I bought a KICKER 11VS12L72 ("that box has a dual 4 woofer wired down to a 2 ohm load. So you want an amp that is 2 Ohm stable") And I'm trying to find recommendations from the experts for an amp. I am leaning towards the SoundStream DTR1.1700D that is on a sale for $188 online. Might buy it tonight if I don't find anything better.

Just came across Alpine's new CDE-HD149BT HU and was wondering what others think of their latest and greatest. The new twist is that you can tune it via a smartphone app. Supposedly you can tweak time correction and crossover frequencies, plus a 9 band parametric EQ. The app also lets you share your tuning settings via facebook and apparently lets you save tons of settings and makes tuning easier...hype? I am looking for an active capable hu but haven't fell in love with anything yet. Hear nothing but good things about Alpine but can't find one that seems to open my wallet. I really liked this when I first saw it but the more I think of it the more it seems a little hok…

ive got a Diablo Audio Hellfire 8000.1 it has a blown power supply. where can i get it repaired? Db-r does not do them, already checked. i know of amp medics, any others? and what happened to them? their website is gone, and i cant find them anywhere.

i know alot of people on here run a 3400 in the front and a 3100 in the back. im in a honda so standard size is a 51r. i wanna get an xs for the front (for now anyways) and i like to think ahead. is there a big difference between the 51 and the 3400. id have to do some customizing to get the 3400 to fit but id rather not if i dont have too. if i run a 51 in the front and a 3400/3100 in the back eventualy is the back one gunna drain the front? im probably only gonna have 2-2.5k and might soon be upgrading to a 190A alt

i just heard something weird from a tech at Hifonics. the reason i am not getting sound is because i have "stereo input RCAs" or something of that nature not "mono" ones... so now i have to buy a splitter that will connect to one of my old RCA cables that will be split in to two for the two inputs on the amp... if that makes any sense.... i find this weird because on my old RF amp it has matching colors for each of my old RCA cables which made it so i didnt need to buy a splitter... is this normal? i thought it would be straight forward red to white but i guessed wrong...or so i hope!

How much of a difference between Stinger and Sound Quests line of pure oxygen free copper power wire. Is it pretty much the same with a different package.

Currently i have a some JBL components (608C's) in my truck but, but i am currently thinking about purchasing a RF 3sixty.3. My main question is since i am already using components does it even make since to make the purchase unless i change my front stage speakers? I know it is kind of a vague question with many different variables but to keep in context if you are currently using a passive cross-over would going active give you any benefits as far as sound quality?

Does anybody have any experience with the above HU, just want to know if it is any good in general. Mainly going to be using my ipod.

Sorry, the topic may be a little vague. I've recently found myself researching amplifiers as I may be replacing my zapco c2k 9.0xd amp shortly. I have 2 12" dvc subs with 1ohm per coil, and they handle 1800wRMS/ea. they're situated in a 4.2cu/ft box tuned to 30hz. The zapco puts out around 2200wRMS and I was looking for something a little closer to the subs rated input or over. So I've been working on a spreadsheet to compare different amps to try and discern a value. This task has been pretty difficult, most of the amps I'm looking at seem to be extremely similar or clones of one another? My understanding is that an "OEM" would reach out with a chinese or korean manufac…

Im looking for a good reliable amp with will do at least 1500 RMS at 1 ohm at 12v and be as efficiant as possible. No more than 2000 RMS at 1 ohm. I have my mind set on a RF T1500.1BD but Im open to new ideas.

So my jeep has a stock 160a alternator. I plan on upgrading to about 2k rms here in the next few weeks. I was wondering if that alternator would cut it if i did big3 and got some extra batts. What do you guys think?

I'm about at the point where I need some electrical upgrades, my car is an 04 Mustang, electrical is stock no big 3, has a Optima Yellowtop My amps Bass amp has 160 amps worth of Fuses, Treble amp has 60 amps worth of fuses. If i play songs with real long bass notes my treble cuts out, maybe its just my sh!!TY wal- mart sony amp, i have a brand new soundstream amp that I'm going to have put in here shortly. Anyway can I put a 2nd battery on the stock alt. or should i go with a 160 amp alt or a 200 amp alt or what?

