will i need to run a relay between my starting battery and a kinetik 600 in the trunk? if so, what size would be needed?

About ready to start putting batteries in this compartment in my car and need to line the wall with some sort of padding so the batts are not just wedged in there around wood. I figure I might as well go ahead and get something that can keep this compartment somewhat warm so i can have the edge in better performance during the cold season for when I compete. So, any thoughts? For the side walls, i have about 1\4" gap on each side of the batts for reference sake. Front and rear, I have 1 1\8" gap in front and behind batt bank. I also have room to put something under them as well but if i do , it must be severely thin, like 1\8" thick, no thicker.

I have the big 3 done, double runs of 0ga, sundown wire 270 alternator , m4b amplifier 3 3400 xs battries in trunk volts are at 14.3 but when up loud bass note hits and volts drop to 10 showing on bass control knob....p.s. Digital design 9900 series subs are wired to .5 ohm Do I need more xs battries ???

I have a complete budget system that I will be starting as a little project for me. Im a senior in High school with not much money to spend so I'm looking for opinions on a nice budget Amp that will give out about 1-1.5k rms power at 2 ohms (it'll be running to (4) 4 ohm subs). My budget would probably have to be around 150-250$ give or take a little. I'm open to all opinions and come here to ask you guys since no other reviews and forums don't have as much knowledge as you guys . Thanks

I can't for the life of me figure this one out. The power and grounds are both good according to my DMM. The remote wire is getting power (0.1-0.2v) The remote wire is hooked to the blue and white wire. I've tried 2 amps, 2 fuses, and 2 capacitors. DEX-6900BT Pioneer radio Hifonics ZRX3216.1D Zeus and also tried Skar Audio RP-2000.1D (thought the amp was bad). All the other speakers and such work, so totally at a loss.

the amp will be running 2 sundown audio sa-8v2 when i get then on a stable 14.4 volt system big 3 done stock alt and stock battery for now till i get the xs power and all 0 gauge wire with and an eq and the other odds and ends

Hi guys, I have recently been saved by a cheap voltmeter plugged into the cig-lighter 12v input. It showed me I was loosing voltage badly. I found something was burning under the hood. The plastic on the wire coming from the positive post on the battery to the alt was bad, and the cooper was touching a metal part. I took it off, and now everything is ok. The alternator works as usual. But now I want a better voltmeter. This one is 8 years old ! I want something small enough to fit anywhere. I won't cut anything in the dash to have it mounted, so I liked the cig lighter plug a lot. Which model do you run ? And second question : if it's…

I currently have a Kenwood KDC-248u head unit and I think I want to upgrade it to something a lot better. Not exactly sure what hu I want so I am looking for some suggestions. Budget is $400 but I definitely would like to get something cheaper if I can. Thanks -JP

Hey everyone, I just got my o scope and decided to tune my system. First i did the door speakers since they are ran off the HU, and found I have a max volume of 31/50, all the sine waves looked good, went smooth as butter.... then i went to the sub amp, brz1200d, and i have the weirdest thing showing up on the scope. a picture will be below, or a link. i have eliminated the rca's, hu, and almost all factors with this. even with no signal going to it, and just the amp on, no rca's connected, no bass knob, and i still get a feedback.... please help me figure out why this is happening, i dont want to bump my sub till this is figured out.

I have been thinking about making some quality Big 3 kits, and just want to kind of take the forum's temperature about the idea. Ordering will be easy, simply give me the three lengths you need from mounting hole to mounting hole(for me, this will = terminal hole to terminal hole). Here's a rundown of the parts/process. 1) Wire being used will be the new black Audio Technix 1/0 CCA wire. 2) Terminals will be tinned copper to resist corrosion. 3) All wire/terminal connections will be crimped via a hydraulic crimper for a connection that will never wiggle loose or back out. 4) All connections will be finished with some black heat shrink tubing for a clean look. Do you guy…

Can anyone tell me a good less expensive 4 channel amp i could buy for my coaxil kicker ds 6.5's? i am looking at a kicker zx. 200.2 now i relize thats a 2 channel but im tryin to keep in my budget.

