I want to upgrade the speakers in the front of my 182 Cup. I have a kenwood head unit and hthe speakers will be running off this. Its 50 watt per channel. I want to replace the door speakers and the dash tweeters with kenwoods. I don't want to make any holes and I want to use the original holes. I also don't want to have to use big cross overs as I want to use the original speaker wire, but well aware this may ruin the sound produced. Any help would be great. Cheers
