The other day, my subwoofer suddenly cut out and I traced the issue to my subwoofer pre-outs on my Kenwood DDX-319 head unit. Troubleshooting done so far: No AC voltage comes out of the subwoofer pre-outs on the head unit at all Connecting the sub amp's RCAs to the rear pre-out produces sound from the sub (ruling out that it is my amp or subwoofer) There is no resistance (0 ohms) between my pre-out grounds and the case of the head unit (leading me to believe it is not simply a blown fuse in the head unit) Everything else on the head unit functions as intended My head unit is out of warranty by a couple months. I emailed Kenwood about the problem, but …

A friend of mine has been quizzing me on what amp to get for his highs. Suggestions?

Lately I have been having some problems with my alt for some reason. Two days ago on Friday it was working fine and steadily charging around 14.4 while I was driving. Yesterday out of no where while I was driving (not listening to my system) it just decided to drop down to about 12.9. Today while driving I noticed that when I pressed the gas my voltage would severely go down but then if I let off the gas while in gear my voltage would start to rise. When I put it in neutral it would go back down again. I thought I could get away from getting a new alternator for a while because I am only running about 2500 rms, I have my gains set a little lower because of my electrical…

What is the difference between a kicker zx.1500, saz-1500d, and a rockford fosgate T1500-1bd?

lately my kicker zx1000.1 has been acting wierd, when i first set everything up, it sounded great, then, not so great. before the sub was broken in ( a 12'' fi fully loaded bl in a 2.25 cu ft box tuned at 32 hz), i had the gains set and everything with the dmm. now, at the same voltage, my sub sounds like its distorting badly, and i have to turn the gain all the way down. my hu's setting are set to -2 of all bass enhancement. and im not using the bass knob for the amp either. do fi bl's sound like this when theyre broken in? i know there more of a spl type sub made to get loud, but i have only had 2 other subs so i may just be overreacting. any help guys?

Nevermind

Wanting to add to my existing alarm, thinking about adding perhaps two exterior sirens, current one is hurting. Also like the idea of having one or two piezo sirens inside the cabin. I have seen these refered to as pain generators. Any of you have input on particular brands which might stand above others in performance? I also wanted to know if adding the additional sirens and alarms will require any additional wiring aspects, I guess I mean can I just wire multiple sirens or will I need additional installation knowledge or products? Thanks for your help and input. Chop

So this is what I am thinking. For my 2 zcon's I need more. They want more. Currently have a 2500d but was thinking of going with a 4500d. Or maybe even 2 2500d's strapped. Only problem is, zcon's are 1 ohm. Every where I look, for strapping u want 2 ohm. Which way should I go?

i put in my new 200 amp from the group buy at ca.com forums. when over 950 rpm or so, it is awesome, rarely ever drops from 13.5 volts and when it does, not under 13. (going by my dash gauge anyhow) under 950 though, the voltage will drop almost to the red, to around 9.. red is at 7.5 or 8. having the stereo up drops it almost another half volt. either way, that is way low voltage. i could just turn my idle rpm up to 950 but it would burn more gas, and i like the rumble of a healthy v8 idling around 700 rpm. i do not have my optima yellow top in yet, waiting on terminals. im using an old, cheap, autozone battery, with 4 gauge run to the back split into 2 8 gauge wires. …

Hi everyone, I'm looking to finish the big 3 in my car. I already have a 0 ga wire from battery - to chassis. My alternator is difficult to reach. I must "lift" the car to reach it under the motor. My question is : can I take a point anywhere on the engine block and ground it to the chassis of the car (with a 0 ga wire) ? (I know !). That would be the third part of the big 3. I have a stock alternator, maybe the (+) alt to (+) battery part is not a "must do" part for me. Another question : I have one 0 ga wire with ring connectors, and one 2/0 marine grade wire with ring connectors too. Which one would you choose for the battery to ground, and for the engine block to g…

Did a quick search on the forums and came up empty. I saw somebody post a link to one on ebay a while ago, but I can't seem to find it. I'm not positive that that is the correct name... When I say voltage meter, I mean something like this. Feel free to correct me if I'm using that phrasing incorrectly. Just wonderin where I can find the best one for the money.

i plan on buying a sundown 2000D mono amplifier .. they will be powering 2 12 inch FI BLs and at 1 ohm. i have a stock alternator and battery and i wanna know how i should go about this. i know caps are bogus ive read the forums so i was thinking about replacing the stock battery with a kinetic one. would this be enough or would i need more ? i strained the alternator on my last car to the point were i cudnt start the car anymore i deffinitly dont want that happening again. all help is apreciated

Okay so im debating over some amps to power my two RE SE 12's. I've benn looking at some and tell me what you think. Hifonics 1608D Us Amps XT2000D Us Amps MD1D AQ 1200D My budget is 190

I have the 9813 model head unit it has a time delay feature , easy to set by plugging in your speaker to listening position. Alpine`s web site can give you the settings for your TD . The Bass Focus is a separate feature but when adjusted it affects the time delay. I would like to use the Bass Focus but I do not understand the instructions completely. Is any one else here using this feature and how is it set?

I'm working on a little project where the only available power source is a 12 cell Ni-MH pack, starting at 16.8V fully charged, but dropping to 15-16V after some use. Would a HU run on this, or would it go up in smoke?

I have a JBL 1200.1db amplifier... what are your guys opinions on this amplifier?

Do you guys think 2 of the AQ1200D can push 2 18 Fi Bl dual2 ohm?

Ok here's my problem. Whenever I turn up my Head unit (New Sony Xplode) past a certain point my amp will shut off. As long as I have my amp turned pretty far down it wont do it. But I feel like I'm being robbed of the potential of my speakers. I thought that maybe it was the amp so I took my other amp out of my other car and it did the same thing but even quicker cuz it's a 900w Lanzar and the other one is a American Pro 600w. I've checked all of the connections way to many times and never found any problems. Someone told me that the ohms has to match up on the amp and on the subs but i've never heard of that. If any one has any ideas please let me know i would app…

Anyone know anything about them. My buddy wants the CR5000.1.

Anyone fix amps!?

My battery keeps dying and I think I might have a parasitic draw. To simplify the troubleshooting process I would love to buy a DC ammeter that can measure 10mA to 500mA+. According to the M5 owners group 20-30mA at the off and settled position is normal. Since I am buying one it would be a cool tool to measure current going to my speaks as well. Anyone have recommendations on where/what to buy??

Has any one used these. Good or bad?

I need help deciding on an amp for my two SDC 2.5 Dual 4. Looking in price range of $400 or less. Looking for 1200 to 1500 watt at 1 ohm. Any other suggestions are welcome that fit what i am looking for.

I will be running a little over 1000 watts rms, probably around 1200, will there be the need to get an optima yellow top?

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..
