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.

guess they have them in stock now..just fyi.. eDesigns nine.1 group buy on another forum.. $300 shipped is the group buy price, limit to first 20 orders..

Ok, I have never owned an amp w/o on-board fuses. I understand that fuses are necessary, but I am a bit confused about just how they are installed and WHY they are necessary. I'll probably purchase an amp kit that comes with an in-line fuse. I understand that this is to protect the battery in the event of...hell idk, I just know it's to keep shit from catching on fire. Now further down the line, the two amps I have have on-board fuses to protect themselves in the event that they should draw more current than they need/can handle. (Not quite sure about that either. I know that fuses usually pop when too much juice passes through them.) Now...I've been avoiding this by limi…

Gain Matching Correctly setting a sound system

hello i need amp wt these specs for my jbl gt 4 1000 watt 2 woofers please suggest me a good a amp 125W/2 ohms bridged mono (bridging into 4 ohms). Amp should have 4 channels each rated for 125W/2 ohms.

guys i need your help. i have a sundown sax-1200d powering 2 sa-12s. lately the amp has been making this high pitch noise as soon as i turn my car on, and after 20 minutes of playing it will go into protect mode and it gets pretty hot. is the amp screwed up or is it something else? any help would be greatly appreciated, thanks

I have an older Rockford Fosgate 500.2 unit and I had some questions about setting the gain. Everything I have read shows to take the RMS wattage X the ohm then get the square root of that. My only problem is since my amp is technically a 2 channel I am wondering how I do this with it in bridged mode. That wouldn't normally be an issue aside from the fact that this amp also has a left and a right gain control. Now the amp is 500 RMS x 1 at 4 ohm bridged OR 125 x 2 @4ohm stereo. How would I go about using a DMM to set these gains as close to perfect as possible?

Well, im looking into this amp casue its pretty cheap where i found it. I heard good and bad about it. I hear it will do 1/2ohm daily and over 3000watts? Are their amps any good? The model im looking at is the Concept CC-D2400, its an older model I think. Thaks for the help...

I am wanting to upgrade my system to 2000-3000 watts. I don't know to much about batteries and such and im not sure how many/what size batteries i would need to stay at about 14 volts. Also my truck puts out alt puts out 105 amps, Would i need a HO alt? Just trying to figure things out so i can figure out how much this is gunna cost me.

Sorry for sound like a retatard but what is Big 3?

I would like to give a big THANKS to johnecon2001, vladd and a few others for talking me into experiencing the wonderful world of Time Alignment. I recently purchased an Alpine 9887 and can not believe the difference in the imagining that TA makes. How did I ever get along without? Thanks again guys this is by far the coolest/greatest thing since Sliced Bread.

I'm thinking about going all out in my car. I'm already building a new box or two for my Fi BL15. I'm thinking 8"s in the front doors maybe some HLCD. Rear fill will more than likely be something modest. Now here is the kicker, I want to keep the factory radio. The car is a 2005 Chrysler 300c with the Boston Acoustics 8ch system. I was looking at the JL Clean Sweep, Rockford Fosgate 3Sixty, and I recently came across the JBL MS-8. The JBL website it awesome compared to the other two, but it appears the JBL is geared more for the person not wanting to add amps or aftermarket speakers. Has anyone used any of these products or something similar? There are no real sh…

Hey Friends... I just wanted to know how do you have your music hooked up? Are you running your wires from the battery or from the positive on the alternator? Right now I have 2 TC Sound 18' Ultra lLMS with a 200 amp alternator one red top batt one 1400 kinetik and 4 hc2000 kinetiks with one IA40.1 amp waiting on the other one. My plan is run two or three lines with the big three already done. I am trying to keep my volts up pass 13.5 when the bass hits. Please advise me on what to do. Do I need better batteries or 16v batteries. Do I need a Isolator or not when hooking up four or more batteries? I will be flying back to the states in two days and if some one could help m…

I am installing a Jensen MCD 6115, and two Jensen power 760 amps in my boat. The reciever has output of 200 watts ( 50 x 4 ). After I hook up amps through rca preamps at reciever does that reciever 200 watts transfer through the amp? or can I still use those reciever speaker leads for 50 x 4?

I was checking out this amp. I remember hearing nothing but good things about their stuff years ago, nothing recently. but I hadnt heard of SSA, sundown, Fi, or... either seen it usually for 260 and up, ikesound has it for 199. Ive seen ratings listed anywhere from 990-1150 watts RMS into 1 ohm. their website as a link to there amps but is loading a blank page for me right now, so I also cant find out if it has a SSF? they any good? put out true ratings? underrated?

is the power plant series any good or are they overrated?

Hey everyone I was just curious to see if anyone on here run's these amps or has had experience with them? I just installed mines today and it works like a champ, its used BTW but I was wondering if these pigs usually run on the hotter side? After about maybe 30 minutes of play time after hooking it up it was kinda hot, not hot where U couldnt touch it but not really warm either. So after about an hour and a half worth of playing its still working, it hasnt gone into thermal protection mode, But I was just curious if this is normal for this amp? But then again it is 2 amps in 1 chassis. LMK if anyone has input. thanks

the red got ripped out of the harness to my 4900 in my crash, where is the best place to get the replacement harness for this?

I ordered an Fi Q15 with BP Power option. Would a Sundown Audio SAE-1000D be a good match for this sub?

I was wondering when i need to upgrade the electrical in my 00' Jeep Grand Cherokee it has a 136 amp alternator. I have but not installed yet a 12" Fi SSD Sub w/copper coils being powered by an AQ 1200D amp at 2ohms. then i have CDT ES620 comps being powered by the AQ 4X90. Sub getting about 900 watts and the Comps getting 240 watts with gains turned down.

If one's amp would be clipping, resulting in a blown sub, is it a permanent issue? Or does the gain, bass eq, and other filters need to be tuned to insure that it won't happen with the new sub?

I went to reinstall my 1500d, but after only glancing at what side the power and ground are on I mixed them up. Ive heard the 1500d has internal fuses, but after seeing the protect light I took it out and didnt see any fuses on the inside. Am I out of luck and blew my amp? I tried switching the wires to the correct sides, but I dont get a light period that way.

hi guys i recently got 2 18 btls and 2 bxi 2610. now im looking for a ho alt for my opel astra. do you know a brand making a good alt for it?

I can not create a topic in section "For sale/Wantid" (No 25 Posts). I'm looking Clarion DXZ785USB. Delivery in Russia. Where agreement is reached 100% advance payment through PayPal. Please send offers with photos on my mail - [email protected].

I have a us acoustics usx2080 that i got from Audio Clinic off of ebay and it is hooked up to my pioneer premiere 720prs speakers and it just doesn't seem much louder than the radio straight to the speaker. My gain is at about 3/4 which seems kinda high to me but thats where the DMM put it. My HU is an Alpine 9885 and i used a 1000hz wave to set my gain to 17.9 volts. Someone told me it may be an install problem but what kind of install problem could cause this? Wouldn't it be either working or not working? Also, how much louder should this amp be than the HU? Thanks for any help or tips!!!
