Goodwill $17.99 purchase – 12″ Q Logic

Thanks Suzuki! I finally took out the driver and it looks like a dual coil but the leads to the speaker have been soldered so it might just be a single coil? I shoe goo’d the foam tears and it sealed nicely and flexes pretty well surprisingly with finger pushes. I might have some free goodies (amp(s)) coming my way to test it soon so I’ll give you an update. However, even if a monoblock class D amp finds me, I’ll probably keep my setup at 4 ohms sealed. You brought me into another avenue of reading with 2 and more, pushing a 1ohm sub. Much to learn.

So happy you supported me with the car audio stuff. I’ve actually taken a lot of what I’ve learned reading about car audio, which is vast, into my home audio setup. The sky is the limit without spending boat loads of cash on a good soundstage. This goodwill single coil Lanzar is a wuss below 65Hz btw, but after sealing up the 3 foam tears with shoe goo and hooking up a 150w amp then tuning my entire system (this was key), it’s actually not too bad! The position of the enclosure was tough to figure out. It unfortunately sounds best dead center of my trunk. It’s my first sealed box, so maybe the box design is just a pile of poop to begin with. I had a problem with my front door speakers putting out an even sound because they’re at my lower legs, so I put more emphasis toward the front on my HU, turned up the gain on the sub amp, set the parametric equalizer settings on the HU by taste and things are working out for now.

Today I got a 4 gauge KnuKonceptz install kit and it’s going to open up doors for the best aftermarket audio in my beater I’ve had. Planning a two amp setup and most importantly, making sure everything in the trunk is mounted properly and looks nice, indiscreetly. I have to say that this hobby tickles my tit and makes me equally excited as shitting a nice clean log in the morning. This post is way too long.

The HU has low pass subwoofer settings, but JVC decided not to update their firmware on the model so using the “Subwoofer” setting as opposed to “Rear” puts little to no juice to the sub. The amp has a LPF setting restricted to 80hz. Little too low for my taste but oh well. The box is an old school style Q Logic “hatchback”, 1.25 c.ft with an old Lanzar 12. I’d imagine if I had a bigger box that’s tuned correctly, the sub would sound better. I’m holding off until I attempt the fix on that Power Acoustik amp that’s broken. I was able to get the part from PA thankfully. I’m taking your advice by yanking the board and re-soldering the correct way. Should be a fun project 🙂

I typically run my sub around 100-120hz. My first 2 10s I crossedover around 100-110. The ’93 Camry’s trunk almost encourages more bass since its ass is so large.
