Amplifiers / Head Units / Processors / Electrical

The local Circuit City is going out of business, they have all their car audio stuff marked down 40%. They've got a few Kicker ZX750.1 amps, originally $500..... and you math wizards have already figured out that they are now only $300. Rated at 750rms at 2 ohms, are they stable into a lower load? Like 1.6 (5 Dual 4ohm coil subs in series/parallel? 1.33 (3 4ohm subs in parallel)? Do they put out more than their rated power?

MTX re-Q, Fosgate's 3.sixty, JL's Cleansweep...there's a metric crap-ton of these Factory stereo processing units out there. Anybody got any experience with any of them? Are they even worth it?

sooooo heres how the story goes. i got an amp a while ago, the crunch gp 2500d, and then i bought some subs, like the aq sdc 2.5s, but take a little more power (called TF X's if anyone is interested) both dual 4's wired down to 1 ohm at the amp. anyways, i'm underpowering them by a few hundred watts, and i'm looking for a replacement. in my searching i as offered an earthquake ph-d3 for a bit less than 300 rom a friend of mine, but i think he used to use it for spl comps a few years ago. anyways, the amp works great, and at 1 ohm does 3000 rms, so i figure if i'm easy with the gain i'll get the output i need, or i can match my current output at 4 ohms with 1300 rms. m…

I am going to order two 12 inch zcon or xcon subwoofers & plan on ordering either the crescendo 3500 or 5500 has anybody experienced these amplifiers?

I posted a while back on my company's development of factory replacement radios - just want some follow up feedback from everyone. We made radios for Toyota, GM, Ford, Chrysler and have some more on the way including a Honda CRV and some universal fits. I've gotten some requests from customers and dealers. I'd like to know what other vehicles everyone thinks would be good to have. . . radios with the factory look and aftermarket features. What do you think and what have you heard? Got any questions or comments - please let me know.

Hey anyone sell a varible subsonic filter?

Would like to know what you guys prefer and why. The HU seems to have more precise control and you can change the slope as well. If using the HU crossovers, should the amp be set to full?

I'm looking to purchase 18 batteries for a build. Kinetik offered me an awesome deal that's hard to pass up. My problem is that I have heard bad things about these batteries. Do you guys think if I properly maintain them I would get better results from them vs the guys that had issues?

Ok, so i get a call from my friend asking if i could fix his other friends mess up of trying to put in his H/U. I go over hoping he didnt do some of my earlier mistakes, which he did, he cut the factory harness trying to hardwire it...... i gave him 3 options: 1: try to rewire his factory harness which could be a while since its a GM 2: wire the H/U itself skipping the factory harness 3: trace each wire and figure them out, yet again skipping the harness and wiring everything to the back of the H/U We decided 2 would be the easiest solution *98 s10 ext.* and i was wondering if my plan was good and if he was going to lose any basic functions.... I'll wire the ground to a …

Hey I've got 2 12" ssd's to a 08kickerzx2500.1 with a Kinetik hc1400 in the back. The first 4 weeks I had the setup it was great, working to what I had expected. Some said they have never heard any cars around here get so low. (tuned to 33hz) Then...last week I turn my PAC bass knob all the way up and then I hear the bass cut off, I then turn down the knob and it comes right back on. I turn it back up and after like 30secs it will cut off and on. After a few days it seemed to me as it was a battery problem, like when it was turned up loud the batteries could not charge fast enough so it cut off. I took it to auto zone and they checked both batteries and they said the k…

Do pretty much all head units send out a clipped signal at 3/4 volume? I remember reading something about 3/4 volume and never pushing the head unit to 100% volume... Also, if that's the case why don't manufacturers limit how much you can crank it (if possible?)

alright so im setting up a system for my cousin to get as a christmas present and the budget is $500, i have a Stereo and speakers picked out but they dont want to buy an amp so my question is will the stereo be able to power these speakers. the stereo is an Alpine CDA-105 and the speakers are the Alpine SPS-600c and SPS-600.

Hello forum folks. I have a 2004 Buick park avenue that I am wanting to install a system into. I have run into one problem...I was about to buy a standard wiring harness when I was told that I would need a "data harness" due to my car having onStar even though I dont use it. If anybody has had any experience in installing a head unit into 2000 and up GM with onstar your assistance would be greatly appreciated. If anybody could link me to the proper harness it would be appreciated as well...as I am trying to avoid paying a shop $700 to install my system. Thanks

well after a long and painful 8 months of design and thought----Pioneer P9 combo is what I have decided on. just letting you guys know----it shouldn't be too much long till I am dropping pics all over this forum of the install.

I was wondering if anyone knows what type of RCA's would work best for a Soundquebed 3500 amp? I was hearing about differential and coaxial type's is why. I know one type is twisted and the other is straight. Also,any brand inpatucliar would help.

what are some good high output alternators for a 2010 nissan altima. I dont want to do any electrical damage with an aq2200d and two bl 12's so i finally decided to buy a ho alternator around 300amps

Alright Everyone Its Been A While Since Ive Posted On Here. Im Saving Up For A Sundown Audio Amp And Basically What I Wanted To Know Is Has Anyone Ordered A Refurbished SAZ3000D Amp From db-r ? I know there reliable but can i trust refurbished stuff ? What Is It That You Do To a broken amp when you get it back? New Everything ? Thanks.

Wow it looks like nothing came up... So, i'm wanting to get a Sundown SAE-1000D to power my Fi Q10. My sub has dual 1ohm coils. My question is, what will i have to do to keep my amp from burning up if i wire it to .5ohms? If planning big three and a bigger battery. Any ideas? Thanks, Michael

I have 2 questions, and was hoping for some answers. 1. Do they make custom alternators, or just the ones listed on the site? 2. How do I contact them? (Is there an email, or do I just have to do it through their website?) Thanks guys

Who has the best deal on 1/0 wire? I'm looking to upgrade from 4 gauge to 1/0.

will the knukonceptz battery terminals work on XS batts?

Ok, I'm trying to do the big 3 on my buddy's full-size 1992 Bronco 5.8L Windsor, but I am absolutely stumped. The alternator doesn't have a post and plug like I'm used to. It only has two identical plugs. Any thoughts on how I can do the big 3? Where the (+) would go?

I recently purchased a old school zed made Autotek 220mxi. The guy sold it cheap as he had no clue on car audio worth. The amp powered up and worked well for about 3 hours of moderate use. It was powering 2 RE Audio SE-X 12D4s. I had it wired at 2 ohm stereo mode (2 ohm load each channel) which I thought the amp could handle. I ran a good 4 gauge power wire and ground (knukonceptz) with a 60AMP inline fuse and the gain was at maybe 40% max. Bass on stereo set at 0, loudness on low setting. After about 3 total hours of use spread out over 2 days it quit. When it died you could smell the "dead amp" smell of burnt electronics and it blew the inline fuse as well. Just for kic…

I installed a audiopipe 1500 to power a sundown x10 in a ported box. jl audio componants in the front doors jl coaxials in the rear deck running on a jl700/5 the 2012 mustang gt factory hu and lastly the pain in my back is a audiocontrol dq 61. I mounted everything on a wall behind the rear seats just in the trunk. I 2 separate stinger 1/0 for power as well as grounds. My signal is also stinger 9 conductor w/ 2 350amp fuses. the 5th channel on the 700/5 is waiting on jl8w3 mounted in the front doors. I hope there is something my eyes are not catching because the insides sound like tin cans. when I am able to improve the sound I cant turn them up beyond 25% without clip…
