i have two fi ssd 15's running at 600rms each on a pheonix gold 1200.1 and it just isnt pounding enough for me i wanted to give the fi's a little more so i was looking for a new amp. i wanted to give them anywhere from 800-1000 each. i came across an amazing deal and got a brand new opti4000d which retails for about $900-1200 and i got it for $300. i just couldnt pass it up.. i know there are mixed opinions on the opti's but for the most part i hear they are decent. now heres the question.. 3000 watts at 2 ohms is too much to give to my ssd's. what do you think i should do? im totally down for new subs.. or i can sell the opti and make like $500 for a new amp. i love the…

My voltage is dropping down to 12.4 at high volume this is off an 180 amp alt with three battery in the back (kinetik 2@2400 & 1@1400). The 12.4 is at the amp and my voltage at the front battery drops to about 12.9 & 13. Would i gain any dbs if i upgrade to a bigger alt? I have been thinking about upgrading for awhile now just wanting to know if I'll see any diffference to justifly the upgrade. I am running an audioque 3500d (the old one) @ 1 ohm.

As the title states im looking for a new digital multimeter for a few reasons. I was looking on amazon and i see they have them ranging anywhere from $5 all the way to $200. I dont really know the difference one would have over another but im willing to spend anywhere from $10-$25 as its just for a few purposes here and there. If anyone has any options on a good decent DMM feel free to post them here as it may also help people in the future to decide which ones to get. Thanks in advance

Does anyone know of where i could send my amp to get fixed and or beefed up a little bit? just curious. i burn a cap in my 3k and i was looking to maybe send it out and get that fixed but also beef it up and have them make it one Ohm stable. Its an Audiopipe Ap 3000.1d.

KnuKonceptz has a 1/0 CCA amp kit for 60$. Their 4 gauge OFC kit is 52$. I know pure copper is better than clad, but is 1/0 clad better than 4 gauge pure copper?

I am not going to be ready to buy for about 6 more months. I just don't have the expertise as to brands and availability for my particular application. I would like to see 140amps. Any direction is much appreciated. Thanks, Chris

I have a pretty basic question. I am looking to upgrade the amps I have to Sundown amps. I need to know if the current wiring will be enough and if not what I need to upgrade. I am having a authorized dealer install these so I just need to know what I need to tell them.

Haven't been here in a while guys Just wanted to know the advantages and disadvantages of running amplifiers at different loads. Nothing specific, in terms of amplifier brand, but just general advantages and disadvantages. Thanks.

I have a AQ2200.1D amp at 1 ohm with my 12" ascendant mayhem, it pounds off stock battery bit I hit the clipping light at around 20 on my alpine cde-hd137bt. I do have a 270 amp HO alt and big three and my lights dim sometimes but I'm wondering what all batteries do I all need to make it bump harder, louder and deeper, and make my stiff rear view mirror fall off?

I have ordered 2 Fi BL 12's Dual 2 ohm coils, with the Pchamfer, Flatwind, and daily option. The box is being built this week. I'm deciding on an amp to power them. Currently I have a Kenwood 9152D (supposed to be 900 RMS @ 2 ohms and 900 RMS @ 1 Ohm) So I thought perhaps getting another 9152 and strapping them together but that would under power the subs cause I know i'm not hitting 14.4 volts The 3 amps I've narrowed my interest to are Kicker ZX2500.1 (2500 RMS @ 2 ohms) supposed to be underrated MTX TA92001 (2000 RMS @ 2 ohms, 3000 RMS @ 1 ohm) dunno if this one is underrated? SSA 3000D (1600 RMS @ 2 ohms, 3000 RMS @ 1 ohm The Kicker gives me the perfect amount of powe…

Alright here's my Dilemma, I have two head units an Alpine IdA-x200 and a Kenwood Excelon kdc-x589. I'm trying to determine which one is better. They both have their pros and cons starting with the Alpine. pros: Ipod support, good looking, ease of use, and usb support. Cons: 2v pre-outs, and for the kenwood Pros: 4 volt preouts, sounds great cd support, 2.5mm jack in. cons: no ipod support. I'm trying to determine which one to keep and give the other one to my father. Also i was told by a local shop owner who competed in world finals said that typically CDs tend to get louder than MP3's is this true? here's some more specs. Alpine: # digital media receiver (no built-in…

My 97 EB expedition has 4 gauge wire comming to and from the battery. Double that on the power. I am going to replace the ground wire on the bat with 1/0, but the power side is all so beefy I'm not really sure I need to. My deck has a volt meter built in, and I have been playing with it, and wanted to know if you guys think I may need to upgrade the electrical. I have not installed any amps yet and really just want to get a feel for if you think anything else should be upgraded. When idle I sit at about 13.8 V. I don't know how much drop I should expect, but if I open and close all 4 windows at the same time I drop a few tenths of a volt. When I turn on the lights …

Well, the time has finally come for me to try out an active front stage. This will be my first attempt at this and I don't know much about it. I think what I want to do is run an active capable head unit and a nice 4 channel like the IA 6.4 going to some 8" pa mids and super tweeters. I only plan to run 2 mids and 2 tweets for the front stage. I'm looking for something to keep up with at least two 18s, maybe four 18s by next year. Any suggestions on head units, mids and tweeters are welcome and appreciated. So far, I've been thinking about Ciare PT 382 super tweeters and either the Ciare 8.50NdW 8" mids or the B&C 8 NDL51 8" mids. Please, let me know what you think of…
