Ok which amp is the best outta these few?

[forsellb 1]

Ok I was told the Sundown 4500D is a bad amp because the 86% eff @ 4ohms at 100Hz, so I was told to look into the HellFire 2500.1, the MTX TA92001, and the T1500-1bd. I am going to be getting 2 12" BTLs, fully loaded daily drivers. Anyone have any words of wisdom?

Also what about the Alpine MRP M2000?

Also Id be running the sub at 2 ohms most likely, depending on if I get one or two amps

I don't think the sundown is a bad choice they do rated power PLUS more, i own the saz 3000d and i love it.

Yea, I didnt think it was either, but all the amps I posted do rated power, then some. and the sundown has a 'supposedly horrible' eff ratio.. Im so confused now.. I was just gonna get the 4500D plus the BTLs but then my friend told me about that eff thing now Im lost lol

[Julian 641]

They're great, my amp barely gets warm running at 2 ohms pushing 1500+ watts rms on a fi bl 15

does it have great SQ? I mean I understand its a massive amp but yea.. So you think the original plan for the 4500D is still the best idea? And if I run it at 1O for 2 12 BTLs it should be fine?

[Julian 641]

Yeah, i think so, but i dont have my sub stage and front stage battling over who is louder, so its pretty goddamn loud but its pretty even and nice. I have not had the pleasure to play with the BTLS but the little brother the bl is pretty crazy sub, you could always do two Bl's on a SAZ-3000d buy it refurbished from www.db-r.com 555 before shipping b-stock. that's what i spent

[bassahaulic 155]

Who told you that? I want to know so I can slap them in the face for being retarded. 86% is fine. And who cares about the 4ohm efficiency I mean really? Going to be running it at 4ohm playing 100Hz only?

But you have to remember the 4500 is a large step up compared to all the other mentioned amps. And to meet the power output of the SAZ you would need two-three of the other amps.

Hell Fire 2500.1

Efficiency: 88.6% @ 4ohms

MTX TA92001

N/A

RockFord

86% @ 4-Ohm

85% @ 2-Ohm

68% @ 1-Ohm

Well they said 86% @ 4 ohms at 100Hz is bad, and showed me these.. I was surprised myself. Im planning on 2 BTLs so I was counting on 2 of the other amps listed, I want 2kw rms atleast on each. So the 4500D is perfect right? 2 ohms on the subs, 1ohm at the amp.

holy shit 555 total? and I would but I am addicted to louder, so its BTL all the way for me probably gonna cost around 3Gs for me

if you do get the Sundown make sure you have the electrical for it, batteries, big 3, H/0 alt etc

this is what the 4500 is pushing in terms of power

3100 Watts @ 1 ohm nominal rising to 2.67 ohms on 14.4v dropping to 13.6 volts

4650 Wats @ 0.25 ohm nominal rising to 0.71 ohms on 14.4v dropping to 11.6 volts

ok not gonna lie, thats kinda confusing to me and I was planning on a 2400 kinetic batt per amp, 220amp alt(220 output at 1800rpm), and big 3? big 3/0 gauge wire you mean?

IMO It seems like your not ready for a big system like your planning. Your going to need 2-4 2400 per amp depending on amp. And big 3 is upgrading your main grounds and power wires under hood.

[Julian 641]

Nope big 3 is from alternator + to battery Alternator - to chassis the chassis to - terminal on battery (I used 1/0 wire). if you don't plan on runnning your system with your car off you should go with the Deka batteries they're half the price and do 100 AH's per 9a31 batteries for 187 and shipping.

[bassahaulic 155]

The SAZ-3500D would be the best amp for you. The 4500 is more geared towards SPL applications as it likes extremely low ohm loads.

The alternators grounds/outputs and stuff right? Also my cars battery is in the trunk, so yea.. But I can handle it, Im just being mislead in so many ways lol

There is no harm in under powering subwoofers, and if its not enough buy another amplifier and link em'

I've learned you dont have to push the subs to their limits.

if I remember right, the 4500 was one of the last amps tested, so the battery was a bit drained. if you have a very solid electrical you could see a bit more, and if you ran it at a lower ohm load (not sure its recommended to) you'd see a ton more than that 4650 if the voltage didnt drop to 11.6 volts.

Of the amplifiers mentioned, the Sundown SAZ-3500D or Rockford are your best choices and best value.

[forsellb 1]

So just forget about the whole eff thing? with the 4ohm 100hz 86%? And I was thinking what if I get the 2000D, one for each sub, would that be fine?

also is the 3500D underrated? Should I expect around 4kw or 3500-3800kw?

[jonbearsmt 919]

did i miss the part about why were looking at a 2 ohm load?
