Whats up everyone, will be posting pictures later and showing my install of a Rockford Fosgate r250x4. Running brand new C&E 14ga. copper wires back to the amp from my 6.5" Kicker CS54 door speakers and wrapping the doors with FatMat so I'm pretty excited. Install will be in the upcoming week. I believe the speakers rated output max was 75w and the amp bridged was rated at 100+ so that's plenty for door speakers. Let the fun begin! :th_woot:

More pics and info coming...

Considered the P400-4 amp by Rockford Fosgate but figured you know with that kinda power you might as well be doin competitions lol Just wanted something cheaper, smaller and plus eventually I'll add another mono amp pushin a sub. But thats down the road yet :p Gotta save a little for that lift^^going uppp^^

Lol no reason at all, got the wire cheap and its quality copper so works for me! Of course I considered a sub setup first but didnt really wanna spend the money on subs and box design etc. Ive had lots of larger setups with over 4000w but definitely just want something clean and simple for this truck. Plus my door speakers have been clipping so amping them should stop that problem giving them the juice they need first!

Got the amp and speaker wire in the mail and prepping for the install tomorrow. Trying to figure out how I'm going to run the new speaker wire through the door boots into the cabin. Looks like it's going to be a huge hassle but worth the effort lol any tips running the wire trough the tube into the door? I've considered pulling with a clothes hanger lol

The stock wiring is plenty unless you just want to change it, which is a pain with the door plugs. I have 100w rms each 6.5"s in each door wired to an audiobahn 2200 hjc turned down but still enough to easily clip them on clean power and just wired to the dash then through the stock wires

I'll take a look at it tomorrow and see what I wanna do, prolly will just use the stock wiring and run them back to the amp. Only would want to change to the new speaker wire for cleanliness lol either way just excited to have another project. Thanks for the pics BigR, those were what I was looking for but not wanting to pull the door lol

My brain keeps visualizing the signal feeds when you say running wire to the amp.

When I think for a second I of course know what you mean....but it's not following the current path in that direction. I know, mr. technical. Then again, I get paid to make sure I know which direction things flow - so I'm notice things that pretty often. My job has definite to's and from's.

Finally found the time to go through and install the new Rockford Fosgate 250x4 amp! Install was a breeze, decided to not take the time and run new wire from the door speakers to the amp because I didn't want to deal with the door boots. SO its a simple setup taking the existing speaker wires and wiring them back to the amp. Of course making things look clean in the process hiding the wires lol Also the amp is finally giving the speakers the juice they needed so no more clipping :th_woot: Overall I would say this amp made a world of difference on sound quality, like being at a concert. However for them being 6.5" door speakers obviously the bass isn't by no means incredible but I am impressed with these Kicker CS54's. Didnt feel like installing the FatMat today so saving that for the weekend probably when I install an Alpine MRP1000 amplifier for the final sub touch to make it sound beast :drinking28:

Now I'm just dealing with the dreaded alternator whine, any tips to rid of this? Ground Loop?
