Anyone try one of these cheap dsp's yet?

Because, it's absolutely terrible with ground loop noise and only has 10-eq bands per channel?

I had one in my Tacoma without any issues whatsoever, but when installed it in my 911 I couldn't get rid of the noises.

I just replaced my Bose amp with the JBL4806 so I killed two birds in one stone.

So I just looked at this amp. interesting. I have some questions. I'd rather use my punch 4x100 on my midbasses, I could use the other channels for my subs, tweets and widbands....could I use the high level out to high level in on my punch amp? basically turn the gain way down on 4 channels of the jbl and run into the high level of my punch amp.....or am i setting myself up for some major noise?

Here is another option from the motorcycle world, but a better name and some extra coin. Hertz – S8 DSP – Volunteer Audio

I'm feeding my subwoofer mono amp from a channel off the Amp/DSP, and did just that with the levels -- started at -50dB ended up at -15dB to match the volume it was at being fed directly from the HU.

I did encounter an issue with the subwoofers popping on power on after doing this, but running the signal through a line-out convertor solved the issue for me. YMMV. I just wired the channel to an RCA plug and fed it directly into the RCA input on the sub amp, I never tried the hi-level inputs on the sub amp which is probably how I should have fed it..

Seems integrated DSPs in amps is becoming more and more common. I got this one refurbed for only $199, it obvious no Helix but I've been pretty happy with the purchase.

You may not agree on what I prefer, but after all, it’s about what we each prefer in our system. I want front, rear, and sub hooked up to the inputs on the dsp so I do not need a bass knob and can control my sub volume with the control in the headunit. That’s how I prefer it. I also want the fader to work correctly with my head unit.

You get sub out with the Dayton. As for ground loop noise, I have heard of it but I haven't seen it.

I got mine with the controller for $165 and though I agree that more expensive dsps offer more, with the helix being top dawg, I chose to get one now that I can afford and plan on upgrading later. I'd rather have music while I save rather than save with no music.

But to each his own.

I saw that one yesterday too, i found on ebay for $499 shipped....but at that point I might as well get a helix? Thing is, alot of these units don't tick off all the boxes for me....the cerwin vega/diamond audio do tho though.

I know i get a sub out.....but I want a sub input too where i don't need a separate bass knob.....Just one of those things I've always hated....I prefer the sub level in the head unit. i've already go enough switches and buttons in the car as it is lol

Or I can get a Fosgate DSR1 for $269.99.......

I thought these were buggy, software issues, and pains to use. I just remember a lot of people that ran them always complained

KFXGUY said:

I just noticed the cerwin vega has a couple of new dsps and so does diamond audio. Looks like they are the same units just dressed different and the diamond audio is a little more expensive. These actually fit what I'm looking for in a dsp, just wondering if they are worth a poo for a budget unit in a budget system. (it looks like only the 6 channel is currently available but the 8 channel will be soon)

OP sounds like you are just going to have to take a leap of faith on this. I would just look for a place like a Crutchfield that has a very good/friendly return policy in case you dont like it. I dont know who has it for sale though. All things considered, I dont think it would be bad at all.

That I am not sure. I am using their integration harness on a Ford. From the DSR1 I am feeding 6 channels to an amp to do active 2 way front and rear fill plus 2 channels to a sub.

My biggest issue is the app. My gripes after using it for a few years:

• You can only tune in the app on your phone or tablet, no PC option. You can export the tune files and edit with Notepad, but I would only do that after you get a decent tune and want to get it perfect. Reference: Why isn't there more fuss about the DSR1?
• You can't type in settings, you have to use buttons to move around frequency bands, gain, Q, etc. It's VERY time consuming. You cannot get the exact Q and frequency values you want. If you want more granular frequency adjustments, you need to move an adjacent frequency band close to it first. If I am doing a whole new tune from REW, it takes me 30min on my phone sitting in the car tapping buttons like a moron to enter everything.
• Gain increment is 0.5
• Max Q is 10
• Q uses something non-standard to calculate. If you export from REW, you cannot use generic or the Q values will all be wrong. Reference: Why isn't there more fuss about the DSR1? You can also use the profile for a Crown USM-810. It used to do the wrong Q values for higher frequencies, but I didn't find that the case (I compared Qs on the 3Sixty.3 setting and USM-810 and found no differences in the latest version of REW). With that said, neither of those REW settings let you keep crossover filters. So, you need to do all of your work with generic and then when tuned, change the EQ setting to one of those profiles to get your EQ settings. Neither one is perfect though for the DSR-1. The DSR-1 has more bands than either and the max Q is 10 (USM is 35, 3.Sixty is 6).
• Bluetooth connection is finicky

Overall, the SQ is fine and it works. For cars like newer Fords... your options are very limited and this is a nice single unit solution for OEM integration PLUS DSP. It was my first DSP, but I am done with it. It's too much of a PITA to set.

Thats exactly what I don't want. I want something simple. Basically i just want to be able to set my high and low frequency for each speaker and be done with it. I'll continue to use my head units time alignment. I don't desire all kinds of settings that I don't understand. I'm not that into this hobby and I'm not that picky. The DSP LP was cool and all, for the most part it was simple and did what i wanted, made noise unless i had a filter and drained my battery if I didn't drive the car for a week. If I disconnected power to the DSP LP then i lost all my settings so I had to leave it powered on.....yea...umm no.

I'm waiting to find one on amazon........ haha

dasupr3mek1ng said:

Bro you gotta choose what you can live with and without. From what you're saying seems like you need a Helix, Mosconi, the Focal FSP, something high end like that. Which translates to higher cost. Anything that I've found that has 6 in stats at around

I think ANS had a Focal FSP for 500 or so brand new in the classifieds. It has 8 in and out and the software is pretty simple in my opinion.

The axxess dsp also has 6 in and is 299 now on Walmart

If you're willing to wait you can get it for 235 on Sonic

Thanks! I have not seen this unit.....looks exactly like what I'm looking for. I just downloaded the app and read the destructions and looks simple and easy to use. If I got the vega or diamond, i'd be waiting on an app. This unit is only adjust with an app...not a deal breaker for me, but i'm going to see if i can use a spectrum analyzer with my mini laptop....if so, I'll probably end up getting this unit.

I had one of the Axxess lite but I needed 8 out so o switched to the Dayton.

I plan on keeping it until I can get a new Helix or Mosconi.

Yeah and Sonic has it for 250 it so but there's a wait. I didn't want to wait.

I got a Mosconi DSP 6to8 V8 I'd let go for 250.00 shipped.
