im stuck... help me. both 1 ohm daily .25 burps. on 300 mechman and 3 dekas

Hi there I just bought a 15 inch nightshade and need to pick an amp to run it. I want to get an amp that can run it at 2 ohms. Money is a lil tight,.. I was thinking about a hifonics brutus that does 1700 at ohms or a Power acoustics that does 2600 at 2 ohms, these are affordable amps but i dont know how good they are or if they over heat i would love some suggestions or links to amps that can run a 15 inch nightshade and get it LOUD without over heating or messing up the battery or alternator and is efficient and all that.. if someone is selling an amp that can push this sub please let me know. thanks!!

So I picked up a pair of Hertz Hsk165's and need some help with choosing an amp. Amp will be ran off of a kenwood 8120. I have about 400 to spend... but I wouldn't mind spending less. Im thinking about the following: sundown sax-125.2 $240 (even a 50.4 bridged thoughts???) audio systems twister 300 $300 jl 300/2 $350 steg K2|02 $450 arc ks300.2 $399 what are your thoughts on the ones posted? any recommendations?

Hey guys, I bought a jeep wrangler and the previous owner added in a new HU but decided to be cheap and hack the wires together rather than buy a harness. Every time I shut the jeep off, the radio shuts off, then deletes all the pre sets. I bought a new HU, hooked the wires up, and the same thing happens. Shut off the jeep, bam the HU resets and goes through the initial set stage. What is causing this? Bad ground? I'm stumped.

I'm looking for a solid amp for my mids and highs, 125-150 rms @ 4 ohms. A friend of mine is pushing me towards the Jl 300.2 but I know there are cheaper alternatives that are just as good. I'd like to keep the price around 200-300$. Thanks for any input!

So today i turned on my car while leaving class and decided to bump on the way home. Well i couldn't because my sub wasn't working. It was working before class. I got home and hooked up my other working sub which i decided to upgrade from (VIBE slick) and that did not work either. I know for a fact that the vibe isn't blown and my amp tells me when a sub is blown, wired wrong etc. The amp said everything was fine. So i hooked up my old amp (a kenwood) and that amp didn't work either with both subs. I can't stress enough that the VIBE is a good working subwoofer. I checked all of my fuses under the hood and none of them are blown. Neither are the fuses on both of the amps.…

I'm looking at getting an 18" btl to put in my jeep, i have box plans, but i am also looking for an amplifier. Has anybody ever heard anything on Planet Audio, or do you have an idea of what better amp I should get to push just one 18? EDIT: I'm looking at the Planet Audio AC4000.1D Amplifier

I was wondering, are Audioque amps comparable to Sundown amps?

I just saw a post from xspower and one of the questions answered was it's ability to be used as a starting battery. I want to pick up a shuriken to replace my starting battery and was just wonderin if anyone uses them as a starting batt or if they are able to be used as one. I've read they are similar to kinetiks and saw those being used as starting batts. thanks.

Ok so I installed my Stinger voltmeter last week and tuned it or whatever with my multimeter and it works perfect,.. but now that I can watch my voltage.. it is weird. Sometimes when I am driving it goes below 12v.. this is even if my head-unit is off, no windsheild wipers, no headlights no ac.. nothing on just driving and it randomly went to like 11.6 even.. I have figured out my "normal" voltage when driving is usually 12.5-12.7v... like that's what it stays at most of the time.. but when im driving I notice it is randomly at like 11.9 then later its like 11.6 and its for like 5-10 mins sometimes and then sometimes it goes back to like 12.2 or 12.5 and just fluctuates a…

I am buying a yellow top from my friend. It is taller than my original battery and the wires won't reach.

I own a 2003 sunfire which currently has a 105amp alternator. I was looking to run about 1300rms off it, but I know the alternator isn't big enough. The problem I'm having is that I can't find anyone who builds a high output alternator for my car, and I looked into getting it rebuilt, but I can't do that either. I don't know what to do. Are there any specialists for problems like this, or am I screwed?

hi ok right now i have my 2 hifonics brz2400's hooked up daisy chained... 1 set of rcas from the cd player to the input... then another set from the output to the input of the other amp... then same way with the remote... now i know you can link/strap these amps together... i was wondering will it make a difference if i decide to strap them together instead of daisy chaining them... will it give it more power or just be the same ??

can i power car amplifiers in home using a lab dc power supply?

i was really close to ordering a Pioneer AVIC-D3 for the Mini. well, its 700 shipped, 6.1" screen, navi, etc. for a couple hundred more, why not get a carPC? so im doing just that. i ordered the 10.4" samsung VGA touchscreen. i need to figure out the PC thing now. im mostly concerned with the audio output. im going to keep my Head unit, and run audio out from the PC, to red/white aux in on the nakamichi HU. then sub/front/rear outs from the HU, to the EQ, then to the crossover, then to the amps. my question is, if the audio out on the PC is a standard 3.5mm jack, would is sound bad if i ran 3.5mm out from pc, to red/white aux in on HU? (i ran my ipod this way for a while,…

Ok, i've never ran multiple and have come to a barricade here so fill me in. 1 battery up front, 5 batteries in the rear. 400A for bass, 90A for mids\highs. Total Amperage fuses needed- 490A ~ 500A. Ok, first off- I'll have 3-4 runs of 3/0 wire going from front battery to rear battery bank. Right now, i just have 1 3/0 wire ran which is fused with ANL fuse and no fuse at other end because everything is dismantled right now. With 3 runs, i was going to attempt to use a bat terminal that had 3 1/0 connectors on it. I run the alternator to one of those leaving 2 left. The factory electrical wiring goes into the other slot leaving one left. I'm assuming i'll use a distro blo…

so mostly everyone knows about clipping, when the music gets turned up and it hits a bass note, starts to play it then quickly drops off. well i've been having this problem ever since i got my new setup and i've read the how to set the gain of an amp thread, done it. no change and i've tested the impedance of my vioce coils and they're correct, dual 1s i've tested the ohms on the output of my amp and it's reading 2 flat which is what it's supposed to be i've re wired my sub to the amp and checked my rca's but it still clips when it gets turned up. any other suggestions, please?

Anyone here has experience with these head units. I've only owned pioneer so don't know how reliable the JVC's are. The model I was looking at is the KW - AV71BT

I have a 2.2L 2002 Oldsmobile Alero and am having a tough time finding a high output alternator bigger than 150amps. I'm just wondering if somebody has this car and purchased one, I called a place and they said an alternator made for a 1999-2002 Chevy cavalier MIGHT FIT, so that's a take a chance and hope you're right. I am running 2000 watts right now, my alternator fried today and have been searching for hours trying to find one but nothing comes up. I figure I might as well get one now instead of wasting $100 to get a new 105amp one. Otherwise would a second battery work after the big 3 upgrade? I have 2 1000 watt alpines and 2 pioneer premiers ts-w3004spl but will be …

Which is the best solder type?

I just switched out my old Kenwood subs and 500 watt amp for 2 12 in icons and a bc2k and there is almost no output from the subs. I didn't change any settings on the head unit and I double checked the wiring they are wired to 4 ohm so I should see 700 watts. The amp is on and not in protect. The bass is so quiet that the factory speakers are louder. Anybody have any ideas on what could be wrong?

So i just put a new battery on my wifes yukon like 6 months ago...and i turn it on now and the voltage drops very rapidly..i turn on just the switch with the truck off and the voltage goes from 12.3 down to 10.6v is it the battery or is my alternator not charging it right? Its the stock 160a alt...
