In my Mustang I have the stock speakers in the front, running off the deck only. The rear speakers were swapped and are running off of a 2way amp. I used an empty sub speaker box to mount the amp on and now Ive been thinking, why not put a sub in the damn thing?
I was reading up on 2way amps, and that is what it sounds like I need. I want to still run the two rear speakers off an amp, as well as the sub running off the amp too. If I just bridge the sub into the amp I have currently, the power will be the same going to the 2 rear speakers as well as the sub, and that doesnt sound right. I need a 2way amp that has the separate sub output. My deck also has the rca "SW" subwoofer outputs in the rear too, but I dont know anything about how those work.

ok first its 2 channel amp not two way.

and you cant run speakers and sub off that single amp. pick one or the other.

if you had a 4 channel amp then you could. but not from a two.

you would need a separate, preferably mono, amp to run the sub

the rca outputs are low voltage outputs that you run to the amp to give it the music signal.

So this wouldnt work? Whatever I was reading friday said that some 2 channel amps will power two speakers and a sub. what I dont know if whether the sub runs on its own channel

u have no clue what ur talking about. I have a mono amp powering 2 subwoofers. It's called splitting the signal.

jimi, if u want to run 1 amp u can split the signal from 1 channel over to the rear speakers and have the other channel powering the sub.

Or u can go out and by any amp u want, and wire it directly to the sub.

I've had 4 channel amps powering 1 sub, 2 subs, 2 subs and 2 speakers... etc

excuse the filth, but my top tore and i can't bring her to a car wash and have to beg friends to let me use there driveway



thats a mono amp with the signal split powering.... dun dun dun...... to dif speakers

For one. Why would you replace the rear speakers before the front speakers and two, you can't run a sub and speakers off of a two channel amp.

yes u can, the same way u can run a mono amp on 2 subs.... if it wasn't dark out i would take a picture to show u i'm not insane

[G.T. Rags]

ok, basically whats ging to happen if u run the sub and speakers off the same amp is that the speakers are only going to be receiving the low bass tones that the sub is recieving. In order for the speakers to be utilized fully they would need to receive the full frequency range of the source, which they won't be able to do using the subwoofer preamp outputs.

So i basically should just buy a single channel mono amp for my sub then? I only have one, dont need two. I like my trunk space, what little there is. and how should I go about connecting the power? using a fuse block thing to split the power into two?

I swapped the rears because thats where the low end comes from. But in this case with the Mustang, it made hardly any difference, Whereas my Monte Carlo sounds like it has subs hitting in the trunk with only 2 6x9s on an amp.

i'm not to sure on the correct gauges in power wire size, so bare with me.

u can pick up a bracket that will take a 4 gauge wire and turn it into 2 8 gauge wires.... i don't know what size u use as of now but i'm sure u can split any guage as long as it's not speaker wire thin

and u don't have to limit urself to a single channel. When ifirst got my subs a had a 4 channel rockford p4004 powering them... i just bridged the signal...

[mxnate116]

why in the hell would you run two 6x9s and a sub off the same 2ch amp?

just because you can doesnt mean you should.

that would sound terrible. you would get mud coming from the 6x9s and little from the sub. or music from the 6x9's and crap from the sub. either way one speaker is not going to perform like it should. and you would most likely cause the amp to fault because one channel is most likely going to be running at a different ohm load then the other.

what you should do is keep the 2ch to run the 6x9's in their useful range and get another amp for the sub. which is what a logical person would do. instead of jerry rigging one amp to somewhat work.

and yes you can run more then one speaker on a mono amp. but you should only do this with subs because then you retain stereo for the normal speakers. and thats assuming you have the subs wired the right way to use the full power a mono amp provides.

[JiMi_DRiX]

I get what you're saying. I wasnt planning on rigging anything, I was wanting to get the facts first. For the time being, I just took the 5x8's off the amp and amp running them off the stereos power, and put the sub on the amp. I'm working on getting another 2 channel amp for the 5x8s though. They sounded much much better with the amp.

Now what is the best way to split the power? and where should it be split?

[mxnate116]

yeah deck power is fine for the rear speakers. i would recommend the 2ch amp for the front speakers because that is where the majority of your sound should be coming from. in front of you not behind.

there are two ways you can split the power

1) buy a distribution block they run about 20 bucks and split the power wire into two and run a separate wire to each amp.

2) daisy chain the amps. hook up your power wire to one amp then run a shorter length of wire from the first amp to the 2nd.

you should split the power as close to the amps as you can so you dont have to re-run alot of wire.

and sorry if it sounded like i was directing that last reply to you it was more to 96gt i wasnt trying to bash on you.

[JiMi_DRiX]

I didnt sense any "bashing" man. No worries.

My deck, although aftermarket, does not power my aftermarket rear speakers enough for them to hit their sweet spot. The front speakers are stock, and sound like they are at their peak with the new deck.
I just want to run the sub on one amp, and the rear two speakers on another amp. I will get a distribution block and just do it that way. The stereo isnt a main focus in this car, but I'm also a musician and I like to have my music sound good.

Thanks to everyone for their advice and help.

[mxnate116]

hey man as long as it sounds good to your ears thats all that matters.
