[QUOTE="Jeffdachef, post: 8240603, member: 650438"] my bad, i thought you only wanted 1 sub. That ppi amp aint gonna cut it if you want to run two hds300s. You should go for a single 15 hds300 or heck, even the HDC3 in a ported box instead so you dont have to stress too much on electricals. a lot more cone area and a lot less power needed to get loud along with adequate space for a proper ported enclosure. Dont buy some box off of ebay or some wack job shop that has no idea how to design a proper ported enclosure. YES go ported. Electrical upgrades - would need the big 3 upgrade done. A decent AGM battery under the hood and depending on your stock alternator size, if its under 80amps you might need a rebuilt higher amperage alternator. [/QUOTE]
