Hey, just having some speaker issues... I disconnected them to hook up my Alpine speakers and I didn't do anything with the stock wiring... Unplugged the Alpines because they didn't sound right, as ttocs said would probably happen... The 5.25s distorted way too low with pretty much any amount of bass which has never happened before, the 6x9s sounded fine. Anyways, my friend offered to trade his 2 Alpine Type E 12s for my speakers which I did. Plugged the stock speakers back in, 99% sure I plugged everything in... No sound from the speakers. Right now all I have playing is the 2 12s and 3 or 4 tweeters. Tweeters are trying to pick up everything and it sounds alright for just tweeters I guess. I have the bass turned down to -7, the lowest it'll go on the head unit, so the tweeters don't try and play lows. Considering its only tweeters and subs playing, it sounds alright, but if anyone has any ideas as to why the speakers aren't working, let me know, I miss my mids, lol. Also, should I just go buy some Type R 5x7s or what? If I do that, would I need to run a whole new power wire from the battery to amp for the speakers? I'm already thinking about buying an Optima battery at least because the subs make the lights dim and I imagine that'll drain the battery fairly quick. One last thing... If I do end up getting 2 new sets of speakers, could I put 5x7s in the rear enclosure or would that not sound good for the speakers because of the lack of air, or would I just have to drop out the rear enclosure completely? Alright, lemme know if anyone has any ideas, thanks.

 

One more thing... If I got a couple sets of components, would I have to wire them any special way? Would they fit in the stock 2002 speaker holes? These are the components I'm thinking about, and I've never hooked up components before... Just curious if it would fit with minimal work...

I have a 4 channel amp that supplies 100rms to each channel, pretty much enough to power them I think... This is the amp that I have.

I was thinking I could do components maybe to keep midrange in the doors and put the woofer in the rear enclosure... Let me know if you think it'd work and if it'd be a good idea to get them instead of just normal 2 way Type R 5x7s...

 

got yer pm, no worries.

what year is this in again? mach or not?

 

2002 mustang, mach 460.

Also, these are the components I'm thinking about.

I would go with the Type X ones, but those are a little more expensive... Just a little... As for the normal 5x7s, these are them.

One more thing I noticed... The components say that they are 110rms, think that would be for one whole component set or would it be double that because of the woofer and the midrange? Also, would the 4.100 amp be enough to power them or would it be bad to not be able to power the extra 10rms? Last thing... The bottom of the page about my amp says that its a full range only... Would that not work with the components? Thanks

 

I don't pay attention to a speakers rms or peak power rating, it is not really important. Match its impedence with your amp so that you can feed them as much power as you can, keep the signal clean and out of clipping and you will be fine.... when the amp says that it only plays full range that means that it does not have any cross-overs built in so it would not be good for subs.

 

As for the impedence, thats one thing that I like about Alpine PDX amps. They play 2 or 4 ohms the same, doesn't matter. Since I have that amp, I'm guessing that I can't use them for the components because of the woofer part? Well, if thats so, I guess I'll just get some 5x7s or something. Think the 5x7 speakers will fit the 6x8 hole? And would I be able to mount the 5x7 speakers in the rear enclosure or would that be bad considering the lack of air getting to the speakers? One more thing, this is about the subs... I traded my old speakers for the subs and they came in the box that my friend was using, which was made for trucks I think. Not sure on exact dimensions of the box but right now they are in the trunk underneath the rear enclosure facing up and slanted slightly towards the front of the car. Inside the car it sounds really good, but outside all you can really hear is the trunk rattling... I know rattles just kinda happen, but if I had a box that was more for that car, do you think it would cut down on the rattling or would it matter? Thanks.

 

listen to me - that amp is perfect for any kind of speaker EXCEPT a sub woofer specifically made for bass. It is made to run either a coax or componant speaker but is made to do what you are wanting to do with it.

5 x 7, 6 x 8 = same thing....

A different box may help your rattling problem or it could make ti worse. To fix rattles you need sound damping(NOT damENing) which brands like 2nd skin, dynamat and others are made for.

 

Alright, thanks for the info. I guess I'll put some money towards some Type R 5x7s and maybe some fatmat. Sorry if I'm being difficult here, but I'm just trying to figure out what'll work correctly with as little error as possible, lol. Question... Would I be able to mount a 5x7 speaker in the rear enclosure and still have it sound right or would it sound bad since the speaker would be in an enclosure?

Also, I'm sorry, I'm really trying here, just not understanding completely I think... You said that the amp would run a component speaker but its not for a sub woofer. Since the components are Midrange, Tweeter, and Woofer, would the amp work to power those?

Thanks a lot for all the help and I am listening to you, I just want to make sure that I understand this whole thing completely before I go and spend more money on something that isn't going to work... I'm pretty sure I understand everything except for the "speaker in an enclosure" and the components with that amp... If you're not too tired of trying to explain this, mind explaining a little more? Thanks again for all the help.

 

no worries, it was a bad day yesterday.

a componant set is made up of a woofer, mid and tweet but there is no sub-woofer in the package so again, that 100.4 is perfect where you have it.

Putting the rear speakre in the enclosure will not hurt anything, try to put the tweeter near it but it is probably overkill to have componants in the rear, you would be fine with normal coax speakers.

 

Alright, I'll just go with the 5x7s then. Since its just gonna be normal speakers, there'll be no problem hooking them up since I already have all the wire ran. I think... Wait... Alright, one more thing. Since I have the subs in there right now, am I going to have to run another power wire to the battery? I have 4 gauge running from the battery to the subs and that wire was a pain to run... If possible, I don't really want to do it again, lol... Oh ya, I do have a couple Distributor Blocks from the Rockford Fosgate wiring kit that I used if I can use them. Not completely sure on how to use them, but I think I might know. If I use them for the power cable, could I run 2 sets of 4 gauge in and have 4 gauge going out to the battery? I'm just not sure if 4 gauge alone can handle a total of 900rms... Also, when you say I could put the rear speaker in the enclosure, do you mean I could put a component woofer back there or a normal coax speaker in the enclosure? I just want to make sure that its all going to work before I spend a weekend or so trying to do all this. Thanks again.
