I had an old Thunderbird I bought as a kid, every morning after I bought it I went to start it up for work but it was dead. I was a kid, no money to fix it, no skills on figuring out what was wrong or how to fix it. I got a new bettery thinkin it was OK. Next day i was late for work. Checked alternator, solenoid. Copuld not figure the thing out. One day I had to disconnect the power seat for something, problem went away. For a few weeks now when I have gone to start the van, it seemed like it was low on juice. I have 3 AGM bateries, 2 of them huge 100aH. It's been on my mind, but was always hard to tell for sure if there was an issue. Today i went to bring Brandy to wo…

Hey I notice Ppl using 2 2/0 for There ground Could you explain to me why so much for the ground and where you would put yours at on your ground because I was planning on using 4 gauge on Body (A) > Head (B) > Coil Pack © > Battery Negative (D) > Body (E) And was going to use 0 gauge for battery negative - body But why would you use so big wire on the ground? I was told the car for the ground needs some sort or resistance for the computer to know, but 2/0 is bigger then 0 gauge. If i decided to do 0 gauge will I be ok you think Here is a site that does my old car grounding its similar to the same identical to my new car for what I am about to do. http://www.s…

guys i need your help. i have a sundown sax-1200d powering 2 sa-12s. lately the amp has been making this high pitch noise as soon as i turn my car on, and after 20 minutes of playing it will go into protect mode and it gets pretty hot. is the amp screwed up or is it something else? any help would be greatly appreciated, thanks

Ok so I have a 2005 mazda 3. After putting in a saz-1000D and a JL 300/2 (just ordered my sax100.4 which will replace the JL), my electrical couldn't handle it. So I decided to do the big 3 as it is the cheapest route. Well I just finished. And I think there was an improvement but not like I thought it would be. Now when my bass hits my voltage drops from 14.4 to 13.8 sometimes 12.8. This is with the car on and idling. And my lights still dim but not that bad as it used to. My car has a 90 amp alt. Upgraded to big 3 now. So my next step is getting a kinetik or XS battery for the rear to see if this makes an improvement. After I do the battery in the rear I plan on doing…

Hey all, I just picked up a Pioneer Premiere DEH-P880PRS off ebay for $200. Pretty good deal. The only thing is, is that it doesn't come with a cage, book, or harness. I get get the pdf of the book off of pioneers website. Does the 880 use a 16pin harness like all of the ones on ebay? There is a cage, harness, and trim panel on ebay for $15.00 shipped. So any help would be appreciated! -Ryan

My 2005 civic has only a 70 amp alternator and I was wondering If I can run a 500 watt amp without problem? Will my lights dim at night? This will be the only amp running and I would do the big 3

I'm thinking of getting this to push rl-i 8"s in the wifes car. I had a directed 1500D, but it's on it's way out. It states that it'll do 1500@1ohm, but how true to rated power does this amp do? Thx for any & all help. P.S. Here is a link to info on this amp. http://www.savinglots.com/lotprod.asp?item=XT4000D

Hi. Don't know if there was a thread already, looked back but couldn't find one. I need help. Alright. So, not too long ago, a friend that seems like he knows a decent amount about car audio set the gain and bass boost on my amp. My amp is a 1000w mono block, and it was pushing a 15" spl sub rated at 1400rms. It sounded really good, but all of the sudden, it blew a single voice coil. Obviously, I was upset. I got a replacement for the sub, the same one, but I just don't want to blow it again. Can anyone help with tuning the amp by gain? And I've also heard to NEVER touch the bass boost. Is that true? Oh, and when setting the gain, should I have my head unit as high as I…

looking for a new amp that does atleast 1000 watts at 2ohms and would like it to be under 300 any ideas?

