Re: Aftermarket speakers?

I have not gotten my alpine speakers yet but I did get the iawa and did a quick test. I haven't done a lot of adjusting (the iawa) has an equalizer but it sounded too boomy. But it also has this battery saver mode that cuts out the more energy consuming movements to the subwoofer and in that mode it sounded pretty good. It nearly doubles the battery time to boot. Out of the car in the house it sounds good in the normal mode. I think with the alpine it's gonna sound pretty good. Not as good as a full retrofit with amps and new head but way better than stock I'm more of a midbass myself and it could be a little better on that but maybe I need to fine adjust. In the car in this low energy mode I'm guessing I should get the 18 hour battery time for sure.

so after all this did it really improve anything?. from what I read around it was kind of a pointless upgrade as it did not improve anything. now if this was bose! and you can hear the bass ok. like my chevy bolt 2020 lt blows my lt2 spark out of the water when it comes to sound. i had no idea how miserable the spark is when it comes to fm radio or music in general :( sad

He stated it was a "definite improvement" and I have no doubt he's correct. The Spark EV was an experimental/test mule, which GM utilized their cheapest economy car body for the experiment. When cost cutting is the primary goal, expecting anything done better than bare minimum, is pretty much an unrealistic expectation.

The speaker sizes in the Spark are 4" and 4x6". Without substantial effort and cost to create an enclosure that will allow speakers to replicate lower frequencies (which would increase space, which usually defeats the purpose of a tiny speaker), a full range of sound/"good sound" is not achievable. The Bolt, even in the LT trim, has 6.5" speakers (i believe), which are already leaps and bounds better (all things being equal) than their 4" or 4x6" counterparts. Throw in the sub and tweeters in the bose setup (unsure of the tweeters are standard in the lt), and you have a recipe for a system that will produce what many people will consider, a good full range of sound, up to a certain volume level.

I've tried using the 5x7 rear speaker adapter posted in this thread, all the screw holes line up but it doesn't seem to have any holes for the 2 plastic posts (seen here https://www.youtube.com/watch?v=dHNYuntv00c&t=62s, they are right next to the two closest screws). Am I missing something?

Those are alignment dowels, only applicable to the original equipment. If I was installing speakers, I would cut them off flush (dude in the video simply bends them out of the way).

Addendum: Plastics tend to break when flexed too much when cold. When I'm disassembling plastics, I make sure to do it at room temperature.
