So I was reading about my 2002 jeep liberty (KJ) electrical system and found this The charging system of our KJ's is much different to ones in the past. I have been told that in an efforet to protect the PCM and other computer components in the KJ, the charging system draws from the battery FIRST and then calls on the Atl/Gen to re-plenish the battery as needed. That is why the new generation of Deep Cycle batteries work so well. They have the reserve power to allow the extra toys without needing to add the huge alt/gen of the past. As you use your lights, stereo, winches, what ever, they will be drawing from a battery that is not designed to power all that stuff. A deep …

Looking to go active in my truck and have found one of these pretty cheap. Very budget oriented system, but would prefer to keep everything active. Does anyone have any thoughts on this beast? http://www.pioneer.be/be/product_detail.js...xonomy_id=25-38 It looks like it will work for what I would use it with: rli10" and a mid-range/tweet combo tbd

looking for a few different options to power a 10" DCON. Right now i have a Kenwood 9104D running at 12.2 volts putting out 402watts RMS at 4 Ohms. Should i stick with this or go another direction?

would love to have this power the 300ce system http://www.rockfordfosgate.com/products/pr...55&locale=en_US

i got a md1d amp from usamps it has a bass knob with a little led light in it does anyone know where they sell a led bulb that small so i could change it to a different color?

I'm looking to get a new head unit for my car and I'd really like something with all of those features. The specific model I'm interested in right now is the AVIC-F90BT by Pioneer. Anybody have any experience with it and/or want to suggest something better? The lowest price I could find on it was here: http://www.amazon.com/dp/B001BJ6JQS?smid=A...mp;linkCode=asn

i dont know if this is the right spot to post, but i was just wondering if there is anyone out in northern cali, the bay area, or near the vallejo/fairfield area, that has a O-scope that can charge me to set my gains on my amp. the right way?

going to be buying a 10" Fi SSD in the very near future. but i need some help with buying a good amp to power it. i'm looking for decent quality for a decent price. i have no idea where to begin.... any help you guys can give is awesome....

alright so i have a cheap walmart wet cell battery under the hood.... now i bought i xs power d3100 to run my amps off of in the trunk.... can i wire the 2 batteries parallel together or should i just run them seperate to the alternator ?? if i should run them seperate how should i do it ?? i wasnt sure if i could run them together since one is a wet cell while the other is a dry cell. i wanna run my cars electrical off of the walmart battery and the amps off of the d3100.

Hey I'm looking at 2 MA Audio Amps... on this amp it has a sub sonic, bass boost, LPF, and GAIN I know i turn down the bass boost, and the GAIN all the way down while setting gain.... but do i need to turn down the sub sonic and the LPF? and what exactly is LPF.. thank you!@

well i got robbed back in july in addition to hu being taken the radio bezel was also ripped out along with harness. so im getting ready to get another hu, possibly the same one (pio deh-p4900ib). i was looking at the wires yesterday and none of the wires looked familiar to me. so my question is how would i go about running the hu off the batt? i know i can ground(black wire) to the - and yellow(batt) wire can be wired to + of battery. how do i wire the red(ignition) wire? somebody chime in and let me know what i need to do safely step by step. this is going in a 99 mustang if that matters.

Okay guys, i am looking at kicker zx750.1d its about 229.99 i was wondering if anyone knew of an amp thats just as good but maybe a little cheaper? any suggestions let me know! Thanks, Austin

ok ive been looking throught the "big 3" posts and i understand everything except for the block to chassi ground i cant seem to find the stock one on my truck. if i cant get to it what would be the easiest way to do this also would it hurt anything if i ran 2 1/0 from alt + to batt+?

Just got a call from my dad and he's been having problems with his OEM HU and Cd's getting stuck. Chevy Silverado 2005. Can someone help me with this situation and also provide info on how to prevent this from happening. Thanks!

