[QUOTE="JasonK94Z, post: 7867392, member: 643922"] *Everything is fixed up now. Called AudioControl. Inquired about the LC2i LOC with their Accubase deal. Went ahead and ordered one after they suggested that would fix me up. Also tapped into my front speakers for the signal instead of the rears. Then made a call to Powerbass about my box. Awesome customer service over there. The guy simulated my box and my sub using my net volume. Told me to take the polyfill out of it. Hooked everything up today. WOW! The bass is huge now. Huge bass with the satellite radio and mp3's!! Thanks everyone who replied with advice and things to look for. It got my wheels turning in my head and made me get off my butt and start trying to fix this thing. Nothing worse than spending money, thinking your doing things right, and in the end it ends up *******. Maybe it was hooking it up to the front channels that fixed it, maybe it was using the AudioControl LC2i. Either way, its fixed, and the adjustments on that LOC do work! 2011 Dodge Ram 1500 Quad Cab Factory Head Unit Dash - Kicker tweeters Front Door - Kicker 6x9 midbass Rear Door - Kicker 6x9 2 way The Kicker speakers were installed in the truck as part of a Mopar/Kicker upgrade accessory. I built a fiberglass sub box to go under the right rear seat. It is about .65 cu ft and sealed. It houses a Powerbass L-104D 10" DVC sub. I have it wired up as 2 ohms. The sub is hooked up to a Alpine MRX-M50 amp which should provide up to 500 watts rms. I also hooked up a Alpine gain control knob mounted on the dash. The amp can use line level inputs and has auto on sensing, so I tapped into the rear speakers for that. Added polyfill to the box to help with volume (supposedly). The problems: First - the disappointment in sound of the sub. I listen to music such as Stone Temple Pilots. The sub doesnt hit all that hard with the kickdrum. The sub gets real "buzzy" sounding. I have the low pass on the amp set to 80 Hz, still gets "buzzy" sounding. Even lowered it to 60 Hz. Put in something like Black Eyed Peas, and the boom boom hits hard, but thats my wifes music, not mine. I have played and played with the setting on the factory head unit and at the amp, and nothing seems to make the sub sound right. I swapped the subs speaker wires around at the box and this seemed to help a little, but not very much. Why does it sound better 180 degrees out of phase? The excursion went from hige to much smaller with it this way. Second - When I shut the head unit off I get a horrible low frequency tone that is very loud and non stop. WTF? It eventually stops doing that after about 30 seconds. Also, I attempted to adjust the gain with a multimeter and a 50 Hz tone.
