I have been playing around with my kenwood deck lately and want to make use of its USB direct control thing. I like the idea of getting the numerous CD cases out of my car and being able to control it all off of my deck. the only problem is, whenever I play music off of the USB, it looses sound quality... (volume drops and the bottom end sounds weak). Why would the same song sound great from a CD but sound bad from a USB? Is it suppose to be this way? Also, would the 3.5mm aux imput sound just as bad? I really want to figure out how to get rid of all of the CDs in my car so any advise would be appreciated. By the way, the deck is a kenwood KDC-MP538U Thanks Alex

Hello everyone. Had questions about how to tune my amplifier. I dont want to start slammin the BL and have it go out on me. Let me say first I have done my Big 3. Running 1gauge to rear battery. 4 gauge to amps. I have a good idea on how to set my amp gains. I read the HOW-TO here on the forum. What I need is how to tune this knobs on my JL AUDIO amp that I havent a clue what they are. First would be my infrasonic frequency(hz) knob. It goes from 15 to 60HZ. Also there is a on and off switch for that. Second, there is a Parametric EQ setting marked "Q". This setting can be tuned from 0.5-4.3. I belive its the bandwidth control. Anybody know for sure? What should I set my…

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.

Is the DMM method a fairly accurate way to measure the watts output of an amplifier? I set the meter on AC volts, connect leads to speaker terminals (w/ subwoofer still hooked up), play a sinewave burp and take that reading to determine how many watts went to the sub. Does that sound correct? I already set the gains w/ an o-scope so I'm not trying to do that. I want to calculate how many watts actually is going to my sub thanks

Has anyone seen or have this.I would like to know if its worth the money.alil pricey for my taste

okay, so where to start.. I have a AQ2200 in my GMC S15 ext cab. The other day it was working perfect, i unhooked the amp (while batt disconected) and took it out because i was removing my seats+subs w/box and going to shampoo the seats and where the amp is located i didnt want the seat brackets to bang/hit against the amp. Well i cleaned everything and put everything back in and everything LOOKED like it was working fine but.. there was no sound comming from my speakers... so, i recheck all my wires.. once, twice, and a third time.. i unhooked and hooked the wires to the amp again.. no sound. I switched the + & - speaker wires in different inputs of the amp.. no soun…

have no clue how to even start but am woundering how to convert my 12v to a 16v system ? what is all requierd i don't have a budget as of yet but i am also wondering how much aproximatly it would cost.

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 I am tired of having multiple thumb drives and wanted to used and external hard drive. before I go buy one and download a bunch of music will this work?

do knukonceptz give tracking numbers??? i ordered some cables this afternoon, and after i checked, it only said processed, so i dont know if that will change or will the ups surprise me at my door

im going to purchase one now so which would be "better". this is one part of the upgrade im going to get 2 ssa icons d1 and wire each to half ohm so i need help choosing which one max looking for $500 on an amp.

hi guys, never had any experience with audioque Im thinking of getting a aq2200d and a 15 hdc3 for now any suggestions,experience,pros cons would be greatly appreciated!

I just recieved my new Fi BL 12 and am looking for an amp. What would be best. A used audioque 1200d, new audiopipe 1500d or a new soundstream 1200d. Sub has flatwind coil option only. Dual 2 ohm

Hi, I am selling my 4 channels Boston amp. I can make a good deal with it, and I don't use rear speakers no more ! I need a small (in size) 2 ch amp to power my Focal 165 KP. I need about 2 * 100 watts rms or even less, and my head unit is good enough, so I don't need lots of features on the amp. The problem is the budget : I want a really cheap amp! But I want a brand new one. The Sundown 125.2 would be good, and would match the sub amp (a saz1000), but I would like it cheaper. I saw a Cadence Xa 175.2 xenith series at Powermax electronics, it looks good ! There is an entry level Rockford the R 300-4 (I could bridge it) that seems good too.(Powermax electronics) One poi…

Simple question really. I know setting your gain with HU at around 75% is going to give you the best voltage output without distortion from your HU to your amp. That being said, with my current Grand Cherokee Limited infinity stock speakers 75% sounds like ass. (stock speakers get too loud) Btw, I'm setting the gain for my sub amp a RD 1750.1 at .5 ohms to a Treo SSX 12 with a Shuriken BT100 in the back. All 0 gauge and big 3 is done. HU is Alpine CDA-9886 with Subwoofer level and Bass/Treble. Also has a HPF which I'm not too sure actually does anything. I thought it would keep bass from going to my stock speakers? That's besides the point. Basically, my question is if …

on my highs amp, im running the power wire as 8 gauge and the ground wire as 4 gauge(i was told this was ok by a friend and professional installer). im not doubting his credibility, i just wanted to know what are the advantages and disadvantages if there are any to wiring your amps this way

well i am looking for a good brand after market alternator, if you know of any help me out,

Hi Guys, Are the Audioque amps ( 2200, 3500 ) good amps or not ? I what thinking maybe someone out there has tested one the website numbers look good.

Looking to get a new 5 Channel Amp, right now I'm Looking at the Alpine V9, JL 900/5 and the Arc Audio XDi850.5. Is there anything else on the market I should be looking at? I'd like to stay with in the 700 - 900 watt range.

I finally got my system bought and all put together today!! 2 2 0hm 12 inch L7s Kicker zx 1500 streetwires powerstream 0/1 300A anl fuse optima redtop so the problem is... i turn my truck on, system turns on fine, as i turn the bass up, it shuts off, i turn it down, it gradually comes back on after a few seconds. And does the same thing each time. i grounded it to the seatpost bolt ( which i found out briefly agok, IS NOT ATTACHED TO THE FRAME) i Wired the subs down to 1 ohm each, equalling a 2 ohm load, but the weird thing is, is that the12volt.com said to wire it one way (for 2 ohm load) and kicker said to wire another way?????? so i went with this way- as oppossed to …

Basically I cannot get any pre-out voltage from the HU for the sub-out. With volume all the way up on a 50hz tone pre-out voltage is ~.69 (tested directly at the HU). Put the leads on the mid output... .69 as well. Put on a 1khz test tone.. DMM on mid outputs... 3.69... on sub with 1khz.. 3.69. So basically I'm pretty sure nothing is wrong with the actual pre-outs but I am missing an option or control on the HU completly. I have the Subwoofer set to +15 and it's set on Subwoofer system 1. The Crossover and PEQ don't have the level turned down on the sub... so I am
