I have a PA demon 4 channel 2400watts amp. Will that sound good? Or do I have to by a monoblock?

to respond to the original post

start off with 2 pairs of 6 1/2 coaxials instead of the pro audio speakers

a single 4 ohm voice coil subwoofer to match the bridged power out of the PA amplifier

and this should yield a good sound with a small budget

dont buy a cheap deck get one with some built in processing
most pioneer's with the 3 band parametric eq would be sufficient to start off with make sure the deck does 4 volts out and not 2

you can build on this at a later stage by adding a separate amp for the sub and retaining the 4 channel for the mids
from then you can decide if you need to upgrade the existing mids or if they are sufficient for the sound you expect from the system

Didnt read through everything but I see fuzz piping some new pioneer decks for $1200.00. At a glance they looked good for a starter system.

my bad, $1295.00. I didnt check to see if they have built in xovers but everything else looks good for a starter system.

Yep, no argument there. For car audio, one man's meat is another man's poison. I can't begin to count the amount of times I've been asked if a particular system sounds good, when to me it sounds like something's seriously wrong with it, or something must be seriously wrong with the owner's hearing.

Still, there's some basic stuff that can be done to make the best of what we're given to work with.

This is why you never mention *tweeter that cannot be named*

Shouldn't be a big deal if it doesn't have the xovers on the HU. Most amplifiers have xovers built in that should suffice.

I bought two pairs of 6.5" Orion Cobalt and a 12" JBL sub in box with a monoblock

I have a question reguarding that, seeing as most amps have on-board xovers, why the need in most systems for external ones?

More of a want than a need. The external xovers may offer more flexibility, but quite often the end user doesn't require it.

I prefer have some sort of flexibility with tuning & making adjustments via the head unit while on the go rather than having to pull over & adjust the hpf, lpf or all pass filters on an amp.
Xover slope is another factor as well, HU + Amp = better slope or different slopes at different points for better tuning.

good to see that d OP went d car speakers way & not d usual trini 2 M&Ms & ah pioneer sub

i agree with jack , i myself rather use d deck's xover convenience rather than go fiddle in d back but imo once u spend d time to set up & tune ur system there is really no need to be fiddling around with it

also yes some crossovers have more adjustable freqs & slopes than ur deck , i find for most simple daily systems that uses car speakers : d deck xover & eq is good enough ...

Are xover settings something you adjust that often?

Was thinking the same thing... Once your xover points are set properly,there should not be a need to tune on the go.

Using multiple crossovers on HU and amp and passive all together will cause massive phasing issues and increased overall THD.

My amps lame, they don't have any onboard crossovers. :cry:

Postby **nervewrecker** » March 8th, 2012, 9:11 am

Depending on what I listen to & how loud, I shift xover points on the mid & mid bass. If I am home & just looking to make some noise in the garage I shift the xover oint from 63 to 125 so I can turn up a bit more without having to worry about distortion issues.
I sometimes have to turn down the bass on some of the modded tunes & sometimes switch off the bass altogether in traffic & set the door speakers to full range with the loud feature on mid for a bit of a thump. A few times I have gotten in trouble for the bass in the car park here at work so I kill the subs & use the door speakers.

Postby **- Rovin's car audio -** » March 8th, 2012, 9:54 am

me ? - nope , like i already said in my post above once i know d xover points on d equipment i using & i tune my system i never fiddle with d xover points once i set it

there are some ppl though for whatever reason like to fiddle with theirs ...

Sounds like you need a DSP that can store multiple settings.
