Noticed one of my 40 amp fuses on my 1500d is fuzzy looking on the left inside part of it. I'm not trying to damage anything, so I'm wondering what's the proper way to remove a fuse without causing anything else to break? Thanks, Nick

Gain matching two sub amps... as easy as eyeballing it, right? If not.. details?

So far I'm loving the new system but I've noticed with some songs (the loudest) and also at idle my voltage can drop down to 12v. It always jumps back up to 13.8+ volts after the bass hits... Should I be concerned? I still need to upgrade a ground under the hood, hoping that will help a bit.

No higher end, high output alternator manufacturers make a alt to fit my car even trying to retrofit isn't possible. I do have a 220 from powerbastards that utilizes a stock casing and after a month my battery light started coming on. But I think I have some good news. After taking it to a specialist It does 220 like PB says but the voltage regulator went bad but everything else is working fine and he'll replace the regulator and says there shouldn't be a problem anymore in fact the build (constuction) of the alt was good even the ratio of windings (voltage) vs diameter (current/amps) was ideal. The one issue with the regulator was amp draw between the rotor and what the …

hey guys. quick opinion thread. I already have my big 3 done and 1 run of power from back to front with 1/0. I have a DC HO alt on its way 200 at idle. i have 2X XS D3100 now and an optima red top onder the hood i will be replacing soon. my new setup will consist of 2X Sundown 2500D witch i already have. my sub stage is a supprise only some of you know lol. My question is... do you guys think with me upgreading all my wire to Welding wire is actually nessessary? my plan is to change my big3 with all 4/0 wire. and have 2 runs of 3/0 power front to back. i am not worried about the $200+ i am spending on the supplies i need including the wire. I am just cerious to see what …

Ok guys i'm wondering what could be causing my problem with my amplifier. First of all I'm running an saz-1500d with a fi btl d2 ohm at 1 ohm. Electrical wise is an optima up front, stock wet cell in back, everything done in 1/0 ga including big 3. I've had this installed for at least three months now with not a single issue with the amp. And It was working perfectly fine earlier on my way to work. Then going home from work I had it on for about 5 minutes, cop was coming so I shut the amp off thru the headunit(pioneer), cop passed turned it back on played for about 3 minutes then the amp just shut off. It won't turn on whatsoever. I checked my amp at home with the car run…

So If I have the ZED Leviathan amp and the AudioControl DQL-8, and they both have crossovers. 1. Which would you use, the crossover in the ZED amp or the crossover in the AC DQL-8's? 2. Why? BTW the Leviathan and EQL-8 are going into two(2) sets of Bravox Audio CS60K components and one(1) SSA DCON 12D4. Please don't recommend anything other than the two crossovers available in the two units mentioned. TIA!

Hey guys. So I am going to be running 2 Crunch GP3000D's here in the near future and I am wondering what the benefit of strapping the amps vs. running one amp to a pair of subs? My subs are/will be dual 1 ohm coils so I can wire each sub to 2ohm and let the amp take it to a 1 ohm final load or I can strap the amps and wire all the subs to 2ohm final load. IMO, It would be easier to wire the subs to 2ohm and then run wire from 2 subs in to one amp and repeat for the other subs and amp. Since I have never strapped amps, I am curious what the benefit would be and would it be worth the extra work to try and multiple wires to the sub terminals.

hello, first post. i am hopefully getting a Fi BTL soon . anyways, i am either gettin one 12" or one 15" probly a 15". they are 2000RMS. i can get either dual 2 or 1 ohm voic coils.(ohms is the main thing i dont get in car audio) now, which should i go with? dual 1 or 2 ohm? 2 ohm is more reliable right? also, if i wer to go with dual 2 ohm...when looking for a amp, i would be looking for a amp with 2000 rms at 2ohm right? or would it be 4ohm at that point? (2ohm + 2ohm?) and for the dual 1ohm i would be looking for 2000rms at 2ohm? AHH... so confused. plz help me with this. any opinions on amps is GREAT! i dont want to spend 1500$ on a amp. i need kinda a budget amp…

Those amps put out rated right? was Looking into the tarantula series and D-tower

So i'm sure many of you have heard this question before but i cant seem to find a good answer.. I'm running an Fi bl 15, on a sundown sae 1200d in my scion tc. Big 3 is done. Stock battery is some kind of panasonic. It seems that its not regenerating power quick enough or something. I will start my car in the morning and be at like 13.8 volts, and start it up a few hours later and be at like 13.4 upon startup. I want to be at a consistent higher number than this. Also how can i prevent my voltage from dropping so low when at loud volumes, getting tired of seeing it drop in the mid 11's and having to worry about it. I was going to get an optima yellow top but dont really …

hey guys..im about to order some 1/0 to do the big 3 in, and was wondering if it was worth the extra money to buy welding cable, or if knu 1/0 would do the same thing. Im only asking because i've heard some people say bad things about knu because its not pure copper. Also..do you think 15 feet would be enough..its on a 01 cavalier. Thanks!

which amp would be best for my 2 15 inch mtx 9500's. they are d4 coils so im gonna wire them at 1 ohm

My lights don't dim or anything, maybe slightly if i crank it up. but its an 05 Civic, stock alt and battery...is there still any concerns i should be aware of? my amps: JLA 400/4 (using 75x2 currently) class a/b MTX 1501d (using about 1400 watts, 1.33ohm load) class d 4 guage power. Overall, system seems fine, nothing cutting out..etc. The OEM alt is a Mitsubishi, no idea how many amps it pushes but i'd be suprised if its over 100a. if lights don't dim, is it ok?

