hey guys. i know a buddy of mine whos got an RE SXX on an SAE-1200d 220a OEM series dc power alt 2 out of 3 big 3 optima yellowtop and 0ga to the amp and hes having issues with his sub cutting out randomly. the amp isnt going into protection and when it cuts out its only momentarily. i noticed he was only running one set of 12ga from the amp to the sub and told him he should step that up. my only other thoughts would be a ground problem but im not sure what else it could be. any advice would be appreciated.

Don't really see a security section, but I just had a quick question regarding Directed units that feaure the dual stage impact sensor that is an internal part of the main unit. I used to mount external impact sensors to the steering column shaft. I always seemed to have good results with the sensitivity there. Anyway, the new units that are all integeral, state in the install manual "since the shock sensor does not work well when mounted firmly to metal, we recommend against screwing down the control module" So how and where is the best place to mount to control module? I just installed one top of the line 2 way unit earlier with zip ties to part of the metal dash brac…

I figured this was the place to ask, since I cant seem to find anything after searching Google. I want to be able to plug in my USB drive to my Pioneer's IP-BUS interface and control my music from the HU, but Im not sure how to do it. I know the CD-UB100 does this exact thing, but I cant find any used ones for sale (I should have bought one a while ago when I found it new for $35 ), so I'm wondering if there is a way to DIY on making a USB input through the IP-BUS connector? I have found pinouts of this connector, but the onle pins they list are grounds and left and right audio. This would only be good for a 3.5mm stereo cable, which is what I have now. Im wondering…

I just installed a HID kit today that i recieved for my bday... instalation was alright. It came with set of bulbs, set of ballasts, and some small 1x1.5" black cube with power and ground and stuff... but my right bulb flickers alot.. and sometimes just dosnt turn on. And the left sometimes dosnt go on. But i believe i need a relay switch.. not sure where to get that.... if any other questions to help me fix this please ask!

I have an Alpine SWR-1022D and a SWR-1023D Dual 2ohm woofers. I just checked each woofer. If I wire the two coils in series, I get about 5.6 - 5.8ohm. Parallel is 1.7ohm. Both speakers are very close to being the same coil resistance. I'm just wondering how my Dual 2 ohm coils are so far off from the resistance that they should be. Why such a higher resistance?

i need some advice on how to build a buss bar for my setup. my batteries are side by side and that is the only way i can mount them. i need the bars to stay as close to the batteries as possible (cant go by box). my battery rack is adjustable so normally they sit below the back seats and for shows i can raise them up.

Hi Guys, Hope you are all well and i aslo hope that some one can assist me with working out the correct spec for a true SPL box. please note I will only be doing SPL with this box. Ok so I have 18mm ply wood, 1 12inch subwoofer, 1 amplifier and 1 battery. Here's what i'd like to do Get a minimum of 151db's from this setup Equipment DD Z1a NSB 170 12v Targa TG301-DW The sub specs are as follows and i could be wrong because this is taken directly from the site. 12" COMP SUBWOOFER - DUAL 1 SPECIFICATIONS Fs (free air resonance): 48.7 Hz SPL (efficiency, 1W/1M): 89 dB Nominal Inpedance: 1/2 Ω Qts (total speaker…

Ok so this is the first time I'm amping some mids/highs in my car using a 4 channel amplifier. I have 2 infinity reference 6x9s by an SSL F400. I bought one of those cheap amp hookup kits from walmart just to fill in the gap for wiring I didnt have. (8gauge power and rcas) I got really bad engine noise at first through the 6x9s. I troubleshoot and made a new ground for the headunit to the chastity of the car, also made a new ground for the amp to go to the same ground my battery in the trunk is grounded to. (strut ground) the engine noise was reduced but is still present. everything sounds good, but there is still some audible distortion. I have a pair of stinger bass blo…

So just recently my subwoofer and Amplifier started cutting out. What I mean is the speaker will play for a few seconds at the normal loud volume I play it at regularly then the sub starts making a weird noise, the amp light dims, and the speaker basically just stops playing. Any ideas what it could be? Maybe a short behind the speaker wiring? Just wanted to see If I could make this troubleshooting faster cause it's a pain getting that speaker out behind the seats of my single cab truck. I have a Sundown SA-10 wired @ 2 ohms Diablo Audio Technology 1000.1 About 1.25 Cu. Ft. Box tuned to 34 hz

Since the website changed I am not able to add the Manditory pic from Photobuck. I am able to add pics through out the post using the "IMG" way. Is there any way to use this method in the Mandatory pic?

