Next remove the center carpet, just lifts straight out.
Last, get to the battery box, Turn the plastic knob and pull the top back and lift off. Done.
I had all front and rear gains at minimum. I set the subwoofer gains up 1/5th.
X-over points: Front and Rear high pass @ 160hz 12db/slope. Subwoofer low pass @ 140hz 12db/slope
Turned the car on to listen for alternator whine....No noise at all!
Sounds amazing. Everything is crisp and clear. It gets loud and stays clean. Midbass punch is more pronounced. And best, the OEM subwoofer actually hits some lows.
The OEM speakers actually sound really nice. Better than some of the aftermarket brand that I paid $$ for in my other cars.
The only thing i worry about now is the how long the speakers can handle the extra power. My thinking is maybe forever since the power is much cleaner and I wont be clipping.
Best audio upgrade for under $500.
Update, after a week of listening. I heard the mids struggling a bit and I heard a gap in the frequencies. The bass was also a bit low for highway speeds. So I moved the x-over points to 180hz and 200hz. Then I moved the subwoofer gains up to 1/3. This seems to help much.
I ordered an Alpine PXE H660 to flat line the frequency curve....Install coming soon.
