Speakers

Is it common to use 1 ohm speakers in other cars. I thought most speakers were 4 o 8 ohms?

As an OEM rule, there is no commonality... I've seen them use from 1/2-ohm all the way through 6, 12, and even 16 ohm speakers or speaker setups in different vehicles...

The 'standard' for aftermarket automotive is 4-ohms and home audio is 8-ohms. But then again that's just a starting point.

Dear Original Poster,

I just finished the install. With one minor slip up with the sub I received. Red was +, Black was -.

Either way, the writeup with associated photos worked like a charm. Even down to the comment about "Enjoy your mediocre sub"

Thanks!

My only guess, based on my research is if the OEM amp is Mono 1 Ohm and the OEM sub was a dual (two voice coils) 2 ohm and maybe it was bridged down so the sub would run at 1 ohm. My guess to why there are so many wiring combinations.

Mono/1-channel amplifiers that have two (2) sets of speaker outputs that are actually connected as one (1) inside the amplifier. What this means is that the 2 sets of different speaker outputs on the outside of the mono amplifier are actually only acting as one inside the amplifier (If you can understand, I'm sure you can!).

Just a guess.

I havent quite did the install yet still figuring out what to buy .... So far it looks like

Polk Audio DB461 - Dash
Polk Audio DB521 - Sound Bar

The reason im going with the Polks is
a. The specs match the OEM
b. They are certified for marine use
c. They seem to have good reviews

And all signs are pointing to the .....

Kicker - 10CVT652

.....Basically a 2010 version of the 2 Ohm 6.5 low profile Sub.

NONO!! For a TJ, get two pair of DB521's. Do NOT put 4x6's back in the dash...

In 2005, no mods necessary. The adapter can be had at any number of places. But I prefer to make my own. There's templates floating around.

I found another sub similiar in specs to the oem just not sure if it will fit in the center console. Hoping you all with experience can take a look at the size and let me know if you all think i can mod it in.

Sir G, great info on these posts, Thanks!

I just got my 03 rubicon about a month ago and am slowly cracking it open to see what was changed. The speakers have all sounded "small". Pulled off my front panels after reading this post and found 4" round alpines installed. Does the adapter you mention allow for 5 1/4 speakers in this front area?

Also, just cruious as I'm not an audio expert by any means...why no 4 X 6? Is 5 1/4 just a better speaker?

Thanks,
TC

Yes, and yes... Simply put, they fit. And the 5.25" size is a sweet spot for full-range speakers for powerful yet clean sound. You'll get a warmer, fuller sound than a 4x6 or 4" plate speaker.

Lining it with a layer of fiberglass can work wonders. Or at least some sound-material. (Dynamat). The goal is to make it more rigid and reduce pinging. The poor-man's route would be at least rubberized undercoating on the inside of the box. It's not great but better than nothing and will help reduce the pinging of the plastic box.
