Default Trying to match an amp with subs

Alright guys I am either throwing in 2 12'' L7 in my tC or 2 12'' JL W7.
I get both extremely cheap, i own a car audio business so any of you fellow owners wanna hookup lemme know .

Im trying to find an amp that will power those sufficiently. Im trying to stay away from running 2 amps, I would rather not, but if needed alright.
Looking for name brand, not MTX. Somehwere aroung 1500 RMS and 3000 Watt max.
Both subs are Dual 4 i believe? Correct me if im wrong

Thanks for you help guys

SPL DK-3400 is a really good amp for the L7's. my friend has it with 3 CVX which have the same power as the L7's and the amp isn't even turn halfway cause then they'll blow but he has them at 2 OHM.

Eh yeah haha CVX are loud i have a pair right next to me. But anything else? Anything by kicker JL or rockford that would really push those? Moneys not that great of an issue, on the fact that I get almost everything dirt cheap.

Would 2 amps be recomended? Im not even sure where i would put them :/

haha

If i wanted to I could throw in 2 JL 1000/1 no problem, thats not my issue.

You guys, from experience have been playing different audio systems so see what sounds best, Im going off of what people are saying, and not some print on the side of the box.
For the most part on audio, yes I know my stuff. What im asking is, a good amp that you guys know from experience will push 2 12'' About 1500 RMS and about 3000 watt max, preferable a monoblock.

Im trying to stay away from 2 amps unless I had a custom box to place them with, but I dont have my tC yet, so im getting ideas on this new car.

Now you wanna help me? Thanks

i still say the SPL DK-3400 watt amp
4 ohms: 1400 watts x 1 chan.
2 ohms: 2100 watts x 1 chan.
1 ohm: 2600 watts x 1 chan.
Peak Power Output 3400 watts x 1 channel
that's what you need for the L7 and W7 and a 5 farad Cap.

Just curious, why are you looking at 2 12w7's? The setup I am running in my xB is 2 8w7's, and it borders on overly loud. I had a single 8w7 that was decent, but once I added the second I had to cut the amp gain to half and turn off any bass boost or subwoofer gain from the head unit or my teeth would chatter and my vision would blur on the bass notes. I'm thinking of entering SPL competition with it, we'll see how it goes, just trying to say that 2 12e7's is probably overkill. Also, box space on the 12's isn't exactly small (1.375 sealed each, 1.75 each ported) not sure where you're going to fit them in the tC and still have a back seat. Ported for the w7's sounds better in my opinion, I have tried both with the 8.

My personal reccommendation if you want the symmetry of two subs is to get a set of 8 or 10w7, powered by a 500/1 for the 8's or a 1000/1 for the 10's. Of course, if you can live with a single sub, go big with the 13w7 on a 1000/1. Good luck. I'm not a JL fanboy, but comparing the specs, the JL seems to be the only one with a REGULATED power supply and load balancing to supply the same power output with a variable load from 1.5-4 ohms (this is impedance, not resistance, don't get them mixed up). Their EQ setting are quite nice as well, being able to set the bandwidth center frequency and width (Q).

Final note, the 13 is the only one with dual coils @ 1.5 Ohms each. All the smaller ones use a single 3 Ohm coil and can be wired in parallel on a JL amp while still being stable.

Rockford < JL IMHO, less features, less quality and similar price (yes, JL is still overpriced retail, and their no internet sales policy sucks, I buy eBay with a warranty through the seller, make sure they state it, some sell without one and you are SOL if it comes in damaged. Can't speak for Kicker or Alpine, you may want to try a smaller manufacturer like Memphis, Soundstream or Image Dynamics for amps.

Go for a T40001bd amp for a 4000watt rms amp! Or if you can find a T30001bd amp that will do 3000watt rms but the t4 replaced the t3.

Make sure you can supply at least 200amps worth of power for those suckers...

Anyways.
Yes i understand whats your trying to say I really am considering that, Ive just always had 2 12''s so those are usually my first priority in choice, I was going to go with CVR, but im just trying to find a good setup that im not going to have to switch around, im looking for a 1 hitter quitter system.

For those who dont bother to read and understand, yes I own a car audio business, my knowledge as far as matching Amps to subs is expanding. Im sure everyone has room for improvement in their job weather they have done it for years or months correct?

Back to the actual topic of this thread, Im just looking for a good sys that I wont have to rewire over and over. I have any set of subs and amp really cheap. I dont need to worry about a warranty, everything is covered.
Thanks to everyone who is trying to help me.

Lanzar Opti2000D produces ~1,600w @1ohm, ~1,950w at 0.5 ohm. Class D Amp 80% efficient 180A fused internally by 6 30As.

Price with 3yr warranty direct from their recommended reseller- under $450.

Opti is Lanzar's ONLY reliable amp line out there.
And just a little FYI to prove they are beasts, the Opti4000D, the 4,000w Class D amp, it uses the same board as SoundStream's XXX-6500D amp.

Oh, and Lanzar now has an Opti6000D. Those babies aren't cheap either.

You can also look into Sundown Audio if you are planning a little comp comp.

Those lanzar's are also strappable too.

Hifonics amps. Any amp that has some model like BXD, those are not good rated amps. The Colossus and the XXV lines are top notch.

Zapco if you're rich.
Kicker makes very nice amps as well.
