4 channel amp wiring question, opinions

[swift 501]

I am thinking of going with 2 sets of components for my front stage and doing away with the rears.(maybe) I have a Alpine PDX 4.150 that does 150 x 4 rms to each channel. Right now I have the fronts on the front channel rca and the rears on the rear channel RCA's.

So I do not mess with imaging too bad do I just run RCA Y spitters just on the front channel from the head unit so I can use all 4 channels of this amp?

I need something to keep up with two 18's and I think my current front stage would but since my rears will blocked by the huge box I might as well double up front and use all 600 of this amp

Do you have front and rear rca's coming off the H/U and no sub outputs?

[swift 501]

I do have front, rear and sub rca's coming from the head unit. Both front and rears are going to the 4 channel currently, but I thought it would be better if all fronts were coming off the same signal? Maybe I am wrong, thats why I'm asking.

Thanks

You can adjust that with your head unit.

You must not understand my question at all.

I'll give someone else a shot at it.

I understand you want all the signals to be the same.Do you want to use the second amp channels to run a sub?

Do you have a sub amp?

I have a Sundown 1500v.2 on the sub RCA's. (didnt think that was relevant)

I have a Alpine PDX 4.150 with the front RCA's on two channels to the front components and the rear RCA's on two channels for the rear coaxials.

I want to run two sets of components up front. I did not think it was a good idea to run the rear RCA's for the second set of components.

To use all 4 channels of this amp I have to run 2 sets of RCA's to it. Should I split the front RCA's coming from the head unit so I dont have a "rear" signal going to the second set of front components?

EDIT, after looking at the pic of my amp I think I can switch it to run all on one set of RCA's. If so I should have done alittle more reasearch on my amp before asking. Maybe I made it more complicated than it needed to be.

It won't matter, no. A lot of people use a 4 channel amp for just their mids and highs in their front doors. I'll be running 2 channels to my mids, and the other 2 channels to my highs on my 100.4. They're just labels, they're sending the same information to the amp. Whatever you have the setting on the amp or your HU is a different question.

[swift 501]

This possibly could be the dumbest question I have seen yet and I made the damn thread!!

LOL

[swift 501]

So bridge the amp on just the front RCA's or split the RCA's and use all 4 channels independently? I wonder which is most efficient or maybe it will not matter?

It runs 4ohm bridged or unbridged.

is splitting rcas like wiring speakers in parallel? for instance if you had 4volts preamp would it create 2volts per channel? dont mean to thread jack but my question does kinda pertain to your topic.

btw what kinda of components are you running? i was thinking of doing the same thing except with except i would take out one of the tweeters.

If so then I am better bridging the amp and not splitting RCA's. Didnt think of the voltage. hmmm maybe someone can answer that.

I am running Rockford T2652s up front and would probably just add another set.

No you dont understand what he is asking and no he doesnt want to use the other 2 channels on his amp for subs. He wants to run two sets of components to his 4 channel alpine amplifiers, he wants to know can he use one set of 2 channel rca's with a y-splitter to turn the end of the rca's going into the amp to a 4 channel set. You can but Ive heard you loose some signal/output by using y-splitters so I would just keep the front and rear rca's plugged up unless your amp had a 2/3/4 channel switch. Front and rear will send the same signal

I think by running splitters you will decrease the ohm load from 4 to 2ohms

You cant run two sets of components at 4 ohms bridged, 2 sets of components per side will result in a 2 ohm load.

Do some research and you will find out splitters do not change the ohm load, only adding/deleting speakers can change ohm loads and wiring configurations. Please be advised with what your saying as other people read this thread for the same answers, we dont want any confusion or misinformation.

Maybe he should be the one asking questions....LOL

Here is my amp specs BTW.

Naw i doubt it since he is the one who claims to hit a 150db with 2 Icon 12'' and a AQ2200d but couldnt provide evidence when i asked, not that guy. He should do more than ask questions, Im glad he is trying to help but you gotta know when you know something and when you dont.

Read under the controls section here and it tells you no y-splitter is needed and one set of 2 channel rca's will be enough to run all 4 channels. You just have to put the signal setting on the right feature:

lol so i checked just to make sure and splitting doesn't change the voltage. sorry for any confusion...

TEST: same volume, 1K hz test tone, could've done a 50hz but i dont have high pass on the doors, shouldve done it though cuz the 1K hurt my ears :/, 2 DMM, same .5 volts each. i did this at low volume 15 out of 60.

those rockfords are sweet, i just installed the t1 6.5s in my uncles car last week... and they said it wouldnt fit B)

custom FTW!!

Sorry I guess I didnt understand your question.
