Just installed a pre-owned amp and Sub-woofer in trunk.. Advice on a smaller box..?

Hi
I just bought a two boston acoustic rally series subwoofers inside of a kicker sealed/ported box with kicker tweeters. The amp is a 1000W pyle 2/4ch also includes a SCOSCHE line converter.

My only "complaint" is it takes up a LOT of space (more than I thought when I agreed to buy it from another Cobalt owner) And since it's my 17 yo driving, he's going to have to know how to remove the speaker wires and the box in order to get to the spare and tools in the event of a flat.

I'm looking for opinions on using a smaller box, but candidly have no knowledge of how to determine the dimensions, porting, etc so that I could buy/build a wedge shaped box to avoid having to remove the box in the event of a flat.

Also, the installer used the battery terminals for both the positive and negative connections..and I'd always heard thats a BAD thing (but was in no place to argue)..and so should I move the negative to a frame bolt, or I am being overly cautious?

Thanks as always !!

The battery is the best place to ground, but in most cases (where the battery is up front) it is not cost effective. Look around for a smaller box at places like Best Buy. They usually have open items for cheap and will usually let you test fit it (at least we used to when I worked there). Good luck.

Just installed a sub box for my daughter last night. To address the spare tire issue, the back seats will be let down, and the box shoved forward enough for access. Is this a possibility for you?

i have a kicker L7 in a giant ported box in my trunk. its pretty big, and i cant takeit out of my trunk without taking the back seats completely out. if i even need my spare i can just take the carpet out and move the sub to one corner of the trunk. and have enough space to take the spare out.
If you cant do that and your really conerened about getting to the spare, just take it out and leave it in the trunk ontop of the carpet. strap it in with the cargo net so it wont go anywhere.
Bu if your son knows how to change a flat he should know how to fold down seats and push the box forward.
