Ok my first post here guys, I sold my MTX terminator's i know haha really cheap 12's with a crappy amp but to me they honestly weren't that bad although i haven't heard anything other than that and kicker comps. i'm just now starting to learn about car audio. right now i have alpine cda-105 HU alpine type r coaxial 6x8s up front alpine type r coaxial 6x9s on the rear deck I was gonna get a 4ch amp and a mono block amp but i came across 5ch amps so u get your high's n mids and sub channel all in one amp the kicker zx700.5 looks like a pretty good deal and i'd probably come out cheaper getting that vs buying a 4ch and a mono block amp my question is would 70x4 be enough …

I have a 4 ohm sub so should i be looking for an amp that has the subs recommened rms at 4 ohms or how do i pick the right amp. i know thats not real clear but i couldnt figur out how else to word it.

Where can I get one and how much are they?

Sorry I ask so many question, lol I'm still learning ALLOT. I'm slowly piecing all of my equipment together and next on the list is a 4 channel amp. Want to keep it in the $100 range. Needs to power (2) 4" Coax, (2) 6 1/2" Coax. Looking for a clean 40-60 rms per channel.

Does anyone have any idea what the saz-3500d would put out watt wise at 1.33ohm while being fed 12v?

OK, so if I don't have it completely backwards, I understand that the higher the preout voltage, the lower the gain can/should be set because the amp doesn't have to be as sensitive of the incoming signal - so the amp can put out full power with the lower gain. My question is since the gain isn't set as high, is the amp drawing less current because of it? Or is it drawing the same amount of current as a signal with a lower preout voltage and higher gain setting? Just curious.

What is the importance of an amps efficancy? I know being effeciant in anything is good, but how does this affect amplifier performance when comparing apples to apples. If you have one amp that is say 90% effeciant at 4ohms and another amp that is 70% effeciant at 4ohms and are both rated to put out 500 watts at 4ohms at 12.8 volts; what does the effeciancy rating tell me, the consumer, about the amp I am using? Any input would be appreciated.

None on the lights inside truck work now and cd player wont turn on.. Should i run a wire from bat the the yellow wire as to get the cd player to work and.bb i think lights i just need new fuses correct?

So my kenwood kdc deck is acting up and I feel like I don't know where to start.. Ok so the other day my head unit would just randomly turn off and then back and on and back off again. It would work for the most part then yesterday I was stopped at the bank and it shut off and didn't come back on.. So tonight I re-did some of the wiring behind the head unit but still nothing. I'm thinking its either a bad ground or a loose wire somewhere.. It will come on for a good 5-10 seconds and then I move it and it shuts off. Any help is greatly appreciated.

I have 8guage kicker ofc wiring kit in my truck. Right now its powering one powerbass asa 400.2 subwoofer amp that puts 400 rms. I have an old amp that i want to put on my front door speakers that is 55x2 rms. Would my 8 guage wire be enough for that also? Or do i need to get another wiring kit to be safe? Thankyou. Oh and is there any advice for wiring my front doors? I want both amps in the back of thetruck. Do i run wires from where the factory wires are to the amp for high level input then another back to the doors? Or do i take the wire out of the door and then to the amp And to the doors? Thanks for any help.

i am thinking of putting in a computer for my car with a 6.5" LCD screen would i have to run the audio through the head unit ? and what would be the cheapest one ?

Just getting into car audio so be kind. I have 2 dvc rockford fosgate hx2 10's (500rms) Sealed 1.5cf box. I know these amps are overkill but eventually I will be upgrading my subs. Ive narrowed it down to 3 http://www.sonicelectronix.com/item_23550_Hifonics-Brutus-BRZ2400.1D.html on my local clist theres a used aq2200 for $300 Sundown Audio SAZ1500D V1s for $275 Id consider the crescendo 2000 but its on backorder.. I'll also be doing the big 3 upgrade. I can add a second alternator and battery if needed, but i dont 'think' ill need to get that serious yet. Right now im more concerned with sound quality (I listen to alot of rock) than I am with brute force. But i think…

Is trading a memphis mclass 1100x1 for a massive n4 2000rms plus $150 a good deal?

