So at the moment

[Branch]

i have 2 600w subs running off my 400w monoblock amp
and 4 6" pioneer speakers running off just the head unit

do you think it would make much difference if i got the speakers hooked up to the amp as well?

or, should i use another amp for the subs and then use the monoblock for the speakers, as i'm not really happy with the bass coming from the subs at the moment.

Post up some specs or model numbers or even links to the gear you have, it will make our job easier when giving advice.

Generally, a "monoblock" amplifier is designed to run subwoofers only, and will only amplify sub-bass frequenices (20-200hz typically). This means if you hook your speakers up to it you'll only hear bass.

Okay mate, that's good help in iteslf
deck is a pioneer DEH-5750MP (coudln't find any useful links)
this is the amp i have: Ryda Car Audio - Clarion Car Audio APX1300 Mono Block Car Amplifier($149.20)
speakers: Pioneer TS-A1702C A-Series 6-1/2" component speaker systemFits in 6-1/2" or 6-3/4" openings at Crutchfield.com (front and back doors and tweeters in the front)
subs: http://img.photobucket.com/albums/v6...H/S4200122.jpg

Branch i have those splits in my car and i just blew one of them, they only run off the deck and still shit itself. Reakon an amp would make them blow easier or not?

[sweefu]

generally speaking feeding more power into them would only make them blow more easily, but a 50w rms isnt nothing, usually of a h/u your only getting something like 20ish rms watts.

Do you know what MODEL and IMPEDANCE your subs are?

Depending on their power rating you could probably add another monoblock amp to your system.

yeah but how much bass did you have going through them?

[Branch]

the model of the subs is PA12-S
they have 4ohms coils

I'd be more inclined not to run the speakers off the amp as they amp is not designed for full range. The amp only produces frequencies up to 20khz, whilst the speakers up to 31khz. But you should have the filter set up anyway for the sub, because you don't to be sending high frequencies to the sub, so really the speakers wouldn't be receiving more than around 120hz which are only bass notes.

p.s. Those subs are actually 300 watts RMS each.

[acarmody]

Perfect. Add a second APX1300 so you will have 300wrms at 4OHM going into each sub. May have to cut a hole into the other side of the sub-box and put a new wiring terminal in, but is easy as.

id get a 4x50w rms amp for the speakers. The speakers would only blow if sent a clipped signal, more likely to happen when running off the head unit. An amp should hopefully allow the sound to be loud enough for your liking without clipping the signal.

SPOT ON bezz..... i was waiting for someone to say this


Anyways yeah i'd get a smallish amp (50-80wrms) to run those front speakers, and set the high pass filter to around 70-80hz. You'll get a whole lot more volume from them that way.

Also 1991_Vn2nV, humans (with good hearing) can only hear to around 20khz.

In all honesty i would sell that monoblock and get yourself a high power version, monoblocks are designed to output the optimum power at low impedances, buying another 400w monoblock would only leave him with the option of running each one at 4 ohm, basically this means he'll only be giving the subs the same power, just using two monos putting out half power.

Get yourself a 800-1000wrms (at 2 ohm) monoblock, im sure you wont have any issues with bass then

thanks guys really good help
