car amplifier and stereo - advice please

[italianjob]

hello again

As part of my refit on t'bus I'm looking at fitting an amp + new speakers so I can here some tunes above the roar of the mighty 1.9DG in the back. Been looking at various threads and come up with the following plan of action:

new headunit (second hand), pref sony with sufficient outputs to run an amp - something old school like the F7750
new (second hand) 4 or 5 way amp running the rear speaker and 10" sub woofer
new speakers to suit - 2 up front in the doors and two in the rear overhead locker (I've got a Holdsworh Villa 3)

Now the technical bit - should I run the headunit and amp off the leisure battery with an inline swith for the amp so it doesn't drain the battery? otherwise I was planning on running the headunit from the main battery and the amp from the leisure battery and rely solely on the remote link between the two units to stop the amp draining the leisure battery.

Now, I'm not after the rave style bangin tunes high octane gut wrenching vibration white finger type of set up - 'no no no' as Cleveland would say . I'm just after something that I can here above the roar of the engine.

As always, any advice will be read with great interest

ta for now

Hi

I have a 1984 Holdworth. I am just finishing my stereo install.

First of all if you planning to fit Amps make sure you have enough power. I have 2 amps and subs & my Alternator can’t keep up with the drain. I am uprating to 90 amp Altenator this week or next.

I got a mine hooked directly off my Leisure battery via a fused distribution block. Everything is fused and insulated. I felt it’s the only way to get as much stuff off the starter battery. I have an intelligent split charger, though system not working correctly due to my lack of Alternator power as above.

I brought 6x9 speaker boxes and mounted them under the rear storage compartments. It all sounds great, but until the new alternator goes on. I am not getting too much oppo to really drive the sounds, without killing my Leisure!

what he said..
But with most heads now kicking out 50 watt standard with a dedicated sub channel add a little 12ins sub, pioneer 2way 6's in the door and kenwood 3way 69's at the back..

that's a big enough sound for me and the 45 alternator copes very well

I think most head units only really kick out 30RMS if you are lucky.
