Any Suggestions On This System

[DCR]

I am have not done anything with car audio since the mid ‘80s, so please forgive my ignorance. I wanted a critique of the audio system I am planning for my ’79 Z28 that I am restoring. Here is the list of what I have.

1 pair JBL GT102 subwoofers

100 watt Alphasonik amp

50 watt Alphasonik amp

1 pair JBL GT616 6-1/2 component speaker system

Here are the criteria:

I don’t want to cut any sheet metal

I want the system to be somewhat sympathetic to the time period of the car, so no trunk full of amps with neon lights and subwoofer enclosures.

No enclosures don’t want the extra weight plus I wouldn’t be able to put the T-tops in the

Trunk

Here is the plan:

6-1/2 component system in the doors, powered by the 50 watt amp, with the tweeter either on the upper part of the door panel or on top of the dash.

Here is the part that may seem a little weird. I am going to mount the subwoofer (infinite Baffle) under the rear deck with some adapters and fire them through the 6x9 holes In the rear deck, and hook them up with a pair of P25T JBL tweeters, so I will have full range sound from the rear deck, and I hoping for superior sound compared to multi-driver speakers.

The questions that I know enough to ask are:

The rear the woofer can handle 130 watts rms the tweeters can only handle 60, so how much power do I run, or is there something else I should do.

Capacitors where just coming out about the time I got out of car audio years ago, so I am not that familiar with them does this system need them and if so what, where and why.

Obviously this is a cheap budget system compared to what you guy’s on here would build, but any thoughts or suggestion would be greatly appreciated.

Caps are a no-no so don't worry about them.....I would look into getting more powerful amps 100 wats to subs won't cut it.

Thanks for the heads up on the caps. My subs are only rated at 130 watts rms so is really worth getting a different amp for thirty more watts, besides what about my tweeters they can only handle 60watts?

i like your thinking //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif caps are as he said a no go, your better off with a bigger battery. as for the infinite baffel on the rear deck, as long as you seal off the trunk from the cabin of the car the best you can it should work lovely.

and if you can get some pics of the equiptment from the 80's its always good to see the roots.

So are you wanting to run the sub and tweeters on the same amp?

That was my plan, but I am open to suggestions.

I think that it would be worth it to get another amp for the subs. That way you could at least give them each 100 rms. Or even upgrade to a 400 watt amp. Im sure they could take the extra beating. But I could be wrong

I should have specified the watts rating I posted were per channel, so the amp for the subs is 100watts per channel, and the subs are rated at 130watts rms each. They have an spl of 94 so it shouldn't take alot power to exceed what my 45year old ears can handle.
