How many of you know you can change the rear bose amps from the 50 watt to 100 watt amps..did mine a few years back after Gordon K. told me about it.

Lots more bass out of the rear speakers.

I saw a few amps on ebay a while back that were either 100 or 150. I called Bose to ask about them, and the tech said they were aftermarket amps. He recommended against using them.

You are actually the 1st person I have heard say they upgraded their amp watts, so where did you get them, and how much of a difference do they make for overall sound quality?

Well I was at Gordonâ€™s ZR-1 class in 02 and he told me about using 99 100-watt amps in the rears, in fact he gave me one and I had to find the other. I would have to pull one to find the part #, Anyway I called one of the Bose radio repair companyâ€™s and talked with them about it. I believe they where out in Oregon anyway they can take any C5 100-watt Bose amp and change the plug so it will work in the C4 box.

The amp is a bit larger than the one that comes in our C4s but will still fit. The depth of sound is much better and so is the bass. Hope this helps.

More power is alway better

I'm with you on the more power front Steve.

I will call Bose to check and see about any adapter that might be needed and look into whether or not they would do it if the speakers were sent directly to them.

I spoke with Bose Car Audio on Friday. They said there is no upgrade in wattage available, and further stated that C5 amps put into C4 speakers could cause damage. I told them about your story and that things are working fine for you, but he said they will not retro fit anything like that into a C4 speaker.

I will be sending in all 4 speakers to have a complete change out of components including the speakers and amps this coming week. The only drawback to using Bose is the turn around time which is running 3-4 weeks at present.

Jim,

Well you got my curiosity upâ€¦so I went down and removed a rear speaker from old blue..As you can see it is in fact a Bose 100W amp out of a 99-rear corvette speaker. No mods were made to the AMP plug. It was a plug and play and has been playing with no issues for the last 3 years and trust me I play it loud. As the amp was a bit larger, I only used the lower two mounting holes. I do think Gordon was right on, if you get an opportunity drop him an e-mail about this.

Now run that by Bose they can even check the part # 182670-0199 on the amp.

Some things in life you just have to find out on your own
