I would love to upgrade my HU but money is tight. The other thing is I love the steering wheel controls and I have absolutly no way of upgrading the HU and buying the the steering wheel sending unit. We would be talking over $250 for a plain setup that would probalby blow the factory speakers so they would need replace soon also. I don't have that much money and there is no way I can go with out toons.

I plan on installing a switch for the rear amp. I want to be able to turn it off with my kids in the car. I would like them to hear beyond the age of 10. That is the whole point it putting speakers in the rear doors.

As I was writing this I just thought of something. How about it I installed a dual switch for the rear speakers and subs. Flip the switch one way and the subs come on and flip it the other and the door speakers come on. With this setup there wouldn't be dual speakers coming off of one set of wires which means no ohms to divide.

Do you have the gain control slider under your head unit? If you do, i'll tell you exactly what you can do, and it'* exactly what your looking for.

errr....hmmm....

yeah.

I"ve always cheated and used the antenna signal power from the HU to power up and down the amps.. pending on the amp it might be somethin to consider ( money concious like me )

Hey Drifter,
Nothing wrong with using the power antenna wire to trigger the amp. It'* right there and does the job nicely.
Parallel. If you have the gain control below your radio let us know, and someone can show you a quick & easy way to add the amp & sub.

I don't have the slide controller, just the standard factory HU with CD player and Treble and Bass, I don't even have the equalizers.

even the factory HU should have FADE and balance. You can control those rear speakers by fading all sound to the front, if you have your amp powered off the rear speakers anyway (for audio) when you fade to the front the subs should quiet down too eliminating the need for a "switch". Just hook the remote turn on to the power antenna? (does the factory head unit have one??) feed off the head unit, or to another fuse that only comes on when the car is RUNNING (so you dont drain the battery while listening with the engine off). Another thing you could do is hook the subs and speakers you are planning on putting in the door up to the amp, in the case that you dont have a fader one switch will turn them all off. After you calcuate how much time you are going to spend on this project.....
