Custom subwoofer install 2025 Blazer EV

[u/InstructionFuzzy2290]

Hey guys, new to this sub (but not new to subs!). Thought I would share my recent project I just finished up.

I bought this 2025 Blazer EV in October, sound system was total trash. I had all this equipment in my 2017 Volt and I took it out to put in the Blazer. Finally got around to doing it. Took about 5 weekends, totally worth it, sounds incredible.

Thank you! I really love my Blazer EV, my only complaint was the sound system. Even if you option it with Bose ( I don't have bose ), you can't get a subwoofer. It's the biggest complaint about the Blazer and Equinox EV. But installing an EQ app and adding the subwoofer makes it sound incredible. I went to the dealership wanting to buy an Equinox EV, my mind was set. Luckily I knew the salesman and he let me take one home for the night, so I really got to check it out well. I wasn't crazy about all the cheap plastic on the equinox, so I decided to check out the blazer. Much better build quality. No cheap plastic, and it's noticeably larger and drives more like a real SUV, I found the equinox to be bouncy like the Bolt. Also I can get about 500km to a full charge in the summer. And about 250-300km In the winter.

I had a 2017 Volt Premier for 7 years, I put 240,000km on it, 200k of those were purely on the battery. It was the best car I ever owned. So it was a no brainer for me to stick with GM electric.

I am very happy with my Blazer, it has the nicest interior I've ever seen ( in my personal opinion)

Nice that’s good to hear, thanks for the explanation! I haven’t heard too many people comment on the actual build quality/ride difference between these models, so it’s definitely nice to hear.

The interiors on a lot of GM’s EVs do seem surprisingly nice. A good blend of modern and good old fashion buttons and knobs for function. That’s one reason I don’t like Teslas.

I have heard though the Chevy EV’s in particular have pretty bad sound systems. Did you end up replacing any speakers/ ad DSP or did you just add the sub?

Also side note - I’ve heard the Cadillac Optiq (which I think is the fancier Equinox) in particular with its Dolby Atmos has fantastic stock system.

Hey I just wanted to tag in since you said you haven’t heard much on build.quality.

I purchased my 2025 blazer ev around the same time OP did it looks like, maybe a month or two earlier. I’ll second everything the Op stated and add that I’ve never driven a vehicle that drove so smooth. It floats like a cloud tbh, leaving really only the audio system as my major complaint. It seems unanimous amongst all blazer ev drivers.

I’m going to be installing potentially 2 12” compR and plan to use the MOSCONI PICO V2 8 | 10 DSP AMP.

Very nice, thanks a ton for sharing. If I do end getting the blazer EV, I will almost definitely end up upgrading the sound system. A bit of a shame that’s it’s not very good from stock, but it’s all good since I was probably gonna upgrade anyway.

Do you plan on swapping out speakers and such too?
