I have 4 15's I need to fit in my Altima! Kinda a wierd lineup but I got screamin deals so oh well! I need some advice on how to run everything! I have 2 Phoenix Golds XS2500's and a PPI PC2150. Heres my subs 2 15 inch JL Audio W-6's and 1 15-inchPBX PowerBass XSDv.2 and 1 Power Acoustik 15-inch FUBAR 15W(1000w RMS ones) This is how I was gonna set it up but need help! I was gonna run an XS2500 bridged to 2Ohm to the PBX and FUBAR!(1 to each bridged) than run the PPI to the 2 JL's.... What do you think? I have a cap too a phoenix Gold XSC1o at 1.0 farad but I know I'll have to either get another alternator put in or a Optima Battery! Which should I do? I havent hooked it all up yet because I just got the PBX & FUBAR but am ready to try and see if I can Blow Them! (MY EAR DRUMS) Any help with Box specs or what I should do or how to wire all this would be exteremely helpful! I have all the boxes singled out! So I can fit them in the Trunk~ Thanks again to all people who will offer help!

First off, you do NOT want to mix drivers like that. It would be the equivalent to running 4 different engines in your car with one on each wheel.

Second, set a goal for your system that you know you can accomplish and that will give you what you are looking for.

Just because you have four 15s, doesn't mean you'll be loud.

Planning and installation are the keys, and that's where you need to concentrate before moving any further.

Keep the PPI for fronts, sell the PG's and get a single 1000w@1Ohm class D amp for the subs. Keep the JL's wire both coils in parallel, wire both speakers in parallel, which will give you 1.5 Ohms and wire to the class d amp giving you about 450w per woofer. Sell the PB & the PA. Build a nice ported box for your JL's an amp rack and call it a day.