Which is a better amp? Apsm 2500 Apcl- 18001d Both have good power ratings for my sub but what's the difference? Which is more efficient? Just trying to decide which to buy.

Alright guys so this is my first "big" system. I have 2 soundqubed hdc3 15 d2's in a 10 ish cu ft box tuned to 32 hz. I have 2 soundqubed q1-2200 amps. I plan on strapping them. My mids and highs I got on lock so they're not important. I have a 180 amp ho alt by singer alternators. This is the absolute biggest he could make it. 1 xs d5100r under the hood and 2 xs xp3000's in the back. Nothing is installed yet I'm waiting for all my install accessories. Do you think I have enough batteries and is my alternator sufficient enough to handle 500 amps of max current? I'm waiting on my xs charger to come in to install everything because I need to fully charge my batteries. Also…

Gonna buy a single 10" or 12" X or Icon, which ever pops up in the classifieds first. Will be in a .8-9 cuft fiberglass box sealed, polyfilled 1-2lb iirc. This is an under seat setup for a 4 door dodge pickup. I've seen the black ice has been proving a decent amp for the money. Just want to get any last opinions or reasons to not get it and go with something else. I don't want to spend more than $200-250 on an amp at the moment. Thanks!

I can pick alternators for $20 at my local yard, for an extra hundred odd amps would getting a bracket fabbed be worth it? Not planning to exceed 3k rms for a year or so. Just a hifonics brx 2k and a taramps 250x4. Suppose I'm askin, how much would a bracket and a longer belt run me?

I have a soundstream XXX4000d is this amp worth anything? I have it currently on my 12 inch warden and I am not feeling the power or seeing the numbers that I should be. Is this amp junk or am I missing something. I have 3 batteries, a 220amp alt and the dual 0 gauge inputs going from the batteries to the amp. The sub is in 3 cub with a slot port tuned to 47hz. I am only at 145.2db and we tuned the box for the rez freq of the car.

So the speakers I am getting are the Lanzar MX8124, I will be getting two pairs, but I need help choosing the right amp for them. Any help is greatly appreciated.

I have this head unit and all my basic setting are here but I see in videos of the radio the settings for aux and stuff. My radio won’t let me connect bluetooth I can only listen to fm and cd’s Someone please help these are the only setting selection it’s allowing me

i guess you guys got the topic right since iggy knows all about big head units man, the forum is dead so i am just being a bored post whore

Whats up guys this is Rp i own a car audio shop in Lafayette IN i am running street c this year and looking for new amps... currently using 4 Memphis 4kw and pro-comp subs. looking at the 3000 watt ssa but i need test results on them... volt drop\ power\ ohm\ and amp draw

Im getting 2 amp kits from knukonceptz. They are both 0 gauge. One is for my amp wiring and one is for my big 3. One of my questions is when my battery grounds it grouds to the frame and the block. Do i need to replace both? And where should i look for my block ground. Btw i drive a 2004 Isuzu Rodeo 3.5 liter. I run a kicker kx1200.1 and its pushing a kicker L7 15 D2. Any advice would be greatly appreciated.

Well it took me forever but i got my 250 amp Mechman alt in this weekend, had to get a different size belt to run it... well problem is my car is sitting at 11 - 11.3 volts!!!! even with the stock alt it would hit 14... i dropped a pretty penny on this, and its way worse than my stock. i have had the big 3 on for 6 months. is this bad for my car? i have a long road trip coming up ion a couple weeks and this needs to be fixed. whats my problem????

im thinking about ordering one of these amps to power my mids, i would like to know if any of you guys have used this amp and what are your thought about it and if it does rated power. thanks

Hello ppl does anyone onwn this amp I want to purchase one from the net...How good is the sound quality ? I'll be using it on coxials speak. or can someone also recommend me an amp let's say about 50 rms per channel .... and budget around $150 thanks to all

Anyone know anything or had first-hand experience with these amps? I'm looking into buying one based on rep, but haven't had a listen to them. Any info is welcome. Thanks all.
