  1. browser keeps crashing so this will be done in sections. Let me start with saying this build was done in the sub 20 temperatures with occasional snow showers. I only had 3 days to complete build due to long work hours so it was kinda rushed! I came here looking for ideas on a new build to upgrade from my original 4 kicker comp cvr's and this is the results! 160 Ft" of 2/0 EB-Flex welding cable 2 XS D3100's Sky High fuse blocks Sky High 200 amp fuses Sky High 1/0 oversided copper lugs Sky High shrink tube 1 set of aluminum battery blocks
  2. First time actually posting a build log but this year, I guess I will. I have done This will be the 3rd build in this Tahoe and I'm designing a C pillar wall with my wife (who actually has a ton of creative input.) I wish I could post some pictures!! First I am going to log a tear down of my initial build. This weekend I will start the tear down .
  3. here is a build i did a few years back on my truck when i was a noob and didnt know about box building, now its time to build a correct band pass box designed by ramdesigns for (4) 15 FI Q or SP4 powered by my saz4500 or some RF 2500bdcp im still downloading pictures
  4. Just a quick video of White Clouds playing on the Sp4 12's Completely forgot to turn my phone sideways to make the video but owell, enjoy anyway!
  5. Hello bass addicts, my preview project was stopped, I'm working on a new one, it will simply be: 2 SP4 18" in a kind of 6th order wall 1 DC 9.0k connected @0.35 4 PC4000 batteries (4000A 5s discharge, 115Ah..) Pioneer 80prs headunit And for the doors well see later, maybe some APS spanish products (quality hard hitting showcar components) And the car, a VW Passat break born in 1985 Pictures are being uploaded, I'll post them later Hope you will enjoy the build !

    FI SP4 12

    i just sold my 2 AQ HDC3 12inch subs and im ready to upgrade just don't know what subwoofers to get to many options has to be 2k rms + im running 2 strapped aq 2200 at 0ne ohm my voltage drops to high 13s low 14s im guessing i have 5k rms available my box is gross internal volume is 5.15 cuft port is 8" diameter and 15" long 36.8Hz, 50.24 square inches of port area. i thought about team ifs or sp4 12s but it doesn't have to be fi. that's just what im most impressed with right now this is my log
  7. So apparently an 05 Chevy Malibu's stock suspension was not designed to handle the weight of a 7.9 Cube box + XS XP3000 + FI SP418 I now have a very low rear end. Any ideas an how I can fix this without going air ride? I have recently replaced the rear shock absorbers as well as some front suspension pieces. Thanks.

    4th order tuning?

    hey guys, im wondering how to determine the tuning of a sealed section of a 4th order. i know sealed boxes dont ecactly have a "tuning" but ive heard they have an Fs. so in a 4th order, how do you get one to play really low? like below 20hz. ive also heard its good to tune the ported section to the sealed sections Fs. ive had a good amount of experiance with 4th orders so im just seeing how much of this is true. im wanting to convert my current 6th order wall into a 4th order for 3-4 FI SP4 18s and want it to play down to 20hz or lower. is there a formula for determining the Fs (tuning) of a sealed section of a 4th order? thanks for any input!
  9. I recently burned up the tinsel leads on my fi sp4 15 I have never reconed a sub before, so i'm wondering if it would be worth it to order the recone kit from fi, and do it myself, or pay more for them to do it. Is it very difficult to recone it? Also, Would you recommend the fi recone, or another brand like psi?
  10. Hey all.... Well, its that time again.. We are gonna rebuild. Thank you for following the RF Acura TSX build. And, to those that helped. We thank you. We are going to try a suv platform this time. NEED ROOM.. lol. Anyway. Some know what is up, some know even more. Stay tuned, as some will move fairly fast, some wont....... Cheers from Kyle and Laura...... and again, those we know... we also luv ya.....
  11. Looking to put together a 2 15" trunk system and need to compile a list of subs to pick between. I am looking for around 2000 RMS handling, 3-4 K burps, and some good X-max (30mm ish+). It will be used for music, bass boxing, and SPL with the emphasis on being able to play below 40 Hz at high volumes for extended periods. Not looking for a sub vs thread, just wanting some suggestions that would fall into the group below that I have not yet though of. Price is not a major concern but I believe all the ones I have found so far are in the same range so lets stick with that. I would be interested in used ones if you have anything similar. Thanks!!

    box in back seat

    Ok, so i have an 18 fi sp4 woofer. it wont really fit in the trunk of my 2010 malibu so i put it in the back seat. ive heard that it wasnt really a good idea but i did it anyway . it sounds ok but i know it has a lot more in it. its running on an re xtx5000.1 1 shuriken bt-45 mechman 240 the box is 7.5 cubes tuned to 30 hz. sub is facing forward behind the passenger seat and the port is facing towards the roof behind the driver seat. im wondering if there is a different way to do this, and i do not want to wall it off. any ideas? maybe just ditch the 18 and go smaller?

    help choosing an amp

    I'm planning to purchase a Fi sp4 15 or a similar type subwoofer in the near future. I was wondering what your guys opinion is on getting a hifonics colossus 3200w amp or 2 mb quart onyx 1.2000d amps to power the one 15. I'm trying to stay around the $500 range for an amp purchase. Thanks.
  16. Today I've just received my 18" Fi SP4 subwoofer. Paid over $250 for shipping to get one here in Australia. Currently I'm running it from a 3000w Pro Audio amplifier on one channel due to the 2.8 Ohm Impedance. I'm hoping to get my DD M4a tomorrow so I can give it the power it wants. Just wondering anybody else in Australia imported Fi subwoofers into Australia? I believe I'm probably only person in Australia to have one here.
  17. In india you usually don't see such kind of installs very often. This country is yet to see some crazy and insane guys most of the guys have in their ride already. I just took a small step in bringing that culture to india. First of all the ride in which everything went in
  18. Anybody heard one or own one? Is it worth getting?
  19. Planning on getting a Fi SP4 some time soon and have just looked on the website and it would appear the price has increased about $70, anybody know anything about this?
