SPL & SQ / Fabrication

i will have 2 or 3 amps in my truck to power my speakers. I want to remove them from under the rear seat and build some type of mounting device for them. i have an 8 cubic foot box for my SP4 - could i mount the amps on the side of this box or on some wood attached to this box OR would the vibrations be less than ideal for my amps?

In my progression to finish my build, some of my amps may require amp inserts for dual cables per input. Now, i have the tools here to make it, that's easy. The thing i do NOT like about these inserts is how they are secured in the amp.. just by the little set screw on the amp.. For holding a solid piece, i fear the insert can "turn" eventually and i don't like that. Instead, i thought about purchasing a Metric tap and die set to tap the power and ground inserts on the amps. There appears to be enough metal in there to do so easily. I do not know 100% what size tap i need but i got some micrometers here to find out but the question is this- If i tap the amp and die the i…

So basically I'm slowly piecing my system together and had an idea for an amp rack that is somewhat "expandable". It consists of a wooden base, with a wooden box attached to the end of it for the amps, batteries, etc to be placed into. I'm planning on having ventilation and having the rear of it open faced. It would have shelving for the amps.I'm thinking I could secure the wooden base to these strap hooks I have in the rear of my truck (2006 tahoe), have them protude through the bottom then either use a heavy duty strap or bolts through them. I'd rather not drill into the body anymore than I have in order to secure it. One of the reasons I'd like this design is for secur…

ok i am pending the idea of having an amp rack instead of a backseat ( it depends on the qoute i get) and since the amp's would be in the open i was thinking about totally enclosing it and having the top back pexiglass so since i think to think totally through i was looking at ventliation for it since has been hot out latley ( i live in florida) and i am wondering what others with amp racks have used to. first i was thinking 12v fans but then i thought that i would need a exit hole for the air to move out. then i started looking at Liquid Cooling for computers since computers are 12v. and that is all i could think of.

I am getting ready to build a nice simple sealed enclosure for my 12" Xcon. While im building this, I would like to go ahead and build an amp rack. I want something fairly simple. A false floor with the amps mounted down in the floor would look nice IMO but I need help as to how to start or what to do? this rack is for my 2000 Celica and the two amps are a Kicker 10ZX350.4 and a SAZ-1500. Pics or videos or just advice would be great!

alright so i think im going to be mounting my future amp to the back of a seat. is that bad? and also what material is good so the amp doesn't rattle around.

I am Trying to come up with some designs for a couple amp racks, however I'm lacking creative touch I have seen a few nice ones on this site but just wanted to see if people would post some pics of theirs to give some ideas/show theirs off. I will probably be using mdf to make mine but I would like to see some of all different materials. Thanks.

I had so e spare time on my hands so I figured I would relocate my switches and bass knob. Let me know what you guys think!!!! I'll get some pics of it installed tommorow!!!

Well, here we go, I've created this in an attempt to make a tool that can help take the guess work out of all the difficult to figure on a calculator values we constantly figure for box building. I think this is a decent tool and that it could work for alot of us. I'm putting it out here for all to try and give it some real world tests. Let me know if you guys find anything wrong with the sheet just let me know I'll do my best to fix it. So here ya go, we'll try this link out first just copy/paste: =http://www.mediafire.com/file/ugzuqj4mzjw/Box Calculator.xls=

I'm designing a new box and have a sort of kink in my design. I'm looking to do a baffle with a 30 degree angle in it. Now the issue with this that I do not know the clearance for the sub since it will be angled downwards. It is a 15" Havoc (standard basket), and I just wanted to know if anyone had any ideas about the clearance. I basically need to know how far above the bottom of the baffle the sub needs to be to clear the bottom piece. Thanks!

this is going to be my layout for a new box ports gonna be up top they will be coming through the decklid and the subs are gonna be firing towards the trunklid.what do yall think of this setup?

car- lexus gs300 music- hip hop and rap sub- audioque sdc2.5 12 amp- jl audio 500/1 max height- 14.25 port tuning- figured 38 max depth- 14.125 max length- 31.125 using .75 thick mdf i get roughly 2.75 cubix feet.. so i figured with sub displacment and port i would be at about 2.5 which is what audioque is the biggest i should run the box.. now with the port i put in 2 inches wide by 8 inches tall and i would need a port length of 7.51 inches.. now my question is does all that sound about right? should i have the port longer? when i did the port at 14.25 tall and 2 inches wide it said i needed a port length of 14.71.. basically just looking for some advice on what to do…

I did search 'box carpet',and you'd be amazed (sarcasm) how much those two words are used on this forum. lol, i went through about 15 pages and found some good info on where to get it,but i still have one question. A lot of people said they got their carpet from a hobby store,and i'm just curious what kind of carpet to look for when i get there. I could be wrong, but i don't see them having "sub enclosure carpet", so i really just need a name to call it... If i can't find it at a hobby store, i guess partsexpress.com is the next choice ($5.85/yd... much better than crutchfield's $30 for 3yds.)

