Hi all,

I wanted to replace the Bose speakers in my '95 SE but keep the Bose amps for now until I get enough money for another amp. I currently have an aftermarket h/u with the NISAH4 radio replacement adapter wired to the Bose amps. I read in the mod FAQ that the Bose amps run at 1ohm therefore, 4ohm speakers, such as aftermarket ones, wouldn't work for it has too much resistance for the Bose amps to take. Question, has anyone tried this at all? Retain the Bose amps but use aftermarket speakers for front and back + amp and sub, all driven by an aftermarket h/u?

Thanks

 

The speakers itself on the 4th gens have the amp built in. Basically, each speaker is amped independently.

 

it can be done, all you have to do is change the speakers

 

MacAlert,

I realize that, each Bose speakers have its own amplifier. The issue is that the amp is rated for 1 ohm which is the resistance of the Bose speakers. If you use that very same amp to drive an aftermarket speaker, lets say an Infiniti Kappas Component set with separate mid and tweeter (4ohms), will that same amp handle them? The thread that I made reference to proves the fact that the Bose amp is made for 1 ohm load. Making it take more load is my concern, it might actually fry the Bose amp which I'd like to keep just in case I sell the car or something. I might not even get decent sound out of it. That's why I wanted to know from people, who have done this, what they had discovered from it.

2 Da Max,

I wish it is as simple as changing speakers but why change speakers when it won't sound good in the end?

I've dugged around more in the Audio and Electronics forum and found more info which explains that it might not be a good idea to do what I am planning on doing. Still, I started this thread to find out from those who have done the same if this is worth doing or not.

Thanks for your replies and hope more comes.

 

i mean you could do it for now, and later on you could always upgrade and do it a 100percent correct

 

Why dont you just rip out the adapter and amps, and run the aftermarket speakers directly off the headunit?

 

Because the factory head doesn't have a built in amplifier for the model car he has.....

 

That's what I'm planning to do now. Option #1: run the mids and highs off of the built-in 45w amp in the h/u and getting a JL500/1 to run my JL15w3. Option #2: get a JL450/4 and run the entire system and sub off of that. The difference is price, I'll be looking at least $700 for the 450/1 or $500 for the 500/1.

 

wtf, there are 2 2damaxes?

 

look at that one with spaces and the other w/o

 

your aftermarket headunit puts out just as much power as those amps.....

 

What amps... the JL Audio????

 

no the bose....buy a 500/1 and amp that jl sub and use your aftermarket deck to amp your internals....if u dont like how it sounds then u can save up for a bit then purchase a second amp to run the interior's

 

Thanks. I am leaning towards that right now.

 

Ok........so here's the scoop.

I'm going to run the Infinity speakers (front and back) with the h/u's built-in mosfet amp (45w/ch). This is a temporary thing.

For the low-end, I was going to initially get the Kicker KX700.5 from Don but I'm really strapped for cash right now. I was at an audio shop this morning looking around and saw the JBL BP300.1 (Power Series, mono block: 300w RMS @ 2ohms, 150w RMS @ 4ohms) on clearance. I couldn't pass this up so I ended up grabbing one for under $200 (tax and all). I read reviews on this amp on epinion.com and found out that this amp is underrated so I am convinced that this amp will handle my JL15w3. I was measuring around my trunk and realized that the sub-enclosure that the sub is in will not fit at all. Realizing that a custom-built box will cost me around another $350. I am going to put the JL15w3 aside (for future upgrades) and use my spare JBL 10" sub, rated at 600w, instead. It's in a 1 cu.ft. box. It's a very old model but was given to me years ago by my sister's ex-husband who worked for JBL. This is also a temporary thing until I'm able to get my friend in Vegas to build me a box for free when I visit him in a couple of weeks. I tell ya though, it pays to keep some of your old car audio gear.

Going back to topic:

I wanted to get some input before I start the audio upgrade tomorrow. I bought a set of Infinity Kappa Perfects 6.5 series from an org member. According to him, it fit his 4th gen Maxima. However, it was done by a shop who had sponsored his car for shows. So I figured that these speakers weren't a direct mount but I hope they are. I called Crutchfield and they told me that the speaker is about 1/4" too tall. Has anyone installed similar speakers in their 4th gen doors? Thanks.
