28-80Hz Issue
Joe X replied to Qwiz's topic in Interior / Exterior / Paint - Detailing, washing, waxing,tricks of the trade!
Your box probably is hitting the car resonant frequency and may be oversized to show muddiness and showing a sharp drop at higher bass. It is interesting that you provide no box specs, you see it doesn't matter much that the enclosure sound normal in another car. Also don't see what is your system, models for the speakers, amps etc. You provide no pictures to document your tests, etc. Even if you have an acoustics problem, there should be a way to work around the issues even if that means try different components, etc. -

28-80Hz Issue

Turns out it's the acoustis. I have been in two Kias. Mine and another one. Both horrible. The person in charge of the interior acoustic properties is nonexistent to this vehicle producer. -

Awesome...thank you so much!!! The amp is coming today, I can't wait to get started on this. I have a work trip that just came up...so I will be out of pocket till next Wednesday Couple of questions: - Are the triangles 2.5" wide like the other design? - The double triangle in the center of the port...I assume the clearance there is 1/2 the port width, so 2"? Thanks again for putting this together, I really appreciate it!

08 acura rl custom box help needed.
Ricks08rl replied to Ricks08rl's topic in Subwoofers / Enclosures
Ok. 2 12's it is then. Yea I can make the box a little bit bigger. I just didn't wanna get to close to where I have the amp mounted. I can actually make it about 6 to 8 inches deeper but that will only leave me about a inch away from the face of the amp and I really don't wanna be that close to it. -
You can easily run kicker 12s which like 2.25-2.5 cubic feet each, You likely don't have 8 cubic feet net, most trunk cars don't have that much. There are some 15s that will run in lesser airspace. like DC Audio brand which will need 3 cubic feet each but very few 15 subs will run great below that. When you have space limitations you alternative is more power and subs that can handle the power to get loud in smaller boxes, there are subs that can handle many thousands of watts of power each.

08 acura rl custom box help needed.
Ricks08rl replied to Ricks08rl's topic in Subwoofers / Enclosures
Hi, ok I would be able to run 2 kicker 12's comp r or the q series then if I am understanding correctly? For the 15's I just don't have the proper air space? -

Those are specified to work in 3 to 5 cubic feet net INTERNAL each, say, we pick 4 cubes for each as kicker subs prefer larger boxes and you would need 8 net, you don't have that. You are calculating external volume, net internal volume is the airspace inside the box, the space occupied by the sub, the port and the wood doesn't count. You will only be able to properly fit 1 sub of those. but it would be louder to use 2 12s that would need 4 to 5 cubic feet net internal that you should have.

Hi everyone. New to this forum and know this is where I should be. So I have a 08 acura rl and have started to mock up my box. I need to know if it will work and what I might need to change for it to be proper. I want to run either 2 kicker comp q 15's or 2 kicker comp r 15's. Love to get down into the low 30's frequency range. I listen to mostly hip hop and rap with some r&b also. I currently have a jp95 running my interior speakers and plan to run the 5th channel at 1 ohm. Says it will do 1k rms. Have seen test where it does more but calling it 1k to be safe. This is what I have come up with so far. Plan to run a aero port thru the top rear on the left side as that is where my factory sub was before I removed it. Wanna run the port up into that location to get the most sound inside.

Mikefenzel92 replied to btrango's topic in Sundown Audio - GREAT Amps/Subs! GREAT Customer Service!
Can i change my d4 sundown sav2 to a d1 and be ok? -
The Subs came in yesterday...they look beefy to say the least. I picked up a sheet of 3/4 MDF this morning along with some wood glue and screws. The amp is enroute and scheduled to arrive on Thursday. I ran all my power wire over the weekend. I ran a 1/0 from the battery and split into dual 4ga. for the two amps. Last night I installed my 4 channel amp and replaced my factory front door speakers with a set of JBL Stadium Series 6"x8" component speakers, 862CF. Just need to get started on the box for the subs now. I can't wait to see how this sounds.

Iced started following White Noise/hiss in my new system
-
Hello all. Equipment: idatalink Maestro rr2/ w compatible vehicle harness Kenwood Excelon dmx809s Incriminator audio IX6.4 @ -3db Incriminator audio ix2.1 @ -10db DS18 pro zt6; x4 Sundown SA V2; x2 XSPower D3400 Wiring is entirely Knukonceptz OFC, 0 gauge power run/ground, big three w/ the addition of alt casing ground, 14 gauge wiring runs to door speakers, Krystal Kable RCAs Vehicle: 2021 VW Passat w/fender system (bypassed amp) As title states, I am getting a slightly tolerable white noise in my newish sound system. I say slightly tolerable because I cannot hear the hiss unless there is no music playing or my vehicle is at a standstill. The white noise persists whether the car is running/on, RCA unplugged from amp, gains turned to lowest settings on amplifier (makes no difference), running a temp ground from amp directly to the battery, disconnecting the speaker wires, swapping remote turn on leads, using muting plugs on all channels, and finally running temporary speaker wire to ensure the ones I ran weren’t picking up interference. I have tested a brand new Skar Audio SKv2 100.4AB, the hiss was still present but quieter I have no clue as to why. My next move is possibly putting the amp in a vehicle to see if the noise is present still. If I have missed anything, please so share. I'm not sure if I’m just expecting too much from electronics that make SOME noise, but I’d at least expect the amount of noise a proper stock system makes which is next to nothing IF any. Are aftermarket sound systems just inherent to slight hiss/noise or am I being too much of a perfectionist with this? Thanks!

Looks like on the box in the link above the 2.5" wide triangles account for 26.17 Cu. In. per corner for a 16.75" internal height. The one in the center of the ports is double that, so 52.34. Does the 52.34 take away from "Port Volume"? Thank you...that would be much appreciated. I will be running a Rockford T10001BDCP and with the speakers being the Rockford P3D4 12's, I plan on sending a 1 ohm load to the amp. Is it ok to run speaker wire from one sub to the other through the port along the back...or is better to put two speaker terminals in? My max build width is 45"...height and depth really don't matter. Thanks again...looking forward to what you come up with. I am excited to get started. The subs are arriving today and I will try to sneak off work early enough to get a sheet of 3/4 MDF today or tomorrow. I will be posting pics along the way!
