But do u really think it will be loud enough in a BMW btw bmw's have that firewall sheet in the trunk.

my old cutlass ciara was like that but it did go loud for 400watts rms try and get something over 1000watts rms and you should be good even with a firewall you should still hear it for sure

unless you are willing to cut holes in the firewall lol

Do u know that cost for cutting holes and will it bring down market value of the car ?

My friend has a Beemer with the firewall. 400wrms on one 12" IDQ sealed. He is not heard from a block away, but sounds nice in the car. Sounds like what you really need is 1 or 2 12" or 15" SPL subs ported in around 3 cubes or more. Choices you got on subs are excellent. Gotta figure out what sub/s you want, and at what impedance they will run, and then get a Class D monoblock which puts out around 1500 wrms. I recommend getting a used Sundown 1500D, and spend the rest on new sub/s. I would not get used, cause they may have been beaten to death already. If you can get your hands on Sundown amp, you will be extremely happy. I have one - what a beast!!! Sounds extremely clean too, not too big, and super efficient. Then you need to get sub/s to run at 1 ohm. You can even run this amp at 0.5 ohm, but for the sake of your alternator, I would not try it. Amp also excepts up to 18 volts. If I had $1000 for amp and sub/s, I would only get the Sundown to run them if I wanted loud bass.

My friend is using this amp right now on an 18" Focal KX in an Impala, and he has enough bass to collapse a lung, and then some...

i wouldnt be able to awnser that one lol if it was an old car i would say who gives a shit just do it but since its a newer car i beleive i would check on that . im pretty sure it wouldnt hurt the value and to cut the holes you would have to find someone with a plasma cutter or just use a jig saw. but you will have to remove the rear seat to do this somehow

I don't know how ridiculously loud you want it, but I would get that Sundown amp with two 12" IDMAX subs, cause I love SQ. This will be loud and very clean. Chris at S & S Electronics in Scarborough has them on amazing sale, and you can get both brand new locally for $600 plus taxes I guess. This would be my pick at the moment. IDMAX's will look sweet in a Beemer.

Then you can get another used 2 or 4 channel Sundown to run a component set in the front, and possible rear fill.

How about two Premier TS-W3001D4 powered by a Soundstream PCX2000D amp ? Ported box around 34 hertz ? Any Good ?

Btw if i get the holes in the firewall the wont be visible right , because theres a gray cover on it so u dont see the metal ?

2000 watt RMS is enough right ? The Alternator is 120 amp and i have a new battery , and i will be upgrading to 0 Gauge wiring ...

How much cash on the box though ?

I suppose the Pionners are OK, but come on man, you have a BMW, people are gonna laugh at your Pioneer subs. I would puit something nicer if I had Beemer. 2000 watts is definitely enough to dim your lights severely, so make sure get the install right. Box can be custom made for around $200 I guess, or get a used one. Genarally bigger the box, bigger the bass, of course it is trickier than this if you pay attention to detail.

So by class u mean , expensive or something like MTX 9500 or RE MT's ? right ?

i would go for RE mtx is to popular with everyday consumer
