I talked it over with him. We've decided on doing both. Budget is up to 3500. We are also just sticking with two 18's 2 18" Audioque HDC3s D1 Audioque 3500D @ 1ohm Kinetik 1800 under hood, Kinetik 2400 in back 250 - 300amp HO alt (DC Power, Mechman, Ohio Gen, DB Linc, etc) Knukoncepts Kollosus 1/0 awg wiring(big 3 upgrade and for wiring batts and amps) For the headunit we are going with IVA-W203/P1 by alpine.

A buddy of mine is looking to upgrade his audio, and between him and I we are trying to get some ideas about what to buy. He has a new(ish) (2004-2006 probably) cadillac escalade. Not positive of the max dims, but I can get exacts if necessary. I'm just assuming similar to most other large SUV's. He is running his stock head unit but willing to upgrade if necessary, which will most likely happen. He is considering (2) 18's or maybe even (4) 15's or 18's. I am looking for suggestions as to what subs and amps to buy, but even more so to what else is necessary to accomodate such a large amount of RMS. He is running his stock alt. So, besides the Big 3 which I know he will need, what should he be considering as far as HO alt, bigger/multiple batteries, etc? I am leaning more towards (2) 18's since I really don't think he's considering all of the extra work (4) would be. So, any recommendations on subs/amp, and any info as far as what will be required to do this? Thanks. EDIT: Oh, and I forgot to mention. Budget is up in the air. He got bent over on the two kickers that he has in his truck now for like 2 grand for two 15 inch l7's. Lets say between 0-2000 to start.

Eventually I think I'll upgrade. For now I'm keeping it at just one.

Looking forward to getting it installed. I'll let you know how it sounds.

Box is 2.14 cubes tuned to 33.6. Has a 2" wide port with 26.5 sq. inches of port area. 37.25" wide, 14.75" high and 10.75" deep. EDIT: I'm not sure what Alpines exact specs are but IIRC recommendation said 1.75. I am working with a guy off CA.com who is building the box and he said with all of the SWR's he's worked with, 1.75 chokes them a little bit and he suggested going a bit bigger so we decided on 2.14 cubes.

Thanks, I'm going to need it. The guy "helping" me turns out not to be as car audio experienced as I thought. I asked him to take a look under my hood to see if the spot I found to get my power wire through my firewall would work and he responded with "Dude you don't even need to go through the firewall I have mine running through my door insulation"

Ok, thanks a lot man I appreciate it.

Thanks for the quick response. Would this be the most efficient setup? Is there other alternatives to consider or would this one make the most sense?

(1) Alpine SWR1242D (1) MB Quart DSC1000.1 Sub is 4ohms with two voice coils. The amp also has + + - - option. So, should I wire each voice coil separately and voice both sets of + - or wire the vc's together and just use one? Thanks for any advice, I have no idea lol.
