powering the subwoofer over 300W for a short length of time will heat up the voicecoil and you will blow the woofer.

The p1 10" (if that was your previous model) has the same power handling.

The purpose of moving up to a 12" is to displace more air.

It takes less power to move the same amount of air when you increase the cone area.
In theory - in a properly constructed enclosure - with the proper amount of airspace - tuned to the Fs of the woofer - a 12" woofer will have a greater output than a 10" with the same amount of power applied.

So, your 12" p1 will displace almost 1/3 MORE air - and should be louder than the 10 at the same amplifier gain setting.

Hope this helps clarify your connundrum.

I got an alpine apx 1300 300w and the protection light is turned on

Most likely there is a short in the output stage. This would mean changing the output IC's and most likely the damaged support compoenents and driver devices.

The Alpine service rep can fix this for you. Some serious troubleshooting will be required.

The cause of this type of faulure is usualy from the following:
  • Short on the speaker wires, either to ground or to each other.
  • Damaged voice coil or crossover causing too much loading.
  • Power surge due to poor voltage regulation.
  • Playing the unit too loud and having clipping (distortion) in the sound. This usually also damages the speakers.

500watts sounds about right to me,i wouldnt go any higher as you risk popping the sub and haveing a melt down in the coil section of the subwoofer.
