Yet another factory amp question

[Stew-2]

I searched but did not find the answer to my question.

I am replacing my stock tape deck and my 93 has the factory amp. I want to keep the existing amp in place for now.

The problem: as many of you know the factory amp's remote turn-on wire is 5v, not the normal 12v that every other radio in the world uses.

The question: Can you supply 12v to the factory amp's remote turn-on wire or will you fry it by doing so?

If it is not safe to use 12v for the factory amp's remote-on wire then how are people overcoming this? I do not want to bypass the amp. Is there a 5v source somewhere that you can use for this purpose?

Thanks, Stew.

You connect the remote wire from the amp to the remote wire on your HU. The factory amp should be bypassed because the internal amp in your HU will deliver much cleaner sound, and you don't risk screwing it up.

Huskyfan23 - You should just come over, you prob only live 5-10 miles away!

Well I know that that's how you connect the wires but what I'm not sure about is that the factory deck only supplied 5v to the amp remote wire and my new deck will give it 12. I am very nervous about doing that.

I know I would get better sound by just bypassing it but I do not want to do that right now.

You'll be fine. I never heard of the amp receiving 5V but when I did my first install I ran it to my new HU's remote wire with no problems.

Your last post had such confidence in it that I went ahead and hooked up the 12v remote signal and held my breath and turned the unit on. With the remote signal wire now connected I heard music from my speakers, cautiously I turned up the volume. After a few minutes I went back to the cargo area to sniff around for burning wires but I smelled nothing. I went back up front and played around with the radio for awhile and checked again - still no smell. So, I guess it's working ok.

Congratulations! It takes a few days before it blows up You'll be fine.

Were you able to get bass out of the subwoofer or just sound out of the speakers because I installed a new deck and the speakers work fine but the subwoofer does not. By bypassing the amp remote blah, is the subwoofer engaged and does it produce bass?
