Yes. Stepping up to that much power requires a fairly big electrical upgrade. Your battery(s) aren't going to supply enough power, you'll need a h/o alt to power your amp(s) and keep your batteries charged. Depending on if you want to play for long periods of time with the engine off, you'll need a battery bank... Not trying to sway your decision in going big, just want you to be aware that amps don't make power and the bigger they are, the more power they require. I'll be looking out for your build in the future

So I leave the current resistor on the new harness, and the new one will be connected to old harness?

If possible, I'd like to not cut open the plastic mold (that way when I go to sell my jeep I could put the stock alt back on). Couldn't I wire and solder the red wire from the new harness to the original B+ on the old harness and wire the white wire (ground) on new harness to the old harness ground? And then the new resistor your sending me would go on B1 and B2? Would that work? Am I right about the resistor going on B1 and B2? If not, what does it connect to then? Thank you for all the help, I appreciate it. -Stefan

Here's what I got so far after talking to Kyle, Do I need to unplug the resistor from the new harness and solder it to the old plug (labeled connector a)?

Here's the wiring from the stock harness:

where the stock harness connects into the rest of all the vehicles wiring, part of it is just wired together and wrapped with tape and plastic housing, and then theres a snap connector, but it doesn't look anything like the new harness. I'll get a picture of what I'm talking about

Your idea of sq is of: "beamer, mercedes, etc cars are fast" and true diehard sq audiophiles is of: "formula one cars are fast" Bad analogy, but my point is: The btl is geared for getting loud, but it still sounds good and in end you'd be happy with it's ability to accurately reproduce bass. Now if your #1 goal is true sq then you'd look into the Qs icons xcons... At least that's what I believe.

Titebond wood glue works well

videos!, have fun

if you can afford the electrical upgrades and amps to run ~4000watts then get a pair of btls, if not, go with the bls.

If this for your 18" Fi Q? Is this going in a car or home audio?

I believe you can accomplish all your goals with replacing factory speakers with better ones, rather then just adding more and more speakers. Quality > quantity.

that's some amazing work you do man. I like the skull girl praying

I always just tightly wrap electrical tape around mine

sweet, thanks for the update. Powder-coat or not, these alts are simply machined beauty.

well i would like to just have the bottom, side, top, back..MDF, then i would just like the front fiberglassed..with tilted subs port in the middle..my estimate would be about 3.5 cubes...Don't have packaging peanuts so I just have ballpark numbers or any other ideas.... Sounds like it's going to be 99% rectangular shaped, so volume measurement should be easy to attain

I'm not hating It just sounded like you just thought you could run a 14v battery on a 12v electrical charging system If mechman doesn't get back to you, talk to DC power and be sure to post videos when done, I'm a pic/vid whore.

DC's customer service has definitely improved for me ever since they joined the SSA forum. There a very busy company and sometimes takes them a while to answer emails, and catching them on the phone I've read is hit or miss. First time I called, Kyle answered and I ordered my alt in 5 minutes. Later when I received my invoice, I noticed my address was incorrect, I sent Kyle a PM on here and literally a minute later I had a response with a new invoice and address correction. So far in my CS experience I've been very happy! Once I receive my alt and it's installed I'll have a nice review on their product!

What type of fiberglass enclosure are you going to do? like design or look wise. Depending on shape you could still use basic geometry to get a pretty good estimate of volume. Or you could always try the packing peanut idea, it should be close enough.

I agree with frostedflakejake, song is like a 20second loop But it does sound good If I have time I'll make a video

Sounds like an old bass track from the 90s

If your going to run 16000watts then you should already know what your doing... You cant just run 12v and 14v batteries like that. You could use stepdowns so you could still charge 12v batteries on a 16v setup, but thats expensive. Run two alts, one for stock, other for stereo electrical. Let me ask this, Do you have a High Output Alt? or planning on getting one?

Yeah you can but the real question is that difference worth the $1800 price tag difference. Go to your local shops and listen to the low end hertz or morel and then compare to the high end products. Trust me you will notice a difference, it may be minor but some want that extra acoustical performance from there speakers over what average users use. But at the end of the day it will still come down to the install. Yeah. I recently installed some coaxial focal 6x9s and hertz 5 1/4s for my fathers truck, think we spent around ~500 and they sound so crisp and loud. And these were just coaxials nothing fancy
