So i am starting a new build soon over my old Sundown audio sa8 v 1.75s (4 of them). So i am looking for some peoples input on my new system. The subs i am looking to change out for are 1. One Sundown audio z-4 18 $609.00 2. One SSA Zcon 18 $542.00 3. One SSA evil 18 $799.00 4. Four Sundown audio Sa-8's v.2 $740.00 5. Two Sundown audio X-15's $778.00 Just wondering what everyone thinks. Three of them are single 18's, so wondering if that is better then the 2 15's and the 4 8's. The car is a 2004 hyundai elantra gt HB ( my old build log) http://www.soundsolutionsaudio.com/forum/topic/52732-hyundai-elantra-hb/page-6?hl=holykaos Still have a few issues with the car, like trying to find a high output alt. Dc is the only one i have found and $700 is a little too much for me so i think i am going to remove my ac pump(Ac went out at the start of the summer) and make a bracket for a 300am alt. from mec-man and just have 2( the factory one for the car and a larger one for the batts). Not sure how to work the 2 Alts. like that but i can figure it out. Let me know what you guys think. Re: Added prices from ssa store.
