Amp?
 

Hey, I was thinkin about putting a 10" sub in my truck, but It'd take up too much space, and probably be to bassey for me, and I was wondering how many channel amp am I gonna need to run 4 or 6 speakers? I figured I'd just put some 6x9's in a box, and two 6.5" round speakers in the box with em and it'd be fairly bassey for me with an amp, any help is greatly appriciated, also, for you single cab guys could you post up some pics of your systems? I'm having a hard time fitting speakers back there.. :(

here are my mtx's they have good bass and sound really nice im running them directly off the head unit, no amp.

i had to cut a hole in the grille of one of the subs but otherwise they fit good.
here are my mids, i took them from a home surround system and cut them to fit.

4 speakers = 4 channel. your head unit wont put out any more than 4 channels

so I need a 4 channel amp to run them? should I leave out the 6.5" round speakers and just use the 6x9's and my 4 inch ALPINE dash speakers?

if you dont care TOO much about sound quality than go with the 4" up front and boxed 6x9's in the back. I had a setup like that in my 4runner and it sounded pretty decent.

You could use the amp built into your head unit to power the speakers, or buy a 4 channel amp to power them.

If you want a good setup for your truck then get something like this:

Some kind of nice Head unit would be a good thing to get. Not a must but very good. Alpine is the best.

For amps get an A/D/S/ amp off ebay. They are older but they are by far some of the best amps ever made. I just got a P850.2 and a p4100 amp for my system. I messed with them the other day and just wow.

They will be replacing an A/D/S/ 6.25 amp that i have now. For you a PH15 amp would be ideal, it is 6 X 50w bridgeable. So you can run 4 door speakers and a sub if you want. or run your door speakers with some nice power.

There are plenty of other models out there as well, any of them will work great. even my 25w amp i am using outperforms MUCH MUCH "higher" wattage amps.

Then get some door 6.5" door speakers, just some kind of brand name (and NO, sony is not a brand name). Don't do the 6x9 in a box, you would be MUCH better off spending that $$ on some better door speakers. Then get an 8" or 10" sub for behind the seat. This will sound much better than 6x9's in a box.

The next best amps out there are the alpine PDX series amps. Just a few good brands for the speakers: RE, ADS, Focal (pricy though), ID among others.

For subs go for an IDQ 10" or i think they might have an 8". for the price you can't beat them at all. They are also nice and small.

i had a 200 watt amp hooked to 2 6x9 kenwood boxed speakers and the deck hooked to the 4in speakers under the dash and it was decent

i now have 2 12' dual subs with a 600watt amp with the deck hooked to all the stock speaker, it has awsome bass but it definatly needs new speakers in the back doors

Yeah if you were to just use an amp for the stock speakers it would make them sound much better. If you were to also get new speaker them that would be quite nice!

I am amazed how muc a differnce am amp can make. I never really relized it until i get this "little" 25w a channel ADS amp. I hooked it up not expecting much (for the price i paid i didn't care) but those cheap speaker sang better than ever! not only loud but with some real Quality!

I am in the processess of rebuilding my system as we speak. I have the amps and some of the other things, still need the door speakers though, but i already know what i am getting... Some orion (ADS owned) prototype carbon fiber cone speakers that are just increditable!

NOT TRUE
There are lot's of headunit's out that have front rear and sub output's now a day's.
I have a ROCKFORD FOSGATE headunit with all three and run into a PHOENIX GOLD 6 channel amp to a set of PHONIX GOLD 10's , PG 6.25 with crossover's and a set of PG 5.25's with crossover's all which are completely ajustible seperate of each other.

Sorry I was asking for fact, not opinion, Like Sony's stuff, it sounds the same, if not better than jvc, kenwood, pinoneer, and brands like that, I have some alpine speakers in my dash, personally I don't think they're that damn great... I'm not looking to spend 500$ on a sound system I just wanna know If I can run all that ...Would I be better off to put the 6x9's in a box with a 10" sub and run my dash speakers with an amp? Cause I heard I could use a two channel amp with all that.. :think:

Very true, i had meant to say something about that as well. My HU also has 6 channel output.


Sony being junk is not opioun, it is fact, ask ANYONE that knows car audio. The ONLY speaker they have that are even ok are there new 4way speakers. Their subs SUCK. I know i have one, i hooked it up to my amp for the heck of it and it was litteraly 1/3 as loud and clipping as the $50 DIYMA sub that I got off ebay. NO comparson at all. All those other brnads you have listed are also cheap brands, that is why there is not much differnce. alpine makes great amps and HU's but there low end speakers leave a lot to be desired. There comp speakers are great though.

You *could* use a 1 channel amp to power 100 speakers if you wanted to but it would not sound good and even if it was hooked up right would destroy the amp.

You will be many times better getting a nice amp and some cheaper speakers. That way later when you want to get some nice speakers you already have the amp. Get an ADS or Alpine amp and you will be happy. The old school soundstream and orions ect. are great as well and for the price can't be beat them.

I would skip the 6x9 in the boxes, they will take up a lot of room and don't sound good through a seat. Get some nice dash/door speakers and you will be much happier.

For $300 you can get a nice setup.

$100 for am amp off ebay
$50 - $75 for a sub (the DIYMA is a real nice sub for the price)
$100 for the door speakers
$50 for wires, hook up stuff or if you need more for something.

Even if you went with the cheapest setup around you would not get lower than $200 for a full setup. the little extra you pay for some desent parts is WELL made up for.

