[QUOTE="JKuhnz, post: 8044517, member: 651510"] Hello everyone! I'm new to this forum and hope some of you might be able to help me out! I currently have an underpowered amplifier I am looking to replace. I run 2 amps in my car, one is a 4 channel 760W pioneer amp to power the door speakers and the other is an 800 watt 2 channel Lanzar amp to power the subwoofers. I had them installed by an installation company. They have 4 gauge wiring running from the battery to a distribution block, then they have 8 gauge wiring running from the distribution block to the 2 amps. I am planning on selling the Lanzar 800 watt amp and replacing it with this: Hifonics GLX1400.1D RMS Power Rating: 4 ohms: 500 watts x 1 chan. 2 ohms: 1000 watts x 1 chan. 1 ohm: 1400 watts x 1 chan. (I would have linked it but the forum would not let me post with a link) My first question is, do I have to replace the small piece of 8 gauge wiring running from the distribution block to the amp and up it to 4 gauge wiring? Or will it be fine just leaving it as 8 gauge? Generally I would assume I would have to replace the 4 gauge but I read somewhere on a site it saying 8 gauge coming from the distribution block is okay. Though I wanted to confirm this and not risk burning my system My second question is, would this amp be too much for my subwoofers? I currently have 2 12" Dual 4 Ohm CompVR Series Kicker Subwoofers. They are rated at 400 RMS 800 Max. I have them wired to 2 ohms. I read on a website that a good way to pick out an amplifiers power is to multiply the subs RMS by how many subs you have. 400x2 so it equals 800 for me. The site also said a good range to be in is 75-150% of your total RMS. .75x800= 600W min and 1.50x800=1200W Max. So according to this site.

I just wanted to confirm that the stratgy is correct, I don't want to purchase a 1400W amp and end up blowing my subwoofers. Your input would be much appreciated! [/QUOTE]
