HELP installing a cabin speaker amp

Recommended Posts

ftlbs

I must preface this by warning everyone that I have very little experience with audio systems.

I own a 2009 Malibu Response FXi and I am trying to add an amplifier to my 4 Rockford Fosgate factory cabin speakers. The amplifier itself is already installed, but I'm having a hard time identifying the cabin speaker wires that I need to connect to the amp. The cabin speakers are currently wired and powered through the factory JBL black box that is found behind the passenger seat. Could any one tell me how to locate the correct speaker wires so I can wire them into the amp?

(FYI, the amp I am using for the cabin speakers is a Massive Audio: Nano Block N2 - 800W RMS Mono Block Amp. Is there any reason I should not use this amp for this application?)

Thanks in advance.

Sorry, but this is a subwoofer amp, and will not work for full range speakers. 

Speaker wire colors are standardized. You can google "car audio speaker wire colors" and you should find the for color pairs used. Also, google "jbl prospec black box manual"

If you take the black box off the mounting wall, there is a wiring diagram on the back of it. But as MLA said, a mono channel amp won’t work for the cabin speakers? 

Do you have a sub in the boat? If you do there are some really good five channel amps out there that can power the cabin speakers and sub. I added one in my response and it was a huge improvement.

That amp is a “mono” meaning 1 , or sometimes 2 channels, in this case the NX2 has 2 channels. It does noth have a full range built in crossover so you would have to buy one to get any useful sound out of your cabin speakers.

There are plenty of inexpensive 4ch amps with built in crossovers that will fit the needs of a 4 cabin speaker set up. Malibu was using this amp for cabin speakers during the early 2010’s

Rockford Fosgate R400-4D 400 Watt Full-Range Class-D 4-Channel Amplifier https://www.amazon.com/dp/B004T0WFVE/ref=cm_sw_r_cp_api_i_k5Q3CbH6D1X6M

im sure with some digging you can find the wiring diagram for the Jbl black box on the web (if it’s not on the back)or possibly in a thread here, but if it’s just the 4 speakers, I’d probably just get a flash light and see what’s plugged into each of the 4 speakers and note the colors.

Thanks for the help everyone. I will start saving some money for a different amp.

Quick question, would an Exile Javelin amp be overkill to power the 4 original Rockford Fosgate cabin speakers? I thought about saving for one of these amps so that I can have 1 amp to power the cabin speakers AND a subwoofer to be installed at a later date. Let me know your thoughts. Thanks for all the help.

That would be a fantastic amp if you add a sub! It would still be a very good amp for the four interiors but it is a five channel amp so you could add a sub and still have just one amp. Might be a little overkill if you aren’t going to add a sub.

Not overkill. It’s a pretty economical amp even without factoring in the 5th channel for the sub. If anything this gives him the option to add a sub at some point. I’m a big fan of “future proofing” like this. He’s going to all the trouble (labor) to install an amp... might as well have the option, right?

And a 10” sub would do wonders and be a Smaller enclosure.

That’s very true too. I’d just go all the way and add the sub too :)

I added a 10” sub in a sealed enclosure I got on eBay to our response under the driver and it was a big improvement too.

Even a good 4 chnl amp will drive 2 pair of in-boats and a mild woofer. Anywhere from 50W rms to the speakers and 200W to the woofer, up to 170W rms to the in-boats and 685W for a woofer. 

Id put a bit of thought into how much rumble you want in the future. This will help with the present amp selection.

Get the javi, an exile Xi12 and a qbomb box. It should fit easily under the helm. Best bang for your buck IMHO
