I installed a system into my sisters car and a few days later her alternator left her stranded at work. After testing, results showed it to definitely be bad. Now, I've installed many a car audio system and I'm unsure what could be the issue.

During my install I came up just shy of enough wire to actually connect the amp to the subwoofers. So, I let her know I'd have to finish it the next day.

Now, the amp being connected but not pushing power to anything has never been an issue before. There was not a single wire connected improperly or exposed I made 100% sure (it IS my little sister after all).

Now she's having to spend nearly 300$ for a replacement and by her I mean myself.

I'm almost thinking since it was purchased as is used from a lot that it was already on it's way out or someone F'd it up before. If it WAS my fault, I'd like to learn from this.

I bought a dual kicker comp r pre-loaded enclosure. The rms is 1000 watts and peak is 2000. I’m going to buy an amp with 1000 rms and 2000 peak. All on 2ohms. Will this drain my car battery? Do I need to buy another?

The title pretty much says it all, looking for an amp for the above subwoofer. It is 6 ohm, dual voice coil and takes 700W rms.

My car has a fosgate system installed from the factory. Only a small amp and 8 inch sub however which I have subsequently blown. I can get quite cheap a fosgate p400-2 amp with 2x12 inch fosgate R2 subs. Will these work together?

I have a new JBL CP100 headunit and I am in the process of wiring the unit up.

I have all but the Yellow and Black wire hooked up, the instruction manual says that the wire is for 12v out. My wiring adapter (Axxess XSVI-9003-NAV) does not have a 12v out option.

I've tried to google it but have come up short. Any ideas on which wire I should tie it to?

I recently got a new radio installed in my 2003 Ford Focus (I know its old, but its well taken care of.)

After I left I noticed that the guy caused some damages to my cars dash while getting the old radio out. (At another audio shop I was told he probably used a metal tool, when he was supposed to use a plastic one.) It was also installed very poorly and eventually fell out. This has been over a week ago and I haven't had time to go back yet. Online reviews say that the owner of the place won't acknowledge any complaints and will claim your receipt is fake, so I don't intend to go back there. (It only shows the price of the radio and the installation, but does not have any details on it. It's hand written.) Except for looking at reviews of places beforehand, what can I do to get my dash fixed?

I am running 2 15in kicker L7's on a hifonics 1700.1 wired down to 1 ohm. yes the amp is 1 ohm capable. i havent even got to turn my settings up high yet due to during deep heavy bass my 2 farad cap has a volt meter on it and its dipping below 12v and my amp is going into protect mode. i just bought a huge additional battery and am not sure if i should hook them both up in parallel or if i should just replace the old battery with the new larger one, or if anyone has another suggestion please let me know. im itching to bang my new speakers and have to listen to them at 1/4 potential untill i figure out my power situation. any help would be greatly appreciated.

Hey, /r/car_audio!

Not the subreddit I frequent, but I really could use an advice! I'd like to upgrade the sound of my Honda. Nothing high end I'm afraid, since I'm more or less stuck with the stock head unit, as it has both audio and climate control integrated in it. One of the storage compartments can be converted to install a 1DIN aftermarket stereo, but I really don't want to go that route at the moment. I already added a Bluetooth module to the stock HU as I plan to stream Spotify almost exclusively.

With that out of the way, let's get down to the actual question:
Considering I'm not a complete basshead would you recommend running a 3-way system (2x 6.5" components + tweeters up front + sub) or 4-way (2x 6.5" components + tweeters up frony + 2x 6.5" woofers in rear deck)?
In a way, a 4-way system would actually end up cheaper and easier to integrate, plus, it would save space in the trunk. There already are 6x9" speakers in the rear deck, so I'd just need 6x9"->6.5" adapters.
Can this be done without a DSP, and will something like this provide "enough" bass? Or should I leave the stock 6x9 connected to stock HU as a back-fill, and look for a subwoofer instead?

For the front I've already bought these. AMP I haven't bought yet, but there's a guy selling one of these for a really sweet price.
Thanks in advance!

Hi Reddit,

I will shortly be buying an amp for my GMC Envoy. I have already replaced the factory speakers with Alpines, and will probably continue the Alpine theme for the amp. My question is, should I replace the factory wiring at the same time? Will better quality wire make much difference? Replacing them will obviously turn a reasonably sized job into a rather large one.

For the record, I have an Alpine CDE-103BT head unit installed.

Okay. This is my first post so go easy. I'm at a standstill and I'm just looking for some ideas or opinions...I currently have a kicker dx 1000.1 mono amp two kicker comp vr 05cvr104's sealed and stuffed with poly in my '11 530i sport. BUT, I've also got an 07cvr122 with a sealed box in storage. BMW's are extremely difficult to get sound into the cabin from the trunk. The 10's have a firmer punch, but the 12 is obviously deeper. In your guy's opinion, which would you go with? And why? If I violated any forum rules, I apologize in advance. Thanks.

I purchased two Rockford P2 subs in the Rockford box and have the Rockford 750.1 amp hooked up to it. They sound decent for now, but the bass isn't as deep as I would like it. I'm not sure what that box is tuned to, but I assume it's kinda high. With that being said, what is a good tuning frequency for a box that is a happy medium? I want the music to sound good, but I would like to still be able to hit some lower notes and have the bass nice and deep. Any thoughts on this?

Need some input on which to get, is that $60 worth it? How much louder would and be and what are the advantages of either or? Thanks
