I am using mine with 8 awg wire and it runs perfect. I am not running it at max gain though. Only using it to run one 10" L7! **Q: Does this amp have an auto turn on feature so I dont have to wire up a remote turn on?** A: Another option in which I chose since it does need turn on signal is to use an added retained accessory power relay or just a simple relay. Your going to remove side panels to run RCA anyway so tap easily into a 12v power source when vehicle acc is on which can be found closest to amp position that is passing to rear of vehicle already. I used this one from Radio Shack. Model: 275-233 Catalog #: 2750233 0.5-AMP SPST REED RELAY AT 12VDC. This set up should be used to turn on multiple amps and relieve the head unit circuit. No tiny wire to run either. Although if this wire is just attached to RCA prior to install for a 1 amp install then this is the easiest way. If you use the relay then remember to fuse it to protect the head unit circuit. **Q: Does this amp provides High (Speaker) Level Inputs so it could be connected to a factory head unit?** A: I know this is late, but it may help others. Yes it does and you can tie into signal at rear speaker wires. The built in crossover will allow use of a sub woofer. Only drawback to this set up is that if you turn down head unit bass for doors ect. it also affects sub amp. HU built in crossover would be better for a balanced and more adjustable sound. This requires the HU to be upgraded however. A line output converter is a good option too even if you have low input ability. Makes for a neater install IMO. Bottom line is that it is dooable. Good amp too. Birthsheet is 648 watt @ 2 ohm 14.4 v on mine. In vehicle at idle in real life I average 629 using amp draw and voltage formula, I also own the P300-1 which pushes about 415 @ 2 ohm real life wattage. Birth sheet of 426. Banging for years in wife's ride on that one no issues. The new one rocks good so far in my ride. Love these amps. So much power for the size. Also as a D class amp they are efficient and take less away from the vehicle power system causing less strain. Bang some high power AB amps for a few years and your whooping on that alternator and battery shortening their lives. Less light dimming too. **Q: Does the R500x1D come with the remote or is it sold separately?** A: It comes with the remote. I thought it didn't so I bought one for it and it already comes with it so I have two now ## Customer Reviews ### ⭐⭐ 到着予定日はあてになりません *by た***し on March 14, 2018* まだ車に付けていないので動作確認できていませんが、商品は綺麗で良かったです。一方で、到着予定日の翌日に発送しており、配送遅延が明らかだったのに事前に連絡がなかったなど残念な点があり、マイナス評価とさせて頂きます。 ### ⭐⭐⭐ 見出しって何ですか *by コ***ウ on November 7, 2014* 今のデッキに対応してなくて残念ですが！工夫して使おうと思ってます！ ## Frequently Bought Together - Rockford Fosgate R500X1D Prime 1-Channel Class D Amplifier - BOSS Audio Systems KIT2 8 Gauge Complete Car Amplifier Installation Wiring Kit with Power Cables, Ground Cables, Turn-On Wire, Speaker Wire, Terminals - Kicker 46KISLOC2 K-Series Stereo Line-Output Converter w/Remote Turn-On Output --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/740146527-rockford-r500x1d-1-channel-amplifier-small-digital-mono-power-amplifier](https://www.desertcart.us/products/740146527-rockford-r500x1d-1-channel-amplifier-small-digital-mono-power-amplifier) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-19*
