I just did the same thing.
BUt now i wanted to ge ta little 300 watt subwoofer to work. I was thinking How much power does the Bose amp have. An if i could just use that amp for the subs insteade of buying a new amp
thanks.

:? What are you talking about? I can't understand your first sentence...

You don't want to use the Bose amp, you should buy another amp.

But if the amp is powerfully enough why wouldnt i want to us it?

Just did what?
Also what model car is this? Presuming from your SN it'* a 99 SSEi, you should add that to your signature.
I don't think the Bose amp(is it even Bose? or Delco? never looked at it) has enough RMS power to run a sub along with the speakers. Along with that thought there are probably a host of other issues to go along with that.
I would just buy a quality mono or dual channel amp.

You cant run the stock Bose amp on yoru sub/*. The cars you see that come with a stock sub usually have a stock amp that is designed to handle the Ohm load and power demands.

The Bose system was designed to give the stock speakers a little more power, not run a sub.

Keep an eye out for a deal on Ebay for a mono block amp that will match the Ohm load you plan on giving it with your set up.
