in the pinned topic, it says "Gain Setting Equation Voltage of the output = sqrt(RMS Power X impedance of the speaker)" i have a 2ohm DVC sub, so is my impedance 2ohms? or 4ohms? (2[dvc]*2ohms) or 1ohms because i'm putting it as a 1 ohm load onto my sub? the DVC is what throws me off here, the thread doesn't specify whether it matters or not. it also says to stick the positive and negative into the amp terminal... well my amp has 4 (2 of each polarity) terminals, should i use the negative from one set, adn the postive from the other? ex) A+ and B-? or ex) A+ and A-? thats my amp.

Does the SAZ-3000 accept a hifonics remote gain knob cord? If not then where can I get one? any place like Fry's or radio shack have them? or adapters?

I am capping it a ~$200, so a $220 would be an option but thats at the most. I am mostly considering the HC800, but was wondering if any of the Stinger batteries are better.

The other day I was driving and I smelt a wire heating up and starting to burn so I turned the music down and then my sub stopped working. I assumed my ground was bad but none of my wires are melted, my amp isn't in protect mode, no blown fuses and the sub wasn't blown. I can't seem to locate the location of wires burning and need some suggestions of things to do. I have 1 12" Q @ 1 ohm with 1000 watt Brutus amp powering it all.

Are the preamp sub outs on the head unit low frequency or full range then converted in the mono amp? Excuse my ignorance, I'm as "newbie" as it gets with this stuff. Basically, is there a difference in using them as opposed to line out on the 4-channel amp into the mono?

Hay guys, I was just wondering if anybody knows anybody that might or is selling two Incriminator Audio 20.1's? I live in Nashville, TN. I am willing to drive a few hours if needed. I am wanting to strap two of these on my one 18. I don't fell like paying there retail price, so I'm checking around first. Thanks for helping.

anyone have any opionions about there amps slowly designing a comp system and was looking at the two top amps from them i was also looking at the stetsom 7kd and the cadence zrs 9000d they are all around same power and i can get each at close to same cost if i find a better option i will look into that looking to spend around 1k or less

Can anyone recomend a good alt company. But it needs to be for older model cars. I'm looking for at least 200 amps. In a 83 buick riviera. Sorta on a budget.

has anyone ever used it and is it a good headunit?

Hi someone locally is selling a 300amp alternator for my car, which is a 2003 4.0L Explorer. I know the guy and he said he never used it because he just sold his explorer but he bought it from a place in cali. What should I be looking for to see if the alternator is legit? what tests can I do? Or should I just get a 240amp iraggi alternator? Any input would be greatly appreciated Thanks!!

Hey guys, I'm pretty new to the forum, I've been lurking for awhile trying to learn as much as I can. Anyways, I've had a 15" Memphis sub and a Memphis Power Reference P200.2 two channel amp for awhile. Lately my sub started to sound like it was fixing to go. I found someone selling two Memphis 12s in a box on Craigslist. I went and met the guy and hooked up the speakers, and they sounded good, so I paid the guy and started to get on my way. The speaker wires this guy had for the 12s were crimped and part of the metal was exposed. I went to push the box the rest of the way into my Explorer, and like an idiot, I let the exposed metal on the speaker wires make contact. Smok…

is it the same signal as the front rca output ... i do not listen to surround sound music or dvds so will the left rear sound exactly the same as the left front (same thing with the right side)? ... reason being i have 2 sets of components in the front and have my rears running off the high levels ... i wanted to run my front components using the front and rear rcas so i can adjust the kicks independently from the doors

does anyone own an old autotek amp and what do you think about them

when running multiple amps what is the best way to run (1) 0ga and (2) 4ga with only one run of 0ga from the battery under the hood. i am trying to avoid doing multiple runs (knu is 1.40 to 3.40 per ft.) or avoid using one of those cheap octagon looking blocks that has 6 different apps. i want to use anl fuses. 300 and (2) 100's. anyone run into this same problem and found something that worked better?

I just found out my car only puts out 105 amps max on its alternator with only 1 battery....will i be able to power my fi bl 18" sub, lights and air conditioning at the same time?????/The sub will be running 2 omhs -1200RMS

Well i got that JVC HU, it goes up to 34 or something when i turn it on 19 all the speakers start making cracking noise, including subwoofer. I know that this HU is piece of sh.... but what might it be ? Sometimes i can turn it up til 20 and its working fine.

hey guys another noob question! lol so what exactly is amp clipping and how do i tell if its happening? i just want to get some questions out the way well my stuff is in transit befor i begin the install

Would mounting my amp on the same side I mount my woofers cause any problems? I mean that would be the strongest part of the box considering its a double baffle? There's enough space to fit it there so I don't see how it would be a problem but figured I'd post to get input, any possible side affects?

what is a good headunit to run if i plan on using it as my crossover and 2 15's or 2 18's. probably orion hcca's or btl's. and a sundown audio 3000saz.

i just bought a set of boston pro60s for the mini. not sure if im gonna run rear fill yet or not...my question is...should i keep the factory HU and run a 3sixty.1 or jl cleansweep or one of those, and keep the factory HU, but with aftermarket speakers, subs, amps? or should i get an aftermarket HU? i want it to look some what factory, so if i get a HU, its prally gonna be the alpine 9855 becuase its black and you can change the color to amber i believe, so itll match all my dash lights better. anyone use the clean sweep? its like 119ish on ebay i think... pro's, con's? i never use cd's in the mini anymore either...i have a factory AUX input on the stock HU, and i use my …

I did the big 3 last weekend to my 2000 dodge dakota and was woundering about a wiring configuration. I currently have two 0 gaguge runs from the frame to the engine block and two 0 gauge runs from the battery neg. to the frame using the same post on the frame used in the frame to engine block runs. I have one run of 0 gauge from the alt. to the battery positive and a run of 4 gauge from the alt. to the fuse box which was place there by the guy installing the alt. Two Questions: 1) Should I run a 0 gauge from the engine to the battery negative, or should my currently setup be ok? 2) Should I remove the 4 gauge from the fuse box and run it directly to the pos. battery pos…

I'm installing an amp for my speakers and I'm just wanting to know what I should do for the crossover settings. I have 6.5" Alpine Type S components up front and 6.5" Alpine Type S coaxials in the back. What should I use for the input levels at the front (Full or HPF) and at the back (Full or HPF)? Lastly, what should the frequency be for the front and the back? I'm just going passive btw. Thanks in advance for any help!

Ok, I'm going to be running my wires soon, so I guess i need to start buying some. I'd like to use the Knukonceptz Karma SS speaker wire. I need to know what size I should be buying. I'm running 3 SAX-100.4D amps at 4ohms/4 channel so 100 overrated watts per channel. Sundown E8's for midbass, Tang Band 6.5 for mid and Seas Neo Tweets. Is the 16awg good enough or do I need to go up to 12awg? I know I'm not running tons of power, but I was wondering how much impedance loss I would be getting since the amps are in the trunk and the speakers up front. thanks.

what are your thoughts on these amp?
