It will house 2 RF P212d4's. Not the new black models the older ones with the removable magnet cover. I would be able to design one but I do not have the manual and rockford's website does not either. It is going in a Scion TC so I am going to build it to specs which is 1.75 cubes per sub. Tuning anywhere from 35-40hz. I will be powering them with a Diamond D3 400.1. Height cannot be more than 12", W cannot be more than 40", and D cannot be more than 16". Someone please design me a good ported box for these woofers to these specs. Thanks.

My Current system is this: Headunit: Clarion DXZ785USB Amp: Old School LA 1000D Subs: 2x Alpine Type R 12" Components: All stock, but they keep up. Tweets in the a frame, and 5 1/4" in the front with two 5 1/4" in the back. Forgot to add i have a 200amp alt. to power this. ANd all the 1/0 guage wire to run a big three. All of this is in a restored 1993 Range Rover Classic LWB The Box Design: Credits to Fallen at Roe. He designed this 6th order bandpass.

well as some of you may know i had alpine type R components, but from the flex of the back deck, it broke my cross overs, im going to leave the rear fill empty but i would like to find a pair of cross overs to keep with these speakers... incase i wanna sell them.. or i buy another lincoln i have a set ready, my question is, what should i be looking for while shopping? i see all kinds... but no type R's..... so i ask does it matter?

So, I've been pondering this a while now... Why is it that the majority of home theater or home stereo drivers are designed for higher nominal resistance? Would the main reason to use 16 or 8ohm loads vs. 4ohm loads be to keep THD ratings down at the amplifier? If so, is this primarily just a result ipso facto of engineer marketing? THD ratings of 0.00000000001 into a 16ohm load sell's $1800 home amplifiers.

So I just moved my XCON into the garage yesterday because I was planning on putting them both in tomorrow. This morning while half asleep I bumped my toolbox and a heavy ratchet fell directly onto the dust cap..... After getting the dust cap off I was surprised to see this. So I'm assuming this means that I can still put them both in tomorrow, and just put the cap on when it arrives? (Thanks to Aaron for taking care of me super fast!)

What kind of music hits what hz? I listen to rap and some areas to me are real low. I get confused because I read and people say that rap is all in the 40-50hz range. And then I see that people tune their boxes to maybe 27-29. Is there a program out there that like plays music, then shows you where the hz level is at?

does anybody know of some good Components, budgets around 300 are so this is for my work van they will be powerd by a SAX-100.2 .thanks

My drive to work everyday is a little over an hr, and i listen to this album every morning I could listen to this everyday and die a happy man lol Which one is your current favorite CD?

Ok I was at the shop today and decided to do my FIRST hands on experience in box building. I took the old face of my box and decided to switch it out to a dual btl box. Of course I messed up a little bit. What I messed up on was the shops saw went out today on me and I decided to use a jigsaw to cut the bottom of the face (major "f" up) . So my face was a little uneven. So I plan on using bondo and resin to fix it. With the face put on the box spray painted black it is hardly noticeable, but tomorrow will test my first challenge. I will also be bracing the mess out of the box. What port should I use? I am thinking 2 or 3 aero (pvc) ports, but what size aero (pvc) ports a…

I put some in the hatch area of my car (97 Subaru Impreza Outback Sport) today and down in the spare wheel area but that's about as far as I got because I was getting too hot and hungry. I'll work on the rear doors and back seat area next week, then work my way forward from there. After I got cleaned up I drove down the road for some ice cream and maybe it's just the CD I put in (the new Big & Rich) but the subs kind of sounded... softer? But I also think they were a little cleaner sounding. Is that normal? Is that one of the properties of sound dampening? I guess I was expecting an opposite result, thinking it would focus more of the sound towards me. I prima…

I have a deh-p590 ib with 4v preouts which are actually 2.2-2.3v. My gain was originally around 1/3rd on my sub amp set with a dmm at 3/4 volume with a 50hz 0db test tone. I hit the power cable on my amp and fried it. I replaced the amp with the same one and had to turn the gain to 2/3rds (around .75v mark on the amp) to get the same output voltage. I figured i screwed up my head unit, but didnt really think twice about it. Last fall i bought a pdx 4.100 and four new speakers... with the gain all the way up i could not get the correct output voltage using a test tone and dmm. I turned the sla to +4 and the gain settled around 3/4 up (just past .5v mark on amp). I just put…

In my searches for raw drivers I came across Renaudio. Everything looks good on paper so I was considering looking into giving them a try. Has anyone ever used their drivers before? Any thoughts or opinions on their quality, sound, or customer service?

Have A O-scope or something to help me set my gains correctly? got a new amp and need some help

I have a 2014 Honda accord sedan that is in dire need of a serious audio upgrade. The issue i'm having is I can't seem to figure out how to upgrade the electrical to support the 3-4.5k watts I plan on running. The Alt only puts out 110A but the shops in my local area say its a "ballsy move" to upgrade it because the engine is only a 4 cylinder 2.0. Would getting a VCM and a step down module be my next option to support the amount of watts I plan on running? any advice helps! TY

Not sure if this is the correct place to post...if not, mods, feel free to move! I recently installed a HU for a friend. She has a 1989 Ford Taurus. When she bought the car, the front speakers didn't work. I replaced the speakers last spring, and that did not fix the problem. This past weekend, I installed a Pioneer HU, hoping that would correct the issue. But, no, it did not. So I am wondering...could I just splice new speaker wire into the Pioneer side of the harness, and basically run new wires to the speakers? In doing this, I would bypass the factory wiring, hopefully solving the problem. But, if I bypass the factory wiring, won't I also bypass factory gro…

Hi guys, I'm new at this. Not really sure how to post. But here goes. I am planning to to connect up 2 amps. A 300w mono amp to 10inch Sub & a 4ch 640w(max out put) to 2 front splits and 2 rear speakers. I am gonna run a 4 gauge from battery to a distribution block and then run 2x 8 guage to the amps. am i using the right gauges? i was also thinking of running a 1 farad cap from the distribution block aswell. My plan is 3x 8guage from distribution block. 2 to the amps and 1 to the cap, is this the right way to wire it up?Also my friend told me that it is not necessary to pre charge the cap. Is this true? Coz i have read some forums and they say to charge it prior to …