I'm trying to help find my friend a us amps xt-2000. I'm looking specifically for the older models which had 90 amps of fusing and did rated power. They used to be for sale on ebay for around $120 but now the only site i can find it for sale on is woofersetc and it's like over 300 bucks. So if you guys could find any legit sites with this amp for sale please let me know. Thanks

I need a 5/6 channel amp for one of my cars. I need about 75-150 or so watts per channel on channels 1-4, and a 5th (or 5th and 6th bridged) channel to run a sub with 500-1000 watts. I was looking at the following: US Amps AX-5600 US Amps USA-5600x (getting hard to find) Hifonics Zeus ZXi60.4 + 1k Memphis Belle 16-MCH1300 The only problem with the latter two is that they are most likely made in China... which is a huge turn off for me given my recent experience with chinese made amps. Anyone have any other suggestions? Sub is unimportant at the moment, as it will be picked after the amp is. I'm trying to stay under $500, if possible, but that is not a hard cap. I alos wan…

Hey all.Im going to be getting an AQ2200 amp soon and I was told I need to get another battery.I kinda figured I would need another battery but Im worried my alternator wont be able to keep up.As it is right now my head lights and other lights dimm when I have my music up with a autotek 1500 watt amp.My car is a 1977 Oldsmoblie Delta 88.The alternator is a remanufactured one and I have no clue how many amps it is putting out.I know the alternator isn't that old.So my question is if I put another battery and a AQ2200 amp in will the alternator handle it or will I need another one or what?I haven't done the big 3 yet as im not enterly sure of what it consists of but I know …

Alrighty! So after installing a cd player in my girlfriend's car some of the dash lights dont turn on. The door open, brights, blinker, etc. (square lights for some warning or another) all work, but not the lights that light up the speedo, tach, or temp. gauge. I had the - terminal disconnected while doing all this wiring, BUT i may have effed up when i tied two wires into one. Reason for doing that was the wiring diagram i was looking at said that they both were for illumination, so i figured they both needed to be plugged in to the CD player's illumination light. Would this have caused hell for my wiring? I've checked the fuses and changed the only one that was blown,…

I am looking to get a new head unit. I wanted to ask the experts first. Is this one any good? 4 volt preamps. 6 channel preamp outputs. etc. http://outlet.crutchfield.com/p_613KDCX494/Kenwood-Excelon-KDC-X494.html?ssi=0&tp=13566&tab=features_and_specs

So I am trying to figure out which LOC is best. I know about the 3SIXTY, CleanSweep, and new MS-8. I'm not really looking for anything that complicated. I want to retain my factory steering wheel functions, sat. radio, bluetooth func. etc. I really believe in the modo, K.I.S.S.=Keep It Simple Stupid. Because of this I was dead set on the Audio Control LC6iBUT just found out about the re-Q5. Now I'm unsure which is best, and more importantly best for me. 1st the re-Q5 is just a bit more than the LC6i but still with-in my budget. The fact that it is said to even out the bass output at all volume levels seems like it could be usefull if the factory h/u tunes the bas freq. do…

im having a little problem with my amp. right now i have a sundown saz-2000d hooked up to two 18" dc xl's at .5 ohms until i can afford a better amp and get more batteries to support the extra power. but so far the amp is doing alright except at times the amp will go into protect only when i turn it up. it doesnt happen all the time and whenever it happens its random, meaning it sometimes will go into protect the moment the bass hits when turned up or sometimes after a whole song has played through full tilt. right now my electrical is a 250 amp alt with the big 3 done in 1/0 gauge wire and an xs power d3400 under the hood with a d3100d in the back all with 1/0 gauge wire…

I did an install way back, maybe 15 years ago on an 88 Nissan p/u. New speaker wire all around, two amps, amp board behind seat, tho whole enchilada. The 1st time i ever attempted such a thing. My p/u had a fiberglass shell that attached to the cab via a rubber boot. There was a carpet kit in the bed of the truck which held my sealed box with two 10" JL subs powered by an old school Rockford amp (Punch DSM). I had Pioneers for speakers powered by another Rockford 4 way. A set of 6.5's in the doors, and a set of 6x9's in the back installed into the carpet kits cubbys that it had. I also use an external 6 channel MTX crossover. I was in college. It was definitely a budget b…

well we built a wall, the amp is currently fairly far away form the subs, about 6 feet of speaker wire goes to each sub, we are currently using cheap 14 gauge speaker wire LOL, but we are pulling a 152.7@1800 watts clamped, my guess is we would gain quite a bit by changing out speaker wire, what would you guys recomend? there are 4 dd 1500 series 12" subs hooked up to a planet audio 3000 wired to half ohm in a wall. looking for the best speaker wire that will transfer the power most effectivly for the long 6 ft run. thanks, Anton Miller

What gauge size are the power supply connectors for the sax-1200d? thanks

I have been playing around with my kenwood deck lately and want to make use of its USB direct control thing. I like the idea of getting the numerous CD cases out of my car and being able to control it all off of my deck. the only problem is, whenever I play music off of the USB, it looses sound quality... (volume drops and the bottom end sounds weak). Why would the same song sound great from a CD but sound bad from a USB? Is it suppose to be this way? Also, would the 3.5mm aux imput sound just as bad? I really want to figure out how to get rid of all of the CDs in my car so any advise would be appreciated. By the way, the deck is a kenwood KDC-MP538U Thanks Alex
