A little bass please... (not a fishing thread)

So here I am in a $100+K motorhome and I have no real bass for music or movies.

The in dash stereo has the two Jensen speakers which are actually pretty high quality, but they are small and turning on the "LOUD" setting with reasonable volume causes them to break up.

Then we have the Execu-crap home theatre system. These things shouldn't have been allowed to pass customs for being so crappy, but I digress.

The Execu-crap comes with a little gray sub that sits by the door. Turns out it's a 20W (20 ?!?!) sub that I can't even hear.

So my solution... The Infinity Basslink 200W powered subwoofer ($178 at Amazon). It's just a little bigger than the gray box.

I wired it to receive signals from both the DVD and the in dash stereo. I turned off the "LOUD" on the in-dash so now the Jensens are only doing mids/highs and they sound slick. The sub also has an auto-on feature so it only lights up when either the stereo or the DVD player is on. The black "feet" screw into the floor, so it's not moving. I ran 12V from the coach batteries and life is good.

I've got one of the MagnaDyne M9900 units upfront. The unit has speaker wires for left & right rears that are unused and the Infinity Basslink has inputs that will accept "line output" from a stereo (and/or RCA).

So I just pulled the in dash unit out and connected the left/right rears to the subwoofer. The sub came with wires that were plenty long and I just hid them under the carpet along the wall next to the passenger seat.

The theatre was even easier. I reused the wires that had run to the 20W unpowered sub.

It took about 4 hours total, but I had my son "helping" (He's 4)

this sounds like a great idea as I also think that the executive system is junk, as they had to replace mine already

I have a couple of questions

Did you run a remote turn on wire from your amp to your in dash radio along with the RCA plugs?

Did you just use the same wires from your executive sub to the new one? Did you have to run any other wires?

How did you run your positive and negetive wires to your batteries? Did you drill straight down from your floor?

Any other wiring?

Tulsasteve,
Don't turn up the volume too much. That unit looks like it could blow the windows right out of the camper (lol)!!!

(Looks like a nice unit!)

I've got the dual pane windows, so I think I'm good :-)

- No remote turn on. The Infinity Basslink turns itself on/off when it senses a signal from either the head unit or the home theater.

- Reused the wires from the Exec sub.

- The location of the Exec sub is right next to the door. I drilled two holes under the sub and ran the 12V and ground into the compartment next to the door. The compartment already had wires running to the coach batteries so I just ran them thru there and attached them to batteries.

- Only other wire is the one to the remote bass level controller. I mounted the controller next to the passenger seat so my wife can adjust the bass while we drive.

One tip.. Make sure you have a long drill bit. I started the holes with a normal bit and then switched to the long one. The floor (at least in the Georgetown) is pretty thick with all the layers.

I had an 18 inch bit from another project, so I was all set.

The only reason I ask about the remote wire for the in dash stereo is, the manual I found online says that you need it for the RCA wires but not for the wires from your home theatre.

Do you still use the Executive home theatre that came with it?

That sub that came with it is a piece of junk, and should be used as a boat anchor

I ended up not using the RCAs or the "remote on". The in-dash unit had wires for 2 rear speakers that were unused. It's a 4x50W in dash and only the fronts were being used for the 2 Jensen speakers.

The Infinity Basslink has inputs from 4 "line level" sources, so I ran one to the wires from the Exec sub and 1 each from the rear left and rear right on the in dash unit (one is left over / extra)

So the in dash is sending the left/right rear signals and the sub is dumping everything but the lows. The exec is only sending the lows and they sound pretty good on the Basslink.

Replacing that whole entertainment system is on my long term todo list. I like that sub.

My speakers for the magnadyne dash unit were a pile of junk. You could not get it loud enough without distorting at freeway speeds. My wife would just tell me to turn it off it sounded so bad. I replaced the speakers with some Infinity 6x9s. They barely fit in the factory location but they sound great.

NICE! I have map lights in the same space as the Jensen speakers, so I didn't think about replacing them with 6x9s. The Jensen's sound great at highway speeds as long as I turn off the "LOUD" setting on the head unit, so no bass, but now the 200W Infinity covers the bass.

Not sure what make speakers are in my unit. All I know is that there are 8 of them in the ceiling. Is the setup in the Georgetown different?

My Georgetown has the speakers in the ceiling as well. They provide the surround sound for the home theater.

When I installed the Infinity Basslink, it added a subwoofer to the in dash stereo (previously it had only 2 small car stereo speakers and no sub woofer). It also replaced the 20 Watt unpowered sub-woofer that came with the home theater.
