Too much hassle to ship it back. I'll make it work. I'm not in an audio contest, it should be fine.

I would just do as I stated before, "use the pass through on the sub amp to rears". Your sub control on the HU will affect both of these, but its not really a big issue if you tune down the frequencies on the rears. Let us know how it sounds.

so i was just test fitting my deck and found out the guy who installed my sub used a line out converter. (like this one http://www.sonicelectronix.com/item_...AC-SOEM-T.html)

so i figure now that i can just keep the line out converter in place and use the 2 preamps from the headunit to the 4 channel amplifier.

much easier

so i got the deck all wired in today, i am pretty happy with it. install on the amp took way too long though. I was trying to figure out why the power light wasn't on on the amp, so i grabbed a multimeter and checked all fuses and voltages. everything was ok. after 2 hours of troubleshooting the solution was i had a dead battery. it must have just had enough juice to power up the deck which is why i never looked there before. stupid mistake

tomorrow i will be wiring the speakers in the door, hopefully it goes a bit quicker.

Hogan

i got the speakers wired in, changed it back to the idea of using the mono pass thru.

i have some mad whining coming through the speakers. any ideas? i still have a line out converter in there which is serving no purpose so i have to take that out tomorrow ( its still wired in.)

when i only had installed the deck it all worked with no noise so it has to be something to do with the 4 channel amplifier. im stuck

There are typically only two reasons you will have noise in the system... either a bad ground... or your RCA cables are too close to a power cable (doesn't have to be the power cable from your amp).

Questions..
1. Does it sound like alternator noise? when you rev the engine does the whining changes?
2. Do you have RCA cables running next to your amp power cables in the door sill?

Unplug your RCA cables from the amp and see if the whining is still there

^^hes got it down packed. my buddy's amp was making a whining sound brand new just came out the box. I thought it was the ground and rcas to till finally we unplugged the RCAs to try a new pair of the noise reducing ones and I noticed it was humming. put your ears close to the amp to verify if it is.

it does get louder under acceleration it goes a higher pitch.

i will try moving the rca's, thanks

Hogan

i tried to make a better ground connection, but it made no difference.
i disconnected the rca's going into the amplifier and the whining stops.
