Hello all, I've been in the car audio scene for several years now. I started out with some cheap pioneer 12's, moved up to some MTX Thunder 8000's, 12 inch with a 1500 watt amp. Had them for a little while but just could not stand the way the bass sounded on many songs. The main problem was they were not loud enough, and had problems with non stop bass. So I moved on to 2 Rockford Fosgate Power HX2 12's. 2 Rockford 1050's, rated at a little bit over 1100 watts a piece, a Rockford dry cell battery, and 2 Fusion 1.5 farad caps and an Alpine head unit, just couldn't get into the Pioneer head unit i had b/f, skipped too much and even scratched my cd's. All my wiring is Fusion speaker wire, 0 gauge and a little 4 gauge. I had all of this in a Tahoe in a 5.5 cubic foot box tuned to 35. The highest I hit at a sound comp was 150. I wrecked my Tahoe and moved on to a 2001 mustang GT, mainly b/c I got a great deal on the price. Since moving to the mustang I upgraded the Alternator, not to a really high performace one but I got 30 extra amps on the stock. I moved all the equipment over except the box, switched to a sealed box, now I'm down to 141 dbs. I'm looking for some new subs, b/c I would like at least the standard 1 year warranty, obviously with this in mind i'm only looking to buy for an authorized dealer. So no you can get these on ebay, for cheap or anything like that. The main reason for the new subs is the fact i'm afraid i'll blow them at a comp and be screwed and get nothing out of them now that my warranty is up on them. I'm not looking to upgrade my battery, alternator, caps, or amps anymore than they already have been. Also keep in mind my truck is pretty filled up and I only have about 4-5 cubic feet before displacement to work with for a box. My other option is to get a ported box for them, which i'm looking into, however if I went that route I would just assume get some new subs to put in the box.
Kicker and Audiobahn are out of the question. Got a buddy with 2 L7 12's who hits 151 at sound comps(he is an installer at a Kicker authorized dealer.) 2 of my other friends also sport kicker subs, 1 has 1 12 Solo X hits about 154, 1 has 2 15 Kicker comps, hits 140. My other really good friend has 2 Audiobahn Flame Compression subs, his number is 143. Obviously I would like to stay away from those brands.
Let me narrow down my choices a little bit, however if anyone has a sub not mentioned that they fill would do the job tell me about them. I could get some fiberglassing done and put in some 12w7's, I also saw some 10w7's at the local shop I could get in, in indivual ported boxes. The 12w6v2's in a ported box interested me too, but they don't seem to get loud enough for my liking. I could go for some mag's, I would prefer the 15's, but then again space is limited, so the 12's may be more realistic. Another local shop said they would like to(and what shop wouldn't, lol) try and get some Diamond Audio TDX? 15's in there by sliding the box in through the opening behind the back seats and have them fire upward. They are 1600 watts RMS but they hooked a pair up to 2 1100 watt amps and they wang pretty good. I was also looking at some DD9500 series, but don't know their RMS. I would love to put some XXX's back there, would like the 15's but again space is limited, anyone heard XXX's with about 1100 watts on them? Again, we have lots of sound comps in my area so SPL is a premium, I would love to out pound my friend with the solo X, but then again I would like it to sound better than his too. Like I said i got about 4-5 cubic feet before displacement, however with fiberglassing, or cutting out the carpet of the truck will give me 2-3 more cubic feet. We did those calculations at the shop I bought my system at. Price is not a factor, performance is.
