Toyota tundra with stock alt, hid lights, 100rms x 2 channel on the doors and 1300rms on the sub. I'm looking into buying a new battery for under the hood because there is no place to install a second battery in my truck with still a fully functional bed and max seating. I was looking at the kinetic 1800 or 2200. Not sure how big I need to go but I'm pretty sure I can squeeze just about as large of a battery as I could find in the stock location.

so as stated, i'm still trying to figure out the best amp to get for my subs. i am in search of an amp that will push 1500 rms at 1.5 ohms. ignoring price, just curious as to what amps out there will push that power at that resistance. thanks

Hey there guys just needed some advice on my electrical. I have a 110amp stock alternator and i am running 2 12s skar vvs off a sundown saz2500 @ 2ohms so there getting 1200 rms. i will be running xs flex 0 gauge with a odyessy pc 1500 underhood. I am also running a skar 80.4 with front/rear skar coaxils. Wanted to know if my electrical is sufficent and another question was that using my sundown amp at 2 ohms, will that be less stress on my electrical rather then 1ohm? Thank you

Has anyone ever dealt with or heard about Motor City Remanufacturing Alternators? I know someone that is selling one for my explorer and would like to know how reliable this company is. http://www.motorcityreman.com/index.html is the website Any input would be greatly appreciated!!

Hey guys, I came across a USA 442 and picked it up for a real nice price. Before I did, I wrote to US Amps and asked for some background on the amp. Someone named Jeff Coleman replied and gave me some info on the amp..... some power specs, production run, etc. But, he commented that the 442 had an interesting and complicated crossover and that if I couldn't get an original owner's manual that I should run an outboard crossover with the amp. Anybody got any comments? Advice? Experience with the amp? Thanks in advance.

I am doing the big 3 on my 2004 Rodeo and have ran into a slight snag. I am hoping somebody on here has some advice. I am using 1/0 AWG weling cable from Airgas (Radnor Flex-A-Prene) . I Grounded the negative battery terminal and the engine to the chassis without issue. Now I am trying to attach the cable to the charging post on the alternator. The problem is that the charging post is a tiny bolt, and the lug on the welding cable is huge (http://www.airgas.com/browse/productDetail.aspx?Category=14&product=RAD64002143). The lug is too thick to be able to re-attach the nut on the charging bolt, and it is coming in contact with the case of the alternator where …

I bought a SAE-1200Dv2 and i have it hooked up... i am running two alpine type r 12s duel 4 ohm voice coils at one 1 ohm and the amp keeps shutting dow... it will play for a while and it shuts down and gos into protect.... i turn the volume down on my HU and turn it back up and t works... what could be causeing this...? any one know?

The car is a Mercedes CLK55 2001, I have 2 amps 1 is 300 watts(150x2@4ohm), one is 1300 watts (1x1300@1ohm). For a total of 1600 watts. I have a Kinetik Power HC1800 as a second battery witch is to NOT let the lights dim if the system is under 1800 watts, unfortunately it does dim in the cabin and the amp for my front speakers sorta cuts out at loud volumes. once when i went from drive to reverse it didn't engauge and i had to put it in drive lower my system and put it in reverse, this has only happened once and i was beating really hard (i have not tried this again nor do i want to). I had a lexus 2002 ES300 before this and i did not have this problem, same setup. The 2n…

Hey guys quick question: I understand this: Voltage of the output = sqrt(RMS Power X impedance of the speaker) Example Say the amp provides 100WRMS into a 4 ohm speaker: Voltage = sqrt(100W X 4 ohms) Voltage = sqrt(400W*ohms) Voltage = 20V So I have a 1500W amp and two dual 1 SSD12s. Would it be? Voltage = sqrt(1500W x 1 ohm) Voltage = sqrt(1500W*ohms) Voltage = 38.7V Should I use 30HZ, 50HZ, or 100HZ tone?

When my car is running, and my HU is on pause, I get this high pitch sound through my speakers. its there when a CD is playing to, but high volumes cover it up. Anywanyz, im trying to figure out how to fix it. Someone suggested to me to check the grounds. SO I did, and found that my battery terminal (-) was loose. After secureing it, I thought it had been fixed, but the next time I went out to my car, it did the same thing. This only happens when my car is running, not when im on ACC. If it was still a ground problem, I would hear it when im on ACC too, wouldnt I? Also, my lights, and my HU backlight dim slightly and brighten, all in a very fast movement. I have upgraded …

just wondering what everone thinks about the kicker 10zx700.5 amp or kicker amps in general? its on sale at crutchfield for $320 free shipping and i was thinking about picking one up since i was going to purchase a four channel amp soon anyway and i am looking to downsize my sub stage(currently running a saz 1000d at 1 ohm and was planning on running it at 2 ohms) and i wouldnt mind having everything all in one any thoughts or comments welcome.

havent been here for a while, just been caught up in school and what not. Need some questions answered. I want to put a yellowtop in the back about a foot or two away from the amp. KX1200.1. How would you go about doing that, I'm thinking a battery isolator to keep from draining either battery when it's turned off. What gauge would I run to the second aux battery? Where would I run it from? The isolator? The alternator? I want it to charge along with my starter battery so it doesnt stay drained if I listen to it for long enough. Do I ground the second battery to the floor or back to the original battery? I really need some help so tell me everything you know about …

I have a mechman 240a alternator with a xs power d5100 upfront everything wired up and running smooth. Now when installing my rear battery (another d5100) should I run both power and ground wires to the back battery or just the charge wire and ground in the trunk? Thank you in advance.

