I don't want to waste my time using my existing equipment only to have it be a half-assed build. I want to know what i need to upgrade and if i even need to upgrade existing equipment.

This is going in a Tacoma Dual Cab. I have the GB10, GB25, and GB60 sitting in boxes waiting to be installed but I want to do it right. GB10 in sails, GB25 in pods on A pillar, and GB60s in front doors. I currently have:
HU: Alpine Halo9 ILX-F309
JL Audio RD400/4
Phoenix Gold RX2 750.5
JL Audio twk88
JL Audio Jl audio 10" powerwedge+ subwoofer

I can have the PG power the 10s and 25s and bridge the JL Audio for the GB60s. Are these amps going to serve me well? Would i see a big difference from replacing these amps to a "good" 6 channel or 2+4 channel?

Is the TWK88 going to serve me well with these front three? Can it make these speakers be all they can be?


I don't want to spend money if i don't have to, but I have gone this far down the rabbit hole, I don't want to have any regrets.

The amps and processor will be fine with proper tuning. The only way you could improve things is it you went with a more powerful processor like a Helix. Again, proper tuning is key and of course proper install.

Is there a video or post that would explain why the helix is that much better than a twk88? Or if you could shed some light on that I’d really appreciate it. If you were in my shoes would you replace the amps and the dsp or just add a helix dsp and call it good? Again, thank you.

If you already own the JL dsp then use it and see if it makes you happy. Its a good piece that works.

The Helix has 30 bands of peq per channel with shelf and allpass filters. Plus all sorts of other goodies. Go to www.audiotec-fischer.com and download the software to see for yourself.

I liked the twk. Love the helix. My conditions were different though. 10 bands of peq weren't enough for my situation. Having so many on the helix is a dream. You always have many bands left over to use for mono tuning.

Well, I figured I went this far, why not go all the way?

Just ordered the Helix P SIX DSP MK2.

Now i have to learn how to use this dsp when i was finally getting a little used to the TUN. Going to have a lot of fun this weekend getting this set up.

If you are used to dsp's the helix software is super easy.

Some people dont like it but I dont understand why. It's very straight forward.

Eyes not being what they used to be plays a big part in that.

Checking out the demo, seems pretty good. I have been unable to find the input voltage, is that something i need to input somewhere in the dsp? Its 4v and it fits the requirements.

I did have a question regarding this dsp. Later down the road, if i were to upgrade, can I use the output on the dsp to go to a 4 channel amp as rear channels and use that for rear fill *and* sub? Sorry if that is a stupid question. If i can't perhaps i can use the halo9 to control rear fill or sub?

There's an input gain adjustment on the processor with a clipping LED. You set it and forget it. The processor won't let itself clip. You can defeat that feature but no reason why you'd want to.

If you want to run 3-way plus sub plus rears you'd need to upgrade to the Helix Pro or add a second processor and tap into the midrange outputs of the current processor. For proper rearfill you will want to run them around 350-4000 give or take a little on either end and delay 18-25ms depending on the install.

I just looked at the manual and it says "If this LED lights up reduce the input sensitivity by using the potentiometers until the LED goes out." How would i know which channels are clipping? Do i turn headunit up to 75% connect rcas to helix one input at a time and turn up sensitivity until clipping?

I wish this came with 10 channels but whatever. I was thinking using the halo9 to control the rear fill since i figured the sub was more important to have on the helix. The Halo9 has TA/crossover adjustments/ eq/etc.

Sorry OP... I was just about to pull the trigger on a TWK88 now i'm thinking twice about it. But then again I dont have the budget for Helix P SIX DSP MK2.

Sorry OP, how does the TWK88 compare to say HELIX DSP.3?

After extensive reading, for me, i would be doing a disservice to my audiofrogs if i didn't go helix. I have not set up the helix yet so i can't say for certain. I do have a twk 88 for sale though :p.

I got fantastic results with the twk using focal drivers. I couldnt get the same with the frogs for some reason and the helix helped a lot

I could never get my focals good enough in my truck with the twk88, then i figured i was going to upgrade at some point and said the hell with it. I LOVE having the dsp and amp in the same device, it will fit perfectly under my seat rather than back wall.

Very much looking forward to my first 3 way front stage.

Why would you use the HU DSP for anything if you’re using the Helix? I’m confused...LOL

Edit: Ok...rear fill. Since you have he TwK, use it for the rear fill and the Helix for everything else.

I am posting it this weekend when I install the helix.

What mid woofers are you using? Are you putting them in stock locations?
Since this was a budget build I’m thinking SI, maybe a GB690 or GS60. It’s going in a 2015 GMC Sierra, GB25 in the stock deck location and GB10 right next to it. Last truck I ran 8 batteries under the spare tire location and I don’t want to start doing big mod to this one.