Hey people. I have a very simple question that i need answered. I have one hcca 15.2 and i have one hcca 25001 amp. I plan on buying another one of each to put in my car but just out of curiosity, both the 15.2 and the 25001 amp have been sitting up unused for quite some time, and i would like to know would that cause any malfunctioning in either of the two? Just curious, Thanks!

I tried to set the gains on some amps with a DMM and a test tone cd but I could not read the good values on the DMM. One of the Amps is an sax 1000 Sundown at 1 ohm : so I should read sqr(1000 x 1) = more than 30 volts. I don't remember the right number, but I had the good number when doing it. the maximum I read was 21.7 volts, withe knob to the max! What may be the problem? How can I do the good settings? The DMM is brand new, maybe it is a bad one. Hope not! So, I had to set it by ears. Help me, please!

Ok, so i get a call from my friend asking if i could fix his other friends mess up of trying to put in his H/U. I go over hoping he didnt do some of my earlier mistakes, which he did, he cut the factory harness trying to hardwire it...... i gave him 3 options: 1: try to rewire his factory harness which could be a while since its a GM 2: wire the H/U itself skipping the factory harness 3: trace each wire and figure them out, yet again skipping the harness and wiring everything to the back of the H/U We decided 2 would be the easiest solution *98 s10 ext.* and i was wondering if my plan was good and if he was going to lose any basic functions.... I'll wire the ground to a …

I´m not so god at english too start with cause im from Sweden! =) i´ve just bouht a saz-3500d and i´m wondering if i can load it down too 0.5ohm? At the moment im using it on 4 Audiotop 15.4 15" subs,and i had an Sundown 3000d before and the difference in preassure was really big and with the saz3000d i played 150.00 with music. But i´vw also bougt 2 Sundown nightshade 12" 2 * 2 subs and my otehr question is there any chance that i can play more than 150 db with the 2 Nightshade on the 3500d amp?

Hi, Im about to start a build in my 2003 Dodge Dakota, Will be running a Crescendo BC2000D to two 15" SSA ICONS and a Rockford T15004 to a set of Hertz HSK components and probably 2 8" or 10" Crescendo Mids. Have an XS Power D2700 so far just wondering if at this point getting A 250 amp Singer alternator or a second battery ex XP2000 or XP2500 would give me less voltage drop or if its even necessary with that power? All wiring is Knukonceptz Kolosses 1/0 Gauge 1 run - one run +. Also any advice on personal experience with people running Crescendo mids along with a high end component set? Thanks,

I thought about using the Batcap 8400 because it would save weight over conventional batteries. It weighs 70 lbs vs several hundred lbs for yellowtops. Its capable of 8400 amps @16V and up to 9600 amps@12V. Anyone have experience with these and how they compare to batteries? Any issues w/these things?

Hey so I was browsing woofersetc today and I came across this Clarion VZ400 Looks pretty nice for less than $400. I looked everywhere but I couldn't find a review. Anyone tried one of these or used a clarion head unit and know how they do? Looks like a steal to me so I'm just looking for second opinions.

i just put in a used alpine cda- something it has an ipod cord but i cant get it to work. On the very right side of the deck there is a power light under that a tittle button and a light that say ipod when you hook up the ipod that light should light up right and to use your i pod you pick ipod from the source menu right ? But the ipod light dont come on and there is no ipod on the source menu. any clue what my problem is think it's the deck or the cord? and i know its not the ipod because it works fine with everything els

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 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.

Hi guys, I'm transfering most of my gear from my old car to my new one. I had a 03 tdi with an Alpine HU ida-x305s with imprint module and now got an 12 tdi. I like the oem radio for all its features: hands free, sirius/xm, the iphone/ipod connection. I got myself an Audison Bit Ten D to tune in all my gear and got into an argument with a friend of mine about keeping the oem head unit. He says that the oem head unit is garbage and it doesnt matter how good a sound precessor is, if I feed it garbage in with the oem HU, it will give me garbage out to my speakers. I would like to have your opinions on this subject. Thanks.

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.
