I am trying to upgrade my subwoofers. I currently have two kenwood 10s. I am wanting to replace them with 2 12s. My question is is there any rewiring in my vehicle that's necessary or can I just switch them out without error

Thank you for the instructions and detailed post. Just a few things I'd like to add with respect to the original author: bmlbytes

A high amperage fuse between the battery and amplifier is absolutely necessary. I have seen those high amperage (+12) low gauge (a lower gauge number and very thick) wires come loose from amplifiers/powered subs and then make contact with either the adjacent ground wire/connection or the vehicle body and cause fires if not properly fused. Well, for that matter, if the amps ground wire came loose and/or anything else connected to the grounded vehicle body touched that un-fused +12 line connected directly to the battery, it would create a direct short. I think most of us have experienced the awful electrical smell and the after effect of that condition..

Some decks(stereos) also offer dedicated sub-woofer outputs. The benefits of using those outputs is the ability to adjust the output that is sent to amplifier and then to the sub. I prefer that method (if applicable) than adjusting the knobs (potentiometers) on either the amp or powered sub to match the desired speaker volume. I understand the need for the initial calibration settings on the amp, however it is convenient to have control over the sub-woofer independently, especially if you find yourself next to a member of the older population (we all get there eventually) who tend to not enjoy the wonderful sensation of properly tuned bass.

I also find, with years of experience, that using crimped and soldered (and heat-shrinked) round connectors on every screwed connection to be the safest and most secure way to go. I know it involves removing/installing the screw and getting out the soldering iron and heat shrink. If you don't want to use connectors, at least solder the ends of the wires for a solid connection that also prevents fraying. If you don't plan on removing the sub or amp often, why not take the few extra minutes?

This might not be too relevant, however I have also seen every single clear plastic amplifier cover melt if mounted in a spot that receives direct sunlight in hot cars.

I really appreciated the original post, I hope this helps anyone else thinking of installing an amp and/or sub-woofer.

Hi Guys,

Can any of you help me. I have had my sub for a few years and recently I had a few things in my boot, as i went round a corner something fell and it pulled (ripped) one of my cables off my speaker (picture below). Is this something i can easily fix? and if so how?

Thanks

i think soldering it back and wrapping a ton of electrical tape should do it

selecting speakers for amplifier. This article has a huge mistake. One should never match amplifier power with speaker power. Here is why. Amplifier power measuremnt is watt rms. Rms stands for square root of the average of square. The important thing here is AVERAGE. The speaker power is expressed as the maximum input. In electronic we call this the crete to crete value.

If you pick a speaker with maximum rated input of 100 Watt to connect it to an amplifier with average output of 100 Watt, then never crank the amplifier to max or you'll end up damaging the speakers. The good pratice is to pick a speaker rated for 170% of the amplifier power. A 100 watt rms output should never be inputed in a speaker with less thant 170 watt mximum input.

If you follow this guideline, you won't blow up you speakers and improve sound output quality !

Great guide! Makes it really easy to understand the basic concept. If you want to learn more about subwoofers and amplifiers head to http://inovah.net/under-seat-subwoofer/

Congratulations on the enthusiastic hard work of both the author and the many contributors to this instructable.

I have to make one comment, though, which anyone installing powerful subwoofers into an automobile needs to be aware of.

Around the year 2000, the UK national Fire and Rescue service issued a nationwide advisory about people who have done just this. It is a fact of life that under the carpets of most motor cars is moisture, brought in from the outside atmosphere and trapped by the carpet. This moisture causes the metalwork of the car to rust. As the car gets older, the rusting becomes worse. Installing powerful subwoofers into an older vehicle puts a big strain upon the metal panels of the car, and the welds holding the panels together. The welds in some such vehicles involved in crashes were found to have spilt along hairline cracks, introduced by the use of subwoofers, or by panels splitting at rust points.

I'm not claiming that this will happen to your vehicle if it is old and you install subwoofers; I'm simply saying that it has been observed to happen by the UK authorities. Be careful. Regards Phil

My 06 sentra came with a rockford fosgate surround sound system. My subwoofer has stopped working. I have checked all my fuses and have even opened up the amp case to see if i can figure out whats wrong but nothing looks ab normal. All my other speakers work fine. So if someone had a solution please help. Another question, I have a 15' rockford sub and an amp to go with it, i want to install it into my sentra, but i have found out the stock stereo doesnt come with RCA jacks so whats is the best way to go about this? PLEASE HELP!