Hi I jus bought a 12" Fi SSD sub with the copper coils and i was wondering which of these amps do you think is better. A Clarion DPX1851 or An Alpine M850 Looking for better quality and better proformance, etc. Wattage doesnt matter cause they are both capable of pushing this sub

I bought an 230A alternator from Nations Starter and Alternator in Cape Girardeau, MO about a year ago for $450, my warrenty is expired and now its squeaking. I spoke to the guy at the store and he says that there is no way that alternator is squeaking he said that he was 1000% (yes 1000%) sure it had to be something else but not the alternator. He is stuck on his work being perfect. All I can say is that I would never ever buy anything from them again. Ok now that thats out of the way, should i take it to an alternator shop to get it fixed, or should i just get a new one. And if so where can i get a 200-250 Amp alternator for a reasonable price? Its for a 2000 Dodge Dako…

i think i want the visonik 4000, if i can still find it for like 400 or less... other than that idk.. what amp can i buy that at least gives me 2000 to each sub? or somehwere arround thier., for around 400$ all the nice amps are like 2000 x1.... but i want a 4000x1 or something around thier lol,

ok i think i got it. check out the diagram, and tell me if its right. i heard that alot of amps will output a low freq or pop for a second when you turn the amp on, and to use a cap on each channel to not allow that freq. to get to my tweeters. the nominal load of each channel after i wire it up will be 1.5 ohm. so according to WinSD or whatever it is, it say that a 68uF 100V cap (with the 1.5 ohm load) will not let any freq under 1000ish Hz pass through that cap. is that right? i also have the Coustic XM6 (just ordered) which is 18dB per octave, and then the HPF on my amp is 12dB per octave, does that make my overall slope for the tweets 30dB? plus does the cap still add…

Hi, I have juste received an aliante 12si and i'm trying to figure out what amp would cope with it. I don't want mono one but a 2channels... i have a ground zero 4125SQ for the front which is a Focal KRX3. But i'm trying to find other 4-6ch to compare them (Zapco DC, Zed, Mosconi, McIntosh,...) I'm just saying this because i'd like the "project" (not build yet) to stay aesthetic so i will probably stay in the same brand for he amps. Thanks for your help

hey guys, just a quick question? whats a good battery to get for under the hood? i will be doing the big 3 to my new car i have a 18" btl fully loaded comming and a saz-2000d and a sax-100.4 on the way i have 2 kenetik 800's ill be droping in the back so whats a good battery i should get for the hood i got about $250 Thanks guys

Nothing to special, I bought a cheap amp from a guy on **** and got it in the mail today, its actually a really nice amp its brand new never been used. VVME QA-D1500 I hear its pretty much the same as the Audiopipe ASPM-1500 not sure how true that is. but i figure i could use it one day so ill keep it around for something to play with.

AVH-P5200BT I can buy one today brand new for 450.00 I like it because of the 4v Pre Out, the 8 band EQ and watching music videos would be cool. I think it'd be a nice upgrade from my Alpine IDA-x305s that got stolen. Thoughts?

Friend asked me about the phase dial on his sundown 1500. I couldn't give him an answer. What exactly is it and what does it do?

I ordered an Fi Q15 with BP Power option. Would a Sundown Audio SAE-1000D be a good match for this sub?

I´m not so god at english too start with cause im from Sweden! =) i´ve just bouht a saz-3500d and i´m wondering if i can load it down too 0.5ohm? At the moment im using it on 4 Audiotop 15.4 15" subs,and i had an Sundown 3000d before and the difference in preassure was really big and with the saz3000d i played 150.00 with music. But i´vw also bougt 2 Sundown nightshade 12" 2 * 2 subs and my otehr question is there any chance that i can play more than 150 db with the 2 Nightshade on the 3500d amp?

Well, my friend installed a Rockford Type RF.4 4 channel amp into his car and after it was installed a popping noise would occur when he turned on his HU or when he turned his volume from 0 to 1. We must have regrounded that amp several times but the popping still occurs. We tried replacing the HU but to no avail, same problem occurs. I told him to try regrounding his HU but his HU was already grounded to a drilled, sanded spot. Right now, he is trying to shorten his ground wire. Now this only happened after he installed this amp. Before, I had let him borrow my trusty ol' Orion Xtreme 5004 and there were no probs with that amp so I'm assuming it has something to do with…