What kind of amp(s) would be best paired with 2 FI BL 10" subs and should i go dual 1ohm vc or dul 2ohm vc

I'm new here so bare with me. I have 2 power acoustic mofo 124x 12 inch 4 ohm dual voicecoils subwoofers running at 1500 watts rms each (3000 watts rms together). They are both wired parrel for 2 ohms each and wired to together at the amp for 1 ohm. I have a skar audio RP-4500.1d mono block amplifier pushing these subs. My question is do I need to upgrade my charging system to 2 high output alternators and 2 batteries along with the big 3? I did the math with the ohms law and just for my audio system alone I need 450 amps. I figured two 300 amp output alternators should be plenty. Am I right or is this overkill? If I'm wrong help me and gave me some advice on what I shoul…

http://www.soundsolutionsaudio.com/store/products/Incriminator-Audio-I-Series-6.5%22-Components.html So I bought a set of these. Just wondering what peoples opinions would be on a amp thats roughly 75x2 (figured that cus it seems like it'd be more common that 85x2). Size isn't really a problem. Looking to spend 50-100$. Know thats not that much but really just want something better than running them off the head unit. So what do you guys think?

Well, I have been watcking egay for another 275 board, I have been seeing them quite often but never had the money. Well guess what, found another. My plan was to have both amps and make 2 plexi covers with fans to show off the internals. If you guys cant tell I love 2 things and 2 things only, Cerwin Vega and Old school Orion. Gonna wait untill closing day of auction before I bid. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewI...5750172292&rd=1

What are you guys' thoughts on this? It is sort of temporary give or take on how much I like it, I don't like the looks too much but it seems like its fine. I like having the noticable volume and channel changing button also. The USB I have read that you can plug your iPod through the USB and it should work (if it doesn't I have a flash drive or can get a bigger one for ~10$) and it plays cds. I have an iPod touch and I haven't been able to use it because the wireless ones dont work for chit (and differ in each car), I have no tape deck, and all I can play are cd's. This unit also has 6v pre-outs with front rear and subwoofer RCA inputs. (I can use them for my subs) I als…

well thing is i had my alternator guy build me a high power one for my truck and for some unknown reason at times, mainly early in the morning when its cold out still my alt will be charging from 14.4 bouncing up and down to 15.5v ive takin the alt to my alt guy and he put it on the bench and said it tested good no problem... well thing is it only does this early in the mornings every now and then, but later on in the day it charges normal 14.4v just fine. i got no warrenty on the alt so anything that he does to it ill have to pay for. so if 15.5 wont hurt any of my equipment ill just leave it alone for now, otherwisee i gotta pay him to put anew regulator in it and just…

So say i set my gain at 50%, if i dont even plug in the remote knob, obviously the amp operates with 50% gain. But if i plug in the remote knob and set the knob to 100%, given the amp's gain setting is still at 50%, will i have identical output? or would i have to reset the amp's gain setting with my dmm? From what i understand, the amp's gain setting sets the maximum level of gain, and the remote adjusts the percentage of that gain setting you want to use. i.e. you have the amp gain set at 50%, and the knob at 50%, so you'd be using the equivalent of setting the amp's gain at 25% with no boost knob correct?

I just installed an avionixx 440.4 amp into my rsx and I am hearing 'static' distortion coming through all my speakers. The distortion, though slight, 'plays' along with each note of the song if that makes any sense to anyone. I was thinking of adding a noise suppressor but I am not sure if that would be another waste of money. I am begining to think perhaps the amp is a defect or just not up to snuff for the job (quality-wise). Here is what I have tried thus far: -Ensured secure ground to the vehicle chassis using 4 guage cable (same gauge as power line). -ran rca straight from the deck to the amp thus negating any possiblity the other rca's/speaker cables could be cau…

it got very cold around here and like many others i just bought two new batteries for my truck, these are just factory but AGM upgraded. now in an audio system lets assume i have enough wiring to transmit power with negligible losses from under hood to back seat. if i have two batteries at 1150CCA up front and put an older battery in back on the amp rack (say a 900CCA agm) will i run into issues with having a less than new battery back there? lets say the battery tests out at 80% of its rated cca (so still a decently good battery i think), when the amps pull power will it have a similar effect as a cap can have in that the alternator is now trying to charge the batter…

Does anyone know of a standalone subsonic filter you can buy? My friend bought a Kicker ZX700.5 and it doesn't have one... But he doesn't need a full audio processor or crossover, just the subsonic filter. I'm looking for something that preferably hooks into the RCA's, but if there are any other options please let me know. Thanks for the help

Is there a way to find out how much room is left in the alternator output after running the vehicle? I am just wondering if this would be a way to see or prevent power drops and messing up the car/truck electronics.
