Custom Subwoofer Enclosure and Amp Installed

[BimmerNoob]

did you look at the MTX TT6510-02 Thunder Thin 10" 2 Ohm Subwoofer


I think i can get a deal on these from a local stereo wearhouse... maybe $300 for amp & sub....
The amp i was looking at was a Hifonics Zeus ZXI 1010
2 x 250 W @ 4 Ω
2 x 500 W @ 2 Ω
1 x 1000 W @ 4 Ω


Thanks for the input

My MTX JH300 Car Audio Amplifiers - JackHammer JH300 | MTX Audio(paid $89, guy happened to be selling it locally when I was visiting family in Seattle) amp is only 2ohm stable and the Kicker L5 8" (paid $99 for mine, but Ive seen the 08+ version for as low as $75) I got is a 4ohm dual voicecoil sub, so they're both a perfect match being 300RMS/600Peak when pulled down to 2ohms.

I looked at a lot of thin subwoofers, but after doing vague searches on opinions using Google, they just seem to not quite hit the same deep notes a normal woofer can, which makes sense since they have limited excursion. If staying w/ the size of the box that ZeroChief created, a thin isn't the only option. Essam's box doesn't have the complex cuts and depth, so a 10" thin woofer might be the only option unless someone goes down to an 8".

Well I gonna try out the the set up mentined before with the Zero box.
Unless I can find another sub at the stereo wearhouse tomorrow...

I'll buy equipment & install electronics tomorrow.
Build box & install sub friday...

I'll let you know how it goes...

Honestly, they all probably sound fine. As long as I can feel it, i'm happy.

My sub won't arrive till Tuesday, but I should probably start building the box in the meantime...maybe this weekend.

I was going to build a wood box, but thought I could never maximize the airspace that the factory plastic box has.

I measured the volume and I believe it was around .53~.55 cu ft so it was a perfect fit for an 8" woofer.

Cut the face of the box off, fit a piece of MDF to it, fiberglass'd it on, and bolted in the subwoofer.

Just did a quick and dirty job cause no one will ever see it.

I was so tempted to stuff a 10" woofer in there.. but it would have been choked.

Sounds great... hits harder than I ever thought an 8" would.

I highly recommend it!

You're lucky to have the stock sub enclosure to build from. I looked at the L7, but the L5's power rating matched my amp better, along w/ the L7 requiring more minimum airspace, so I couldn't really justify the $40 difference. I'm glad your happy w/ it, I'm hoping I'll be just as happy w/ mine. Have you played w/ polyfill at all in the past? I'm curious if I should even attempt it since I'm not exactly a stereo tuner, so I wouldn't know what it should or shouldn't sound like even if I did it.

Yea, I have polyfill in there.... makes the speaker think the box is bigger.

Plus it being plastic, it will help it from being tinny or vibrate alot.

I always use polyfill in my boxes. If I'm close to the proper volume, just a bit, if it's undersized, then alot more

Here's some good info: Ultimate Polyfill Subwoofer Enclosure Resource [audiojunkies]

Great link. So did you actually recalculate his dimension down to the size of our boxes to determine how much should be put in there? Looks like a certain amount helps out greatly, but if someone goes overboard, it actually makes things worse.

So you didn't actually make an enclosure, but instead you just mounted the woofer onto the removeable panel and let it kinda of be a freeair setup? Do you have pics of this? I think it's an interesting idea as long as you mildly seal up air leaks that go into the spare tirewell, etc.
