Hey guys. I just got a Rockford T2000 today and I am a little confused. The birth sheet says it puts out more power at 2 ohms than it does at 1 ohm. Whats up with that? Here are some pictures of it.

I have a crossover/eq and a petra full range crossover.I have to much midrange and has to much mid in the speakers.Can i use my eq to controll my mids.

I have a 2008 Silverado Single Cab and am getting a Single 10" SSA Icon and would like to buy a Planet Audio RXD1400 to push it at 2 Ohms. It will be giving it 1000Watts at 2 Ohms. Will stock electrical be sufficient? I also have 4 Gauge wiring which isn't to long due to truck being a single cab. What gauge wire should I use for speaker inputs?

Hey guy's. Just doing some research and was wondering if the deka was comparable in power to the xs? I can get the deka for 225 and the xs for 290. The price difference is great but is the quality and power there aswell? Thanks Matt Cusack

Ok, I hear a lot of people saying that it is a good thing to run HO alts. and deep cycles together. I have also heard that it is a big no-no because a HO alt. will charge it quickly and they are supposed to be charged slowly...hence shortening the life of your deep cycle. Anyone have some input??

I know how to set the gains with a DMM by reading the sticky post by im confused on 2 things 1)when setting a 4 channel amp with 2 gains(1 for each 2 channels)how do you get each gain?my amp puts out 75w x 4(@ 4ohm) 2)When it said if ur amp puts out more watts than ur subs can handle use the watts of the subs instead.so lets just say a amp is 1500w @ 2ohm and the subs is 600w each so do i add the watts of the subs and find the square root of them then measure the volts?(For example 600w x 2ohm =1200-squarerooted = 34.6v)

i'm running one mtx 8100d to one fi bl 18. i have a second 8100d and was thinking about using a maxxlink to strap them but not sure if it will kill the sub. my second thought was to sell both amps and get a saz-1500. the more i read about them the more i'm leaning towards going with sundown. so anyway is the epic-160 worth getting?

No, they are not mine - just saw them, would LOVE to get them, but I don't have a spare 8G's to drop. http://cgi.ebay.com/U-S-Amps_W0QQitemZ3203...%3A1|240%3A1318

So after getting another battery that i had layin around and my trusty 250a battery charger, i hook the battery up backwards because someone decided they'd have a black wire for + ...lmao scared me a lil bit as sparks flew everywhere... Ok but i get it hooked up and it still cuts off as the charger has 12low, med, and high. High usually runs my voltage up to 16 and into dangerous levels, so i turn it up and then go turn the battery charger to high, and voila. I had the gain turned all the way down and my trunk was about to kome off. I'm not really quite sure if the SX's can take it,lol. I let it play for about 10mins, the cones were extremely hot, so i gave it a break. …

hello, is it possible to blow an amp with a volt. drop from 17.9-13.sumthing?? a friend of mine has a mojo 4k and he only did three burps with it and that was his volt drop is it possible to blow it like that??

so i've seen videos and people have a little digital volt reader on there dash, it reads how many volts the battery (or alt?) is putting out, and it has blue numbers... where can i find one online and what are they called exactly. also, i can't exactly afford 1/0 gauge power wire set from street wires, which is who i want. and i can't wait any longer to get my system put in my new car. i have a SAE 1000D amp with a 12" Fi Q going into a 2001 grand cherokee. stock alt is 100amps. anyways, i used the 4 gauge in my previous car, even though it's rated for 600w, thats what people on here told me to use. i wanna upgrade my system to a BTL or Xcon, i haven't decided yet, but i …

I was just wondering if 4 of these batteries will be good for a car audio system. 2,000 watts RMS? This is the only best battery that I can fine in my own town. I can't get XS Power or anything like that. They do sell Kinetik at this one place but they are marked up 50% higher then SonicElectronix & I don't want to mail order any car batteries. There Shuriken batteries at another store too. there marked up high like the Kinetik. I like to buy them in store, If anything gose wrong with them. I can just drive to the store & return it. These Nautilus AGM Deep Cycle batteries are in stock ready to buy. Motomaster Nautilus AGM Deep Cycle 12 volt Battery C$259.99 Brand …

Is there a way that i can test voltage drop with a digital multimeter

Ok, so I have a yellow top group 34 up front right now in my suv. I am upgrading my stereo system and will be running a Sundown Saz 3000d a JL audio 500/5 and a JL e4300. I will be using a mechman 275 amp alt and I need help deciding what to do for the batteries. Can I hook up the optima to a xs power d3100 and expect to see good results? or a d3400 up front to a xs power d3100 in the back. Is it alright to hook up batteries that are of different classes? I can't fit a 31 series up front but it looks like a good battery for the back. Last but not least I have seen good deals on a optima yellow top d31t. Would that be a good option to hook up to the optima I have now? Woul…

So i got a double din installed on my car and after about a month my system would just randomly turn off(headunit would power off and same with subs and amp) it did it once then would reboot. I took it in they changed the wire harness and the ground. It fixed it for about 2 days i then decided to change my negative battery cable and that fixed it for a few months and then it came back and i noticed that with the head unit turned off that there was a bass note from the subs playing real faint until i turn the bass knob it gets louder. What could be the issue on why my head unit turns off by its self faulty head unit, bad amp need help asap.

i'm getting a subs for it and i'm getting 2 rlp12" subs and i was looking into getting a lanzar max pro 2400 watt amp or should i look into getting a differnt one if not whats a good amp will the speakers handle a 2400 amp could they handle a 4000 what amp i dont know much about this stuff so i need help and sealed or ported box i got plenty of money

So lets say I have the potential to draw 700amps with my system, If I have 1 battery under the hood and 3 more in the trunk, a run of 3/0AWG wire front to back, how do I fuse it? Last time I checked the largest ANL fuse was 300AMP How do you guys with monster systems do it? other than multiple runs of power wire.

My question has to do with the bypass. If I were to bypass by grounding the parking brake sensor will my rear view camera work? If so which wire am I supposed to splice on to under the dash? I do not need the color wire although that would be helpful but which wire am I supposed to be looking for?

I just hooked up my equalizer and i taped into the head unit ground and power wire to power the eq and when i start my car i hear the engine noise ? how do i stop this?

Who wanted to donate a "few" pennies to me to buy that new hi fonix amp :ph34r:

Due to my battery hookup location and the fact that it will be nearly impossible to get a 0 gauge wire on it unless I rewire the alternator and main power line toa new battery block, how bad would it be to run 4 gauge wire to a fuse block and 0 gauge afterwards? According to charts 4 gauge should be able to handle up to 300 Amos if it is a short length. So will battery —> fuse (4 gauge 1 ft long) —> distribution block (0 gauge guessing 13 ft long). Will this work ok?

Checked under the hood today and saw this... So pissed. Looks like I won't have my truck for a day or two. Getting it towed to the dealership tomorrow. Hopefully they don't try to screw me, as they installed it in the first place...Wondering what's preventing it from happening again too... :suicide-santa: :suicide-santa:

Im looking at this crescendo BC2000D for my fully loaded BL 15 dual 2. Want to run it at 1 ohm . I rather buy a amp that has a little more to give, for if i upgrade from the BL to a different line down the road. Also the price isn't bad. Good choice or no ?

All my previous amps have had a ssf with a 24db slope I have set 1/2 octave below tuning. My new amp has 12db slope and is 2000 watts more power than my old amp . My tuning is at 33hz on two sundown U10 putting 2500 to each sub so would best bet be to set the ssf at the tuning?