I find Sony's stuff pretty quality, and I like most of it, their subs aren't the best but oh well... I dont know If I could fit 6.5" rounds in my door, do you? cause I heard sometimes it s with the windows rolling down and whatnot... Also I have a 8" sub from radioshack I got for free (Hmm I wonder why!) that I thought about building into a box with the 6x9's for behind my seat, and I thought when I build the box I could make it big enough to put a 10" in later if I wanted. Allthough I heard I can get just as much bass out of two amped 6x9's as I can an 8" sub, the mach 460 system in my cousins stang proved that to me haha.. I was also looking at an MTX sub, or a JL Audio sub... I'm not for sure but Isn't Alpine affiliated with JL Audio & Polk Speakers? :bigok: My cousin also told me I misewell invest in a good 4 channel amp while I'm at it too. :D

i have 2 audiobahn 12's and all infinity door speakers and a ma audio 1600 watt 2 channel amp to my subs and a 500 watt 4 channel alpine amp to my infinity's

quick question this is offtopic sorry (but it might help?)
i got a 4channel amp. got 4 speakers and 12'' sub.

figure i could run the back 2 speakers and sub on the amp

then the front two speakers i could just connect to the headunit? would that sound bad? or not as loud? i could really use not buying another amp here...

I use some 6.5" in my 2000 4runner but that is a 3rd gen. You would have to ask someone with a 2nd gen what will fit in there as i don't have a clue. With a spacer most doors can fit at least a 5.25 if not a 6.5 though.

As i said before, for now just get some speakers if you want to go cheap, skimp on them. But get a GOOD amp, a good amp can make junk speakers sound ok. i know, that is what iam using right now (got some cheap EFx speakers and that nice ADS amp, those things will SING!). Although the speakers make a big differnce too when you are first setting up your system you are much better off getting good HU and amps rather than speakers. The speakers are easy to change out later. The amps and HU are not.

For amps look at those brands i posted above. I can get some links if you want them. The old school stuff is BY FAR the best rought to take when wanting a system on a budget. You get %90 of the performance of the best amps today for %10 the cost.

You can make 6x9's sound ok, the problem is that i assume that they will be placed behind the seat, this makes them useless. The 460 in the mustang is setup with them in the open. Behind a seat only the bass will get through. Making them pointless. you would be much better off with a sub. As for brand, the IDQ subs are one of the best you can get for the price. They only run about $100 for the older v2. The new v3's are better but cost more.

Don't get JL, they are WAY overpriced. The only ones that are any good anyways is the W6 or W7 series. And there is no way you are fitting one of those in there.


Basicly, spend the $$ on am Amp and HU now and get some nice speakers later when you can afford it. A good amp can even make stock speakers sound totally differnt. Oh, and the channels for the amp is not that big of a deal really. a 4 channel is a good mix that allows you to have flexibilty. 6 channels are even better (which is what most of the ADS amps are) but in a pinch a GOOD (key word) 2 channel would work.

I would run the front 2 speakers and the sub off teh amp personally. The rear speakers don't do much for the driver other than fill in. So they won't matter as much, the fronts is what you hear though.

Just make sure that you hook up the sub right, you don't want to blow it or the amp. You will want to bridge the 3 and 4 channels to the sub and use the 1 and 2 for the fronts. depending on what kind of amp/sub and power it has that should work ok. Ideal would be to either get a 6 channel or another mono amp for the sub but you can make it work with what you have. The quality of the amp will play a big part in it running the sub well though.

Well heres what I've got for speakers...

2 Alpine 4" Round Speakers (Installed in dash)
2 Sony Xplod 6x9's
2 Sony Xplod 6.5" Round Speakers
1 Pyle 1400 Watt Amp (Bought at garage sale for 5$, Dunno if it works or how good, but it IS a 4 channel..)

I want to hook all that up, but should I bother with that crappy amp for the time being? Or should I run it all off the head unit until I get an amp? I'm sorta a broke highschool kid with no job for the time being... :( I just need to find out if those speakers will fit into my doors, BTW I DONT have the wing windows in my doors since that makes a difference...

I will refrane from any comments about the sony's.......

As for everything else. With that stuff try the amp, if it works hook it up just so that you will have on the wires ran and ready for a real amp later on. It is NOT 1400 watts i can tell you that right now though. Maybe 1400w MAX but only a few hundred RMS tops. Just be sure to use some good cables/wires when hooking it up. and leave a fair amount of slack so when you get something desent you can use all those wires and just change out the parts (running the wires is the hardest part).

I would still forget the 6x9's if i were you. Sell them and get a sub. from behind the seat they will not sound good at all and if you try to cross them over on a low pass they will blow. So they are really usless no matter what you do.

As for the door speakers, see if the 6.5 will fit, they should with a little work.

but sell the 6x9's and use the $$ to get a sub. You should come out about even. and it will sound much better and be simpler to install.

If the amp doesn't work then you have no choice but to run them off the HU but you really should get am amp of some kind. they can be had for under $100 for a nice one, well worth the $$

I know the amp ISNT 1400 watts but its better than nothin, I'm still gonna do the 6x9's cause I really don't think I need a sub, or want one that much, If I was gonna get one I'd get a cheap Sony one from walmart for like 60$ and call it good.

Although I suppose I could run the door speakers, the dash speakers, and that sub, cause I DO have a 50$ gift card to walmart that I need to blow! :hillbill: for that set up could I use like a 2 channel amp? or would that overwork it?-thanks for the help BTW
