Well I once again thought an update was in order. A few interesting developments. Recently won an amplifier naming contest for **Zed Audio**. I named the new 6 channel amplifier 'LEVIATHAN' This contest awards me $100USD towards a Zed Audio Amplifier, and another 'free amplifier of Stephen's choice (from other manufacturing at the Zed Audio factory). I don't know what the free amp will be, but I trust Stephen will make it intersting. The $100 credit towards a 'Zed Audio Amp' Will go towards my purchase of the Leviathan when they are built. The Leviathan is still in the design stage now. Recently I got a great deal on an **OmniFi System** that comes with the car and home units aswell as the wireless antenna. Should be a lot of fun playing with that. This should be an easy way to add a lot of functionality to either an RFX-8240 or RFX-8250 using the auxillary RCA inputs.

Man, what a nap I had! So, how has everybody been? I have some boxes in my garage that have been around for awhile. Might revisit and use a few things. It’s nice to be back! TheHammer

I have a 4 channel amp (Alpine PDX 4.150) I have a component set with passive crossovers. I have a dual 4 ohm 8" sub. Channel 1 on the Left Front Channel 2 on the Right Front Channel 3 on one of the 2 4 ohm voice coils on the sub Channel 4 on the other 4ohm voice coil I thought the amp would bridge down to 2 ohms but it does not so can I power each of the 4ohm voice coils off one channel of the amp? Thoughts? The Hammer

I've never done this in the past. Usually bridge the 2 channels to the proper ohm load. Mistakenly thought this amp was flexible. Hope it's not noisy on the components. The Hammer

Need a new deck: Pioneer DEH-80PRS? Alpine CDE-137/138BT Clarion CZ702 Kenwood X996 Must haves: Bluetooth streaming USB input at least 1 for iPhone control Good visibility (for convertible) Considering going active so good processing might be a plus. On the fence about Sat Radio Any opinions? Please be specific. Ask questions too, I'll provide what info I can. Thanks, TheHammer

OK, I bought an Audio Control LCQ-1 off eBay, that should solve the bass roll-of issue. Still think the stealthbox is a bit pricey. Anyone heard one? Specifically for the F-350? The Hammer

I have an F350 that has captains chairs with center consoles front and rear. The stock head unit is quit acceptable feature wise, and even the door speakers are not awful, the lower frequencies are quite lacking however. I thought a nice clean way to solve the lack of bass might be to put a JL Audio Stealthbox in the center console (preferably the rear one) I don't even know where I can get one (I'm in Kamloops BC Canada). Another option is a "custom made" box with another sub in the center console, or a "truck box" behind the seats ( ick :-/ ). Any opinions? Know how I can get the Stealthbox at a reasonably price? I do have a 10" Cadence Beast subwoofer here not in use. Another problem I think is the stock deck "adjusts" (lowers) the voltage output to the sub as the volume increases. Anymore issues? FYI, I have access to: - Alpine PDX-M12 amp with bass knob - Audio Control Epicenter (1st generation) - Carver KLW Audio Phantom (bass enhancer) - Audio Control EQX - Audio Control MVC Thanks, The Hammer

try this TheHammer

Thanks guys, some replys lacking detail, but still a cross section. Fast, good MP3/USB reading makes a difference. Wish Crutchfield Canada would get their act together. They advised me to order from Crutchfield USA and ship to a USA address, then have that person forward it to me in Canada. I really like the fact that they throw in the install kit. but don't have any Amerifriends. TheHammer

Thanks, seems no one dislikes the Pioneer (most expensive one). I am disheartened with Alpines last few years too. The Clarion and Kenwood are still on the table tho. The Hammer

Upon further research it seems that Audio Controls new Accubass feature is designed to overcome this bass roll off. Featured on 2 of their current devices. The LCQ-1 and the LC2i.

After installation and calibration of the clean sweep I would end up with the same problem (if I desired to use the factory volume knob or steering wheel controls). Bass boost at low volume, and bass attenuation at high volume. (according to this video anyhow). I guess it might not be as big a deal as I imagine it could be, but wish there was a work around short of changing out the factory head unit. And I would require 2 units, both the main CL441 DSP and the CL SSI. Damn, The Hammer

Sounds like voodoo.

I'm not sure a cleansweep will solve the problem if the stock head unit equalizes bass out of the signal as the volume is increased. As I mentioned I'm not exactly sure what is going on. Isn't the MVC similar to a cleansweep? The Hammer

Well I sent an email to the head of international sales for JL Audio, and he sent an email to the head of the Canadian distributor for JL Audio, and he sent an email to the closest authorized JL Audio dealer, who sent an email to me. All of them offering to help me get a Stealthbox. So fine I can get that underway now, but still need to overcome the bass output lowering as I increase the volume of the stock head unit. Does anyone know these stock ford unit very well? Thanks, The Hammer

MVC PDF manual I am just assuming that the stock Head Unit has front and read high level outs (amplifier built into head unit). I know there is an stock sub and amp behinf the rear seats (that definitely under perform and have very little adjustment ability from the stock head unit). The Hammer

With Ford it will be several frequencies, so the only way it would work is if he could adjust Q as well. Worth a shot versus spending the extra dough on a processor though. Good idea! Again, I'm not sure what outputs the deck has for certain I assume high level front, high level rear, and weird adjusted sub channel. I thought of a few solutions or work arounds. 1- If I only used the front speaker outputs, assuming those are full range, run those info my Audio Control MVC then that can make 3 sets of out puts out of the single front output of the deck (so I would loose fading and some adjustment via the stock Head Units controls). I could set the levels with the MVC, and amp gains. run my own 4 channel amp to power the fronts and rear speakers. Use my Alpine PDX-M12 to power the JL Audio Stealthbox. Have I flawed in someway in my thinking. I guess I would have to use the knob for the MVC to adjust volume too? If I used the stock HU volume that might work too? or maybe not. The Decks out puts are the key to solving this I think. The other thing I thought is to just use the sub output from the stock head unit and compensate n the fly with the epicenter or remote knob for the sub amp. Really need some experienced advice here, I'm sure loosing volume control from the steering wheel controls or the stock units controls will not be desirable. The Hammer

As I am in Canada I emailed the Canadian distributor (and have been ignored so far) I would like to keep the stock look as I like it (Harley Davidson Edition), so the Stealthbox suites me just fine. Not sure what I would need to stop the voltage adjusting as I turn up the volume knob. Any suggestions? not sure what outputs the stock head unit has. The Hammer

Tried twice, apparently they don't care about selling me one of these. I guess I'll have to phone The Hammer

Wow, did I doze off again? The Hammer

Alas the Leviathan was never put into production. I never claimed my prize for winning the contest. Stephen (Zed Audio) is close to making another line of Zed amps however. A 6 channel (6 x 150w) is in the lineup from what I understand (not sure of the name however). :clap: The Hammer

Really?? How long was I out? The Hammer

I fell asleep for a bit. What's been going on?? What time is it??? The Hammer

What your describing is the reason I prefer seal enclosures myself. I think you notice a similar reaction with most drivers. The Hammer
