Amplifiers / Head Units / Processors / Electrical

I have an old school Memphis amp putting 1500 at two ohms into two SA12s. Bass boost on the amp is 40hz, I have the bass boost up a quarter. Amp gain is at half right now but, BUT. I have a feeling it's not all the way up. I usually set my gains by playing Put On by Jeezy since it has a few different levels of bass and I can set it so it doesnt clip on any of those. I don't feel like im doing this right, so I need pointed in the right direction. I get a 40hz tone and put the bass boost to what? I just need help...

How does everyone like their sundown amps? I've always heard good things but would rather ask here where I'm sure many have them right now.

Aight I ran into a guy on Craigslist selling a earthquake ph2000w/d1 so I picked it up for 50 bucks anyone have any info couldn't find much on Google any help

I have a stupid question, but can you strap an AQ 2200 to an AQ 1200 and run 2 subs on it or would it put it wayyy out of phase or something

Driving my truck with the radio at an inaudible level. Subs just pop. Kinda like an amp with no soft on/off feature. Went to the back and looked at the voltage meter on my rear fuseblock by the 2nd batt. Reads 10.38v. And my subs have engine noise now. What happened? Its a 1991 ramcharger. 318, 220 A alt. And a red and yellow top.

I've seen several topics on this forum and other forums selling the Sundown 4500D for $900-1100 in just opened or unopened condition. Last I remember, they MSRPed for over $1800. I've been away from car audio for a while and I was wondering if there is a big scam out, or the 4500D just isn't what its crack up to be, or whats going on with that?

So recently I had to reset all of my settings in my HU (see sig). I'm now wondering. What is up with all the intense as hell stuff i can set. Idk what any of it does really. main point. This HU is seemingly more SQ oriented that I thought it was. Not a bad thing. It sounds great. But i'm wondering if their are any general tips to make anything else sound better. System notes: all stock speakers, just sub stage added. thanks, Brett

Audio Savings - Deal of the Day Nice little deal for a head unit!

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.

hey guyz.. having a little problem with my 4200 avh pioneer. I pulled it out doing some little maitnence and then when i put the wire plug to the back of the deck and started it it wouldnt turn on. I drive a 06 escalade and i have to use a wire harness with a interface on it. so what i did was make sure nothing grounded and re connected the power ground and constant yellow and still nothing. then when i unplugged the interface and plugged back in it turned on for about 5 seconds and then shut off again. Could this be a bad interface? or what could it be? please help. thanks

hey everyone, i am looking for a alternator for my 02' f150 5.4 v8. atleast 220amp output. i was at my local shop and he told me to check out power bastards alternators. i did and they have nothing but good reviews on them and there very good on price. my question is if anyone here has every used one before.. i really only have $325 to spend (and thats if and only if my alt. from my ranger ever sells..) i will have my AQ3500.1 running at 2 ohms (2600 watts) to a zcon 15 so i really only need around 2200 watts. i will have all 0 gauge wiring and as of now, no extra batteries. if anyone knows of a better deal on a alternator for the same amout of output or better. please lm…

I just picked up a Alpine MRD-M1000 mono block for $100 today and need help setting it up. I downloaded the manual offline but its not very help full. Its pushing 2 Earthquake DBX10 in a ported box. Each dbx is in a 1.75cu.ft tuned at 33 hertz. Some of the setting I did today are: input 2ch gain +6db LPF 80 hertz SUB 25 hertz I have been looking online for answers but having a hard time finding anything helpful. Any help would be great, thanks.

So something has gone wrong with my system and I am not sure exactly what it is... My setup is... -12" Icon -AQ 1200d; installed with 1/0 gauge wire and then 12 gauge for the speaker wire. -MY car is a 2000 Jetta VR6 and the alternator is stock.. it's either 90a or 120a but i'm not sure -I am using the AQ gain knob and I have a stinger volt meter.. I had everything installed at a local shop and it was VERY LOUD.. it was so loud that I was afraid to even push it for the little time it was working right, so I don't think any problems have been caused by listening to it too loud. About 6 days after it was installed I was driving around and I noticed on one song the bass was …

