Ok, so I got the other amp wired up to the new 6" fronts. All I can say is it sounds amazing. The stage completly shifted to the front, and there is plenty of bass. Heck I need to adjust the gains back down! 100W @ 4ohms going to infinity perfect 6"s
My problem became that I'm using a 4 channel amp, 50w/channel to power my rears only. The problem was a horrible 'WHINE' when I tried it. It was wired to the rear RCAs, and output was to the rear speakers as they were wired before. So I looked at the book a little
and it said to wire it from the fronts... Ok, so RCAs go to the front, and shift the speaker wires to the front channel. SAME outcome. It wasn't engine whine (more on that below). Then I actually read
the book... It has the RCAs going to the front, and then bridged.... DOH. I dont really want to bridge them, thats 100W RMS and my speakers are only rated at 50W RMS. I have the gain at ~1/2 or so and faded toward the front now. It'll crackle above 16 or so on the Volume
My question is: Is there a configuration that I can use so I drive the amp with the rear RCAs, and only have one speaker output? Would it be as easy as getting 4ohm resistors and wiring them to the 'empty' speaker terminals so the amp thinks its powering a speaker? Or should I just upgrade to 100w speakers...
I'm also having a problem with engine noise. RPM dependant of course. I think I have it licked, but want to doublecheck. Everything was fine with the 2 sets of RCAs when they were wired to the single 4 channel amp. The problem started when I added the second amp. I think
its because I am using two seperate ground points. Would 2 ground points cause engine noise?
