Well, my friend installed a Rockford Type RF.4 4 channel amp into his car and after it was installed a popping noise would occur when he turned on his HU or when he turned his volume from 0 to 1. We must have regrounded that amp several times but the popping still occurs. We tried replacing the HU but to no avail, same problem occurs. I told him to try regrounding his HU but his HU was already grounded to a drilled, sanded spot. Right now, he is trying to shorten his ground wire. Now this only happened after he installed this amp. Before, I had let him borrow my trusty ol' Orion Xtreme 5004 and there were no probs with that amp so I'm assuming it has something to do with…

I am looking to get yet another alt for my car and I know iraggi makes good ones but has anyone used one made by excessiveamperage? I dont want to get ripped off like I have read few have.

I have an aq2200d that will be powering a ss rl-p 18 at 4 ohms. When i go to wire it up, do i use the outside pos and neg ports on the amp? Also, i have a kicker 200.4 for one set of components. I want to bridge the amp to make 100.2 at 4 ohms, but im confused when it comes to wiring it. there are two rows of inputs for speakers. one row says amp 1, and the other says amp 2. would i just do one speaker on one row, then the other on the second row? sorry its confusing. ill try and find a picture. http://www.sonicelectronix.com/pictures.php?id=11366

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. …

Friend asked me about the phase dial on his sundown 1500. I couldn't give him an answer. What exactly is it and what does it do?

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

I plan on running this wire http://www.wireandsupply.com/product_p/sgx-2-fslash-0-fslash-01.htm , which size of these http://shop.genuinedealz.com/Marine%20Electrical%20Supply/Tinned%20Copper%20Cable%20Lugs/00%20AWG%20Tinned%20Lug/?sck=12205831 connectors should I buy to run with the wire? Also will a 0 gauge distribution block work with that 2/0 gauge wire, I have not been able to find a bigger block? I will be running 250amp fuses throughout the setup. One from alt to battery, one 12" from battery to distribution block? I only want the cap to be used on the sub amp and both outputs on the block are 250amp fused, do I need to run anymore fuses in the setup?

I currently use a Lanzar Mxa252 2channel amp to run the dual 4ohm 15"l7 in a 1.5 cu ft. sealed enclosure. Looking for a amp to run the L7 1000rms@2ohm under $300 shipped, Soundstream Picasso PCX1500D for $287 on ebay or HIFONICS BRUTUS BXi1610D for $232 on ebay both are 1100@2ohm. Any other options would help.

We came across a Crunch 1500 watt Power Zone amplifier, P1500.1. it will power up and play music.......... as long as there is some pressure on one of the adjustment knobs..... Take away the pressure and the music output stops. The "Low Pass" filter knob is missing , once the amp is opened up, you see that the whole little box has been removed. so first question is ; can I purchase and install this box ? like is that i DIY type project? second question ; is there any home remedies for the pressure issue? anothere DIY project. If need be, I will send it in and get it fixed, but was hoping to do it cheap, in house. thanks for the input, chop IAK

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…

I ordered a 270 Amp alternator from Singer a little over a week ago, and he said it should be ready for shipment by the end of this week. I'm looking to upgrade my battery under the hood now, and in a few weeks throw another one in the back if needed. there's a ton of batteries to choose from...and from what I've read around on this forum you want a AGM/Deep Cycle batteries but if thats all your looking at there's a LOT of options. So my question is what specifications from batteries should you look at when related to car audio, right now I'm looking at a DieHard Platinum. What specs should I look at when comparing this battery to say, a Yellow Top Optima? Is t…

I am going to do the big 3 with 0ga possibly today or friday, ive been a lil busy. My current range money wise is prob highest for an amp is $500, my overall budget is around $1500 including wire and extra tools i dont have, my currnt money is about $890 towards the system, however i just got a better job so il have my money in about 2 weeks but …

Had my 4 channel amp sand blasted with sugar sand today, know i just need to decide on a new color. I'm leaning towards a blue to match the the gauge color of my 06 civic ex, but could could do it white and have LED tubes to high light it. Just not sure.

Hey all, I just picked up a Pioneer Premiere DEH-P880PRS off ebay for $200. Pretty good deal. The only thing is, is that it doesn't come with a cage, book, or harness. I get get the pdf of the book off of pioneers website. Does the 880 use a 16pin harness like all of the ones on ebay? There is a cage, harness, and trim panel on ebay for $15.00 shipped. So any help would be appreciated! -Ryan

Well let me first start off by saying, hello everyone! I know I don't frequent any of the forums very often anymore and I apologize deeply. <3's you all. Anyways, my dad came up to me the other day and had a car audio question! I was in complete shock and happy at the same time. It was great to hear him finally wanting something for the car my mom drives. And then it was a question about an in dash screen! Ok I know how forums go so please let me make this very clear and upfront. The two decks I'm about to have you guys compare are the ONLY OPTIONS available for debate. Please do not mention any other decks out there as in, "well this would be better." My dad…

I have had this system for over a year and it has been working fine until I got a short on the remote wire coming from my amp and going into the remote IN on the lc2i. It shut my system off, so I installed a new remote wire. once I installed the new remote wire my system worked again however I woke up the next day to find my battery was dead. It turns out I accidentally had a few strands of wire coming off of the lc2i's remote IN and touching the 12v port causing my amp to stay on all night. My issue is that when I properly install the wire into the remote IN port, It no longer turns my amp on. Could the remote IN port on the lc2i be bad or am I missing something else tha…

Hey Gents, i am new at car audio systems and would like to know how the BIG 3 is done. Can somebody explain this to me please. I got a response in a list form but didnt get it. Some help please? Also, does this help with dimming?

Let's say I'm running the Sundown 1000 watt amp with 2 gauge power/ground wire and an 80amp fuse near the battery powering a 12" Fi Q. If I want to change my sub to a 8" Soundsplinter RL-i, and replace the Sundown with a P.G. 400 Watt amp, does the 2 guage wire need to be changed? If not, then does the fuse need to be changed? BTW: I don't have those amps or subs. My main question was the wire question. I realize the Sundown would actually be good for a dual 4 ohm RLi-8. But let's forget all that.
