so i havent had a setup for a while cause of my bumb self not setting it up right and blowing my amp and subs.. but i have been looking around a little bit and this is an idea. (and pointers or ideas will help). i got a 96 infiniti i30 same car as nissan maxima.. and im wanted to do 3 10's in the back.. sooo i found a 200amp alt for powerbasterds.com for 300 dollors. i think thats a bomb price for a highouptput alt for a import. and then put in a battery isolator to a seperate batt in the trunk. maybe a kinetik or something.. run 3 FI Q 10's in the back. but im not all sure what amps to push it. i really like the alpine pdx1.1000. getting maybe 3 of them or what would be a good combo of amps. also if i was to run 3 amps how well could i tune them cause i heard its hard to setup multiple amps to play good. it'll take some money to do this but hopefully soon i will have my boom booms again.
I have 3 sound splinter RL-I10's if you are interested. They are 500 watts rms but they can handle more. And you can use a pdx 1.1000 for 2 of the subs and a pdx 1.600 for the other sub. Or you could do 3 pdx 1.600 for each sub. Then you would be able to get away with an upgraded alt and one good battery up front.
what ohm loads could he be looking at i would go with a memphis 4k or saz3000d.. soulds like u have a bit of money to toss around(i hate alpine amps :D...)
