Amplifiers / Head Units / Processors / Electrical

I see a lot of stuff being sold used on forums and ebay. Is there any general rule to follow on how much they should be worth compared to new? Anything to watch out for as far as life span?( Would you buy one 10 years old) Which go the distance?

Anyone know anything about these old series 1 amps? Rockford Fosgate 4 channel amp, Series 1 4060x with high and low crossovers - $50 shipped (4x30wrms@4ohms, 4x60wrms@2ohms, 2x180wrms@4ohms) I'm not sure that such an old amp has the best crossovers for SQ purposes but just wanted to see if anyone had any experience with em and whether pricewize was even worth it.

I bought a Pioneer P4100DVD and I can play movies just fine and everything but I wanna take it to the next step and start burning DVDs with music videos. I can't for the life of me find any documentation on how to format the videos besides being in .avi format. I talked to Pioneer and they weren't any help. Anybody got one of these?

Does anybody know anything about the Soundstorm 2f2200 Force amp?

man this post puts a damper on upgrading alternators for me. Anyone know how to get around this PCM stuff other than rewinding/rebuilding.

I have a quick question concerning the Alpine 9886 headunit. I know it`s not the best to use dynamic bass features such as bass boost, but what about the bass feature that lets your widen your bass (Q0,Q1,Q2,Q3,Q4)? I notice the bass gets noticeably louder when I bring it up the scale towards Q4 but also less accurate, is toying with this feature when playing really loud bad for my woofer or am I good to go?

I’m having trouble tuning my mrd-m1000 to my 12” kicker l7t at 600 rms I’m not sure how to tune it properly to my subs specifications and I’m looking for help please!

well i have a amp (cactus 5kw) and it has four speaker terminals and im trying to hook up a 2ohm load to it. my question is if i hook 2ohms up to it will it be 2ohms or would it bridge it down to 1ohm?????? thanks

Can i use a standard charger to charger an agm batt with slow charge. And do you think this one will work. http://www.autozone.com/autozone/accessories/Schumacher-10-Amps-fully-automatic-or-manual-deep-cycle-battery-charger/_/N-2604?counter=0&filterByKeyWord=charger&fromString=search&itemIdentifier=181260_0_0_

Has anyone had experience with the Orion 2500.1dz model amplifier? I heard rumors of it running extremely hot. I want to run my two American Bass XFL 1224’s @ 1ohm and I’m kinda on the fence choosing between the Orion and Taramps MD5000.1. Any advice?

I was deciding on what brand of amp to go with I have cum down to five for my setup. The amps are Directed, Planet Audio, Massive Audio, Concept, and Autotek.

hey guys, i'm here to get some help with deciding whether or not to get a dash kit for an 08 accord for a new HU, but i'm having trouble seeing if the top screen and the steering wheel controls will still be active after putting in a new HU. here's what the inside of the car looks like. And here's the scosche kit Looks like it will fit in nicely, but i'm more concerned about whether or top screen where the radio station, tracks etc. are shown, will stay active or will be all shown through the new HU. Thanks for the help guys.

Between these two headunits which one would you choose and why? Im trying to decide which one I should get and want to know the pros and cons of both. If you have heard both then that would be great!!!

http://www.crutchfield.com/S-KJi47TPlPGC/p_130AVHP410/Pioneer-AVH-P4100DVD.html obviously doesn't cost $400 through them but I found a few sites that sell it for $400-450

Hey guys just trying to get a little info about some electrical from more experienced people. Im looking into getting a new alt, i have a 2005 chevy silverado 5.3L. Now i see iraggi has a 300 amp alt and dc power has a dual bracket kit that comes with a 185 amp alt, all in the same price range which would be best for me? Run a single big alt or have the 185 to the amp? Also i have a xs power d3400 as my starting battery, but i was wondering if i put a 900 cca as my starting battery could i put the xs power in the back and be ok? Cause i read something like you cant have two different sized batterys in the vehicle, i plan to run a crescendo 3500, just trying to see my best…

i have recently installed a subwoofer in my car, its a hertz hx250 d wich delivers 450Wrms in 2 ohm. It is driven by a Audison SR 1D mono amplifier wich delivers 460 wrms in 2 ohm. i just discovered that adjusting this shit was easier said than dine. So i wonder if anyone might help me along with tips and advises. Kay.

I am new to car audio so please pardon any ignorance found in my questions: I recently added a self Powered sub (memphis) to my aftermarket radio (kenwood) The sub is an enclosed unit I have power at the box. when I plug in both RCA cables I dont get any sound, however I can unplug one of the cables at the box and the sub sounds fine (to my untrained ear). I was just curious as to what might be causing this. Any answers would be appreciated Thanks

anybody have imfo or comments on db electrical's hi output alternator?

Ok, redoing my setup in one of my vehicles. Equipment is 1 JL 300/4 and 1 JL 1000/1. Hooked everything up and right off the bat, the low voltage light comes on the JL 1000/1 and the 300/4 won't come on. Checked voltage at amps and I'm getting 12 and both. Now, the only thing I did different from the previous install was I DID use a relay on the remote wire, this time I didn't. The deck is a Pioneer and I'm wondering if the remote wire on Pioneers can't support 2 amp turn-ons. Any one got any suggestions?

Hey guys, I've been trying to decide which head unit to buy. Which one would you guys buy? How does the screen clarity compare?

How do you prevent clipping, like prevent your head unit/source from sending a clipped signal and your amp from clipping a signal

just installed a brand new chevy alt on my mecury van , its chargeing but not fully i ran over my DMM so i cant test it till tomorrow.. theres 2 wires on the alt one is grey the other is white.. 3rd wire is the big red battery wire.. the gray im told is to battery power and white is a exciter wire but am told you dont have to use this white wire because at 1200 rpm itll turn on.. so a quick test and it was chargeing but i was using a test light for the time being and it was lit but not as bright as the vans own alt when i hooked it to van alt it was bright.. not as bright with second chevy alt .. any one have a clue why its not fully chargeing or am i missing something..…

i need 2 batterys that will replace 4 hc2000's any help plz

Okay guys so I got a 2008 ford escape and right Now I'm running two 12" Pioneer Premier TS-W3001D4 in a sealed enclosure. They are powered by a crunch 1500.1 mono amp. I am most like going to be selling the amp for around $150. So my budget will be around $250-$300. These subs do 1000rms a piece so I'm looking for around 1500-2000 rms. I am aware that I will have to upgrade to 1/0 gauge everything and prob get a capacitor but I'm willing to deal. I have been lookin at some hifonics amps that do around 1700 rms at 2 ohms and they are around 300 on some sites. But as always I appreciate any and all suggestions thanks, Nick

hi, i just finished installing the sax 200.4, everything was going well, i was just tuning up some of my bass levels and stuff when suddenly my front speakers just died and the subs kept playing. it wasn't loud enough to warrant any kind of speaker failure and the amp wasn't going into protect at all. my setup is two 4 ohm subs wired to 2 ohms running off channels 3 and 4 bridged and 2 pairs of components wired to 2 ohms each pair running off channels 1 and 2. my gains weren't cranked up at all, it was all sounding healthy, and then the front 2 channels just died. i turned it off and let it sit for a while, disconnected the battery, checked my wiring, nothing helped. does…
