WRX Stereo Upgrade – 11/13

11/13  – Got everything going. Now it’s a matter of tuning it. I built my custom 6.5 woofer for under the seat for mid-bass

I rewired the back again a second time, moving the ground to UNDER the left seat with a better connector. Then moved the speaker wire down the left side.

 

BEFORE

Stocky tiny speaker/sub. 80 watt amp. Goal was to replace it with a 6.5 midbass woofer.

 

 

AFTER

$20 6.5 woofer, $10 spacers, $10 speaker tape. It rattles the seat it’s under. haha. $10 dremel grinder.

 

11/8 – Got a better Dremal Metal cutting disc and this time instead of 10 that just blew apart, I was able to cut the whole OEM sub box to fit a new 6.5 mid bass.

Tried to drill a circle, didn’t work. So did the above.

 

I learned how to test my battery. Looks like it’s doing fine 14.4v.

I lost the bass for 2 days only to discover I had loosened the speaker wire and 1 fell out.

My current goal is to splice the OEM subwoofer into a LINE OUT item, then to the RCA inputs of the mono amp. Then somehow tune it for 4 types of speakers.

11/6 – Finally got all the missing parts to hook up the subwoofer and amp. I’ve also started to pull apart my OLD OEM AMP/SUB combo to replace it with a 6.5 Mid-Bass speaker. Right now I’m just waiting for a metal cutting blade for a Dremel to cut the hole bigger.

I have a really raw setup right now. The amp isn’t mounted to the floor and the cables need to be routed through the middle console (PULL UP MIDDLE CONSOLE). Right now I was first wanting to get the sub going, THEN create my mid-bass speaker and wire that amp to the new subwoofer amp.

Also I’m messing around with the amp setup. I have no idea what i’m doing so I have to learn everyday and mess with all the complicated as f settings on my 2005 Alpine 9855 head unit. Right now it’s kinda like it sounds like TWEETERS + BASS. Nothing in between. I think when I’m done adding the mid-bass it will sound better but I might have to get a $162 Alpine Type R Component set for the front doors.

I’m learning ALL of this. I’ve spent 10 hours of research. I’ve never done any of this. I also keep finding I’m missing tools.

Crappy ground wire that I need to improve the end to.
Came in through firewall hole above the pedals (for power)

Back seat removed + ground wire, amp under the seat

Now I need to find speakers/install kit.

ORIGINAL

My car is 16 years old now and back in 2004/2005 I had bought a $500 stereo for it. But the fuckers didn’t even give me the remote for it and as far as I can tell never configured it. I changed 1 setting on my stereo that has been wrong for 16 years and suddenly my stereo sounded way better. I guess I’ve been incredibly lazy about improving it. So I’ve spent 10+ hours researching on what to do. Finally I was led to this forum of posts from 2003/2004 about people upgrading their stereos.

  • I purchased a set of speaker spacers and some foam backing.
  • For starters I think I’m just going to replace the front speakers. The back ones from what I can tell are useless even when upgraded.
  • I discovered there’s two prebuilt speaker holes in the back deck if I wanted to put in some 6×9 speakers.
  • I should probably spend about $300 on an amp and a sub. I don’t know. We’ll see.

I’ll post my findings here if anyone is interested or who has stereo experience.

I THINK I purchased the premium sound upgrade which might mean I have better than stock speakers, but still kinda sucky. I have no idea. I have this shitty stock 6-8″ subwoofer under my seat. It works a little but not much.

HERE is a link to all my research
