Hey guys I am intalling a little system in my car and wondering how I should set it up.

Deck - Alpine 9855
Amp- Audison srx3
Front- Dls UR6
Sub- JL 10w3v2
Cap- Monster .5farad

Now my ? is
-if I run that amp @ 4ohm's is 75w a side enough power for the Dls or should I run the fronts in a 2ohm load to get 110w and the sub @ 4 ohm
-what gauge wire should I use?
-Also where is the best place to mount those tweets without butchering my door panels?
-should I run an rca from my sub out on my deck to my Amp?

Thanks in advance
