i have recently acquired a Scosche 500K Micro Farad and i have done some research on how to install it but my friend keeps telling me i have to add it in like another battery... what i found online was that you hook the cable from bat up to + on cap and then run the + to the amp and then the - on the cap is grounded and the - on the amp is grounded... now on the other hand my friend said the same for + but you take the negative from the amp connect it to the - on cap and then ground it i need to what way would work the best and which way is right please.... btw i do know how to charge it so im looking for that... thank you very much for whatever assistance i can receive before i have to go to class..
