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 …

I have 3 of the old rockford 200x2 transana amps 2 of them i bought from a guy that swore they worked fllawlessly. Anyway I hooked them up to test them out, they paly fine until they have to play a low note, and then they clip i guess, until i turn the volume down a little and then they play fine. The other 200x2 I have doesnt do that at all I can play it all day long and it never does that. has anyone ever heard of such a problem?

Hey guys, i seem to be having a few problems with my system just a couple days ago and i was wondering if you guys have any idea of what might be going on before i go searching for the problem myself. I have 2 12" FI Qs running at 600 watts each, so an overall of 1200. Just a couple days ago i was testing a few songs on the system, nothing out of the ordinary, everything was working fine. I've has this system for about a month now and no problems occured till recently. Then a day went by where the car was idle, and then the day after that the car wouldn't start; the battery died. I couldn't figure out what happend because the car was completely off after the day i tested …

Is there a preferred method in setting multiple gains/levels??? Stuff like: 1. Radio's subwoofer, line-out-converter, volume controls 2. Sound processor input/output/levels 3. Amplifiers' gain

Well guys my avic's outputs took a shit today. Have a horrible alternator wine no matter what i do and its putting my 1500d into protect. Plugged up the ipod to both amps with the car running and no problems with either amp. Ive tried everything from different rca's to different remote wires and nothing seems to work. you guys got any ideas?

i was thinking of adding a mp3 player to my car, i was either thinking ipod mini or creative zen micro, im leaaning toward zen micro now and getting that napster to go and just fill it up with songs, which is hard to beat for getting most any song on there(unless anyone has used it and can say different) although i would like an ipod because of the adapter that will show what song is playing and i can hide the ipod and just use cd player, but no upload of songs with it , gotta buy them old fashion way or used p2p but i was planing on getting this http://www.crutchfield.com/S-F46N3x...asp?I=130CDRB10 for the zen or this for ipod http://www.crutchfield.com/S-F46N3x...sp?I=1…

ok im about to hook my system up an im gana put 2 batteries in the trunk there gana be in mdf boxes mounted to the trunk. do i need anything special to do this or can i just put 1/0 wire from front to back with a fuse by the front batt and one infront the back batt.

I just picked up an electronic xover and each of the 3 outputs have a "level" setting which I assume is like an amps "gain" control....How do I set that correctly? The manual does not specify how to do it.

I'm runing two ia 21 dp's I am trying to figure out what amp to go with a incriminator audio 40.1 or a Memphis 4kw if any one can help with the pros and cons of both please and thank you

i was adjusting things on my treo ssx250.2 amp and noticed their is an audible noise coming from the amp. sounded almost as if the internals were squeaking to the music. thing is i don't htink it' s the amp i replaced the treo temporally with a us amps amp and it did it also . i'v enever seen or heard this in the past anybody know what the problem could be?

I have a JX1000/1d and when ever I start my car it works fine green light and music bumpin. I turn the car off to take the bar off, turn it back on and its in protect and wont turn green unless I wait a long time. It only works first start up, I checked the ohms coming from the sub and its a steady 2.0 and also took all the wiring off the amp and put it back on, still nothing. Really pissed off Iv checked everything I can think, anybody have this prob before?

Okay, i got my amp and i know what subs im going to buy. Amplifier: Kenwood KAC-9104D Woofers: 2 x Fli Frequency 15 400W RMS each 1200W MAX each Single voice coil 4 ohms each http://akustika.ee/pood/index.php?GID=1971...mp;currency=EEK sorry this page is in another language but hopefully you get basic info if needed. Question is, if i wire these two subs in parallel the resistance is going to be 2 ohms ?

im going active in a month or 2 and i just saw some kicker zx100.2 amps on ubid.com. the bid is closing friday and i think i could get 2 of them for like $15 each (not including shipping). they are factory refurbs. ive purchased a kx250.2 from them previously. my idea is to bridge them to each mid and use my 250.2 for tweets. will this work? might hold off and try for a zx 150.2 or 200.2 next week...

What kind of wiring am i going to need, assuming 1/0 gauge? So far i have: SUB: Fi 15" BL AMP: saz-1500 ENCLOSURE: 3.8ft^3 @ 32 hz i have no clue how much and what kind of wiring i am going to need.

So my car has been dieing after sitting overnight. It won't start in the morning. I have been leaving it on the charger overnight. I have an Optima Red Top under the hood and a 55ah SR12-205FR Super Rate Series in the trunk. I took the trunk batt out at Autozone and the guy tried to test it and said it was at 10.xx volts and he couldn't run the test with it that low. He said that I have to do a trickle charge on this batt, it can't be charged with a regular charge. Is this true? Then we tested the red top (with the trunk batt still disconected) and it was resting at 12.41 volts and read as a bad batt. The Autozone guy said it should be around 12.45 volts and I should tri…

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…

http://www.crutchfield.com/App/Product/Ite...A465&tp=115 Link to the amp. I need an 4 channel amp that is 2 ohm stable and has variable cross overs. My fronts are Infinity 682.7s with stock 8" midbass in the doors. No rear speakers. I'm actually happy with the sound using my HU to power the 6x8s, but it is starting to die since the speakers are 2 ohm and the HU is not 2 ohm stable. I also want to be able to control the cross over points of my midbass speakers better.

I currently have a v1 sundown amp. If I wanted to strap a second amp do I need to strap only with a V1 amp or would it be ok to strap with a V2 model?

Do they make a complete dead heads? Like without any processing, internal amp. Basically a volume knob and a line out? Prices?

just got my soundstream xxx6500, on a trade for a componet set, what do you think about it? what comments do you have from people who have one or used one?! any suggestions? will two kinetik 2400 be enough power for it?

Has anybody had this head unit? I can't seem to find out how to set the bass, treble, mids, ect. It has presets but that's it.. Can anyone help me out?

I got a new highs amp from a friend of mine! Epic ass Audiosystems X-Ion 70.6 Plus!!!! Two fans on this side and two side on the other. A little fuzzy, but you get the idea.

Rockford Fostgate T2000 200 amp alternator or a 130 amp alternator if im going to be putting in another battery thanks

I'm trying to bring the shine back to my old SS class a amps. I've started on a few fins using eagle one nevr-dull. It comes out nice but takes forever to clean up. Anyone here have a good suggestions for cleaning up aluminum?
