anything is posable

[aris_unlimited]

^^ agreed. I would just check with some places that specialize in car audio, there is a guy around here that could do just about anything you want to a Z.

[fairlady Z]

yes.. probably... I hope!!

are you looking to take the bose woofer out and use the hole for your subwoofer? Are you going to replace/upgrade the head unit?

I don't know about the bose unit, but the non-bose did not have RCA outputs for an amplifier. I just bought a cheapee pioneer deck for like $150 and had an old free air kicker i put in the bose hole amps under the brace in the back. Power line was a PITA to run though. Sounds decent for an old beat down kicker sub and needing attention to the amp settings (i'm lazy). I would personally prefer the bose over aftermarket. Had a bose 7 speaker system in my Cadillac and loved it.

I want to take out the bose amp. and woofer to put an aftermaket amp. and woofer.I'll put the amp. behind the driver seat and I take out the spare tire for the two subwoofers.

I hope it will work!!!

Answers to your question.

Quote » Does the 350z come with a factory amplifier?

Yes. The Touring and Grand Touring models come with the Bose Sound System which consists of different speakers (mostly the ohm ratings are different), a special Bose Subwoofer, and a Bose Amplifier to supply power. The other trim levels do not come with an amplifier.

Where is the factory amp located?

On the Bose equipped 350Z’s, the amplifier is located in the far left trunk corner. If you pull up the carpet and spare tire cover, you will see it bolted to the floor.

Can I use the factory amp with aftermarket speakers?

This has been debated over the years on several forums, with no real clear answer. Bose uses a proprietary system that does not conform to industry standards. Typically the OHM rating on the Bose speakers is either much lower, or much higher than the industry standard 4ohms. The general consensus is that you should not use aftermarket speakers in conjunction with the Bose amp. It may work, but you run the risk of burning out either the speakers, the amp, or both.

Can I just replace the factory amp with an aftermarket one?

Yes and No. The Bose amplifier is wired much differently than other aftermarket amplifiers. It is possible to catch the input and output signals at the Bose amp, but wire splicing will be required. Power cables will also be required. Most aftermarket amplifiers will not fit in the OEM location.

How much power can the OEM wires handles?

I ran 75 watts RMS through the OEM wires for about a year. I never had any problems. For those that dont know, 75 watts RMS is ALOT of power for 6.5" component speakers. It is more power than the human ear can stand for any length of time. [/quote]source http://www.350z-tech.com/zwiki/Amplifiers_(FAQ)
