oh sorry i didn't see this. i can power it up out in my car no problem.. what did you have in mind?

bump for requested pics

it's a 100 amp fuse, and i haven't checked yet, but i don't believe it popped. like i said only 2 of the 3 30 amp fuses popped and the last one was fine. i opened it up and took some pictures on my phone. they aren't great but i whipped out my camera and for some reason it wont focus at alllllll. so this was my only other option. here they are, i took a picture the whole thing. then i took a picture of each quarter of it, kinda for a close up here i noticed some like brown sticky [glue?] stuff.. not sure what it is but i don't think it's a big deal, but i thought i'd take a picture just in case.. it's kind of hard to see, but it's just below the wire. i put the original (unpopped) fuse back in for comparison, but those are the fuses i was using all new ones though.. all 30 amps. the color is a little off, both are green but i don't think that really matters does it?

why?!

good morninn i'm excited, i got my new laptop yesterday. it's so perttyyy. now i just gotta fix my damn car/amp/sub.

i havent done any electrical upgrades yet, including the big 3. i was planning on doing it this weekend (before any of these issues came up) and then once it came up i knew i had to do it now. my only problem is my alt is under my AC and basically teh whole engine, which means i need a lift. and i won't be able to get a lift untill at the school auto shop on tuesday. ill see if i can get into a family friends shop today. my only problem is, i can't find my engine block to chassis ground. and i don't know if this is normal or not, but my only ground coming from my battery is going straight to my engine block. is that normal? and should i upgrade that too?

more more more!! i wonna see the interior. thats a sweeeeeeeet car though. great find.

yea i know im gonna get a new alt asap anyways. and i'll open it up today and take a picture for you duran. what kind of things should i look for as far as burnt? would it just be black? or broken (like on a fuse)? fyi i haven't smelled any burning at all. or seen smoke. the only thing i could think of was that there was some loud pops and what not when my alt wasn't putting out enough power for my sub. (back before i turned my car off and found out my battery was completely dead). and my head unit kept powering off as soon as the bass would hit because it couldnt keep up. and in the process of that there was some fairly loud pops, but nothing too weird. nmssd12 - i didn't think of that ill check the fuse on my powerwire. i would think that if that fuse was broken, then there would be no complete circuit going to the amp anyways? so that couldn't be the problem could it?

crapppp so i got new fuses, hooked it up. did a load test to set the gains and everything up again. (i lowered them when i noticed it wasn'tw orking right. about where i would normally get my max RMS @ 31.6v i'm getting no more then 15v. is that an amp or a sub problem?! i checked my sub out, it looks fine on the exterior, then again i don't exactly what to look for. and when the sub is playin above about 12v it sounds like it's clipping. but once again i don't know what that sounds like from a sub, but it does definitally sound different. ideas??!

welcome to the best forum around.

k, thanks. no, i have no idea waht happened, i got it somewhat snug tight with my hands. buy it was still freaking out, when i hit the brakes (just light enough so the light will come on) my battery meter on my dash dropped down to about 7, sometimes less, volts. and when i used my turn signals it would drop to about 11v everytime the light was on, and go back to 14 when it was off. then when i got home my brand new battery was completely dead. so i tighted them down, jumped it, and it was fine.. (kinda) since. before the old battery died i started having weird issues too, like what i described earlier with the lights, except not as much of a drop, and it would take for ever to recharge. like if i was to turn on my heater fan, it would drop to about 11 volts and stay at 11, like my alt wasn't keeping up. i'm sure i need a new alternator anyways. it has 196,000 miles, original alt in a 91 pathfinder haha. thanks for your help. i'll go put the fuses in now and give it a shot.

43 pages in less then 11 hours. must be a good day at the hop. i was gonna catch up, but not 43 pages worth.. hello fellow hoppers!

so i was tunin my amp for my 12" Q. and i wanted to use as little bass boost as normal on the amp. but even if i maxed out the gains, set my LPF around 80hz, and turned down my bass boost to 0db. i was only puttin out about 17 volts (if i remember correctly i did it early this morning). i know it was below 20.. and i needed about 31.6 volts. is this normal? i used 50hz tone when i had no BB, and when i used it, i used a 60hz tone. the only way i was able to reach my needed volts, was when my gains are just over 3/4 set, and my bass boost is about the same spot, 15-17db. but is that about normal? would it be better if i maxed out the bass boost and compensated with my gains untill i had the needed volts? fyi i'm using a 1.5 sealed box, stock electrical. gonna upgrade big 3 and possibly battery this week/weekend if needed. thanks in advance, and thanks for the amazing sub! it sounds great i just wonna make sure this is somewhat normal. this is my first system and i don't wonna blow my first sub, or anything for that matter.

