Amp Wiring PLZ help.

[Kasnar]

Hi all i am just starting my setup, and have LOTS of questions but i think i get it, ok here's my question, my equipment is this:

Speakers
Pioneer TS-A1680R 50W RMS @4 ohms
Pioneer TS-D160R 60W RMS @4 ohms

Subwoofer
Polk Audio db124DVC 60-360W RMS
Dual 4 ohm voice coil

Amps
Boss Riot 745 100x4 @4ohms
Alpine MRD-M301 350X1 @2ohms

Receiver
Sony CDX F7715X 52x4 - 17x4 RMS

I'm thinking in wiring my speakers individually on each channel of the 4 channel amp, and the woofer in parallel for a 2ohm load on the alpine, what im not sure is if that i will be pushing too much power to the speakers, 100x4 and the speakers have a 50 and a 60 RMS, so do you guys think it could be a problem??

 

[CRX_dude]

ill say it will be alright, because thats just RMS, the max of those speakers are like what 220watts as what it says here>>> http://www.mobilcaraudio.com/catalog/item/342972/83997.htm
so ill think youll be fine

 

[Kasnar]

Well thnx for the quick reply, i just hope i don't get those babies broke but then again thx dude...

 

[CRX_dude]

no problem,

Actually if that is the rms of the amp....you could damage the speakers that are rated to 50 rms. The ones rated to 60rms will be fine. The general rule is to not go 50% or more above the rms of the speaker. Just because the peak of the speaker is more than the rms of the amp does not mean the speaker can handle that continualy. Also the sub will be fine if you wire the voice coils to a 2ohm load.

when it comes to systems im not much of an expert on RMS but they should handle it becuz the max watt is something over 100, but i would call up someone who knows more about speakers like www.crutchfield.com they always help me with questions but as of now i have 4 door speakers to a 300watt amp i sounds nice but the truth is i didnt install it the person that owned the car be4 me did he really didnt do so well but when my cars back on the road im going to fix it up add a crossover another 1200watt amp and either two Rockford 10's or one alpine Type R 12'

The sub will be fine as long as you wire it to both voicecoils..... (2 Ohms)

As far as the other 4 and that 100X4 amp. It depends on if that amps rating is RMS or not. If its 100W RMS X 4, I wouldnt use those speakers. You will have to turn the gain down about halfway or you will cook your speakers in a heartbeat. If thats 100W/channel peak, your speakers should be fine... Just listen for distortion.

he seems 2 know more of what hes talkin about listen to him... as for distortion u can tune it to your taste from ur radio or amp..

Yes, yes I do... I worked as an installer when I was your age actually!

as for distortion u can tune it to your taste from ur radio or amp..

Not sure what that means exactly but... If you hear any distortion, thats NOT GOOD for any component. Turn the gain/volume/bass/treble down.

i just looked uo your Boss amp, and according to CarDomain, it 100wx4 RMS LINK , so those speakers would not be a good match, my suggestion would to be to sell or return that amp (given the companys rep and history, for a little more, you can get an Alpine MRP-F240, LINK which puts out 40wx4 RMS at 4 ohms, which may be slightly under powering your speakers but not enough to do any damage. Another solution would be to go with a Clarion APA 450 LINK , which puts out 50wx4 RMS@4ohm, which would be just about right for your setup.
Or you could always buy new speakers, but your choices are slightly more limited and that kind of an upgrade would be more expensive, but heres a few options- Audiobahn ACS2062N, LINK not my first choice because i personally do not like Audiobahn, another option is Blaupunkt Vx652, LINK, also not personally recomened by me, probably the only one i would recomend out of what I found is the Kenwood KFC-1689ie, LINK, but at about $100 a pair...

My final thoughts/response- Go with a new amp, best bet is the Clarion, all your wiring sounds fine, it should work, but the Boss amp will not work with the current setup, as far as power wire goes, run at least a 4ga for each, with a 60amp fuse, but keep in mind you will be pulling around 128 Amps from your battery/engine, you may want to consider an alternator and battery upgrade running that much power.

Hope this helps

Distortion will kill the speakers faster than over powering them many times. When you hear distortion the speaker is trying to move physicaly past what it can. Ram your head against a wall....do it enough times and you are gonna break something. Thats how it is with a speaker.... when the speaker tries to push past its exursion (movement) point.

which puts out 40wx4 RMS at 4 ohms, which may be slightly under powering your speakers but not enough to do any damage.

Underpowering your speakers will hurt just as much as overpowering them....

Audiobahn is better than anything you put up also.... Fact and my personal preference.

 

[loccusst]

^^^ very true about under powering.

maybe so about audiobahn, i just dont like them from what i've heard and read my , 10W under powered isnt going to make that much of a difference, its better than being 40-50w overpowered. especally on 6.5"s when it seems he's gonna be running a sub and everything too.

 

[loccusst]

Naw...10 under isn't going to hurt. I wasn't paying attention to the 40 watt rating...guess my wife was distracting me or something. I wouldn't go lower though......try to find a good 75x4. Make sure the rating also has good efficientcy too.

well some people like to hear the distortion, but what i meant was he could tune his radio or amp to make it go away and he could also set it for his taste meaning how he wants it to sound

Well, I disagree. Hers why.. If you have an underpowered system, then when listening to it loud, you will always get potentially damaging distortion from the amp. Not Good.

However, if you get an amp thats overpowered, all you need to do is turn down the gain on the amp to get clean signals and can still play it as loud as your speakers will let you.

Thats how we did it at the shop. Most of the time, speakers are more inexpensive to replace than the amp.

thats all true, but my main point is that something in his system need to change, everything i put up was just suggestions, i cant build his system for him. I think we can all agree it would be best if he could match all the numbers, i was trying to make the most of what he already had and find him a reasonablly priced solution. It might be best to let him start over. I'm not trying to argue with you joe but just post some suggestions, i'm sure you have more experiance then me because i'm only 19 and have a budget setup in my car.

Yeah, im not trying to butt heads with you..just letting you know that IS the better idea at this point.

So basically, you dont have to spend another penny, just turn the gain down to about 1/2 way on the amp and have a good ole time!!!!!

damn budget gets in everyones way.. also it wouldnt be a bad idea to start all over but theres always that money issue, i loved the way my systems setup i wish i could do more but moneys tight and it does sound better then all my boys that have trucks and 3500+ systems in them..
