I am currenly doing a new install and was thinking of an idea. I have 2 10" subs in boxes in my trunk run by a mono amp on a shelf I built above the sub boxes...also on the same 'shelf' is a 4-ch amp for my inside speakers, a capacitor, and a fused distro block. This shelf takes up almost no room b/c it is on top of the sub boxes. To save space at times when I need it...I can take out my boxes and the shelf in a matter of minutes, but this leaves me with no sound( due to the 4-ch being removed.)
My idea:
To rig up switches between my HU and the speakers so that I can turn on the speakers by using the HU's internal amp...I was also thinking that I would need to place diodes inline between the switch and the speaker so that when my 4-ch is on no current will be going backwards to my switch. Will this work? Is it a good idea?
Some questions?
Do diodes have a resistance? Will it be too much for what I want to do?
Will I need diodes on both the + and - leads?
Should I switch the - leads as well as the + leads?
Any help/suggestions/ideas are greatly appreciated
Thanks,
Matt
If i were to do something like that i would use a two pole double throw switch, this switch will have three pins one goes to the speakers which it will be the common , one goes tho HU and other goes to 4 ch. If you want you could switch both + and -, so one switch per wire. The way this switch works is in one position it be powered by HU and in the other by the 4 ch. Thre are usually only the two positions some may have the third which is the centre were it is OFF.
