I saw your thread on the 06 xb Mechamn alt install, but no pics show for me. I was wondering if you have a 220a or the 240A alt I see listed on their site? I dont see a 220 a option.

SD-3 -- help matching amp
bmxscion replied to pumin's topic in Sundown Audio - GREAT Amps/Subs! GREAT Customer Service!
Markous- just make sure you set the gains on your amp carefully. These SD-3's are easier to bottom out than the other beefier models. But when you get it set right they are really nice. Do you plan on doing a separate chamber sealed box or shared chamber sealed.....or something else? I know how good my single 12 sounds, and I bet two would be pretty nice. What is your frontstage consist of? I have a full active HAT 3-way front stage in mine. -

I have an SD-3 12" D4 in a sealed box just under 1 cu ft. The one I have was the prototype unit that has the machined outer spokes unlike the production models. I have it powered by a RF 501bd and processed with an MS-8. It is an awesome sub but I will be upgrading next year so I may sell this one. -
how is your HU grounded? i have mine straight from the harness to the metal bar under the dash. I do not use the ground side of the vehicle harness at all. I am also running a 501bd and I have 2 551X's in my setup and I have zero alt noise.

DD-1 first time user - this thing is boss

A tip for those who have a DD-1 or any other SMD tool that doesn't plan on using them for extended periods of time.....disconnect the battery when storing. Protect your investment. -
long term review 220A Scion xB Alternator

Do you have the AVBM on yours? If so adjust it when full hot and with a load and that may help at lower RPM's. -

What is your resting voltage on your battery? Maybe you need to put it on a slow charge for a few days to top it off. What kind of battery is it? Shoud be minimum 12.6 V. Mine will rest at 13.1 after keeping my battery maintainer on it. -

The stock alternator is much smaller than the Mechman and there is room to remove it without taking the bumper off. The Mechman has to be put in from the front next to the radiator. With the bracket that is on the Mechman you have 2 lower bolts and it is hard to get to the one without having access to the bottom. Plus you have to check the belt alignment and you need the bumper off so you can see down the belt properly. I do agree with the guy in the video about the bracket with the airbag sensor on it being in the way to get the lower bolt out, although I did not remove mine but it was a PITA. You can try it without taking it off and if you can't then just remove it if you need to. Another thing is if you decide you put a ground wire from the alternator case to the beam connected to the radiator support like I have, you will have to have the bumper off to reach it. Make sure to sand down the paint/primer on it first and leave enough slack in the ground wire to allow for engine movement or it will rip itself out over time. Yes this happened to me the first day I had it hooked up. The bumper is not hard to remove. It only takes like 10 minutes. If you don't have factory fogs it is even easier and a few less steps to do too. -

I decided to do some cleaning and updates the other day. I cleaned up my terminals, did a little polishing, nothing serious, and added a few small details and connected a run of 2AWG of power wire from alternator POS to battery POS. Here are some pics: Check out the .38 Special shell I used to cover the threads on my battery hold down rod. Added some shrink tubing on the POS inputs to the battery. From left to right we have 4 AWG from starter, 1/0, 2AWG from alternator. The 2AWG was there already and is actually ran through the factory wire harness where the stock wire used to be. It wasn't being used and I figured it was a good time to make use of it while I was in there and now I have 2 runs of both POS and NEG to my battery from the alternator. POS connections at the alternator. The template I made for the new upper bracket to allow for proper belt tensioning. -

1. Gates Micro-V. I don't have the part # right this minute, but it is not the stock belt part #. 2. Having a helper is always nice, but I have gotten good enough where I can rip the bumper off, and do everything by myself. You will need to remove the bumper to do this properly. So if you have never removed the bumper having a second person is nice especially if your paint is in flawless condition. I recommend putting some frog tape or something similar on the edges of the bumper and on the fender to prevent scratches when taking off and putting back on, where the bumper and fenders meet. 3. I actually took out the OEM wires, but you can use both. I replaced my OEM wires with 2AWG Knukonceptz wire and then added 1/0AWG to compliment that. 4. All the bolts and hardware used came with my alternator. I only used the factory hardware on the upper bracket. I have found that i need to make a longer upper bracket to get the proper belt tension, because after the new belt stretches I am now at the limit of the upper bracket and I still need it to be tighter. It squeals like a mofo at start up and is annoying. EDIT: Now that I look back at some other pics I have, I did use the factory bolt on the lower bracket also. The silver colored bolt you can see in the pic above came with the alternator, the other bolt at the other end of the bracket is the factory bolt.
