I started installing my aftermarket Pioneer Premier HU DEH-P640 last night and found out that I couldn't use it w/ the BOSE system w/o rewiring it. I did a little digging through this site and several others and found that if I hook the remote wire up that it might actually work. So today I hooked the remote wire of the stereo to the power antenna wire on the harness and the speakers turned on! Sound quality isn't all that great and I'm sure a rewire would help this problem but I'm just happy it worked.
Now for the real question, are there any long term/short term effects of leaving it hooked up like this? I know one door speaker is already blown and I've got aftermarket replacements for it and I plan on doing the rewire in the near future. Could I potentially hurt something by leaving it this way for about two weeks? I want to drive it quite a bit here since I'm getting my new tires put on tomorrow morning but at the same time I don't want to start an electrical fire in the car. Thanks for any input!
BTW: this is on a 94 Camaro Z28

I've talked with several knowledgeable folks at work and at Mobile Audio (central Illinois' premier car stereo shop) and a similar opinion seems to be echoing.
Most feel the only real danger is of blowing the stock speakers because they aren't made to handle more power than the stock amplifiers put out. So as long as I don't push them too hard, they should be alright. Mobile Audio suggested that if I did want to keep the stock BOSE speakers with the aftermarket HU that I buy a special filter designed for this situation. Evidently this filter scales down the signal from the aftermarket HU so that the stock amplifiers can take advantage without being overrun. This filter also costs $56 from them and they keep it in stock. I figure for $56 I can buy another set of 6.5in speakers, rewire them, and still have better sound quality for the money.

Not only does this "filter" drop the signal, but it also increases the ohm load that the deck is seeing. Aftermarket decks are almost universally designed to run 4 ohms, as are after market speakers. What you are doing is esentially running an amp that is stable at 4 ohms at 1.5 ohms. The deck is overheating as we speak, guarenteed. It will burn out. It may be a week it may be today, but you will destroy the radio running it without either new speakers, or a bose integrator

Thank you for your input JJEXP. I'll just have to park the car until I can get the new rear speakers so I can rewire the system. I'm glad you said something or else I would have been running it that way for another two weeks or so. I definitely don't want to burn up that deck!

As a follow up, I ended up just putting the stock headunit back in for awhile until I can afford new rear speakers and the time to do the rewire. The car needs some more maintenance before I get to toying with the stereo anyway. It's no fun to drive around without a stereo!

I had my Pioneer Deh-7700MP in with the stock Bose system in place. It sounded fairly good for the nearly 2 years it was like that. Just last week I put a 4-channel amp in and ran wire to each individual speaker. Sounds better.:)