I am going to install a sub/amp in a 2000 Accord EX this weekend. Has the factory CD player in it. Does anyone know if that will have a power turn on/powered antenna output to switch the amp on/off? I don't want to wire a switch or run it off ignition... Also, no PAC TRUNK-LOC or anything like that in the build, amp has high level inputs, and that is all it will get... Any help would be appreciated guys... -Mike

I recently have taken out my Fi Q and put in another sub to test/listen to before sale. During the uninstallation of my Q I fussed with my amp / tightened conections/took rcas out but not power or ground wire/ lifted it off the amp rack exc. Upon reinstalltion of my Fi sub when volume gets high, the sub seems to be skipping out on hitting its notes/ skips. I was thinking off the bat that it was my rcas gone bad, as it has happened before. Another side of me thinks that its my electrical, maybe one of my batteries is dead and is only kept charged by the rear battery. I have a horrible but operating set up -to regular starting battery 4 gauge to battery in back which i…

I've had a buch of bass installs , never payed much attention EQíng the front stage because the bass was simply to loud to notice the flaws the frontstage had Now I want to attempt to get a frontstage that is more than decent , no SQ comps , just for my enjoyment I want have it really good . A good part of a system is EQing the system to get the staging tonal balance just right , but with what music or reference tracks best to do that with ? reason I'm asking is because I keep turning on knobs cause I can't find "it" what I'm looking for with the music I'm familiar with .. there must be some stuff that can get you close in "steps" followed in a logical order

Hello all, as the title says I have some USB problems. What I mean is I had put songs on 2 separate drives and only a small portion actually play through my HU. I tried searching through the drive from my HU and pick a song that wasn't playing and it won't play. But when I plug the USB into my computer or Xbox it shows and plays every single song. I have also tried putting songs on in sections and every single song works, but when I put all the sections together it doesn't play them all. My friends usb's play all the songs no problems. So maybe my computer is a POS and won't put them all on? Idk, does anyone have any tips or advice?

First off what is already done: 130amp alternator Yellow top optima 55ah Big 3 1.5 digi cap (bought this a while back before I knew very much about car audio) SAZ-1500D JL 13w7 (for sale if anybody wants it) Planning on two SA-12's when the JL sells My question is, I have an XS power D975 (2100amps max, 35ah) on the way, now should I just scrap the cap and just go with the power cell, or should I go ahead and just add the power cell to my setup? I have searched all over the web and every car audio forum I can think of, as well as YouTube, to try and find an info on how to wire a second battery with a capacitor as well. It's all either one or the other, can't seem to find …

Ok, so I'm very curious on learning about electronics, and repairing/diagnosing. First, I want to get opinions on where do I need to start. I've read a pretty good bit of info so far, but seem I've limited to what I can learn without doing it. As I'm a more hands on type, only way I can learn and understand is if I do it. And or if I'm confused about something, having somebody connect the dots I'm missing, then it clicks and I understand. So far I haven't found much on actually repairing car audio amps, most is just electronics in general. Which I guess is the same, just seems I get over my head easy because I don't know the basics yet. Basically I'm looking for pointers…

I've been looking around most of the forums and the only replies are "I wouldn't do it", but the question is never answered. Is it as simple as strapping two similar amps per coil or is there more to it. Also, can you put more than two amps per coil. If so, how. Thanks

I went out to my car today to run the big 3 and realized that the hot wire that runs from my alt to the battery is a plug not a regular wire like most cars... How do I run that now? The car is a 94 dodge stealth r/t
