Are you using at least a 30V rated LOC with this setup?

If you are interested in going stealth, I’ve seen the amp mounted above the stock amp in lue of CD changer. Just purchase the stock left carpet molding made for the CD changer option to complete the stealth look.

hey , thanks I do have the cd changer option. I pulled out the cd changer tried to put the amp but the amp is too big to fit in it...
I was thinking to try and to put the amp in a angle on top of all the hdd drive and the stock amp.

I'll post some pics later. also when I tested the system I had the subs facing towards the openig of the trunk. when I have the trunk open it sounds loud but when I close it sound tends to drop, am I getting bass cancellation(phase cancellation)?

That should work, just do not abuse the bass adjustment and 100Hz EQ band in the iDrive as the output of the OEM amp can peak at more than 30V in bursts.

Try installing the amp under the rear shelf... leave some space for air circulation.
