overusing amp??
« on: Feb 1, 2006, 10:01AM »
hey guys,
this is kind of a stupid question cos i already think the answer will be yes, but ill ask anyway.

I have a pioneer 300w amp running a kenwood 12" sub in the boot of my car, and was wondering, if i connected my 6x9's to it as well, would it bake my amp? oh and btw, the amp is already bridged...

lol now that i have asked that, it sounds even more stupid.. but hey.. what ya gunna do..

peace

it will cook some thing, if the amp is only a 2ch, and its bridged, it will be running at 2ohm, add anything else to it and it will bring the amp down to 1ohm, and i dont know of any low end pioneer amps that will run 1ohm stable, same goes for the sub, and the speakers, in a nutshell, you will cook something

it is possible to run the two speakers off one channel and the sub off the other. you will need an rca splitter (2 female> 1 male) to connect both up. The speakers will run at 2ohm and in dual mono. while the sub will run with less power it will still work.
seems very dodgy. getting another amp would be an option. you asked if it was possible and i gave you the solution.

Rathies has the only option if it is just a 2 channel amp. And that's a very dodgy option.

However if it is a 4ch amp, it'll be fine.

Just run your 6x9s off the head unit if it's a 2ch.

You could hook the 6x9s up in series and then hook them up in parallel to the sub, bridged on the amp. They would be in mono though. However the resistance would be acceptable.

Hang on, you need to use a low pass filter for the sub, so unless you have a 4ch amp you can't do it.

well what i would say is are your 6x9's any good? cuz if they are why dont u give em 1 channel each and F*ck the sub off untill you get a more powerful amp to power it. The sound quality should improve and you should get enough bass from the 6x9's (if they are good 1's).

Ash, sorry to contradict you but he'd be better off just running the 6x9s off the HU and keeping the sub running off the amp. There's a lot of lower frequencies that 6x9s don't reproduce yet a sub will.

as long as you dont have a sony xplod sub then this is true. the cheap hexagon ones don't respond to anything under 500wrms.

Old Sony Xplod gear is aptly named... it has a tendency to eXplode.

The new stuff is alright though.

the new ones, like these: http://www.sony.com.au/xplod/catalog/product.jsp;jsessionid=LBBKVIDK55RAACWSCFBCFEQK0IIUGIV0?categoryId=22002, are the new series, they come in 2ch, 4ch and mono, and are all the exact same dimentions and shape, which, on a install level is excellent.

anywho, back on topic now

That's weird..My sony 6x9's sound awesome and i've heard some pioneer ones before and the bass from them was more of a high pitch crack than a shake and resonance sound, hard to explain.. put it this way, the sony's gave a lower frequency as i could feel it and hear it where the pioneers i just heard a tinny bass sound..

All depends on how it is run aswell...if one is amped and the other isnt...how good the amp in the headunit are, wiring correct and all sorts of things need to be taken into account.

Guys, you can actually use the one amp for both. Most 2ch amps will allow you to use them bridged (ie for a sub) and also in 2ch mode at the same time. I know my old crossfire amp could do that. As for the lower fequencies, yeah. You really do want to just be putting that through a sub without the highs, as it sounds really odd getting muffled high sounds from the boot :)  The amp wouldn't blow if you wired it correctly, and adding speakers doesn't always mean dropping the impedence, it depends how you wire them up.

All in all, it would be doable, but ineffective. Esp. seeing as generally 6x9's tend to interfere/cancel out bass from the sub & vice versa, unless you have a High Pass filter on the 6x9's so the most they produce is midbass.

Oh, and as a sidenote - sony car audio bites winky :)

meh im with josh here, i don't think sony stuff is at all crap, most people have  branded it shit because of the budget stuff u can buy at supercheap auto, but im sure if u spend ur money, u'll get what it's worth...Sony has been around the market for ages, i don't think they'd make crap  :-\

They might not make crap but i dont think they make the best gear on the market either.

All companys have there good and bad products (not bad but not the best) and car audio isnt sony's strongest point. There home theatre gear is awesome and they make some nice projectors and tv's.

Its also personal preference aswell...i wont put sony gear in my car (amps, speakers or subs) but ill have it all through my home without a second thought.

THe problem with sony is they dont make all there products in 1 place. Eg sony home audio makes there stuff in japan and china to the highest quality and sony car audio is mostly made in taiwon to um lesser standards. I dont want to start another fight like i did when i first joined with stick but from what i have heard is sony car is getting better and i hope it does cuz i am a sony fan when it comes to everything eles eg home audio, dvd and ps products.
