Connect the power cable from the battery into the spot on the amp that has one of the following markings do not connect it to the speaker positive : B+ Batt. Wiring can also change the amount of Ohms that you are drawing. Simple reason why: that sub is going to sound like bullox and you might blow it! Install it so that when your get your wires to it, it will be ready. If it does make noise like from the engine , add a switch so you can turn it on or off. I don't know much about cars except for how nice their sound systems are.
There is also a wiring diagram below. Cover the wire with electrical tape. Then set the sub's volume control to provide the level of bass support you want. As before, turn up the gain until you hear audible distortion. This is a very good beginners guide to car audio. Connect this end to the wiring harness of the stereo unit by twisting together the wire coming from the wiring harness and the remote wire. I'd love to hook it up to a good receiver for my computer audio, but I'm just not sure if that's a good idea.
When the stereo comes on, so will the amp. The example attached to this step wouldn't be sufficient with its pathetic 18 amp peak power. This process will work with most stock stereos, and all aftermarket stereos. With small speakers with 4-inch or smaller woofers, you'll set the sub's crossover frequency at 100Hz or higher, and with speakers with 5-inch or larger woofers, 80Hz or lower. I bought 2 channel outline converter from e bay and I need to tap into factory cable speakers but not sure with speakers I should tap. That's why you push the wire from the interior.
They aren't very expensive any more. If yours is buried under the carpet or run nicely under your back seat because your amp is far from your sub, don't rip it out. The result will be a very muddy sound, as you'll be hearing the mids and highs out of the subwoofer. However, if you don't have this, then the video will instruct you on an alternative method as well. As long as your amp can handle the 4 ohm impedance, it will work.
I usually make a small pilot hole and then increase the bit size until the hole is big enough for my wire. Locate the sub woofer positive and negative cables. Then depending on the amp you'll need to supply a small amount of voltage to the amps' blue remote power-on wire. You're concerned with the +12V section. Hard to do without hooking the sub up to some kind of crossover or equalized amp before connecting to the receiver. Start by finding an opening in the car's firewall.
Just go to any car audio shop and buy some speaker cable. If so, that means you do not need a crossover which some posters above mistakenly called an equalizer. Well, thanks for all the insights. When looking at speakers and amplifiers, do not look at the peak power. This wire tells the amp that the stereo has turned on, and that the amp should too. By the way, I'm pretty sure the sub is 4 ohm, if that's at all important.
It also goes into a brief description about how you can install your speakers, mount them or make custom enclosures. Now that the higher number means it's less sensitive if the knob has numbering on the outside. If you cables must be seen, then cover them with plastic wire wrap from the auto shop, available in red blue and black most commonly. Smith also works as a research assistant in the health and aging field. Installing car audio amplifiers is a step by step process which I have outlined here.
I won't explain bridging but its easy and you can Google it. Try something cleaner, maybe acoustic, that you're familiar with. The other side of the firewall should be the inside of the car. So what will we need to do this? Connect the other end of the speaker wire to the + and - on the speaker box. Now divide that by 12 as in 12 volts and you get 25 amps. Now don't take my word as gosple but I'm sure you can hook it up fine as long as you don't crank the reciever too much.
What I have done is wired the speaker output, into the rear speakers. My subwoofer has stopped working. Now strip the yellow wire and the black wire next to it so there's about a quarter inch of metal exposed. Make sure it's long enough to reach from your computer to your amp though. I will show you how to do this with an aftermarket head unit stereo. You want the fuse as close to the battery as possible. Make sure you tape the place where you wired the fuse to the wire, so you don't get a short.
It won't be used and you don't want it shorting out so wrap it with several layers of electrical tape. It could hurt your speaker or reciever. The wire must be snaked through to the passenger compartment of the car and should be installed under the door sill and carpet. This is pretty self explanatory, but for those who don't know: Put the speaker in the box, making sure the flimsy thin gasket thing is on it. Your left and right positive to your positive cable, your left and right negative to the negative cable.