Just brought home my second first place trophy in as many competitions. Little higher this time. 150.1 In modified 901-1600.

Ok whats the difference in one box tuned to 35hz with 2.5cuft and another box tuned to 35hz with 3cuft? also whats the best material to build a box out of?

I would like help with a design of a box for a Sundown Audio SA 12" sub woofer , that is 12" at the bottom, 8" at the top 17" tall and 30" long, with the sub woofer mounted on the slanted side. I would like it to be ported, and tuned to 32 HZ. Again, 3/4" MDF 12" bottom 8" top 17" tall 30" long Tuned to 32 HZ Sub-woofer mounted on slanted side Truck-box style.

Looking for some tips on the trunk set-up. I have an 18" BL in there currently that is upfiring as it is the only arrangement I could use and still get it in the trunk. I'm looking at switching to a 15" though and can change it around if you guys have tried anything that works well. Firing into seats, firing back, port arrangement. stuff like that that I was unable to with the 18". Looking to save some time before I start tuning!! maybe you guys have had some good tips for me to start with. Any other good trunk tips would be appreciated to. If I compete with this in my car, it'll be a first. I've typically only competed with hatchbacks

I'd like a box cabinet plan drawn up I don't know if I'm going with this design yet or not, but if I do I'd like to have a plan for it. I'm basically doing a homebrew version of this: http://www.omegaloudspeakers.com/ts33.htm Using these drivers: http://www.madisound.com/pdf/fostexcabs/fe126e_encl.pdf If it models well, I wouldn't mind going with a tower speaker instead of a bookshelf - although I don't know exactly how it would react. Thanks...

Hi everyone. I'm a new guy here on your forum. I'm going to need some help from any REAL GOOD box designers here. I just bought (waiting for it to be shipped to me) a 15" Kicker L5 and i'm going to power it with a Hifonics BXI1206D amp. I'm currently driving a '01 Expedition and i took out the 3rd row seat so i have A LOT of space to use here. I'd like to go with a vented box, something that will give me some pounding bass but clean. This is what i'll be using: JVC KD-AVX2 headunit (2) audiovox headrest monitors DLS 5 1/4 component speakers (front) DLS 5 1/4 speakers (rear) HIFONICS BXi1206D - for sub HIFONICS ZXI6406 - for front and rear speakers KICKER L5 15" DVC 4ohm …

Hard to explain. Currently i have the standard single fifteen ported to the back, sub and port rear facing. I have a 03 maxima, and would be interested in sealing this to the interior of the car and firing the sub forward, with the port firing up through the rear deck into the rear window. I did something similar in my last max but still had the sub firing up. I sat i a car with two orion hccas sealed to the rear seat and ported finging up through rear deck, and NEED THAT. Anyone up to the task?

Im tryin to see if anyone can custom fiberglass me some door panels, entire door panels for both of my doors of my car. I know some companies locally that do it but they charge extremely, i mean EXTREMELY large amounts of money for it. To give you an example, they charge $1,500 to do a 14cuft wall in my car.... i dont know why they told me that a while back but that's not what i wanted from them anyway because i know how expensive they are. I'm lookin to spend no more than $300 per door. Is that too low? I can't find anything for a Scion tC.

I've been playing with a port calculator and I find that 30 1/8"x3/4"(which just happens to be my wall thickness) holes will tune the box to a nice 30.5Hz. Now, is there any reason for NOT doing this??? Thought I might arrange them in the shape of an SSA logo for effect.

As title says, there's a few shops here but nothing I trust..... I want a box built and designed around my cars cabin gain... Not a box just built to specs

This is about the best fiberglass walkthrough I've found. My plan thus far is to cut out some holes in the door panels, make some MDF speaker rings, mount them to the door panels with little metal brackets, spread some fabric over it, and put a few layers of resiny fiberglass cloth over it. Sand and repeat, sand again. Am I missing anything?

I have 4 15's I need to fit in my Altima! Kinda a wierd lineup but I got screamin deals so oh well! I need some advice on how to run everything! I have 2 Phoenix Golds XS2500's and a PPI PC2150. Heres my subs 2 15 inch JL Audio W-6's and 1 15-inchPBX PowerBass XSDv.2 and 1 Power Acoustik 15-inch FUBAR 15W(1000w RMS ones) This is how I was gonna set it up but need help! I was gonna run an XS2500 bridged to 2Ohm to the PBX and FUBAR!(1 to each bridged) than run the PPI to the 2 JL's.... What do you think? I have a cap too a phoenix Gold XSC1o at 1.0 farad but I know I'll have to either get another alternator put in or a Optima Battery! Which should I do? I havent hooked it …