Hey new here. So i own a skar 1500.1d. Have it hooked up to a sundown sa10, and works great. One "issue" ive ran into is when i turn the bass knob halfway up it gets loud (obviously). But anywhere past that it doesnt seem to get any louder or gain any volume. Im confused as to why it does that. I have tuned everything with the SMD-DD1 properly so im confused atm. I had a thought that it might be because i tuned it at 0db but im playing -7.5db music. But technically speaking there shouldn't be a "cutoff" point in volume. Any feedback would be helpful.

I installed my Alpine 9887 the other day and plan to mostly use my Samsung Galaxy to play music with it. I bought an AI-net to 3.5mm jack to plug the galaxy to where the CD changer would normally plug into. Here's the problem; it plays music, but no matter what source I have selected on the 9887, so it plays over the CD if the deck is playing a CD. If i select AUX in on the deck it only plays the Galaxy's music, but my subs don't seem to be playing at all. I've got AUX turned "on" on the deck, and the digital AUX turned "off". Sub level is turned up to 15, they play fine while playing CDs. Would swapping my AI-net -> 3.5mm jack to a AI-net -> female RCAs and adding …

will a audiopipe 3000d see 1ohm as a daily driver?

Cant decide which amp to get for a 10" Fi Bl with BP Power and Flatwind coil. It will be ported @ 33Hz under the rear seats of a ford f150

Does anyone here know who makes Digital Design amplifiers, and are they worth the extra money?

Have an opportunity to purchase a 250A Ohio Gen alt to temporarily bandage my voltage. Has anyone ever used their alts? I heard they put out straight poop @ idle so that is why I am worried. My car idles at a very low RPM: 2004 Pontiac Grand Prix

Just wondering if anyone has had experience with this welding cable at 1.50 a foot for 1/0 its very enticing. http://www.cableyard.com/catalog/product_info.php?cPath=21&products_id=32

When I installed my alt. it metered out at 14.9 at idle at 260amps. Driving home today I noticed the battery light came on... As soon as I pulled in the driveway I slapped a DMM to everything! Now on all my points I read 26.5 to 27.3 volts....WTF!!!!! I haven't touched a thing since I installed it. What in the hell would make this alt decide it now want to spit out almost twice the voltage? I'm yanking it out for now and putting in the stock alt...(I know it's good) I've had issues with this thing since day one with the annoying whine it puts out of the housing..... Besides the noise it worked excellent...UNTIL NOW!! Any advise would be nice if anyone has any input.. Than…

I need any assistance finding a manufacturer to make a dual alt bracket for my 2011 4runner SR5 4.0L V6 engine. I am in the process of purchasing components for an audio upgrade and would like ti run the truck off the original alt and the sound system off the beefed up(350 amp+) second alt. If anyone has a kit available please please contact me through this post or message. Thank you in advance.

I have a '97 Grand Prix with a 220amp alt. and a 1.5v booster on it. I have a SAZ3500D BNIB, and will be picking up my 15" SMD in a week. I already ran the big 3 with 0 gauge and 2 runs of pos. & neg. to the back. Now I am looking at atlernators, should I get a 300+ alternator or can I run another 220amp alt. ? I can get another stock rebuilt to 220amps for about $200 and I know a couple welders that want to build a dual bracket, they are hard to find for a 3.8 V6, as are 300amp alts.. If I do get a 300a alt can I get by with just that one? And what are some suggested batteries for each setup? THANK YALL FOR YOU INPUT! I did try to search for my answer...

Hi, I want to uppgrade my stock system. I need a pair of 6.5" component in front and 2 12" woofers in the rear. My ride is Renault Trafic van. Can someone advise what and which model of the RF family to buy. I believe I also need some amplifiers, capacitor and accessories to go with. Thank you very much

I've been thinking about buying an Oscilloscope for a while now. What should i be looking for when it comes to buying one? What makes one durastically better than the other? For know it will be used solely for setting gains to insure minimal clipping, but I would like it to be able to do whatever else one would do with an Oscilloscope. Seeing as I'm an Electrical Engineering major I know it will most likely come in handy in my future so I would like to get one that has a wide range of uses. So what should i be looking for when it comes to the specifications of an o-scope? Thanks for your time.