I am figuring on buying 2 15" Q. I am debating whether i should get the 1500zx kicker amp or the PA 4000 amp. I also need to know whether i will need a new alternator if i already have an upgraded battery and a 4.0 FARAD capacitor. I want the system to be loud, and not have to worry about blowing the speaker. Also should i get the 2 15"s 1 ohm or 2ohm if im going to be using one amp. Thanks

which draws more current...both would be run @ 1 ohm can the orion take .5 daily or does it need modding? its for the 12mt in the mini...i have no room for an extra battery either, nor do i want that much more weigh if i did have the room.

so, im borrowing her mustang for a week, and shes using mine but shes got a few problems i wanna check to make sure before i do anything. 1. after about 2 hours, it all cuts off... im thinking cuz her amp gets too hot. its a dual 600w amp i think, and its powering the inside speakers, and her 10" xplod. should i rewire the inside speakers to her head unit? only bad thing is its a 4 channel amp i think. so, how would i get that working with just 1 10" sub? or should i leave that alone? 2. hermusic lately has just been cutting off for now reason. i THINK the fuse on the power wire from the amp is loose cuz when you wiggle it around the fuse, it works again. mabe i should r…

so is a second stock alt going to be as good as an ho alt?? the town i live in has an auto program at college that i can get a alt from a junk yard for $$22.00 and they well clean up and run through it for me, (im waiting on a call back from them to se if they can recoil it as well) and they have a fabricating shop that for the price of materials well make a mounting bracket also i know that there are alot of car audio specific companys that make batteries, but would 1 everlast maxx 1N under hood(replace stock) and 4 in back(total 5) be just as good as 3 audio batteries? i can get the ELmaxx1N's for 89.99 apeice so like 450.00 for 5 batts?? just woundering

he sent it cause he knows I am a old RF amp nut, but here is the .pdf link >> http://www.rockfordfosgate.com/press/asset...25punchamps.pdf

Hello everyone. There have been numerous times where my voltage drops to 11.7. I usually have a constant 12.8, or 12.9 (never 13 ) On idle with music a little bit up (volume knob at around 20 out of 30) and/or other electronics in car I'm around 12.5 but when I'm at idle and my music is up it can get to 11.7-11.8 I have a 96 civic. Stock alt is 70amps. I have a kinetik 800 under hood and big three done with 1/0 kicker wires. Those are currently the only electrical upgrades I have. I have a temporary system in while I'm saving up for some good stuff. Just a 12" Sony xplod on a 250w monoblock xplod amp. My voltage drops from this? Gain is 1/4 up I'm not een stressin th…

I was going to get the alpine 9886, but I came across the amazing deal for boxing day, Amazing Deal on HU Has anyone had any experience from this particular HU? I havent come across 1 negative review on any site, other than Pioneer's grounding issue, im not to worried about that.

Okay, my buddy just received his fi bl 18's. he has 2 of them running off an audiopipe 3000. They are both D1 ohm. Would i wire them in a series for them to be running @ 1 ohm from the amp or would i wire them parallel. AND after i figure that out how would i wire them in series and how would i wire them in parallel.

I have always seen to use a 50-60hz sine wave note when setting gains with a DMM. And this is what I did, I downloaded a 50hz and 45hz note from realmofexcursion.com and went to set my gains. The number I was aiming for was 34 volts, and I did it first with the 50hz, and reached 34 volts. But then, out of curiosity I played the 45hz tone and the output voltage went way up. Like around 45 volts. I was not expecting this jump. I always thought the voltage would be higher in the 50-60hz range?

This may be a stupid question but this amp is a month old and i noticed the other day when i hooked up my new sa-10s that i had music coming through my subs. My lpf was at 120ish so i dialed it back to 80. Should there be music coming through at 120? especially on a mono amp? IM worried somthing is wrong with the amp as i have never noticed that before on my other amp which is exactly the same only from different vendor.

hello guys, just wanted to ask if there is a benefit of changing from a 701 to a bitone? would we get a significant gain in SQ for doing such? assuming that all we need is letsay on the 701 already... thanks.

anyone know the deal on the new Punch amps, other than boring heat sink and more power?
