Looking to do a hair trick. Need help with system

lol must have been a ****** install. the softparts in the fi sub are MUCH better quality than the opti. my buddy has one i built an enclosure for and it had no low end and the soft parts ****** ***.

Same install, same power. The Opti had very comparable low end, but the high end was on another level compared to the BTL. Your buddy must not know how to install.

Lies
I'll post a video of my install. I'm hitting a LEGAL 144 off 600 watts RMS. The low end is insane.

check out my ninja edit i just realized its a newer opti. still feel the btl is superior

lol must have been a shitty install. the softparts in the fi sub are MUCH better quality than the opti. my buddy has one i built an enclosure for and it had no low end and the soft parts sucked ass. although it wasnt this exact opti. it was older. the newer ones might be better

I'll post a video of mine tomorrow. Absolutely ripping my car apart.

i did the install myself. what kinda box was it in? and was it the same box

...Specific amps pair up good with specific subs? Oh yeah, you watched youtube videos so you know first hand.

It does not take any more power to push a 10" vs 18" of the same sub..

lol ummm yes it does. the 18 is bigger, therefore it requires more electrical power to move it.

yeah the mms on an 18 will be higher, unless it used a different cone, but its not like your gonna need a different amp to drive it cause if that...

Cone area in a well tuned enclosure move air... I suggest 2 18s of your choice, but ones that are efficient at 1500 watts each since you do not have the funds to explore any higher and i feel like any of these would be good choices, i like the abuse the DD's can take though

Subs:

DD 3518

AQ HDC18

Fi Bl 18

Amp:

DD m3

Sundown 3000d/3500d

AQ 3500

Electrical:

1 Batcap 2000 if stock alt is 140+

Powermaster d3100 if stock alt is 110-140

Well that was insightful!

what eles is there to say. alot of cone area tune low. i have seen hair tricks with 2 18s 2000rms. u 18inch fi bls tune low off of a audioque 2200d .

 

[cdimic25 10+ year member]

Yea the power has nothing really to do with the air if the drivers are moving at whats given, i wouldnt necessarily do 2000 watts but it can be done.

dang i got off for a day and 20 new comments haha. Ok so its looking like 2 FI BTL's will be too expensive but just wondering is a bandpass a good type of enclosure for the Fi BTLs?

Maybe try a couple of HDC3s on 2kw. should be much cheaper overall.

You're a toolbag. An 18" uses the exact same motor and coil as a 10" version. If you're so right, than show me a single sub line that switches RMS ratings due to cone size difference that uses the same coil/motor. Here's a hint, the Sundown 8" uses a smaller motor, and the Type-R 15 uses a bigger coil, so look elsewhere.

Kenwood excelon and soundstream both do.... So
