New owner looking for insight on adding a DSP

Hey all. First post, first time jeep owner looking for a little guidance. I recently totaled a dodge ram and had a new baby all within a week so priorities changed a bit... None of those priorities being car audio. I recently bought a 2014 limited with 5.0 uconnect and 10 speaker system. The vehicle will be here in a week.


Did a search and couldn't find much. Sorry if this is beating a dead horse....

I plan on running 3 way active front stage, some rear fill and subs. My first plan of attack is to install my helix dsp pro. Ultimately I would like to upgrade to the 8.4 screen, possibly after market head unit. Any pros and cons of either? Is hooking the helix to the 5.0 as easy as tapping a few speakers for a signal? This will be the most integrated system I've worked with so I'm just looking for a heads up on any issues I may run into.


For those who care. My equipment list...

Helix dsp pro
Dynaudio MW172. 8" woofers
HAT L4 carbons
HAT L1 pros
ZED Leviathan amps x 2
Stereo integrity MKIV 12" subs x 3
Rear fill speakers and amps are TBD.


Thanks in advance for any assistance

Ok.... Can anyone tell me which speakers to tap to get a full range signal? And I'm assuming I need to tap the outputs of the factory amp?

Greetings and welcome,

Nice equipment list. You should consider the HAT L8SE, they are amazing. As for the rear-fills consider going with a full range wide band speaker. You can setup as band-pass and zero to your sweet spot. The HAT L3V2 or step up to the L3SE. This way you maintain tonal balance thru out.

Yes, the Helix DSP Pro is a great choice for the setup you want. Both Audison and Masconi are working on new DSP unit ranging from 12 to 13 channels according to the rumor mills. Next year, the Helix is on my list to replace my 3.sixty.3.


As for summing, many options are available. It is best to sum the sub, front midbass and front tweeter to get the full 20-20k hz signal. Based upon your setup and level of equipment, I think it would be wise to spend money on the JL Audio Cleansweep setup. FYI: JL Audio is working on 2 new versions on which their is no date established yet. The first to replace the current model and the second with 8 channel output with full tuning capabilities. It could be possible they might move up to 10 channels to keep up with the market.

Best for now.

Re: New owner looking for insight on adding a DSP

Good info. Thanks for for that. I actually got rid of most of the equipment recently and "simplified" the install a bit to just a two way front, rear fill, sub, and still contemplating on running a center.

So the clean sweep "cleans up" factory EQ and flattens it? From there I would send signal to the helix? I always thought the clean sweep was just a fancy LOC. I will have to look into that. Thanks for the info

Greetings,

Yes, the cleansweep could be consider a fancy LOC. I like to call it a washing machine because it true cleans the signal and flattens it. When dealing with DSP in any nature, they work far more effectively when the receive the best input signal and you get the most optimization out of them as they were designed for.

If you are not used to a center channel speaker in a vehicle, then I would not bother. Unfortunately, the Alpine center is just a generic setting. To truly create a front stage, you need a better surround DSP and a tuning DSP. The delay setting is important to compensate for the wide center channel output. Currently the JBL MS-8 gives you a 7.1 setup, while the Alpine HXA-800 gives you a 5.1 set up. Both have lots of pros and cons.

Best for now.
