im in the market for a new amp and im doing some research on different brands. and i want to know what you guys think and also know which brands are more efficient and have cleaner bass?? also what was the formula to determine amp efficiency??

do you think the US AMPS xt4000d is a good amp for a fully loaded 1 ohm 18 FI bl?

So, we did a rewire, and the Pioneer has been sitting for a little while. Went to test speakers and the h/u wouldnt power up, except the amps were turning on, h/u was getting power though. Fuse looked fine.

after buying these batteries i found out that they are 34M's and are "starting only". now does this matter? the MCA is 1000, CCA 800, AH 50, RC 100. Did i get ripped? (only paid 100 each) or are they good?

Would I need a H/O alternator or another battery to run an AQ2200D? The stock one is 150amp and im looking to either run an HDC3 18" or FI BTL 15" in an 02 Trailblazer.

Ok I ran 0 gauge wiring for my saz-2500. I put a 250 amp inline fuse and as soon as I connected the negative terminal the inline fuse blew. So I pulled out the wiring to make sure it wasnt cut went it went through the firewall and disconnected the amp. Ran the wire outside the car without the amp connected and the fuse didn't blow. Connected the amp and the fuse blew once I connected the neg terminal. Faulty amp or am I missing something? Amp was a refurbished purchased from db-r.com. Any ideas I'd appreciate it.

Anyone know if the CCD-2400's are strappable? I just ordreed a pair of them and am trying to find out and Concept's Tech support has been less than fabulous. Trieid for over a week to get them to answer and email with a few questions with no response. I have called them half a dozen times with no answer at the Tech support line. So I have left some messages with no response. Is it possible they have just one tech guy and he is on vacation? I hope this is not a sign of things to come from them.

Plan on using the Hifonics, rated at 750w rms for my SSD 12" coming in soon but I was thinking about a JL 500/1 which is a class D versus A/B on the Hifonics. Is $150 a good deal for a used JL 500/1? I would think the JL offers a clean 500w and I've read the Hifonics are overrated. Which one would you guys go for? Thanks! Sunny

Ever sinced I changed my stock battery to a XS D1200, after a few days of the initial installation, been noticing the car is starting to take a hair longer to start... While working on the car today, i noticed right after i got done driving it.. it was reading 12.6v.. that's pretty low from just turning the car off. So i clamped the battery cable, reading 0.4A draw... hmmm... Pulling fuses under the hood and came up with this- AM2 fuse - (according to forums, controls Starter, fuel injectors, etc....) this fuse is pulling 0.15A DCC fuse - I do not know what this is but it is said dealers pull this fuse to prevent battery discharge if car is left unnattended for days. Thi…

last night i picked up a "Massive Audio" 3000.1 took pics but forgot the camera @ home today, will post pics tonight http://www.massiveaudio.com/broadband/prod.../pro/p3000.html

Hi im looking to buy two Fi 12" SSD's and want to hook them up to only one amp, is it possible to wire them at 1 OHM?

Since a week or two, my Pioneer head unit has some problems. Sometimes the "face" doesn't respond, as if there is no power to it. It can happen with the music playing or with the h u off. If I unplug and the plug in the car fuse for the h u, eveything starts working again. If I press the reset button on the h u it starts working again, but I loose some settings. Do you know (or understand) what is happening ? Can it be a simple fix, or will I need to buy another h u ? Please help !!!

I have a 1999 Buick Park Avenue and am getting ready to purchase the things that I am still missing in my setup. My main concern is my Audiobahn 2300hct powering my 2 12" JL W7's at 1ohm. I have a yellow top for the trunk and a capacitor as well, here is where I'm lost as I've never used an extra battery or a cap before. The AB has 4x40 fuses, and I also plan to buy a 4 channel amp that does 75x4 rms {not sure on model yet}. My first question is how many fuses should I run throughout setup? Currently I have a 200amp ANL fuse, should I run this 18" from the battery {front duralast, or trunk yellow top}, or should I run a 200amp ANL at each battery? I Also plan on purchasi…

