Bridging a Head Unit?

[stocktires 10+ year member]

Is it possible to bridge my HU? I want to run a set of tweeters off of my deck, but it only puts out 18rms. Most tweeters need 30+rms. My door speakers are run off an external amp, so the power from my HU is just being wasted. I would think the answer is no, but Its worth asking. Its an Alpine 9825

Every set of tweeters I'm wanting to buy is at least 40 watts nominal.

Just seems like it'd be way better to run that instead of the 18rms coming out of my HU. Would I be able to tell the difference?

But since you say that HU shouldnt be bridged I guess I dont have a choice

Have you talked to the tweeter yet? did it tell you that it needed at least 30w? I think its being selfish //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
