Setup Recommendations - GMC Sierra
Hey everyone.
I recently picked up a 2026 GMC Sierra (non-Bose). The stock stereo sucks. I thought about doing the GMC x Kicker sub but idk about paying $800 for a 200 watt RMS powered sub. So I went down the rabbit hole. Wanted to gather thoughts on the following setup (followed by the questions beneath the setup listed below)
Front: Alpine R2-S69C (component system)
Rear: Alpine R2-S65
Sub: JL Audio 12W3v3-4
DSP: JL Audio TWK 88 DSP
Speaker Amp: JL Audio RD400/4
Sub Amp: JL Audio JD1000/1
Sub Enclosure: Fox Audio 12” Vented Enclosure w Storage
Quick note - the reason I think the DSP is necessary is because the sound stage GM’s head unit puts out is trash. Its front heavy and while even if I swapped speakers + did nothing else it would be an improvement - I’m of the “buy once cry once” camp. I know there are better speakers than the Alpine R2’s, but I think they’re decent? And I’m basing it on what was available from crutchfield and fit the truck. If you make a different speaker recommendation, try to keep it in a similar price range :)
Questions:
- do I need a DSP that expensive? Is it overkill? I didn’t even know they existed - thank chat GPT for my ignorance.
- I’m going to likely pay to have it installed. I’ve installed a few subs, but never on a 2020+ vehicle. This thing is new and I’m not screwing anything up lol.
- if I go the DSP route, how much is tuning?
Any additional info is welcome and appreciated. Thanks!
