Is hifonics or SPL good by any chance.
Have heard about hifonics but never about SPL.

[Invinsible]

Both are equally good amps, have a great circuit design. I would say they are good VFM. Though I would lean more towards the Hifonics if I had choose one.

[karankapoor]

hifonics are good for what they come never heard anything goog about spl,why don't you go for another 14001 i think that will be the best buy.

@invisible can you please elaborate on the circuit design i did'nt get you on this,or you want to say the circuit board looks good when you see them.

[abhinav.gupta88]

Final check needs to be done on the 14001.
If i calculate it on a general basis .

Alpine goes to a max of 35 volume.
JBL gives 1200w rms at 4 ohms.
If i assume it increases linearly as volume increases it should give 1000w rms at 29.166 volume.

Now when i tested by sub at 4 ohms , the bass was ok till 30. ( the amp did not lower the bass or anything)

But as soon i increased it after that , the amp lowered the volume . ( maybe due to over ride)

So will talk to LBM and he will do a better check.

If it does its duty well , it will be the 14001 , else i will have to search for options.

Good ^^....u can also go for the spl one of my friends has it !! he said it gave out more power than specified..some ~50-100 more (RMS).

Well i bought Hifonics Brutus 1208 D

[abhinav.gupta88]

Review on that Ankit.
Whats the price?

[ankit_chd]

Well u need to wait for the reviews , got it yesterday only .
Bought it from US , costed me 179$ including bass remote . Infact i am looking for subs now , upgrading my system ;D . As far as quality , it seems good and very nicely built. Weighs around 7-8 kgs .

have a read it at these and it's priced great too

Having searched a little one thing is for sure SPL seems to be a good amp for it's price, plenty of raw power if that's what you looking for. Am sure with the kinda of power you looking for you won't regret with either of them.

Again If i considering powering it at 2 ohms , then its underpowered and for 4 ohms , i think it will be better if i get the 14001 checked at 4 ohm by LBM before making a decision.

If you feel that's under powered than have a look at this.

It would give you 2500RMS at 2ohms which I feel should be perfect. And logically thinking how often are you going to listen at 2500RMS?

And logically answering If you have a sports car which can do 250+ Km/hr how many times will you go to that speed ?

Please do not mind it we SPL lovers are like that only.

The LOWEST bass maker in North India has spoken. The windows have been shaken(literally) and everyone has been silenced :-) Waah lbm paaji!!

Firstly your question should really be how many time will you listen to 140db+

My answer would be exactly once. After that you'd be deaf.

However there are 2 reasons for having that capablity.

1. A system that can produce 140db+ cleanly will be do a very good job of 100 db as well as it will be working well withing it's limits.

2. in LBMs case; you see my dear Invisible, our friend LBM is a true believer of Newton's 3rd law of motion. By facing the cones of his subwoofers towards the rear of the car he is able to propel the car forwards just by turning on his stereo system. :-)

Obviously to do that speed i would have to catch the speed way and not the by lanes. I guess that's not the case with the SPL.
But, with all due respect if SPL Lovers are truly looking for SPL then I guess having 2500RMS also won't suffice, sooner or later. Your ears and brain signal would have been shattered after a period of time listening at that volume, and all one would have to do is get some more serious stuff and awaken them, for me SPL means get a couple of Digital Design Z series( or serious) subs and amps i.e. 4600RMS at 2 ohms and more.

DDZ - Class Amplifier

Digital Designs recently introduced our Z line of Woofers, Amps and Battery. These products are single purpose designs with the sole goal of being the best tool for the job. No compromises, no cutbacks and no wimps.

The Z1a makes incredible amounts of power from stock electrical systems; it was designed to make the most power from limited current supplies. The high efficiency comes from paying close attention to every stage through the amp circuit. Multiple power supplies, high speed controller chipsets, efficient power devices and precise thermal management were key to the Z1a design.

These attributes make the Z1a at home in world record spl cars or high powered subwoofer systems where 400 pounds of battery bank aren't possible. One Z1a amp can power several big-time subwoofers to stupid loud levels when called upon, or dazzle with rock solid control of complicated bass lines. Z1a's are limited production, high-end amplifiers for customers who want the best.

DDAudio Digital Designs Speakers Made in the USA

Now that's what I call serious SPL stuff. How serious are you having experienced them on my last trip to US, all I have to say they beat competition hands down. Am not surprised if LBM paaji gets couple of these soon
