Audio system power output

Can someone tell me how much power the speakers on a 1994 GL1500SE can handle? I'm thinking of adding an amplifier to my bike so I can plug in an SD card full of music. It looks pretty straightforward to put a DP4T switch on the speaker outputs on the radio so that the speakers could be fed from either the OEM radio, or an aftermarket amplifier. I have a 100W amplifier and a 600W amplifier and need to know if the speakers can handle either of them?

I went and looked at the OEM speakers that I removed and they are marked 10W-3Ohm, so I wouldn't try either amp.
Quite a few people have replaced their stock speakers with Polk 401 & 501 with a foam baffle like I did.
They are rated 135W (peak) and 4Ohm.
Do a search here and you'll find quite a few threads.

Thanks Chris - my other option would be to use the speakers that came with the amps. The only problem is that the mounts that came with those speakers are made to use on the mirror stalks - but the Wing doesn't have mirror stalks so I'll have to figure out another way to mount them! Oh well,l I've got nothing better to do! :D

+1 on the Polk DB501. Put them in the front. Much better than stock, and capable of a lot more power. The speaker enclosures are so poor on the 1500, I doubt you'll realize any serious improvement. The enclosure of speakers is probably as important, or more, than the speakers themselves. Just my opinion, but lots of guys run amps anyway.

That's one reason that I put in the foam baffles. They are DEI and $10.83 a set here on Amazon.
I don't run an amp and between the speakers and these baffles, there is a world of difference.

I installed both Polk Audio db501's and db651's on my 2010. I left the OEM tweeters disconnected and have absolutely no issues with the output. Below are pictures of the db651's. I didn't use any baffling behind them. Your speakers are probably 5 inch so the db501's should fit.