I would like to compare it against a new PPI class d 4 channel to see if all the time they spent on it produced results or just junk. I can't find squat for user reviews of the vlx4150

hey guys i have a couple questions regarding my mids/highs amplifier. i have a kicker zx 350.4 its the 06zx 350.4 model , this one http://www.sonicelectronix.com/item_6748_Kicker-ZX350.4.html#tabs i bought it used for $100. it was in excellent condition. only had it for a little over a month. this amp was a beast! my mids and highs were very loud when i first had this hooked up!! but now, my mids and highs seemed to have gotten quieter... my bass is still loud. to check, i unplugged my bass amp so i can just hear my mids and highs and experimented. id have to get to volume 45 on my headunit to make it sound like it did when it was at volume 28 when i first had the am…

i have a kenwood h.u. that ive had for about 2 years not sure the model name(can get if needed) but it has the 2 preouts in back and usb and aux in the front. I was playing my ipod yesterday and all of a sudden it just stopped , so i unplugged it and tried it again and all it says is reading . i have tried both my ipods and that is not the problem, the aux works fine . any suggestions on how or what i can do to fix it?

So I’m in the process of upgrading my cars electrical system, I’ve just done the big 3 and would now like to move on to the alternator. One problem thou, i know nothing about them or what kind i would need. Any info on them would be greatly appreciated. I have two amplifiers one a Kicker ZX350.4 and the other a Hifonics Brutus BRZ2400.1D all together they = about 300 amps, idk if this info will help but here it is lol

I am looking at these there.All three are around the same price. Going to be pushing a Dcon 10 in a sealed box.Seems like they all get some decent ratings.Not sure If would really need the power of the Brutus for the Dcon though. 1.Hifonics BRZ1200.1D 2.Alpine MRP-M650 3.Alpine MRP-M500

Alright iv ran into a bit of a problem. I have two amps one a Kicker ZX350.4 which accepts 8 AWG wire and the other a Hifonics Brutus BRZ2400.1D which accepts 1/0 AWG. Im runing 0 AWG wire from the battery to my trunk, i cant find a dist. block that will work with these wires. any ideas? Any help would be greatly appreciated.

Hey guys I'm upgrading my system and I'm buying a 12" Fi SSD. I have been researching amps but I'm not sure what to buy. I don't want to break the bank with this amp. What amp have would you guys recommend? By the way I need to be able to fit 0 gauge in it. Thanks in advance, Matt

http://www.parts-express.com/pe/pshowdetl.cfm?&Partnumber=263-683&scqty=10 Does anyone have experiance with these? And how secure are they? And is there anyone that makes buss bars on here. I think I remember someone a few years ago ofeering this service but I could be wrong.

Finally listened to you all and got a cheap charger at Walmart, 6A charge maintainer, microprocessor controlled, 72W 6amp fast charge 4A medium and 2amp slow 6V/12V automatic. Hooked it up and let it sit over night. In the AM the remote unlock didnt work so I knew it wasnt charged. Looked at the charger and it said full charge. I unplugged it and tried to start it, dead. Reconnected, put back to fast charge, it started...the fan revved higher and higher then shut off. I unplugged and reset, put on slow charge, fan stayed low reve so I left it for 2 hours. Came back, said full charge, but was dead. Gonna take the cheapie back today

Hey guyz, i heard 2 pops about 2 seconds apart then hit play on my iphone and silence. Ive had 2 different amps on my door speakers. ONe was an alpline mrp300.4 or something like that and now i have phoenix gold octane 9.0.1. both are 5 channel and i used only the 4 channels for my door speakers. I have pioneer 5800mp headunit, the pico fuse is blown so i catch a goodbit of alt whine and noise. which leads me to think that has something to do with the amps blowing? Could that have an effect on the amp if the fuse is blown? I checked all fuses and connections. It wasnt playin music when it happened either, which is weird to me. Please help me fix what im doing wro…

Is there really any advantage to running this amp on a sub. I know alot of sound quality guys love this amp to use on tweeters and mids. I was under the impression that once this amp pushes out a certain amount of watts it switches from class a mode to an a/b amp. The only advantage i see is that its stable down to .25 ohms. Anybody that knows about this amp please comment

Planet Audio AP3000D or Audiopipe 1800.1D? Specs on Planet Audio amp are higher than the Audiopipe. This is to push a 12" JL Audio w7. Any suggestions?
