I am now resolved to the fact that I will only be satisfied with an amp for the four speakers(6.5 ones). Where are the most creative places that people stach the big 4 channel amp? The sub is in the trunk, and has the amp on it's back, but the other amp is tough due to wiring installations.

 

I hid my small 300/4 where my rear center console is, its under that.

 

Buy a smaller footprint amp and put them under the seats.

I just installed 2 kenwood xr series amps under the seats in my moms car. Those amps are tiny as hell and affordable.

 

I put my small amp in the place of the factory amp and satellite module

 

^me too

some people say that it may cause some ventilation and overheating issue but, i haven't had any issues for the past 3 years. I have an old 4channel rockford with the end caps removed.

 

I took out my spare tire and made a small amp/cross over rack.

I dont usually drive my car further than 30 miles, so im not to worried, plus I have 2 cans of fix a flat =)

 

Back of the seat, or under the trunk panel next to the spare tire (if you can get it to fit) or, if you have some decent woodworking/carpeting skills you can make it look puuuurty like I did.
