Hey crazy, my birthday is today too. But hey happy birthday man.

Unfortunately my headunit doesn't have any subwoofer control because it only has one pre out. It just has a EQ for treble, mid and bass.

Yea it's the DEH-1200MP. I really wouldn't want to turn the bass level up on the HU though. Wouldn't that cause clipping to occur much easier ? I mean it'll make it louder and help with the gain but in the end might hurt more with clipping.

Well yea I'm dumb. It was wired down to 1 ohm. I must've been half asleep when I wired it a couple weeks ago. So it ran fine at 1 ohm on a single channel even though it still isn't stable at 1 ohm even on a single channel. The amp doesn't get hot now. Only thing I still don't understand is the gain. My head unit goes to 64 max volume and with the gain almost 3/4 way up it's not even very loud until I have the volume at about 58. I don't really feel comfortable having the volume that high but I also don't want to turn the gain up higher. I can turn the gain to max though and the sub never gets warm. It stays cool to the touch even after 30 minutes of abuse. Could this be because the pre amp out on my HU have a low voltage ? My HU only has one pre out and it goes into my highs/mids amp first then from the out on that amp into my sub amp.

I'll have to tomorrow just to make sure. But last time I had it wired to 1 ohm the bridged connection wouldn't even power the sub at all. It just wouldn't accept the ohm load. Thanks for the help. Much appreciated.

I realize everything you said about gain... I know it's not a volume control. I have read all the stickies and such about setting the gain. I wasn't to afraid having it all the way up when it was getting such little power because I figured it wouldn't get enough power even if clipping to burn it up... I don't have a DMM on hand to use to set the gain right now. I'm going to get one to set it but for now it is what it is. If the gain wasn't all the way up there was honestly no bass. I wasn't just trying to have it incredibly loud. It was seriously quiet if not turned up. My amp does have bassboost but I have it set to 0. My HU has bassboost also but it's off there too. I also have the bass set to 0 on the equalizer. But there's an update on my situation. I went to drive somewhere and just got back. I was driving for about 50 minutes back and forth total. Had the HU at 50 and was listening to music just about the entire time. Around 40 minutes or so my amp shut off again and I thought I had blown the fuses again. I turned down the volume and kept driving but it eventually turned back on. So I'm thinking oh it must have gone into protect and it turns out it did. I get home and feel the amp. It is incredibly pucking hot. Like burnt my hand feeling it hot. Obviously over heated. I don't understand why it's getting so hot. I'm going to turn the gain down and test how hot it gets tomorrow. It's never overheated before but I guess giving my sub 4 times the power it was is making a lot more heat. NOW I'm afraid the sub is clipping or going to clip and destroy itself a lot easier.

I have a 18" Fi SSD d2 running off of a Powerbass ASA 400.2. The sub is wired at 4 ohms right now and was actually only running on one channel of the amp and getting 100 watts. I just changed it to bridged because I just now realized it supports 4 ohms. It's rated at 400 watts when bridged. My gain when only running it on one channel had to be almost all the way up for the sub. Is this because it was only getting 100 watts ? I still wouldn't think it would have to be turned up so high. I was really worried about clipping but never had any burning smells when playing full blast for extended periods of time. The amp gets kinda hot but never overheats. When it is wired bridged I only need the gain a tad less than half way, maybe half way at the most. It still gets slightly hot but it doesn't seem as hot as before. So I changed it today and was trying to set the gain by ear for now. I had it around half way up and it was fine at a decently loud volume level. I turned my HU up from 48 to 52 and not even 2 seconds after being at 52 the sub just stopped. I checked the fuses and both of the 15A fuses were blown. I tried turning the gain down very slightly and was playing at the HU at 54 volume, even higher, to test and see if they would pop again. Everything was fine for about 20 minutes until I changed songs and they popped again after 15 seconds or so. Is it because the gain is set to high ? The sub is only seeing half of the power it wants, if that as I'm not sure what the amp truly puts out. My lights dim slightly when idling and playing it at max volume. If I'm driving there's practically zero dimming. I also have another amp hooked up for my mids and highs, a Hifonics HFi100.2 but it's not blowing any fuses.

Awesome box man, your craftmenship is outstanding. It looks damn loud.

Just buy a home theater receiver if you're going to be running a good sub for your computer setup. I have a 5.1 Yamaha hooked up to my computer along with Yamaha floor standing towers as my fronts and a pair of Technics floor standing towers as my subs, both have 2 12" drivers each. The technics are actually powered by a seperate plate amp I took out of a different sub. They're only seeing about 125w but they get plenty loud. I'm going to be purchasing a single DCON 12" soon for some more output and lower extension as they are obviously tuned to home theater specs and don't sound like I really want them to. It'll be in a single ported box tuned to 33hz.

Ah ok, thanks for the info.

When are these items going to be back in stock ? All sizes of both series are out of stock.

Awesome build man, keep it coming. They do look very similar.

Ahh ok thanks for the clarification.

I'm not seeing anything in the store for the sale.

My email was dated for today at 8:26 PM EST. Never have I had a problem receiving emails.

Not going to lie, it's pretty shitty to send an email About the deal 2 and a half hours after it ended.

I'll check it out, thanks Any suggestions on the calculator then ?

I'm looking at building a new box for my SSD. 9 cubic feet is a bit much in my jeep Pretty straightforward question. Only thing i really know of to design a box is the RE calculator. Whats the best though ?

I had it working without the antenna plugged in before, but I'll try it with it.

I checked the fuse for the radio and it was good. It would help if i had a power supply..

Well, I might have. Would explain why the damn thing won't turn on. Anyone way to tell if its fried by looking inside?

Nope, didn't even bother since i was just changing the remote wire.

I was re wiring some amps back up in my jeep today and everything was working fine, including the headunit. I took it out to change the remote wire and put it back in, only to find out it won't turn on at all, completely blank display. I have a Pioneer DEH-1200mp, relatively new. No blown fuses, not under the dash, not on the back of the headunit, nor under the hood. I didn't smell any burnt smell from the headunit.... I really don't see how it could have fried either. Strangely enough, if the remote wire is connected, both of my amps power on without the ignition turning on. so I have to keep it disconnected otherwise the battery will drain. I tried connecting the ignition wire to the yellow 12v, but the headunit still won't turn on. I'm at a complete loss as to why. I know the power wire is working, otherwise the remote wire wouldn't turn on the amps. I don't understand why its sending a signal on contact though ? Shouldn't be doing that unless the ignition is on....

That sounds promising then. Thanks.

Oh that sounds promising then. I'm not as worried about the displacement because the car is like half the size.
