Question about Car Speakers & Subwoofers

1 Answer

4 subs and two amps

That's fine I will try that. how should the RCA coming off of the sub woofer output from the radio go into the amp? Split one female to two male adapters and then what, which side should it go to after that?

I'm not that familiar with the insignia line but If the amps have an "input" and an "output" for the RCAs then run the RCAs in one, Then hook the output of that one to the input of the other. I did this with my 2 memphis 500Ds and it worked great. It also looks better than a couple of splitters, but yes You would just get two splitters with all female connections on them so you can plug 2 sets of RCAs into the one set. Also it doesn't really matter how you hook the RCAs up unless you are going for stereo sound then you would need to make sure the rights are hooked up together and the lefts are hooked up together. I hope I could help.

I have a clarion m 309 radio and I'm trying to hook up a fusion FM 402 amp for a sub woofer. I had all speakers playing but, I could not control the volume of the sub with the radio. I need to know...


Amps usually receive their signal through RCA wires. Your radio should have one pair of RCA outputs on the back. (red and white) You will adjust your subwoofer volume by adjusting the gains on the amplifer (little knob next to the RCA inputs of the amp), then you can turn up the bass on your radio.

I have a stock stereo and two subs with an amp in the trunk. Also two alpine speakers in the rear. Whenever I turn my balance to the left my subs don't play. What's wrong?


Hello.... I am sorry to hear you are having problems. The reason for this is that since you have a stock stereo, the shop (or person) whom installed the amp and subs used a line out converter. What this part does is allows the connection of RCA cables to the factory head unit. Almost all bass signals are always in stereo, so since you were only hooking an amplifier for just subs, you can actually just connect to just one of the rear speakers instead of connecting to the right and left. Just makes the install a little quicker. There is nothing wrong with this as I usually do the same thing in our shop. However, if you are going to be using the balance control, then you will need to go back to the shop and have them hook the converter up in stereo (to both rear speakers). Hope this helps!

Hi, you can split the preamp RCAs with Ys available everywhere. The amp input impedance shouldn't cause much load on the head unit. Let us know if you have more questions, and thanks for using FixYa.

I have a 1100watt sub woofers, and a 1000 watt amp. Will the my sub woofers, or amp blow out or get damaged.


Are those rms wattage?

Anyways, your subs (if you have two) will double the power of your amp, meaning your amp will be under powering your subs. Nothing will get blown out but will never see their full potential. But if you were to use single sub with your amp then you are more likely see the full potential of the sub and amp.

2 subs=2200 watts is just twice the power of the amp output power!

Can i connect the amplifier and subwoofer to the built ford fiesta radio


If your amp has rca jack inputs only you will need in-line filters to reduce the stock stereo speaker outputs down to less than 3 watts. If your amp has high power inputs you can use those. If your amp does not have a built-in crossover then you will need to install a low-pass crossover or filter before the amp so the only the bass comes thru or the sub woofer will have major distortion. Another problem is the amplifier needs a turn-on signal for the blue wire and most factory radios do not have one. That means you will have to tie that wire into the switched 12v wire from the vehicle so the amp comes on when the key is switched on. It can be done be done but I don't think you will be very impressed with the sub due to most factory stereos have a limited bass range. Most aftermarket head units have built-in crossovers and sub outputs. They also produce much better sound than the factory unit. So in other words yes you can.

Ohm calculations; 4 and 8 ohm sub woofer?


+ output from amp to + input of 4 ohm to + input of 8 ohm AND - output from amp to - input of 4 ohm to - input of 8 ohm is a parallel circuit = 2.66 ohm impedance load for amp
+ output from amp to + on 4 ohm - on 4 ohm to + on 8 ohm - on 8 ohm to - of power amp is a series circuit = 12 ohm impedance load for amp. Clear as mud??

Sub woofers and amp


first of all is the amp a four way amp? if so then you need to know what the watts of the subs are (you dont want to melt them) wire + and - of channels 1 and 2 to one sub and + and - of channel 3 and 4 to second sub, nice thick lead from battery positive (fused) to positive terminal on amp thick lead from a good earth point to negative terminal on amp run a set of rca leads down the opposte side to the positive wire to prevent interference, run thin wire from remote wire of radio to the remote terminal of amp, rca's are plugged in at stereo and at the am. may need a RCA splitter to be able to power all four channels

Good luck Davelee

Could a ground stop your woofer from working?


First check the speaker wire from the amp to the sub, see if it's connected right. Second check the rca cables that goes from your amp to the back of the deck. I f both wires are still connected fine try to replace the rca cables. If it still doesn't work the rear out put at the back of your deck, where the rca's are connected are bad. FYI deck is bad.

Sub Woffer System


Could be Faulty RCA wires (they bring the sound from the radio to the amp) or a bad ground (the larger black wire coming out of the amp) This is under warrranty and you should not have to worry about it... bring it back, they make fix..

OEM gm stereo


If your amplifier has what they call High level inputs (basically inputs on the amp that you run the speaker wires from your radio into), you can splice wires from where the connectors are on your rear speaker(s), still leaving the speaker hooked up, and use those as an input into the amp. If your amplifier does not have high level inputs, a convertor is available to turn an audio signal from your radio output speaker wires ( spliced in just as above, leaving the speaker hooked up), into an rca output jack. Or the best thing to do would be to buy another say 2-4 channel amp w/high level inputs and rca inputs and outputs, and run your rear speaker wires into the amp. Then you'll be able to run the rca cables out of that amp and into the sub amp, and you'll have the new amp to power your rear speakers or rears and fronts. That would be ideal. But, A convertor is your best bet. Got em at best buy, circuit city, etc. Hope this was helpful.
