I got my capacitors out of the door now. My new kenwood HU allows me to adjust bass so many different ways now that I can get really decent sound with the stock door speakers. It's not an ideal set up yet, but it's a lot better than stock.

I'm still on stock amp. Rear subs are not thumping through the seats, but the overall sound is damn good now that I removed the caps. I plan to upgrade the door speakers with infiniti 320w set. I will report back how things shape up.

If the sound isn't better, I will replace or supplement the stock amp for the subs.

Stock amp has plenty of power with the new Head Unit