Ok. Ever since I can remember I have had a small problem with dimming headlights. However, I never really noticed because I don't blast my system full tilt very often and hardly ever at night. For some reason my lights seem to be dimming a lot lately. I currently have a 200amp alternator with 3 deka intimadator batteries. This powers my saz3000d at 1ohm. I thought that I might have a loose connection or my alternator was failing. I started testing voltage and this is where I'm confused. With the bass at nearly full tilt with the lights dimming bad my voltage stays at a steady 13.98 volts. With nothing on it's charges at 14.2. So, my question is how or why is my lights dim…

I,m looking at the saz 1500 or 2000 . but my cousin say s i would need electrical up grades with the 2000 and not the 1500. on another forum i read even the 1500 needs electrical upgrades. is this true and if so would it be major? Also i want to run one deep and loud 15 ported , I like hdc3 but aluminum coils need too much power. any other suggestions?

I just got a Denon DCT A100 and it didn't come with a manual or anything. I went to put it in and i saw that it has a few extra wires that I don't know what to do with. They are labeled as light, acc, aux in, and p. ant. What do these need to be connected to? Also, will I be able to use the same dash kit that I used with my old Pioneer HU?

Well, my friend has recently been having issues with his electrical system. He currently has a red top and yellow top in the back. He reads around 14 volts up front but his battery in the rear (not isolated) reads at 12.5 volts?! The battery in the front and rear both read at 12.5 with car off. Any clue what could be causing this issue?

i know the 200.1 is the same as alot of 3000s out there. but Bob is claiming its 3700w lol and the new 150.1 does 3300w? last i remember the 150.1 was no louder than a mojo 2000 or crossfire..

installing my new system and my buddy says no dont run fuses.this is what im running 4 runs of 0 gauge wire from the front battery 2 power 2 ground,in the back i have 2 kinetik 3800s and a 300 amp altenator but the alt wire is fused.there is currently no fuses on the power wires for the truck but have not finished yet so just wondering what everyones opion is.im thinking 2 under the hood one on each power 2 before the batterys in the back and 2 after the batterys in the back.thanks

I just had the 5030 installed in my girlfriends car and I need advice from someone that has experience with this deck on the settings. I have 6 1/2s in the front and back running off the deck and a 750 watt Kicker amp powering a sealed Icon 15.

would it be possibile to run my jl 500/1 to 4 coponents and a set of tweeters. i would have to turn down the gains ,but would it be a good or a bad idea to even try somthing like that.

I currently have a Pioneer DEH-7800MP and am very happy with it except for the fact that I would like a DVD player/flip screen. I'm trying to find something with 3 preouts, some crossover abilities, and fairly inexpensive. The head unit has to be single din and a flip screen because my dash would have be cut for a full din. The Clarion looks decent but I can't find much info on it other than really general stuff. Ebay, Crutchfield, and other online sites have it for around $350 shipped and that's the price range I'm looking for. I'm not sure if I will be happy with less crossover abilities but not sure if I really need them either. My current 4 channel is a JL 300/4 runni…

I was looking at the Alpine PDX 2.150 to run the Clarus 61-2 comps. I talked with Scott and he says that the PDX is not a really good SQ amp. He did mention the new JL HD amps. I'm looking for a amp like these that are small, don't get hot because it will be located in the cargo compartment in my Trailblazer.

Hey guys, Been a while, but it is warm again. I am going to a friends, and he is putting 6 cheap components in the back of his car temp. He has 1 amp which is a 2 channel amp. Should I do 3 a piece or should I bridge the amp? Should I do 6 off of it? Thanks Josh

Here's the deal, in my previous few installs, I had been using a simple 12$ RCA bass control knob. You run RCA's from the HU to the knob, then from the knob back to the amplifier controlling the input level from the head unit to the amp. Simple. Well I recently got a new amp, which came with a Remote bass control knob. I hooked this knob up to the amp via the telephone jack looking remote cable, while still running my RCA's through the original knob. I've been keeping the RCA knob at 100% and using the remote to control the levels.. My question is, is this a bad idea for any reason at all? Perhaps output voltage from the RCA's or something of that nature? Also, what are t…
