Component question

[2010 Infantry Vet]

My rockford T2652-S 6.5” component speakers are rated at 100 rms. I have a kicker KX650.4 amp 120 x 4 rms (birth sheet says 170 rms) powering them. Im only using two of the channels. Should i hook up two channels to the tweeters, and other two channels to the mid woofers? Or just leave it how it is? Other two channels are powering my rear rockford 6x9s. It screams as it is now, but i have seen a lot of you guys running theor own channel to each woofer and tweeter.
Let me know what you guys think.

More tuneable amplified seperately, but if you're happy with the sound there's no need to change it. If the tweeters are in the door and you're still planning on running your new amp for dash speakers I'd leave it as is. Kind of depends where all the speakers end up. You're not running a dsp as far as I know so you can't cap the high end on your speakers making it less worthwhile running active on your components if they're in the same location on the same axis such as both speakers in the door.

Now I see your tweeters are in the sail panel. If they're not too bright for you I stand by my previous assessment given your set up as I understand it

More I think about it, I will probably just leave everything the way it is, and hook up the rockford 100 rms x 2 amp to audio frog dash midranges once i get them.
I do not have a dsp, but my alpine has the ability to set each individual speakers frequency. But all of my speakers are ran by my amps, so I dont see how the radio setting the frequencies would actually be beneficial.

How many outputs does the Alpine have? A DSP will have six or more outputs each with the ability to be set to a certain set of frequencies. Each of those outputs would go to an amp channel and then to the appropriate speaker.

Did you get the Alpine installed?

Either way they are right here.... you need a DSP to pull this off... hell you probably should have one for the midranges too.

If it sounds great why fight city hall

Once you add the mids up front and listen to them you can make the amp cross over changes and head unit changes as need be to maximize the sound quality

If you want to run evererything Active down the road you can add a DSP at that time, The DSR1 can be used with high level inputs or straight from an aftermarket radio

it does not have to be an integration unit , But a DSP for $ 250.00 is not a bad option

The amplifiers have 1 crossover point and you're either playing above or below that point. DSP or if your new head unit can set the range you have 2 crossover points. On a subwoofer or tweeter this doesn't matter as they both operate on the extreme ends of the range. Mids and mid bass however run ideally in the middle between the 2 so it's nice to be able to cut out the low and highs that the speakers aren't made to play. This will make the speaker clearer as it isn't muddied by playing frequencies it can't reproduce, but will try to. My dsp also includes a 31 band eq per channel so I can raise and lower frequency bands independently on the same speaker. If I'm lacking at 600hz I can boost it. If it's too bright at 1900 I can cut it is basically the idea. Your alpine may have that ability as well, I'm just not familiar. Regardless, that's the benefit of a DSP. If it sounds good to your ear then none of this matters and nothing is an absolute neccesity. If mine sounded how I wanted and I was happy I wouldn't change a thing.

I havent installed the alpine radio yet, so i have no idea what it can and cant do. Here is what i found:

It looks like it has some form of DSP built in using their tun app like they have built into their top line amplifiers

The ability to play FLAC off a thumb drive is a feature I wish the factory unit had. That's a nice feature

I dont wven know what the hell a flac file is! Haha. Since all of my speakers are ran off of my amps, the alpine audio feature wouldnt work in my case, would it?

FLAC is a high quality lossless audio format. Way superior to MP3. The alpine would absolutely work to process sound since it supplies the source to the amp. For guys running dsp it's head unit to DSP to amplifier. For you since the dsp in built into the head unit you just skip the middle part.

I just watched the video and the built in processing is not quite a full DSP. It gives you some basic time alignment per channel (not per speaker). It only has six outputs (front, rear, sub, in pairs) so it will not give you the control that a DSP would. The equalizer (while nice) is more of an overall EQ and not a per channel one.

One very nice feature it has is an optical output. That means you can stay digital from the head unit to a stand alone DSP (Alpine 800, Audison Bit One, Helix, Mosconi, DSR-1, etc.). My recommendation is to pick up a real DSP before (or at the same time) that you try to add the midranges. Hell, I have a Bit One sitting here unused that you could pick up pretty cheaply. Since you would already have enough amp channels to go fully active a real DSP will give you complete control of each speaker.

How much would a bit one cost?

yikes, that Addison stuff is crazy , probably $ 1,000.00

DSR1 is the poor mans DSP, Thats why I got one ......... lol

 

[TomT]

The Bit One.1 is around $750 online. I was researching the optical out and it seems to use a proprietary plug (stupid Alpine) and from what I'm reading you would lose the chimes, etc. by going digital. Better to use the RCAs in that case.

Ok never mind! Lol! What is a decent DSP for the money? Im not into competitions, just looking for something to set the range for each speaker. So will the optical cable from my alpine radio to the DSP really make a difference over RCAs? I know the adaptors that use speaker level inputs from the factory 8.4 to convert to RCSs are not very clean sounding.

Seems this would be the way to go since im running an alpine X108U headunit. But $800 damn!!! $450 used on ebay
