I want more bass. What should I do?

[Rayher12]

This is definitely doable on a budget. I assume you do not want to rattle your windows, so I think your Kenwoods should suffice for your needs. You did not mention what model your Kenwoods are.

maybe not rattle the windows but move the mirrors for sure and maybe a little window rattle. I currently have a kenwood kac 511 and the subs are kenwood KFC-W120SVC

Honestly, 4-6-½'s might be your best option.

Those subs are perfect for that amp. Single 4ohms voice coil. Both subs paralleled is 2ohms, which sets the amp at 500 RMS. Only thing left to do is have your box built to manufacturer specifications. I personally prefer sealed boxes for simplicity, volume, and sub control. It is good practice to add a divider when subs share an enclosure. For deeper bass, a slot ported box is your best bet. Issue may be- space available, higher cost of extra material, and design. Consult your manual for box specifications.

While true, the issue is limited funds. He already owns those 12s so might as well give it a shot. If it is not enough bass, could always sell the boxed 12s to finance the 6.5s.

Are they shallow 12's? He only has 5-½" of mounting depth. I don't think that he will have any where near enough air space for two 12's behind the seat of a standard cab.

enough air space

He said 2.39 c.f. and 5.5 mounting depth. Subs are 5-7/8. So there is a 1/4 inch to contend with.

Yes, but 2.39 cubes isn't enough for two 12's, maybe one 12.

No they aren’t shallows atleast I don’t think but I just checked on the subs that I have. What the mounting depth is for that one and it says 5.8 inches

Those are too deep.

Those are too deep.

How about a spacer and a grille to protect it from the seat's back?

Let me clarify. I currently own two 12s and those 12s are the kenwood kfc-w12Osvc and the mounting depth is 5.8 inches.

Did you happen to find the recommended box size?

For which subs?

That is perfect! Sealed per sub can go as small as 0.75 c.f. and as big as 1.75 c.f. So any size box within those parameters you are set. You should take a good picture of that sheet, title it "KFC-120svc", and post it online. I found zero info on that model. And one website wanted c.c. info to let you see their specs sheet.
