Hello all I have been a lurker around a few forums for a long time and not new to car audio, but i recently got a new car (2001 audi a4) and want to take it to the next level. So I have been doing alot of searching and reading (hours a day) and posting a few places but i find myself reading posts here often so i thought i should just ask and get your opinions.
Enclosure My car has a large trunk but i often use all of it for work, road trips etc.. So I want to build and install fiberglass boxes in the pocket behind the wheel wells I have measured rougly and one side limits me to about .65 so my first thought was a pair of 10's one on each side. Recently though I have been thinking about a single 12 with the side that has more room I could get at least .8 if not a full cube.
Power I have already purchased an alpine mrp-m2000 the car will be wired with knukoncepts ofc 1/0 I will do the big 3 and i plan on the biggest agm i can fit upfront i may tuck a small agm some where in the trunk to if it turns out to be needed. stock alternator is a 120 from my research there is a bolt on oem 140 but i would probably go straight to swapping a water cooled 190 from a vw touareg if I needed to mess with it.
goals / benchmark being sealed i am obviously not trying to set records or do anything crazy but i want to build the best system i can with my given constants. I like my bass to hit hard and sound clean / accurate I like to really feel it. I basically want to get as loud as I can sealed with it still sounding good I don't want to be loud just to be loud. in the past I have preferred 10's but I think some of that was lack of proper set ups I had a 10 l7 in a factory kicker slot ported box on an alpine m850 in my jeep and I was pretty happy with it for what it was. I tried a 12" l7 in a slot ported box and went back to the 10 but the 12 ended up in my sti on a jbl 1200.1 at 1 ohm and I thought it sounded ok but not great. my truck has 2 10" alpine type s in a sealed under seat box powered by a mrx m110 and for the money i'm into it (about 300$ for everything) i'm content with it . my favorite set up is the one i did last which is 2 10w6v2's in 1 cube each gross on a jl audio 1200.1hd forward firing (her choice) in the back of my gf's bmw. I love the way it sounds but want more.
Music I listen to mostly rock and rap / hip hop with a little dubstep occasionally cause i like the bass lol
Budget less is better but i will save up or by used to get what i need to do it right the first time
previous research this has led me to consider the following subs fi xv3 or ssd for dual 10's a q for a single 12. I'm not gonna lie I really like the look of the fi's but i know that shouldn't matter but i'm a sucker for carbon fiber and color matching things. ssa gcons for dual 10 or a icon for a single 12 but that would be a lot of amp on it. one issue I ran into when searching is I find a lot of great reviews or comments but they are so old that a new version (or multiple) of that sub has been released. if any one has links or suggested reading feel free i will absolutely read it.
the rest of my system I will be running hertz hi energy components in a 3 way active set up with mid basses in the rear doors and everything tuned on a dayton dsp. The rest of the amps will also be alpine mrp either a f300 bridged to the mid bass and a f600 to the mids and tweets if I can find one or 3 f300's bridged
thanks in advance for any help, chris