okay i didn't think of that, i will try at a higher volume. the reason why i did it at 40 is because my mids start to clip at about 45+. i'll turn the gain down on that amp and try from there. i noticed that, but i wasn't sure exactly what it is/does. or how to explain it to somebody on here, so i haven't tried. but since i think you know what i'm gonna be talking about, theres 2 settings on there in the "SW Settings" i think it's a LPF but it gives me some options between 45-125hz i can choose from, i set it to 80hz, and the second part to it allows me to pick a number between -26 and +6. i thought that was kind've like a bass boost, so i left it at 0. i'm not sure how to set the crossovers on the HU, i can't really find a noticeble difference between any of the settings, for the highs, mids, or lows on there. and theres a second setting maybe you can help me out with. after i pick the frequency if gives me the option of picking "Q1N, Q2N, Q1W, or Q2W" i have it set to Q2W for all "High, Mids, and Lows" because it's louder. (i set my gains with this set fyi)

i am using an amp, except it's under my passenger seat and is a pain to access. but if thats what you guys think i need to do i can give it a shot.. i haven't any idea how i should tune those amps though. should i just turn the gains down adn leave the rest? (i didn't even put the amp or mids/tweets in, they came with the car. idk what kind any of it is except the amp is some sort of U.S. Amp. as far as 40/62, when i had the DMM connected, i played with the volume, it increases the voltage ever 2 volume levels. ex) 40/41 volts are at 31.6 42/43 volts are at 35.2 44/45 volts are at 38.4 i didn't go higher then that due to my highs clipping (using 60hz test tone). i can't seem to get them to get off the low's no matter what i set my HPF too.

the guide said to do this without the subs connected. but i checked the voltage with the subs connected, and at 31.6 without subs, it dropped to 28.7 volts with the load. i didn't mess with gains or bass boost when it was connected cause wasn't/aren't sure whether that would damage them or not.

deadening really helps that much? my only problem is i'm kinda cheap, considering i'm a student and all. and this is just a temp car untill the snow melts and a good deal comes around on a nicer car. this one has 198,000 miles on it, i'm not sure how much longer it will last. how much do you think it would cost for a whole small suv's worth of deadening? enough to block out most of the noise?

would i check the voltage the same way i would tune my amp with my DMM? but pioneer says my preout is 2volts. and john helped me out on another thread, if i took what he said correctly, then i would use the following formula for my situation. SAE 1000D 12" Q 2ohm DVC 1 ohm load (he said to use the "Final Load" this is it right?) 1.5 cuft sealed enclosure Voltage = sqrt(1000W X 1 ohms) Voltage = sqrt*1000 Voltage = 31.623 is that right? what i did when i was setting my amp was: 1) put HU on 40 [max volume 62, i like 40 personally] 2) set up the deck eq how i prefer it [no experience, just noob ear] 3) set LPF on amp to 80hz or so. 4) (my sub is not connected at all during this fyi) then i turned the gains up slowly, i believe i got around 17volts when gains got maxed out. 5) cut back on gain about 1/4 of a turn and started turning the bass boost up untill i got the suggested volts.. should i max my gains, and turn bass boost off completely? what do i need to change here. thanks everyone.

i would much rather not use a DMM and use and oscilloscope, but i can't afford one, nor find one in town without making someone go out of their way for me. which is what i do not want at all.

Opinions not based on some facts or experience should not be shared. by opinions i was referring mainly to personal experiences more then just plain thoughts. you gotta start somewhere after all. Somehow I feel like you are wordsmithing to change your answer to fit my request. Either way the past is the past, just don't throw "opinions" around in the future. hehe, i suppose i kind of was. though i didn't really think of it as just opinions. i'm not that dumb i usually give advice based on personal taste/experience. i guess my views aren't all that accurate anyways, so your right i wont just toss them around like i suppose i was.

how is the training? my old company fell through and i'm looking. i considered subway but i didn't know anyone who worked there before. Wasn't any really...... it is easy. sweet. my options are either subway, or a couple different local tourist shops that pay really well. not many places are hiring nowadays

well i know hahah, i'm not winning considering he has mod powers and i don't. and he is just all around smarter then me. but he keeps giving me crap about everything, and i really see no point in it. not to disrepect you M5, or anyone on here. i wasn't tryin to start an online fight, just sharing a story about my day and everyone started talkin about how chitty of a person i was for 5 minutes of fun. now can we end this already. please. it's getting rather annoying.

k. i'm not trying to give bad advice, i'm just trying to give my own thoughts. sorry. i know when i ask questions, i'd like to see as many opinions as possible.
