I am getting new subwoofers?

Question

I have a 1999 Jeep Grand Cherokee. Currently it has a Kenwood KDC-X395 HU. A 1500 watt BOSS Phantom amp pushing 2 12" Kicker CVR's. I also have all Infinity Kappa Perfect 6.5's and 6x9's and tweeters running off a 5 Channel MB Quart Q series amp. I am getting 2 18" Fi Btl's N3 and I was wondering what kind of amp should I use. I was looking into Hifonics Brutus or Rockford Fosgate T2500.1, MB Quart Q series 2500. The subs are 3000 watts rms apiece. That is 6000 watts Rms for my box. I want to push them at about 11000. I have also considered a Warhorse from Kicker. Please give amp suggestions, why you choose that amp and links to it. Also how big a capacitor I need with links. And last how many battery's and what type, also alternater and what type.

By the way my subs are currently wired at 2 ohms. I was going to get my Fi's at 2 ohms also. If you have any reasons or ideas about different ohm age i.e. ( better sound, or more SPL) then please throw that in also. Price is no object so let me know what you think.

The last thing I wanted to figure out what my current box was tuned to. And how to tune the box for my Fi's to about 35-32hz.

This is the box that I currently have. Thanks for any help.

Answer 1

Well, I don't have any experience with systems of that magnitude so I don't know what amps to get, or how many batteries you would need, what brand of alternator etc.



That much power at 2ohms is gonna be super expensive...I would look to getting that much power out of 1ohm. In terms of SQ there won't be much (if any) difference partially because there's not much difference between 1 or 2ohms and partially because with 2 super high-power 18" subs that small difference is going to be meaningless given the insane amount of SPL those subs will generate when properly powered.



For tuning frequency it depends on what you want. Me personally, I would tune as low as possible for maximum depth and SQ (I have an enclosure tuned to 26hz). BUT you will generally get more SPL out of a higher tuning frequency. I would go for 32hz if that is the minimum tuning frequency, since that will sound the best...but if you want max SPL you may want to go as high as 45hz (virtually no SQ with a tuning freq that high). For someone with a system comparable to the one you are creating, I would say 35hz would be the typical tuning frequency.



BTW I'm not sure why you posted a link to your Kicker enclosure...if you are thinking of simply enlarging the holes for the Fi's DON'T! You're gonna need a big as$ enclosure for those subs (probably somewhere around 8-10cuft) and it's gonna need to be super strong and well-built to withstand the internal pressure created by such powerful woofers (I would say 1" MDF would be about the minimum, with a double-baffle for the subs and lots of internal bracing). Plus you're gonna need a lot of room to build an adequate sized port within the enclosure.



Good Luck!

Answer 2

Is building this system your hobby?

When you say price is no object.

I would go to a reputable dealer and go insane!



I alway loved Rockford Fosgate.

Buy t2500.1



Basic rule of thumb is 1 farad per 1000w



You're spending so much on equipment.

Why won't you build a custom box to match your subs?

Answer 3

Kicker 10C124 Comp 12-Inch Subwoofer are amazing! They're lightweight, but sturdy and bring tons of power and handling. I've got them in a bigger box and on less wattage than my previous subs and they blow everything away. I would suggest these for anyone who likes their bass. Get Kicker and stick with them.
