Jeff you are a treasure !!!,

You are just amaizing Jeff,you are right i do have a lot of amps,i have been buying a piece at the time for nearly two years now.My speakers consist of Mb Quart and the sub is A/D/S/ their top of the line .As far as the speakers go the 5.25" Mb Quart will go in the kick panels (where BMW put their NOKIA's-yes Nokia makes car audio stuff too !) and the Quart's tweeters will go in the doors ,again OEM location and the 4" will go in the back where BMW/NOKIA reside.So here you have it,and you know what this is going to be my biggest install yet,i even made my own sub enclosure out of oak plywood 3/4"thick and one side is made of 3/4"acrylic so the A/D/S/ will be visible from inside the trunk (just the magnet) and when the armrest goes down the front of the sub will be visible ,here is a touch of mine...i bought a 12" Kicker square grill (you know their solobaric,cast iron or aluminum...) and i installed on the A/D/D/,why 12" on a 10" ?,because 10" Kicker grill only fits Kicker subs,i even vinyled my own sub box so it matches the black leather in the car.For wires i bought top line Stinger (dream series)rca's,for power i have some 2,4,8,10 gauge from Monster Cable,power distrib. by Phoenix Gold,Crankin Power.For cap i have one 1 Farrad Road Rage cap.For speaker wire i bought 12 gauge Acoustic Research .Jeff what do you think of all this components,i think it should sound pretty good,it better it cost me a bundle,if you have any sugestions feel free to tell me,thank you so much,you helped more than you know,i apreciate your help,again thank you !

You have some nice equipment and I hope all that will fit where you want it to go. Make sure that you are isolating the RCA wires from any power source wires. I traditionally run my larger systems with the power wire running along the same side as the battery, the RCA wires running the opposite side and the speaker wires running down the middle of the car. The ground has to be a star configuration ( central point installation ) to avoid ground loops and keep the ground wire to less than 3 feet for best grounding possible. Also, make sure the ground is at lease ( if not larger ) than the power cable and scrape all paint from the ground point for a clean, solid ground ( use a bolt NOT  a screw ).

Don't cheap out on your installation when you start. What I mean is doing it right the first time might mean doing it the long way, but that also means only doing it once !! Take the seats out for easier access to running wires, take the carpet out if you can and sound proof the panels from possible rattles from bass. I like your speakers you chose and I think that you will need another capacitor ( 2 farad ) for the amount of power you will be using. I'm not saying that 1 farad is not going to be enough, but 2 farad's  will be more than enough but remember that more is better .

I have a large system going into the company car this year as well and I have been working on it slowly since I have other customer's vehicles to do while I'm trying to install mine. You gave me an idea and I'll post what I'm doing with mine and see what other members think of the potential system.

If you have any other problems while installing your system, you can contact me or post your problems. When you are done could you please email me some pictures. I would like to see the fruits of your labors
