New system - Static depending on amp location
I just sold my old system and purchased 1 12" Alpine Type S sub at 4 ohms and the Alpine MRV-M500 (mono) amp. Threw it in a sealed box and it sounds awesome... would definitely recommend!
I have my amp mounted on top of the sub box. If I slide the box all the way to the back of my seats, in between the two rear 6X9 speakers, I pick up a ton of static and radio stations hardly come in. If I pull the box out towards the rear of the trunk, a lot of the static goes away and I can pick up all of the local radio stations. There is no static when playing CD's or my iPod.
My last system consisted of 2 12" Pioneer Premier subs with a Kenwood KAC-5204 amp and I did not experience this problem. The amp was mounted on top of the sub box as well.
I am running 8 gauge wire and my ground is attached at the right strut mount and words great. My battery wire is connected from the accessory terminal post right next to the battery running to the amp.
Obviously, I would like to keep my box against the rear seats to save as much space as possible in the rest of the trunk. That was the main reason I got a new system.
Any help is appreciated!

Only radio stations don't work then?

Yeah. Some come in decent, but others that I used to get with my old system are filled with static. Then once I move my amp around they come in better.

That's odd. Maybe it's the wiring interfering with the rear speakers, just like you're not supposed to run RCAs and power wire along the same side of the car. The amp itself shouldn't be doing this.

Is there only static from the rear speakers?

I have the power wire run along the drivers side, and the remote wire and RCA's run along the passenger side. I have read about high quality patch cable RCA's but would this fix the problem?
And all 4 speakers are doing this. Especially when there is bass.

If it's only doing this with radio, then there issue is in between the wiring and the radio antenna stuff. I know Aleros got the window antenna, so you might want to diagnose that first before swapping out RCA's or other stuff. Swapping the RCA's isn't going to help much because it's not a persistent problem (ie, it doesn't happen with CD's Aux, or USB).

The weird thing is, as long as I turn the amp "off" (where the light is still on, it's just not putting power to the sub through the setting on my Kenwood deck) the problem is gone. Once I turn it back "on", the static comes back. Last year I had the problem where my antenna booster signal wire wasn't connected.
Or, if it is turned "on" and I pull the whole box out to the back of the trunk, stations come in better. So could it be that the amp is some how interfering with the antenna module in the "C" pillar?

I thought Alero's had the Antenna on the rear window as lines like the defroster....
But yeah, I think that may be the case, is the ground interfering with anything remotely close to the antenna?
Better yet, where is the amp grounded?

The antenna itself is a part of the rear window. But there is an antenna module/booster that is in the right side "C" pillar.
My new amp is a class D amp. My previous amp was a class AB. I'm not sure if this makes a difference or not, all wiring is exactly the same and connected the same way.
The amp is grounded on the right strut mount. Which is close to the "C" pillar.

I started having this issue myself with new subs. Amp is on the side of my box. Grounded to seat bolt. When amp was on driver side of box I had no issue. Now that I turned subs around so amp on passenger side I get bass static too only with the radio. Since we grounded in different spots I don't know if that's an issue at all. My amp is also class d.

Ground on the driver side seat bolt and keep the amp(s) on the driver side. I never had an issue there. That is if they are a class D amp. If they are anything else mount them anywhere.
