Re: fiberglass enclosure

Oh, if you go into that area over there (similar to what I did) you should be able to get close, if not more. I thought you were going to mimic what Will did - there's no way he's got 1.25 in those enclosures.

So yeah, you should be fine if you get into the rest of the quarter panel area.

Re: fiberglass enclosure

Hey Matt, what amplifier do you suggest for my one sub. I need in between 250-500 rms at 4ohm. I had used a alpine mrp-500 before and was pleased with it but do you know any better ones. btw with these subs you hear no difference in sound from saying giving them 300 rms compared to 500 rms. Ive tried both and jl audio told me the same about them.

Yeah, 1.25 doesn't sound too big, but it is, lol. I had to go further out into my cargo area than I wanted to. Looking back, I probably should have just used a different woofer... oh well.

Honestly, power is power, so you don't need some top-dollar amplifier. What's your budget?

This is the same for all sub woofers and all speakers. Every time you double power, you only increase SPL by 3 decibels - that's not much. You wouldn't notice a difference between 300w and 500w.

Re: fiberglass enclosure

well I dont want to spend more than this one.

http://onlinecarstereo.com/CarAudio/..._MRP-M500.aspx

ive had this one before but sold it on ebay awhile back because I wanted to get a more powerful one. The more powerful one sounded the same as the alpine so it was kind of a waste of time and money, like you said it only increases 3db. That alpine one is pretty small too.

btw, if you make it wider than farther out, its still increases the space to make it sound right,,,, right?

Save 40 bucks with this one - but this and the Alpine is about the best you're going to do <$200... unless you purchase used.

Correct; Space is space in this case.

Re: fiberglass enclosure

i think i might just build a box out of some wood I have left over from a box I built previously. Something like this that fits exactly against the back seat in the cargo area. I mean it will probably be better than fiberglass because it will take up the same amount of space since I will make it flush to the back seat and will be alot easier to build. What do you think matt? It will be like this except just one sub.

Re: fiberglass enclosure

That's what I did for my first enclosure (see 'WK 10" enclosure' link in my sig).

Wood is much easier to work with, and if you did it flush with the seats, floor, and side panel, it will look great!!

I'm torn between a few different ideas.

1) Remove the floor and rebuild it (flat! - I hate how it ramps up!). Build a new enclosure (from wood) - similar to the 10" enclosure I made, but instead of all the way across, it'd only be about 1/3 across, come out a little further, and go up a little higher (to fit a 12" woofer). Make a vented false floor cubby for the amplifier, and then make a few move removed top slots for tire iron, jack, straps, jump cables, other random crap. I'd also build the enclosure down into the floor (to get airspace, and then have a cover for that area, so if I wanted to remove the enclosure, I could cover that part of the floor and make it flat.

2) Leave the floor as is. Cut the fiberglass enclosure in half (so I keep the mold) and make it much skinnier (using a thin woofer - Dayton Audio just released a line of thin woofers, I'd use the 12" version ($150).

3) Something else, LOL

It'll be a good spring project for me.

Re: fiberglass enclosure

ah i c, I ended up cutting a box in half that I had (logic box). It originally held two 12" inch subs. I cut it in half to just use one sub because the angle of the back of the box is exactly the angle of my back seats. So its flush with it. Like what you said it only takes up 1/3rd of the space and doesnt go all the way across.

One question though, I am going to put the amp of the side of the enclosure. I see alot of people do this and most installers do this as well. I am wondering how should I secure the amp to the enclosure, does it matter that the screws go threw the box and into the inside of the actual enclosure?

Re: fiberglass enclosure

also do you have any tips for screwing the actual sub into the box. Ive noticed that when I screw it in, its not as secure as I would like. How do you usually put the sub into the box?
